Abstract:
Recent studies suggest that tissue resident Vδ1-T cells may downregulate immune responses in human beings. However, the function of peripheral blood Vδ1-T cells and their mechanisms of action remain largely unknown because of their limited numbers and the difficulties encountered in expanding these cells. In this study, we provide direct evidence demonstrating that peripheral human Vδ1-T cells can abrogate adaptive immune responses by direct killing of autologous dendritic cells through a perforin-mediated pathway. These findings advance our basic understanding of this unique T-cell subset.

Cytotoxic T Cells-mediated Immune Response
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
