Protective effect of Apremilast against LPS-induced acute lung injury via modulation of oxidative stress and inflammation

Lung injuries are attributed due to exposure to Drugs or chemicals. One of the important challenging sit-uations for the clinicians is to manage treatments of different diseases with acute lung injury (ALI). The objective of this study was to investigate the possible protective mechanisms and action of a novel Phosphodiesterase-4 inhibitor "Apremilast " (AP) in lipopolysaccharide (LPS)-induced lung injury. Blood sample from each animals were collected in a vacuum blood collection tube. The rat lungs were isolated for oxidative stress assessment, western blot analysis and their mRNA expressions using RT-PCR. Exposure of LPS in rats causes significant increase in oxidative stress, activates the pro-inflammatory cytokines release like tissue necrotic factor-alpha (TNF-a), interleukin-10 (IL-10) and interleukin-6 (IL -6), modulated gene expression, protein expression and histopathological changes which were reversed by administration of AP. Finding of the research enlighten the protective role of AP against LPS-induced ALI. (C) 2022 The Authors. Published by Elsevier B.V. on behalf of King Saud University.& nbsp;
