Neutralizing antibodies to TNF and IFNγ block [CD4XL/CD3]-induced T-cell apoptosis.
CD4XL/CD3 treatment was performed in PBTs in the absence or presence of various concentrations of anti-IFNγ antibody (open circles) or anti-TNFα antibody (closed circles). Data obtained from the simultaneous addition of anti-IFNγ antibody (1.0 μg/mL) and anti-TNFα antibody (3.0 μg/mL) are indicated as open squares. Apoptosis was determined by annexin V labeling. Data represent 2 independent experiments.
