This study shows that aging-induced CD44 in hepatocytes activates the IL6/JAK/STAT3 pathway, leading to impaired T cell function in the liver.

The paper identifies antigenic cancer persister cells that survive direct T cell attack by leveraging apoptosis to avoid inflammatory death and acquiring mutations for immune resistance.

This study shows that aged livers have heightened interferon signaling that suppresses cancer but also has harmful effects, leading to a 'precarious balance' in tumor development.
