Antibody-dependent cellular cytotoxicity by allosensitized human T cells.

Antibody-dependent cellular cytotoxicity by allosensitized human T cells

Peripheral human T cells, isolated by sheep erythrocyte-rosette formation and density centrifugation, were highly cytotoxic to both Ab-coated autologous lymphocytes and antibody (Ab)-coated chicken erythrocytes when stimulated in mixed lymphocyte culture, but were not lytic when freshly purified, or when unstimulated in 6-day culture. Allosensitized T cells were shown to effect this activity by...

Antibody-dependent cellular cytotoxicity toward neuroblastoma enhanced by activated invariant natural killer T cells.

Anti-ganglioside GD2 antibodies mainly work through antibody-dependent cellular cytotoxicity (ADCC) and have demonstrated clinical benefit for children with neuroblastoma. However, high-risk neuroblastoma still has a high recurrence rate. For further improvement in patient outcomes, ways to maximize the cytotoxic effects of anti-GD2 therapies with minimal toxicity are required. Activated invari...

Antibody-dependent cellular cytotoxicity (ADCC) is mediated by genetically modified antigen-specific human T lymphocytes.

In the context of transplantation, donor and virus-specific T-lymphocyte infusions have demonstrated the dramatic potential of T cells as immune effectors. Unfortunately, most attempts to exploit the T-cell immune system against nonviral malignancies in the syngeneic setting have been disappointing. In contrast, treatments based on monoclonal antibodies (Abs) have been clinically successful and...

Antibody-Dependent Cellular Cytotoxicity of Within Peripheral Blood Mononuclear Cells,

Antibody-Dependent Cellular Cytotoxicity against Reactivated HIV-1-Infected Cells.

UNLABELLED Lifelong antiretroviral therapy (ART) for HIV-1 does not diminish the established latent reservoir. A possible cure approach is to reactivate the quiescent genome from latency and utilize immune responses to eliminate cells harboring reactivated HIV-1. It is not known whether antibodies within HIV-1-infected individuals can recognize and eliminate cells reactivated from latency throu...
