Study Notes
T Lymphocytes Overview
- T lymphocytes are described as a type of immune cell that plays a central role in cell-mediated immunity.
Antigen Presentation
- T lymphocytes respond to MHC-restricted antigen presentation, meaning they recognize and respond to antigens displayed on the surface of antigen-presenting cells.
T Lymphocyte Subtypes
- α:ß T lymphocytes and γ:δ T lymphocytes are two subtypes of T lymphocytes, differing in their T cell receptors and functions.
Thymus and T Lymphocyte Development
- The thymus is essential for the development and maturation of α:ß T lymphocytes, where they undergo positive and negative selection.
Tolerance and Selection
- Positive selection ensures that T cells recognize self-MHC molecules, while negative selection eliminates autoreactive T cells, promoting central tolerance.
- Immature T cells that undergo negative selection are eliminated, preventing autoimmune responses.
Importance of T Cell Development
- Understanding T cell early development is crucial, as defects in this process can lead to immunodeficiencies or autoimmune disorders.
MHC-Restriction and TCR Engagement
- Learning objectives related to MHC-restriction and T cell receptor (TCR) engagement include understanding the mechanisms of antigen presentation and TCR-ligand interaction.
Innate Immunity and Cytokines
- The primary focus of the section on innate immunity, cytokines, and inflammation is to understand the first line of defense against pathogens and the roles of cytokines in modulating the immune response.
Antigen-Presenting Cells
- Professional antigen-presenting cells, such as dendritic cells, process and present antigens to T lymphocytes, initiating an adaptive immune response.
