WebOct 5, 1998 · Analysis of intracellular cytokine production at the single cell level demonstrated that ADP-ribosylation of Rho inhibited beta1 integrin/ CD3 and CD28/CD3 costimulation of IL-2 production within 6 h of activation. Strikingly, IL-2 production induced by PMA and ionomycin was unaffected by C3 treatment. WebCD3ζ has two important functions: (1) assembly of the TCR-CD3 complex in the ER/Golgi and transport to the cell surface, as a TCR-CD3 complex lacking CD3ζ is mostly subjected to lysosomal degradation, (2) signaling, as the TCRαβ or TCRγδ dimer itself lacks the signaling motifs and relies on the CD3ε, CD3γ, CD3δ, and CD3ζ components for …
