Flow Chart Of Cell Mediated Immunity

Cell mediated immunity is an important aspect of the immune system that involves the activation of T cells to recognize and destroy infected cells and pathogens. This process is crucial for the body’s defense against viruses, intracellular bacteria, and other pathogens that hide inside cells.

Understanding the flow chart of cell mediated immunity can help in visualizing the complex interactions between different immune cells and molecules involved in this process.

Key Players in Cell Mediated Immunity

The flow chart of cell mediated immunity begins with the presentation of antigens by antigen-presenting cells (APCs) such as dendritic cells. These APCs process and present antigens to T cells, specifically CD4+ helper T cells and CD8+ cytotoxic T cells.

Helper T cells release cytokines that stimulate the activation and proliferation of cytotoxic T cells, which then recognize and kill infected cells. This process is essential for eliminating intracellular pathogens and preventing the spread of infection.

Effector Mechanisms in Cell Mediated Immunity

Once activated, cytotoxic T cells release perforin and granzymes to induce apoptosis in infected cells. This process ensures the targeted destruction of infected cells while minimizing damage to healthy tissues.

In addition to cytotoxic T cells, natural killer (NK) cells also play a role in cell mediated immunity by recognizing and killing infected cells in a non-specific manner. This provides an additional layer of defense against intracellular pathogens.

Overall, the flow chart of cell mediated immunity highlights the coordinated efforts of various immune cells to eliminate infected cells and pathogens. Understanding this process is crucial for developing effective strategies to boost immune responses and combat infectious diseases.
