CD20 × CD3 bispecific antibodies bind to both CD20 on malignant B cells and CD3 on T cells, bringing them into close proximity, which triggers T cell-mediated killing of the targeted B cells.

In addition, the association of CD3 with the TCR–peptide–MHC complex transmits the activation signal to intracellular signalling molecules to initiate a signalling cascade in the T cell.

Notably, IFT20 clusters with TCRs at the immune synapse and associates with the ζ- and ɛ-chains of CD3 in response to TCR engagement. TCR–CD3 complex assembly is initiated in the endoplasmic ...
