T细胞受体(TCR)-CD 3复合物的高免疫受体酪氨酸激活基序(ITAM)多样性的生理基础和机制要求仍然不清楚。在这里,我们表明,虽然低TCR-CD 3 ITAM多样性足以参与导致细胞因子分泌的经典TCR诱导的信号传导事件,但TCR驱动的增殖需要高TCR-CD 3 ITAM多样性。这依赖于紧密的免疫突触形成,接头Vav 1与磷酸化CD 3 ITAM的相互作用,以介导Notch 1的募集和激活,并最终介导c-Myc诱导的增殖。也需要类似的机制事件来驱动响应于弱肽激动剂的增殖。因此,启动细胞因子分泌和增殖的TCR驱动的途径是可分离的,并通过磷酸化的TCR-CD 3 ITAM的多样性协调。
The physiological basis and mechanistic requirement for the high immunoreceptor tyrosine activation motifs (ITAM) multiplicity of the T cell receptor (TCR)-CD3 complex remains obscure. Here we show that while low TCR-CD3 ITAM multiplicity is sufficient to engage canonical TCR-induced signaling events that lead to cytokine secretion, high TCR-CD3 ITAM multiplicity is required for TCR-driven proliferation. This is dependent on compact immunological synapse formation, interaction of the adaptor Vav1 with phosphorylated CD3 ITAMs to mediate Notch1 recruitment and activation and ultimately c-Myc-induced proliferation. Analogous mechanistic events are also required to drive proliferation in response to weak peptide agonists. Thus, the TCR-driven pathways that initiate cytokine secretion and proliferation are separable and co-ordinated by the multiplicity of phosphorylated TCR-CD3 ITAMs.
