The malfunction of lymphatic drainage that occurs in lymphedema leads to excessive cholesterol accumulation in the affected skin and lymphatic vessels, causing inflammation and fibrosis. However, surgery and the chemical reduction of accumulated cholesterol with cyclodextrin reduce inflammation and regenerate lymphatic vessels. Cholesterol is a potential therapeutic target for treating lymphedema, according to this study published on Feb. 11, 2026, in Nature by Veronique Angeli and her colleagues.
Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer, representing approximately 75-85% of all cases. Often considered preventable, primary liver cancer ranks as the sixth most frequently diagnosed cancer and the third leading cause of cancer deaths worldwide. Through a multi-institutional effort, researchers have identified activated ATF6α as a driver of HCC that suppresses immune defenses, predicts response to immune checkpoint therapy, and represents a potential target for intervention.
The neural and neuroimmune mechanisms behind myocardial infarction-triggered cardiac events, immune responses and activation of the nervous system remain largely unexplored. The heart and the brain talk to each other in what is known as cardioception. This communication between the two organs is orchestrated through neurons of the vagus nerve or the dorsal root ganglia, among others. Researchers from the University of California, San Diego have now shown that the dynamics of these interactions may play a crucial role in modulating inflammation, repair and cardiac functioning.
