Myasthenia gravis (MG) is a chronic autoimmune disorder that involves the targeting of neuromuscular junctions and is primarily driven by autoantibodies against the acetylcholine receptor (AChR). While genetic susceptibility is a factor, environmental triggers, particularly viral infections, are being increasingly investigated as potential contributors to MG pathogenesis. This review examines the complex interplay between vira...

Alphaviruses, including Mayaro virus (MAYV) and Chikungunya virus (CHIKV), pose a growing public health threat, with increasing reports worldwide and no licensed antiviral treatments available. This study evaluated the antiviral activity of pyridine-3-carbohydrazide (P-3-C) against MAYV (strains BeAr and TRVL) and CHIKV (strain La Reunion, LR). Vero E6 or U-2OS cells were infected and treated with P-3-C for 24 h, and cell viab...
