Immunological synapse between dendritic cell and T cell

The “immune synapse between dendritic cells and T-cells” is not a single molecular target but rather a highly specialized intercellular interface comprising multiple molecules, primarily involved in antigen presentation and T cell activation. It is better described as a supramolecular structure or cell–cell contact zone rather than a canonical drug target such as a receptor or enzyme[7][9][4][1][5]. The **immunological synapse between a dendritic cell (DC) and a T-cell** is a specialized cell–cell junction that forms during antigen presentation. It enables DCs, the primary antigen-presenting cells, to efficiently present peptide–MHC complexes and deliver co-stimulatory and cytokine signals to T cells, triggering their activation, proliferation, and differentiation. The canonical structure is multifocal rather than a simple "bulls-eye," especially in DC–T cell pairs, involving dynamic reorganization of membrane proteins (such as TCR, MHC II, CD3, LFA-1, ICAM-1, CD28, CD70), cytoskeletal rearrangement, and polarized secretion of immunomodulatory factors. Though not a molecule or classical "drug target," it is a critical immunological interface exploited by immunotherapies targeting individual synaptic components[7][1][5][9][2][4].
