immunodeficiencies Flashcards
defect in BTK ( no b cell maturation
x-linked Bruton agammaglobulinemia
defect in b cell differentiation
Common variable immunodeficiency
deficient in TH 17 cells because of a STAT3 mutation ( impaired recruitment of neutrophils to infection)
autosomal dominant hyper IgE syndrome “job syndrome”
t cell dysfcuntion
chronic mucocutaneous candidiasis
defective IL-2R gamma chain and adenosine deaminase
SCID
defective ATM gene failure to repair DNA double stranded breaks
ataxia-telangiectasia
defective CD40L on TH cells so there is a class switching problem (x linked recessive)
hyper IgM syndrome
mutation in WAS gene so that t cells are unable to recognize actin cytoskeleton ( x linked recessive)
Wiskott-Aldrich Syndrome
defect in LFA-1 intern (CD18) protein on phagocytes, impaired migration and chemotaxis ( AR)
Leukocyte Adhesion Deficiency type 1
defect in lysosomal trafficking regulator gene (LYST) causing microtubule dysfunction in phagolysosome-lysosome fusion (AR)
chediak-higashi syndrome
defect in NADPH oxidase causing a decrease in ROS
CGD
