Study Notes
Immune Response Types
- Humoral immune response provides protection to the host by secreting antibodies.
- Cell-Mediated Immune response (CMI) is mediated by T cells.
Cell-Mediated Immune Response (CMI)
- T cells are stimulated by cytokines released from other T cells to produce antibodies.
- Cytotoxic T Cells (CTLLs) recognize and kill infected cells or produce cytokines that activate other immune cells.
- NK cells recognize and kill infected cells or tumor cells, playing a crucial role in the early defense against infection.
Interdependence of Immune Responses
- Antibody-Mediated Immune response (AMI) and Cell-Mediated Immune response (CMI) are interconnected and require interaction to provide effective protection.
- Helper T Cells (TH1 & TH2) facilitate the interaction between AMI and CMI by coordinating the immune response.
Antibody-Mediated Immune Response (AMI)
- AMI provides protection to the host by producing antibodies that recognize and bind to specific antigens.
Cell-Mediated Immune Response (CMI) Pathways
- Cytosolic Pathway involves the detection of viral antigens within the cytosol, leading to the activation of CTLs.
- Endocytic Pathway involves the detection of viral antigens within the endosomes, leading to the activation of CTLs and the presentation of antigens to T cells.
