State
Helper T cells coordinate the adaptive response by signaling B cells and other immune cells; cytotoxic T cells directly destroy infected or abnormal cells they recognize.
Show
Helper T cell signaling boosts both B cell antibody output and cytotoxic T cell activity.
Watch for
Helper T cells coordinate but do not destroy infected cells themselves — that role belongs to cytotoxic T cells.
