    Biomedical applications of polysaccharide nanoparticles for chronic inflammatory disorders: Focus on rheumatoid arthritis, diabetes and organ fibrosis
    (Elsevier Ltd, 2021-11-22T00:00:00) Allawadhi, Prince; Singh, Vishakha; Govindaraj, Kannan; Khurana, Isha; Sarode, Lopmudra P.; Navik, Umashanker; Banothu, Anil Kumar; Weiskirchen, Ralf; Bharani, Kala Kumar; Khurana, Amit
    Polysaccharides are biopolymers distinguished by their complex secondary structures executing various roles in microorganisms, plants, and animals. They are made up of long monomers of similar type or as a combination of other monomeric chains. Polysaccharides are considered superior as compared to other polymers due to their diversity in charge and size, biodegradability, abundance, bio-compatibility, and less toxicity. These natural polymers are widely used in designing of nanoparticles (NPs) which possess wide applications in therapeutics, diagnostics, delivery and protection of bioactive compounds or drugs. The side chain reactive groups of polysaccharides are advantageous for functionalization with nanoparticle-based conjugates or therapeutic agents such as small molecules, proteins, peptides and nucleic acids. Polysaccharide NPs show excellent pharmacokinetic and drug delivery properties, facilitate improved oral absorption, control the release of drugs, increases in vivo retention capability, targeted delivery, and exert synergistic effects. This review updates the usage of polysaccharides based NPs particularly cellulose, chitosan, hyaluronic acid, alginate, dextran, starch, cyclodextrins, pullulan, and their combinations with promising applications in diabetes, organ fibrosis and arthritis. � 2021 Elsevier Ltd

    Various Cellular and Molecular Axis Involved in the Pathogenesis of Asthma
    (Springer Nature, 2021-07-02T00:00:00) Bhatti, Gurjit Kaur; Khurana, Amit; Garabadu, Debapriya; Gupta, Prashant; Jawalekar, Snehal Sainath; Bhatti, Jasvinder Singh; Navik, Umashanker
    Asthma is a chronic inflammatory disease described by impaired lung function, airway hyperresponsiveness, episodic wheezing, and dyspnea. Asthma prevalence has risen drastically, and it is estimated that more than 339 million individuals worldwide had asthma with marked heterogeneity in pathophysiology and etiology. Several factors involved in the progression and development of asthma include allergens, pollutants, obesity, viruses, antigens, and many more, eliciting strong inflammatory and immune responses, causing airflow obstruction, and tightening of respiratory smooth muscle causing the characteristic asthma symptoms. Multiple complex molecular pathways are involved in asthma pathophysiologies such as immunoglobulin E, cytokines, nitric oxide, dendritic cells, leukotrienes, oxidative stress, and inflammatory infiltrate of mast cells, neutrophils, eosinophils, lymphocytes, innate immunity, and many more. The current chapter focuses on illustrating the various molecular pathways that contribute to asthma development and its progression. � The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
