Cell-Mediated Immunity: T Lymphocyte Functions

Created using ChatSlide

This lecture delves into the intricate world of T lymphocytes, key players in the human immune system. It covers foundational knowledge, including types and roles in immunity, and explores activation mechanisms involving antigen recognition and co-stimulatory signals. We examine cytotoxic T cells for their targeted responses, and helper T cells for their cytokine production and regulatory roles in immune modulation. Regulatory T cells' function in maintaining tolerance and clinical...
