IL-21R-Targeted Nano-immunosuppressant Prevents Acute Rejection in Allogeneic Transplantation by Blocking Maturation of T Follicular Helper Cells.

During organ transplantation, immune rejection is a primary cause of graft failure. In the underlying pathophysiology of rejection, T follicular helper (Tfh) cells and interleukin-21 (IL-21) play pivotal roles. Tfh cells exacerbate the humoral immune response by promoting B cell differentiation and antibody production, which leads to damage of the transplanted tissue.

Thermosensitive gel-nano system against esophageal cancer via restoring p53 activity and boosting T-cell immunity.

In esophageal cancer (EC), clinical specimen testing has uncovered a significant increase in BTB and CNC homolog 1 (BACH1) expression and a shift towards an immunosuppressive environment, alongside a notable decrease in p53 protein expression. Therefore, therapeutic strategies focusing on BACH1 inhibition and p53 upregulation appear promising. Traditional oral treatments for EC lack precision and efficacy.
