WebCytotoxic T lymphocytes (CTL) kill target cells on the basis of cell-surface antigen recognition and are important in the host response to tumors, transplants, and viruses. This unit presents several protocols for generating and measuring CTL activity. The first describes generating CTL against some of the most commonly used target antigens. WebOverall, our results indicate that melanoma cells have hijacked plasma membrane wound-healing processes, that are lysosome exocytosis-based and Ca 2 +-dependent (Cheng …
WebCytotoxic T lymphocytes (CTLs) with a CD8 (+) phenotype have the potential to recognize and attack major histocompatibility complex (MHC) class I-expressing brain cells. Most brain cells, including neurons, can be stimulated to present peptides to CD8 (+) CTLs by MHC class I molecules, and are susceptible to CTL-mediated cytotoxicity in culture.
WebAntibody-dependent cellular cytotoxicity (ADCC), also referred to as antibody-dependent cell-mediated cytotoxicity, is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies.
