Trends in Medical Research published a research work conducted by Junjun Shang, investigates the impact of Toll-Like Receptor 4 (TLR4) on Angiotensin II (Ang II)-induced cardiac hypertrophy in mice. The study explores the application of TAK-242, a TLR4 inhibitor, and its effects on various cardiac parameters. Results show that TAK-242 reduces heart mass index, cardiac-tibial ratio, cardiomyocyte cross-sectional area, and ameliorates fibrosis. It inhibits the expression of vimentin and TLR4, thereby reducing Ang II-induced cardiac hypertrophy. The study suggests that TLR4 is a key target in cardiac hypertrophy, providing new insights for clinical treatment and potential drug development.
