Programmed death-1 (PD-1) is a cell surface receptor that functions as a T cell checkpoint and plays a central role in regulating T cell collapse. The binding of PD-1 to its ligand programmed death-ligand 1 (PD-L1) activates downstream signaling pathways and inhibits T cell activation in...

In vitro T-cell activation and flow cytometry PBMC, and cells from NT and tumor were thawed the day before staining and cultured overnight in RPMI 1640 supplemented with 10% HS and 12 U/ml rIL-2. The day after, 2–3 × 103 unstimulated cells were stained with diverse combinations ...
细胞质信号序列可包含信号基序(signalingmotif),这些基序被称为免疫受体酪氨酸活化基序(itam,immunoreceptortyrosine-basedactivationmotif)。itam是定义明确的信号基序,发现于作为syk/zap70类酪氨酸激酶的结合位点的多种受体的胞质区尾段。作为非限制性实例,itam的实例可包括衍生自tcrδ、fcrγ、fcrβ、fcrε、cd3γ、...
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 ...
