    Aim: In the present study boswellic acids-loaded chitosan nanoparticles were synthesized using ionic gelation technique. The influence of independent variables were studied and optimized on dependent variables using central composite design. Methodology & results: The designed nanoparticles were observed spherical in shape with an average size of 67.5-187.2 nm and have also shown an excellent entrapment efficiency (80.06 ± 0.48). The cytotoxicity assay revealed enhanced cytotoxicity for drug-loaded nanoparticles in contrast to the free drug having an IC50 value of 17.29 and 29.59 μM, respectively. Flow cytometry confirmed that treatment of cells with 40 μg/ml had arrested 22.75 ± 0.3% at SubG0 phase of the cell cycle when compared with untreated A459 cells. The observed results justified the boswellic acids-loaded chitosan nanoparticles were effective due to greater cellular uptake, sustained intercellular drug retention and enhanced antiproliferative effect by inducing apoptosis.

    Non-communicable, chronic respiratory diseases (CRDs) affect millions of individuals worldwide. The course of these CRDs (asthma, chronic obstructive pulmonary disease, and cystic fibrosis) are often punctuated by microbial infections that may result in hospitalization and are associated with increased risk of morbidity and mortality, as well as reduced quality of life. Interleukin-13 (IL-13) is a key protein that regulates airway inflammation and mucus hypersecretion. There has been much interest in IL-13 from the last two decades. This cytokine is believed to play a decisive role in the exacerbation of inflammation during the course of viral infections, especially, in those with pre-existing CRDs. Here, we discuss the common viral infections in CRDs, as well as the potential role that IL-13 plays in the virus-induced disease pathogenesis of CRDs. We also discuss, in detail, the immune-modulation potential of IL-13 that could be translated to in-depth studies to develop IL-13-based therapeutic entities.

    Regardless of advances in detection and treatment, breast cancer affects about 1.5 million women all over the world. Since the last decade, genome-wide association studies (GWAS) have been extensively conducted for breast cancer to define the role of miRNA as a tool for diagnosis, prognosis and therapeutics. MicroRNAs are small, non-coding RNAs that are associated with the regulation of key cellular processes such as cell multiplication, differentiation, and death. They cause a disturbance in the cell physiology by interfering directly with the translation and stability of a targeted gene transcript. MicroRNAs (miRNAs) constitute a large family of non-coding RNAs, which regulate target gene expression and protein levels that affect several human diseases and are suggested as the novel markers or therapeutic targets, including breast cancer. MicroRNA (miRNA) alterations are not only associated with metastasis, tumor genesis but also used as biomarkers for breast cancer diagnosis or prognosis. These are explained in detail in the following review. This review will also provide an impetus to study the role of microRNAs in breast cancer.

    Wadhwa R, Paudel KR, Mehta M, Shukla SD, Sunkara K, Prasher P, et al.
    CNS Neurol Disord Drug Targets, 2020;19(9):698-708.
    PMID: 33109069 DOI: 10.2174/1871527319999200817112427
    Tobacco smoke is not only a leading cause for chronic obstructive pulmonary disease, cardiovascular disorders, and lung and oral cancers, but also causes neurological disorders such as Alzheimer 's disease. Tobacco smoke consists of more than 4500 toxic chemicals, which form free radicals and can cross blood-brain barrier resulting in oxidative stress, an extracellular amyloid plaque from the aggregation of amyloid β (Aβ) peptide deposition in the brain. Further, respiratory infections such as Chlamydia pneumoniae, respiratory syncytial virus have also been involved in the induction and development of the disease. The necessary information collated on this review has been gathered from various literature published from 1995 to 2019. The review article sheds light on the role of smoking and respiratory infections in causing oxidative stress and neuroinflammation, resulting in Alzheimer's disease (AD). This review will be of interest to scientists and researchers from biological and medical science disciplines, including microbiology, pharmaceutical sciences and the translational researchers, etc. The increasing understanding of the relationship between chronic lung disease and neurological disease is two-fold. First, this would help to identify the risk factors and possible therapeutic interventions to reduce the development and progression of both diseases. Second, this would help to reduce the probable risk of development of AD in the population prone to chronic lung diseases.

    Prasher P, Sharma M, Mehta M, Paudel KR, Satija S, Chellappan DK, et al.
    Chem Biol Interact, 2020 Jul 01;325:109125.
    PMID: 32376238 DOI: 10.1016/j.cbi.2020.109125
    The apparent predicament of the representative chemotherapy for managing respiratory distress calls for an obligatory deliberation for identifying the pharmaceuticals that effectively counter the contemporary intricacies associated with target disease. Multiple, complex regulatory pathways manifest chronic pulmonary disorders, which require chemotherapeutics that produce composite inhibitory effect. The cost effective natural product based molecules hold a high fervor to meet the prospects posed by current respiratory-distress therapy by sparing the tedious drug design and development archetypes, present a robust standing for the possible replacement of the fading practice of poly-pharmacology, and ensure the subversion of a potential disease relapse. This study summarizes the experimental evidences on natural products moieties and their components that illustrates therapeutic efficacy on respiratory disorders.
  7. Fulltext Concepts of advanced therapeutic delivery systems for the management of remodeling and inflammation in airway diseases
    Dhanjal DS, Sharma P, Mehta M, Tambuwala MM, Prasher P, Paudel KR, et al.
    Future Med Chem, 2022 Feb;14(4):271-288.
    PMID: 35019757 DOI: 10.4155/fmc-2021-0081
    Chronic respiratory disorders affect millions of people worldwide. Pathophysiological changes to the normal airway wall structure, including changes in the composition and organization of its cellular and molecular constituents, are referred to as airway remodeling. The inadequacy of effective treatment strategies and scarcity of novel therapies available for the treatment and management of chronic respiratory diseases have given rise to a serious impediment in the clinical management of such diseases. The progress made in advanced drug delivery, has offered additional advantages to fight against the emerging complications of airway remodeling. This review aims to address the gaps in current knowledge about airway remodeling, the relationships between remodeling, inflammation, clinical phenotypes and the significance of using novel drug delivery methods.
  8. Fulltext Agarwood Oil Nanoemulsion Attenuates Cigarette Smoke-Induced Inflammation and Oxidative Stress Markers in BCi-NS1.1 Airway Epithelial Cells
    De Rubis G, Paudel KR, Manandhar B, Singh SK, Gupta G, Malik R, et al.
    Nutrients, 2023 Feb 17;15(4).
    PMID: 36839377 DOI: 10.3390/nu15041019
    Chronic obstructive pulmonary disease (COPD) is an irreversible inflammatory respiratory disease characterized by frequent exacerbations and symptoms such as cough and wheezing that lead to irreversible airway damage and hyperresponsiveness. The primary risk factor for COPD is chronic cigarette smoke exposure, which promotes oxidative stress and a general pro-inflammatory condition by stimulating pro-oxidant and pro-inflammatory pathways and, simultaneously, inactivating anti-inflammatory and antioxidant detoxification pathways. These events cause progressive damage resulting in impaired cell function and disease progression. Treatments available for COPD are generally aimed at reducing the symptoms of exacerbation. Failure to regulate oxidative stress and inflammation results in lung damage. In the quest for innovative treatment strategies, phytochemicals, and complex plant extracts such as agarwood essential oil are promising sources of molecules with antioxidant and anti-inflammatory activity. However, their clinical use is limited by issues such as low solubility and poor pharmacokinetic properties. These can be overcome by encapsulating the therapeutic molecules using advanced drug delivery systems such as polymeric nanosystems and nanoemulsions. In this study, agarwood oil nanoemulsion (agarwood-NE) was formulated and tested for its antioxidant and anti-inflammatory potential in cigarette smoke extract (CSE)-treated BCi-NS1.1 airway basal epithelial cells. The findings suggest successful counteractivity of agarwood-NE against CSE-mediated pro-inflammatory effects by reducing the expression of the pro-inflammatory cytokines IL-1α, IL-1β, IL-8, and GDF-15. In addition, agarwood-NE induced the expression of the anti-inflammatory mediators IL-10, IL-18BP, TFF3, GH, VDBP, relaxin-2, IFN-γ, and PDGF. Furthermore, agarwood-NE also induced the expression of antioxidant genes such as GCLC and GSTP1, simultaneously activating the PI3K pro-survival signalling pathway. This study provides proof of the dual anti-inflammatory and antioxidant activity of agarwood-NE, highlighting its enormous potential for COPD treatment.

    Alharbi KS, Javed Shaikh MA, Imam SS, Alshehri S, Ghoneim MM, Almalki WH, et al.
    Curr Med Chem, 2023;30(18):2061-2074.
    PMID: 36415096 DOI: 10.2174/0929867330666221122115212
    More than 10 million people worldwide have Alzheimer's disease (AD), a degenerative neurological illness and the most prevalent form of dementia. AD's progression in memory loss, cognitive deterioration, and behavioral changes are all symptoms. Amyloid-beta 42 (Aβ42), the hyperphosphorylated forms of microtubule-associated tau protein, and other cellular and systemic alterations are all factors that contribute to cognitive decline in AD. Rather than delivering a possible cure, present therapy strategies focus on reducing disease symptoms. It has long been suggested that various naturally occurring small molecules (plant extract products and microbiological isolates, for example) could be beneficial in preventing or treating disease. Small compounds, such as flavonoids, have attracted much interest recently due to their potential to alleviate cellular stress. Flavonoids have been proven helpful in various ways, including antioxidants, anti-inflammatory agents, and anti-apoptotic agents, but their mechanism remains unknown. The flavonoid therapy of Alzheimer's disease focuses on this review, which includes a comprehensive literature analysis.

    PMID: 37183464 DOI: 10.2174/1871530323666230512154634
    BACKGROUND: In the last few decades, it has been largely perceived that the factors affecting the immune system and its varying pathways lead to the pathological progression of inflammation and inflammatory conditions. Chronic inflammation also contributes to common diseases, such as diabetes mellitus, ischemic heart disease, cancer, chronic renal inflammatory disease, non-alcoholic fatty hepat-ic disease, autoimmune diseases and neurodegenerative diseases.

    OBJECTIVE: Interestingly, plant sources and secondary metabolites from plants have been increasingly employed in managing acute and chronic inflammatory diseases for centuries. Boswellic acids are pentacyclic triterpenoidal moieties obtained from the oleo gum resin of different Boswellia species.

    METHODS: Detailed data was collected revealing the anti-inflammatory potential of Boswellic acids through various databases.

    RESULT: These are pharmacologically active agents that possess promising anti-inflammatory, anti-arthritic, antirheumatic, anti-diarrheal, anti-hyperlipidemic, anti-asthmatic, anti-cancer, and anti-microbial effects.

    CONCLUSION: Boswellic acids have been in use since ancient times primarily to treat acute and chronic inflammatory diseases. This review discusses the various mechanisms underlying the inflammatory process and the necessity of such natural products as a medication to treat inflammatory diseases. In addition, a discussion has also been extended to understand the primary targets involved in inflammation. The review further explores the therapeutic potential of boswellic acids in.

  11. Unraveling the role of glial cell line-derived neurotrophic factor in the treatment of Parkinson's disease
    Kakoty V, Sarathlal KC, Kaur P, Wadhwa P, Vishwas S, Khan FR, et al.
    Neurol Sci, 2024 Apr;45(4):1409-1418.

    Parkinson's disease is the second most common neurodegenerative condition with its prevalence projected to 8.9 million individuals globally in the year 2019. Parkinson's disease affects both motor and certain non-motor functions of an individual. Numerous research has focused on the neuroprotective effect of the glial cell line-derived neurotrophic factor (GDNF) in Parkinson's disease. Discovered in 1993, GDNF is a neurotrophic factor identified from the glial cells which was found to have selective effects on promoting survival and regeneration of certain populations of neurons including the dopaminergic nigrostriatal pathway. Given this property, recent studies have focused on the exogenous administration of GDNF for relieving Parkinson's disease-related symptoms both at a pre-clinical and a clinical level. This review will focus on enumerating the molecular connection between Parkinson's disease and GDNF and shed light on all the available drug delivery approaches to facilitate the selective delivery of GDNF into the brain paving the way as a potential therapeutic candidate for Parkinson's disease in the future.
  12. Fulltext 18-β-glycyrrhetinic acid-loaded polymeric nanoparticles attenuate cigarette smoke-induced markers of impaired antiviral response in vitro
    De Rubis G, Paudel KR, Yeung S, Mohamad S, Sudhakar S, Singh SK, et al.
    Pathol Res Pract, 2024 May;257:155295.
    PMID: 38603841 DOI: 10.1016/j.prp.2024.155295
    Tobacco smoking is a leading cause of preventable mortality, and it is the major contributor to diseases such as COPD and lung cancer. Cigarette smoke compromises the pulmonary antiviral immune response, increasing susceptibility to viral infections. There is currently no therapy that specifically addresses the problem of impaired antiviral response in cigarette smokers and COPD patients, highlighting the necessity to develop novel treatment strategies. 18-β-glycyrrhetinic acid (18-β-gly) is a phytoceutical derived from licorice with promising anti-inflammatory, antioxidant, and antiviral activities whose clinical application is hampered by poor solubility. This study explores the therapeutic potential of an advanced drug delivery system encapsulating 18-β-gly in poly lactic-co-glycolic acid (PLGA) nanoparticles in addressing the impaired antiviral immunity observed in smokers and COPD patients. Exposure of BCi-NS1.1 human bronchial epithelial cells to cigarette smoke extract (CSE) resulted in reduced expression of critical antiviral chemokines (IP-10, I-TAC, MIP-1α/1β), mimicking what happens in smokers and COPD patients. Treatment with 18-β-gly-PLGA nanoparticles partially restored the expression of these chemokines, demonstrating promising therapeutic impact. The nanoparticles increased IP-10, I-TAC, and MIP-1α/1β levels, exhibiting potential in attenuating the negative effects of cigarette smoke on the antiviral response. This study provides a novel approach to address the impaired antiviral immune response in vulnerable populations, offering a foundation for further investigations and potential therapeutic interventions. Further studies, including a comprehensive in vitro characterization and in vivo testing, are warranted to validate the therapeutic efficacy of 18-β-gly-PLGA nanoparticles in respiratory disorders associated with compromised antiviral immunity.

  14. Fulltext Non-coding RNA: A key regulator in the Glutathione-GPX4 pathway of ferroptosis
    Hussain S, Gupta G, Shahwan M, Bansal P, Kaur H, Deorari M, et al.
    Noncoding RNA Res, 2024 Dec;9(4):1222-1234.
    PMID: 39036600 DOI: 10.1016/j.ncrna.2024.05.007
    Ferroptosis, a form of regulated cell death, has emerged as a crucial process in diverse pathophysiological states, encompassing cancer, neurodegenerative ailments, and ischemia-reperfusion injury. The glutathione (GSH)-dependent lipid peroxidation pathway, chiefly governed by glutathione peroxidase 4 (GPX4), assumes an essential part in driving ferroptosis. GPX4, as the principal orchestrator of ferroptosis, has garnered significant attention across cancer, cardiovascular, and neuroscience domains over the past decade. Noteworthy investigations have elucidated the indispensable functions of ferroptosis in numerous diseases, including tumorigenesis, wherein robust ferroptosis within cells can impede tumor advancement. Recent research has underscored the complex regulatory role of non-coding RNAs (ncRNAs) in regulating the GSH-GPX4 network, thus influencing cellular susceptibility to ferroptosis. This exhaustive review endeavors to probe into the multifaceted processes by which ncRNAs control the GSH-GPX4 network in ferroptosis. Specifically, we delve into the functions of miRNAs, lncRNAs, and circRNAs in regulating GPX4 expression and impacting cellular susceptibility to ferroptosis. Moreover, we discuss the clinical implications of dysregulated interactions between ncRNAs and GPX4 in several conditions, underscoring their capacity as viable targets for therapeutic intervention. Additionally, the review explores emerging strategies aimed at targeting ncRNAs to modulate the GSH-GPX4 pathway and manipulate ferroptosis for therapeutic advantage. A comprehensive understanding of these intricate regulatory networks furnishes insights into innovative therapeutic avenues for diseases associated with perturbed ferroptosis, thereby laying the groundwork for therapeutic interventions targeting ncRNAs in ferroptosis-related pathological conditions.

    Polycystic ovarian syndrome (PCOS) is one of the chief causes of infertility in women of reproductive age. Several drugs belonging to the oral contraceptive class have been approved for the treatment of PCOS. Nonetheless, the capability to target only a few symptoms of PCOS and fatal side effects are key hurdles to their use. Therefore, repurposing existing drugs can be promising in managing PCOS efficiently. Drugs from different pharmacological classes like antidiabetics (metformin, rosiglitazone, pioglitazone, and semaglutide), statins (simvastatin and atorvastatin), antiandrogen drugs (finasteride and flutamide), etc. demonstrated significant potential in managing PCOS. The present review offers a comprehensive overview of all the medications examined as potential repurposed options for the efficient treatment of PCOS. The pathogenesis of PCOS, existing therapies for PCOS and their challenges, drug repurposing and its significance is also explained. The small-molecular drugs from various pharmacological classes and different phytoceuticals repurposed against PCOS are discussed along with their anti-PCOS activity mechanisms. Moreover, novel drug targets responsible for PCOS and opportunities for drug repurposing are briefed. The repurposed drugs in clinical trials for PCOS and drug repurposing challenges are discussed. Thus, drug repurposing can serve as a potential way to effectively treat PCOS, reducing the extent of infertility and improving the quality of life of women.
  16. Fulltext The impact of airborne particulate matter-based pollution on the cellular and molecular mechanisms in chronic obstructive pulmonary disease (COPD)
    Taylor-Blair HC, Siu ACW, Haysom-McDowell A, Kokkinis S, Bani Saeid A, Chellappan DK, et al.
    Sci Total Environ, 2024 Dec 01;954:176413.
    PMID: 39322084 DOI: 10.1016/j.scitotenv.2024.176413
    Inhalation of particulate matter (PM), one of the many components of air pollution, is associated with the development and exacerbation of chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD). COPD is one of the leading causes of global mortality and morbidity, with a paucity of therapeutic options and a significant contributor to global health expenditure. This review aims to provide a mechanistic understanding of the cellular and molecular pathways that lead to the development of COPD following chronic PM exposure. Our review describes how the inhalation of PM can lead to lung parenchymal destruction and cellular senescence due to chronic pulmonary inflammation and oxidative stress. Following inhalation of PM, significant increases in a range of pro-inflammatory cytokines, mediated by the nuclear factor kappa B pathway are reported. This review also highlights how the inhalation of PM can lead to deleterious chronic oxidative stress persisting in the lung post-exposure. Furthermore, our work summarises how PM inhalation can lead to airway remodelling, with increases in pro-fibrotic cytokines and collagen deposition, typical of COPD. This paper also accentuates the interconnection and possible synergism between the pathophysiological mechanisms leading to COPD. Our work emphasises the serious health consequences of PM exposure on respiratory health. Elucidation of the cellular and molecular mechanisms can provide insight into possible therapeutic options. Finally, this review should serve as a stark reminder of the need for genuine action on air pollution to decrease the associated health burden on our growing global population.
  17. Fulltext Vitamin D-A prominent immunomodulator to prevent COVID-19 infection
    Ashique S, Gupta K, Gupta G, Mishra N, Singh SK, Wadhwa S, et al.
    Int J Rheum Dis, 2023 Jan;26(1):13-30.
    PMID: 36308699 DOI: 10.1111/1756-185X.14477
    COVID-19 remains a life-threatening infectious disease worldwide. Several bio-active agents have been tested and evaluated in an effort to contain this disease. Unfortunately, none of the therapies have been successful, owing to their safety concerns and the presence of various adverse effects. Various countries have developed vaccines as a preventive measure; however, they have not been widely accepted as effective strategies. The virus has proven to be exceedingly contagious and lethal, so finding an effective treatment strategy has been a top priority in medical research. The significance of vitamin D in influencing many components of the innate and adaptive immune systems is examined in this study. This review aims to summarize the research on the use of vitamin D for COVID-19 treatment and prevention. Vitamin D supplementation has now become an efficient option to boost the immune response for all ages in preventing the spread of infection. Vitamin D is an immunomodulator that treats infected lung tissue by improving innate and adaptive immune responses and downregulating the inflammatory cascades. The preventive action exerted by vitamin D supplementation (at a specific dose) has been accepted by several observational research investigations and clinical trials on the avoidance of viral and acute respiratory dysfunctions. To assess the existing consensus about vitamin D supplementation as a strategy to treat and prevent the development and progression of COVID-19 disease, this review intends to synthesize the evidence around vitamin D in relation to COVID-19 infection.
  18. Rutin loaded liquid crystalline nanoparticles inhibit non-small cell lung cancer proliferation and migration in vitro
    Paudel KR, Wadhwa R, Tew XN, Lau NJX, Madheswaran T, Panneerselvam J, et al.
    Life Sci, 2021 Jul 01;276:119436.
    PMID: 33789146 DOI: 10.1016/j.lfs.2021.119436
    Non-small cell lung cancer (NSCLC) is one of the major causes of cancer-related mortality globally. Despite the availability of therapeutic options, the improvement in patient survival is yet to be achieved. Recent advances in natural product (e.g., Rutin) research, therapeutic nanotechnology and especially the combination of both could aid in achieving significant improvements in the treatment or management of NSCLC. In this study, we explore the anti-cancer activity of Rutin-loaded liquid crystalline nanoparticles (LCNs) in an in vitro model where we have employed the A549 human lung epithelial carcinoma cell line. The anti-proliferative activity was determined by MTT and Trypan blue assays, whereas, the anti-migratory activity was evaluated by the scratch wound healing assay and a modified Boyden chamber assay. We also evaluated the anti-apoptotic activity by Annexin V-FITC staining, and the colony formation activity was studied using crystal violet staining. Here, we report that Rutin-LCNs showed promising anti-proliferative and anti-migratory activities. Furthermore, Rutin-LCNs also induced apoptosis in the A549 cells and inhibited colony formation. The findings warrant further detailed and in-depth anti-cancer mechanistic studies of Rutin-LCNs with a focus towards a potential therapeutic option for NSCLC. LCNs may help to enhance the solubility of Rutin used in the treatment of lung cancer and hence enhance the anticancer effect of Rutin.
  19. Anti-inflammatory and anticancer activities of Naringenin-loaded liquid crystalline nanoparticles in vitro
    Wadhwa R, Paudel KR, Chin LH, Hon CM, Madheswaran T, Gupta G, et al.
    J Food Biochem, 2021 01;45(1):e13572.
    PMID: 33249629 DOI: 10.1111/jfbc.13572
    In this study, we had developed Naringenin-loaded liquid crystalline nanoparticles (LCNs) and investigated the anti-inflammatory and anticancer activities of Naringenin-LCNs against human airway epithelium-derived basal cells (BCi-NS1.1) and human lung epithelial carcinoma (A549) cell lines, respectively. The anti-inflammatory potential of Naringenin-LCNs evaluated by qPCR revealed a decreased expression of IL-6, IL-8, IL-1β, and TNF-α in lipopolysaccharide-induced BCi-NS1.1 cells. The activity of LCNs was comparable to the positive control drug Fluticasone propionate (10 nM). The anticancer activity was studied by evaluating the antiproliferative (MTT and trypan blue assays), antimigratory (scratch wound healing assay, modified Boyden chamber assay, and immunoblot), and anticolony formation activity in A549 cells. Naringenin LCNs showed promising antiproliferative, antimigratory, and anticolony formation activities in A549 cells, in vitro. Therefore, based on our observations and results, we conclude that Naringenin-LCNs may be employed as a potential therapy-based intervention to ameliorate airway inflammation and to inhibit the progression of lung cancer. PRACTICAL APPLICATIONS: Naringenin was encapsulated into liquid crystalline nanoparticles, thus, attributing to their sustained-release nature. In addition, Naringenin-loaded LCNs efficiently reduced the levels of pro-inflammatory markers, namely, IL-1β, IL-6, TNF-α, and IL-8. In addition, the Naringenin-loaded LCNs also possess potent anticancer activity, when tested in the A549 cell line, as revealed by the inhibition of proliferation and migration of cells. They also attenuated colony formation and induced apoptosis in the A549 cells. The findings from our study could form the basis for future research that may be translated into an in vivo model to validate the possible therapeutic alternative for lung cancer using Naringenin-loaded LCNs. In addition, the applications of Naringenin-loaded LCNs as an intervention would be of great interest to biological, formulation and respiratory scientists and clinicians.
  20. Cellular signalling pathways mediating the pathogenesis of chronic inflammatory respiratory diseases: an update
    Mehta M, Dhanjal DS, Paudel KR, Singh B, Gupta G, Rajeshkumar S, et al.
    Inflammopharmacology, 2020 Aug;28(4):795-817.
    PMID: 32189104 DOI: 10.1007/s10787-020-00698-3
    Respiratory disorders, especially non-communicable, chronic inflammatory diseases, are amongst the leading causes of mortality and morbidity worldwide. Respiratory diseases involve multiple pulmonary components, including airways and lungs that lead to their abnormal physiological functioning. Several signaling pathways have been reported to play an important role in the pathophysiology of respiratory diseases. These pathways, in addition, become the compounding factors contributing to the clinical outcomes in respiratory diseases. A range of signaling components such as Notch, Hedgehog, Wingless/Wnt, bone morphogenetic proteins, epidermal growth factor and fibroblast growth factor is primarily employed by these pathways in the eventual cascade of events. The different aberrations in such cell-signaling processes trigger the onset of respiratory diseases making the conventional therapeutic modalities ineffective. These challenges have prompted us to explore novel and effective approaches for the prevention and/or treatment of respiratory diseases. In this review, we have attempted to deliberate on the current literature describing the role of major cell signaling pathways in the pathogenesis of pulmonary diseases and discuss promising advances in the field of therapeutics that could lead to novel clinical therapies capable of preventing or reversing pulmonary vascular pathology in such patients.
