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. WitrynaThe z-Movi is a unique instrument that measures the avidity between immune cells and their targets, enabling you to identify the most potent immunotherapeutic effector cells. ... Binding events between a T cell and its target tumor cell determine the initiation of immunological synapse formation and T cell activation. Cell–cell interactions ...

The initial interaction occurs between LFA-1 present in the p-SMAC of a T-cell, and non-specific adhesion molecules (such as ICAM-1 or ICAM-2) on a target cell. When bound to a target cell, the T-cell can extend pseudopodia and scan the surface of target cell to find a specific peptide:MHC complex.
