Term
HLA DR7 is associated with...
Definition
steroid responsive nephrotic syndrome
Term
What cytokines enhance the ability of natural killer cells?
Definition
IL-12, IFN beta and IFN alpha
Term
What is the costimulatory signal for CD4 cells?
Definition
B 7 on antigen presenting cell binds with CD 28 on CD4 cell
Term
What is signal 2 for activating cytotoxic T cells?
Definition
IL2 from Th cell activates Tc cell to kill virus infected cell
Term
What are the necessary signals for B cell activation and class switching?
Definition
B cell presents antigen on MHC II and it is recognized by TCR of TH2 cell; TH2 cell then releases IL-4, 5, and 6= signal one; then CD40 receptor on B cell binds CD 40L on Th cell= signal two; costimulatory signal= interaction between B7 on B cell and CD 28 on T cell
Term
What CD markers are expressed by Tregs?
Definition
CD 3, CD4, CD25
Term
What cytokines are produced by Treg cells?
Definition
IL-10 and TGF-beta
Term
Name the receptors found on macrophages?
Definition
CD 14, CD 40, MHC II, B7, Fc and C3b receptors to enhance phagocytosis
Term
How does endotoxin/lipopolysaccharide stimulate the immune system?
Definition
binds to macrophages CD14 receptor (Th cells are not involved)
Term
What bacteria has two flagellar variants?
Definition
salmonella
Term
What parasite exhibits programmed antigen variation?
Definition
trypanosomes
Term
What type of hypersensitivity is rheumatic fever?
Definition
type II
Term
What type of hypersensitivity is pernicious anemia?
Definition
type II
Term
What type of hypersensitivity causes the symptoms of SLE?
Definition
type III
Term
What type of hypersensitivity causes rheumatoid arthritis?
Definition
type III
Term
What type of hypersensitivity is associated with polyarteritis nodosum?
Definition
type III
Term
What type of hypersensitivity is associated with hypersensitivity pneumonitis?
Definition

Definition
type IV
Term
MS and guillan barre are both examples of what type of hypersenstivity?
Definition
type IV
Term
DM I is what type of hypersensitivity?
Definition
type IV
Term
What type of hypersenstivity is febrile, nonhemolytic transfusion reaction?
Definition
type II
Term
What is the antibody associated with scleroderma (diffuse)?
Definition
anti-Scl-70 (anti DNA topoisomerase I)
Term
What disease is associated with anti-desmoglein?
Definition
pemphigus vulgaris
Term
What is the antibody associated with polymyositis or dermatomyositis?
Definition
anti Jo-1
Term
What are the antibodies associated with Sjogren's syndrome?
Definition
anti SS-A (ro), anti SS-B (la)
Term
What is anti-U1 RNP found in?
Definition
mixed connective tissue disease
Term
What is the antibody found in type I DM?
Definition
anti-glutamate decarboxylase
Term
Having a deficiency in granulocytes will predispose you to what bacteria?
Definition
psuedomonas and staph
Term
What is the defect in hyper-IgM syndrome?
Definition
no CD 40L on T cells so B cells can't class switch
Term
What are the effects of a defect in IL-12 receptor?
Definition
decreased TH1 response so you see decreased IFN gamma on labs; leads to mycobacterial infections
Term
Chronic infections by candida albicans with no other problems is indicative of what immunodeficiency?
Definition
chronic mucocutaneous candidiasis (d/t a t cell dysfunction)
