Immunodeficiency Flashcards
What and how do primary immunodeficiencies effect?
Immune cell development and function through gene mutations
What are the consequences of primary immunodeficiencies?
Deficient immune response leading to recurrent infections
What does T cell deficiency pre-dispose yo to?
Viral/fungal infections
How does understanding immunodeficiencies develop scientific understanding?
Of specific roles of cells
SCID
Severe combined immunodeficiency
What does SCID effect?
T cell development - no T cells, no antibodies, no memory
What mutations cause SCID?
In genes for cytokine signalling molecules meaning there are a lack of cells relying on this signal
Treatment for SCID?
Bone marrow transplant
CVID
What does it effect?
Common variable immunodeficiency
IgA production
What causes hyper IgE deficiency syndrome?
Mutation in TF regulating Th17 differentiation = Th17 deficiency
Oral manifestations of hyper IgE deficiency syndrome?
Supernumerary, ameolgenesis imperfecta
Cause of XLA?
Failure of B cell receptor signalling leading to a lack of antibodies
What causes acquire immunodeficiency?
Immunosensense (age, nutrition) drugs smoking
