✨Bring on the good fortune✨
This #PhallusThursday we celebrate with this tuff stele from Pompeii that depicts a large phallus inside a temple. If you ever wondered if the Romans attributed divine power to the phallus, wonder no more!

Targeting ECM-producing cells with CAR-T therapy alleviates fibrosis in chronic kidney disease
Targeting ECM-producing cells with CAR-T therapy alleviates fibrosis in chronic kidney disease
Zhao et al. identify PDGFRβ as a common surface antigen for the major ECM-producing cells including fibroblasts, pericytes, and myofibroblasts in the kidney. They further demonstrate that PDGFRβ CAR-T cells significantly alleviate fibrosis-associated pathologies in multiple CKD models, evoking an integrated therapeutic strategy for CKD and its cardiovascular complications.
