Immunology Flashcards
Produced by plasma cells via B-cells
Antibodies
Cytotoxic T-cells
Identify viral infected cells for destruction
Lupus
AB - Antigen complexes clog the filtering organs
Contain MHC that acts to ‘present’ the invader antigen to the killer and helper T-cells
APC’s Antigen presenting cells
AB class that is activated as first defense and binds complement activators
IgM
Often follow infection d/t supercharged immune system response
Autoimmune
Arise from stem cells, give rise to plasma and memory cells
B-cells
Prevents attacking self cells, B-cells and T-cells both bind to confirm antigen is foreign
MHC
Activates B cells and killer T-cells Directs actions of proteins and cytokines
Helper T-cells
Tag foreign antigens for destruction
Antibodies
Rash, inflammation, kidney damage d/t IgG attacking self antigens - affects primarily women
Lupus
Kiss of death
Process by which a pathogen is marked for death Opsonization
Allergic response- parasite defense Made after first exposure
IgE
Cell surface protein that presents antigen to T-cells as foreign
MHC Major histocompatibility complex
IgE AB d/t antigen Mast cells degranulate releasing histamine
Allergies Hay fever, asthma etc
