Current Drug Targeting using siRNAbased Nano Therapeutics for Pulmonary Diseases
Curr Pharm Des. 2022 Jul 27. doi: 10.2174/1381612828666220727144223. Online ahead of print.ABSTRACTThe importance of siRNA in nano drug delivery systems to target important pulmonary disorders such as chronic obstructive pulmonary disease (COPD), asthma, lung cancer, and others is reviewed in this perspective. The great majority of lung illnesses are caused by protein misfolding. As a result, siRNA-based therapies are increasingly being used to target the gene. Given the difficulties of delivering bare siRNA, siRNA protection may ensure its efficacy in gene therapy. These issues could be solved with a nano-based siRNA deli...

From Genesis To Revelation: The Role Of Inflammatory Mediators In Chronic Respiratory Diseases And Their Control By Nucleic Acid-Based Drugs.
Abstract Asthma, chronic obstructive pulmonary disease, cystic fibrosis, and idiopathic pulmonary fibrosis, are among the most common chronic diseases and their prevalence is increasing. Each of these diseases is characterized by the secretion of cytokines and pro-inflammatory molecules which are thought to play a critical role in their pathogenesis. Moreover, immune cells, particularly neutrophils, macrophages and dendritic cells as well structural cells such as epithelial and airway smooth muscle cells are also involved in the pathogenic cycle of these diseases. There is a pressing need for the development of ne...

A hyaluronan-based nanosystem enables combined anti-inflammation of mTOR gene silencing and pharmacotherapy
In this study, we synthesized a hyaluronan-based ROS-sensitive polymer which was expected to release loaded chemical drugs in inflammatory environment and further developed a stable and nontoxic co-delivery nanosystem of siRNA targeting autophagy suppressive gene and chemotherapeutic agents. The in vitro transfection study of this nanosystem revealed improved intracellular accumulation of siRNA and excellent gene silencing efficacy comparable to that of conventional cationic liposome. Moreover, the mRNA expression of inflammatory cytokines was remarkably decreased by our nanosystem. Considering its biocompatibility, transf...
