T cell activation and Differentiation.

Описание: T cell activation and Differentiation.
The innate immune system consists of defenses against infection that are activated instantly as a pathogen attacks. Adaptive immunity (or acquired immunity) is a subsystem of the immune system that contains highly specialised systemic cells and processes that kill pathogens and prevent their growth in the body. The humoral immunity is the immunity that is developed by the B cells by producing antibodies. And the Cell mediated immunity is formed with the help of T cells by forming phagocytic cells.This lecture explains about the T cell activation mechanism which is one of the most importat tasks that needs to be established for the purpose of activating the immune system of cells.This type of immune response comesi into action once the macrophage or the antigen presents the cells to the t cells that help in engulfing the pathogen and degrading it. Many antigen presenting cells also break these engulfed pathogen down and showcase that to the rest of immune system with MHC molecules on surface. Innate immunity cross talks with adaptive immunity and activates the adaptive immune response with the help of interleukins and Cytokine signalling.
