Cell-mediated immune response is triggered by which kind of cells?

Explanation:
Cell-mediated immunity is driven by T lymphocytes. When antigen-presenting cells display fragments of pathogens on MHC molecules, T cells recognize these signals and become activated. Helper T cells (CD4+) coordinate the response by releasing cytokines that activate other immune cells, while cytotoxic T cells (CD8+) directly kill infected or abnormal cells presenting the antigen. This is different from the humoral (antibody-mediated) immunity, where B cells mature into plasma cells to produce antibodies. Neutrophils are part of the innate response and do not mediate the specific cell-mediated arm. So the cells that trigger this response are the T cells.
