WebOct 5, 2024 · CD8+ T cells can be used with bispecific antibodies to direct their cytotoxicity to the desired target cells. CD8+ T cells are a good starting material for developing antigen-specific T cells. Antigen-specific cytotoxic T cells (CTL) can be used as tools for detecting antigens presented by infected cells or tumor cells. WebCD4+ T cells with cytotoxic activity (CD4 CTL) have been observed in various immune responses. These cells are characterized by their ability to secrete granzyme B and perforin and to kill the target cells in an MHC class II-restricted fashion. Although CD4 CTLs were once thought to be an in vitro artifact associated with long-term culturing, they have since …
