Web24 aug. 2024 · Exposure of bystander cells to BiTE ®-activated T cells induced the expression of the death receptor FAS as well as ICAM-1, a molecule involved in stabilizing cytolytic T cell synapses. ICAM-1 and FAS upregulation on bystander cells was also observed following treatment with recombinant IFNγ and TNFα. WebBystander T-cell activation is defined as the activation of a T cell to produce phenotypic or functional changes through a mechanism which is independent of specific T-cell receptor (TCR) stimulation. This incorporates activation through soluble factors or membrane-bound molecules that bind to receptors other than the TCR.
