- Feature
- Cellular Immune Response
- Humoral Immune Response
- Main Cells Involved
- T lymphocytes (CD4+, CD8+)
- B lymphocytes (plasma cells)
- Primary Function
- Elimination of infected or abnormal cells
- Neutralization of extracellular pathogens
- Target Pathogens
- Intracellular (e.g., viruses, some bacteria)
- Extracellular (e.g., bacteria, toxins)
- Mechanism of Action
- Direct cell killing and cytokine-mediated regulation
- Antibody production for neutralizing and marking for destruction
- Key Effector Molecules
- Cytokines, perforin, granzymes
- Antibodies (immunoglobulins)
- Antigen Recognition
- Via MHC-presented antigens
- Direct recognition of free antigens
- Memory Formation
- Memory T cells
