Abstract

Objective: Inflammation is a complex reaction present in numerous disorders. Indomethacin, a compound possessing an indoline core, is a Nonsteroidal Anti-Inflammatory Drug (NSAID) that is commonly prescribed for inflammation and pain. The actin network, plays a major role in cellular activities and it’s regulated by by Rho GTPases has important implications for cellular dynamics and orientation. In this research, we explore the effects of indomethacin on the inflammatory response as mediated via RhoA and pyrin inflammatory complexes using an inflammatory disease model with relation actin cytoskeleton.
Materials and Methods: This study used Western blotting to examine the impact of indomethacin on the assembly processes related to the pyrin inflammasome complex and the RhoA signaling pathway in Lipopolysaccharide-stimulated THP-1 cells. Actin-indomethacin interaction was analyzed by Differential Scanning Fluorimetry (DSF).
Results: We found that while the expression levels of pyrin decreased, phosphorylated-RhoA increased but overall RhoA levels did not change. The equilibrium dissociation constant (KD) for the G-actin-indomethacin complex was calculated to be 9.591± 1.608 ng/mL (R2 = 0.8582) using ∆Tm measurements of indomethacin by DSF.
Conclusion: Moreover, the effects of indomethacin on inflammation pathways may provide insight into the molecular mechanisms of pyrin inflammasome formation in various autoimmune diseases.
