Superresolution imaging demonstrates bispecific antibodies improve cytotoxic effects in T cells, indicating complex membrane contacts.

The study aims to uncover the biophysical mechanisms by which bispecific antibodies facilitate T cell-tumor cell contact.
T cells were isolated and labeled with membrane proteins using NHS-ester chemistry.
T cells were co-cultured with A20 lymphoma cells with and without bispecific antibodies.
T cell interactions with surfaces and tumor cells were imaged using fluorescence and superresolution techniques.
Bispecific antibodies enhanced T cell spreading and activation upon contact with cancer cell surfaces.
Superresolution imaging showed T cells forming specialized synapses with A20 cells in the presence of bispecific antibodies.
T cells conformed to and interacted more closely with tumor cell membranes, indicating complex contact dynamics.
