Adaptive Immunity
HMI
-
Definition
Response to infection by production of antibody by plasma cells derived from B lymphocytes bind to pathogen and elimination of pathogen by phagocytic cells and molecules of the humoral immune system
-
Features of HMI
Antibodies
Definition
- Specialized glycoprotein produced from activated B cells also known as immunoglobulin
- Soluble protein & recognize antigen
Ab production
- Undergo affinity maturation
- Class switching
- Only occur in B cells
Antigen recognition
- Epitope has complementary sequence to specific Ab
BCR
- Initiate signaling cascade
- Deliver Ag for processing
-
Process of Antigen Presentation
- B cells use Ig to present specific Ag very efficiently to T cells
