Novel mechanism of signaling by CD28.

abstract：:The inflammatory response plays an important role during the induction of several neonatal diseases. Previous studies have shown that during newborn infections, the natural imbalance between pro- and anti-inflammatory responses shifts toward the production of pro-inflammatory cytokines. In this study, we employed an a...
