Aging-induced hepatocyte CD44 drives IL6/STAT3 signaling that associates with impaired function of neighboring T cells

Liver cancer incidences increase dramatically beyond 55 years of age, suggesting that age-associated changes contribute critically to tumor initiation. However, the mechanisms linking liver aging and cancer initiation remain incompletely defined. This study investigated the role of CD44, a marker of liver tumor-ini...

Sulfotransferase signaling sustains fibroblast identity and antagonizes therapeutic cardiac reprogramming

It is shown that the sulfotransferase CHST7 stabilizes fibroblast fate via CD44/JUNB signalling, and that its inhibition enhances cardiac reprogramming and improves heart repair, and defines a sulfotransferase-dependent barrier to cell fate conversion with therapeutic implications for heart regeneration.
