What would happen if a thymocyte that failed the negative selection test was not destroyed and instead entered the blood to circulate as a T-lymphocyte. Concept introduction: The T lymphocytes initiate cell-mediated immunity in which a number of immune cells including phagocytes, helper T cells, cytotoxic T cells, and other immune cells get activated and together fight against the invading pathogen. T-lymphocytes that survive both positive and negative selections can bind a major histocompatibility complex (MHC) molecule and recognize the foreign antigen.
