Study Notes
Innate Immunity
- Involved cells: Neutrophils, macrophages, dendritic cells, and natural killer cells
- Main role: First line of defense against pathogens, recognizing and eliminating them
Adaptive Immunity
- Main role: Specific recognition and elimination of pathogens, with memory and specificity
- Involved cells: T cells and B cells
- Antigen receptors: Recognize specific antigens
Antigen Presentation
- Lineage of cells responsible: Dendritic cells and macrophages
- Main role: Processing and presenting antigens to T cells
Cytokines and Chemokines
- Cytokines: Signaling molecules that coordinate immune responses
- Main role: Interactions between immune cells, recruiting immune cells to sites of infection
- Chemokines: Specialized cytokines that attract immune cells to sites of infection
- Main role: Directing immune cell migration
T Cells
- CD4 T cells: Assist in activating B cells and other immune cells
- CD8 T cells: Directly kill infected cells
- T cell receptors: Recognize specific antigens
- Produced through: Somatic recombination and gene rearrangement
B Cells
- Main function: Producing antibodies
- Antibody molecule: Consists of variable and constant regions
- Variable region: Recognizes specific antigens
- Constant region: Interacts with cells or other immune elements
- Antigen binding site: Also known as the paratope
Immune System
