Apomorphine is a novel necroptosis inhibitor targeting mixed lineage kinase domain-like protein oligomerization

Apomorphine (APO), an FDA-approved drug for Parkinson's disease, has been identified as a novel necroptosis inhibitor targeting mixed lineage kinase domain-like protein (MLKL) oligomerization. This study demonstrates that Ox-APO, the oxidized form of APO, effectively inhibits necroptosis in murine models of inflammatory bowel disease and liver injury. The findings suggest that Ox-APO could serve as a promising candidate for treating necroptosis-related diseases, highlighting its potential for broader therapeutic applications.

Central Zika virus infection causes hypothalamic inflammation and persistent insulin resistance in adult mice

Zika virus (ZIKV) infection in adult mice results in significant hypothalamic inflammation and persistent insulin resistance, even after acute inflammation resolves. The study demonstrates that ZIKV invades the hypothalamus, triggering inflammatory responses that disrupt insulin signaling and alter neuropeptide expression critical for glucose homeostasis. Despite the resolution of inflammation, insulin resistance persists, suggesting a potential link between viral infections and long-term metabolic disorders such as obesity and type 2 diabetes. These findings underscore the importance of understanding the metabolic consequences of ZIKV neuroinvasion.
