WitrynaImmunological Synapse Formation. Activated T cells rely on the ability of their T cell receptor (TCR) to recognize antigen on the surface of target cells. In the case of CD4 + T cells, recognition occurs via antigen-bound MHC II, while CD8 + CTLs recognize antigen displayed by MHC I. WitrynaAssessing immune synapse formation can provide insights into priming by antigen presenting cells. iTreg and CD4 Th cell differentiation are T cell assays developed to observe activation and polarization of T cell subsets. Treg assays assess the ability of a therapeutic to inhibit Treg function, a major readout is the proliferation of the ...
