Study Notes
Immunity Overview
- Cell-mediated and humoral immunity can be compared and contrasted
- Central tolerance and peripheral tolerance are crucial for immune system function
Immune Response
- Primary response and secondary response can be defined and differentiated
- Antibody-antigen binding leads to protective outcomes
- The lymphatic system plays a vital role in immunity
Clonal Selection and Expansion
- The process of clonal selection and expansion can be outlined
- T-cell receptors (TCRs), MHC molecules, and CD markers are essential components
T Cell Activation
- Dendritic cells activate T cells
- Tε and Tч cells can be compared and contrasted in terms of antigen recognition
- Tε cells activate B cells
Immunoglobulins
- There are five classes of immunoglobulins that can be compared and contrasted
NK Cells
- NK cells have two distinct protective roles in the immune system
