Adaptive Immunity (18) Flashcards
the body’s ability to recognize and defend itself against distinct invaders and their products (specific)
Adaptive Immunity
5 attributes of adaptive immunity
Specificity Inducibility Clonality Unresponsiveness to self Memory
2 main lymphocytes involved in Adaptive Immunity
B lymphocytes (B cells)
mature in the bone marrow
T lymphocytes (t cells)
mature in the thymus
2 types of Adaptive Immune Response
Cell- mediated immune responses
Humoral immune responses (Antibody)
Primary lymphoid organs
Red bone Marrow
Thymus
Secondary lymphoid organs
Lymph nodes
Spleen
Tonsils
Mucosa-associated lymphoid tissue (MALT)
2 largest chains of antibodies
Heavy Chain (Bottom set) also known as the Constant Region and FC region for fragment of crystallization
2 smaller chains of antibodies
Light chains (top)
2 “arms” or Y shapes antibody molecule
Fab region “ fragment of antigen binding” (top)
also known as Variable Region
First antibody produced
IgM
Most common and longest lasting antibody
IgG
Associated with body secretions
IgA
Involved in response to parasitic infections and allergies
IgE
Exact function is poorly understood
IgD
5 Functions of Antibodies
Neutralization Opsonization Oxidation Agglutination Antibody-dependent cellular cytotoxicity
