近日,复旦大学代谢与整合生理学研究院刘军力研究员与上海交通大学医学院附属第六人民医院陈素贞副研究员联合团队在Nature Communications 发表题为 Myristoylated Eepd1 Enhances Lipolysis and Thermogenesis through PKA Activation to Combat ...
After TCR engagement, T cells induce expression of CD25, which forms the IL2 high affinity receptor complex, concurrently with PD1, which plays a down-regulatory role in activation. Cessation of TCR stimulation leads to eventual contraction of T cell responses. Chimeric antigen receptor (CAR) T ...
T-cell activation is generally self-limited as activated T cells express receptors such as PD-1 (also known as PDCD-1) that mediate inhibitory signals from the APC. PD-1 can bind two different but related ligands, PDL-1 and PDL-2. Upon binding to either ...
