IMMUNE Flashcards
Henry comes back from his hike, poison ivy
TYPE 4
In a routine exam, some blood is taken and analyzed, high IgM and low IgG
was recently affected w MUMPS
T cell activation requires
antigen binding and co-stimulation
When the body mistakenly targets…
AUTOIMMUNE DISEASE
Which would be recognized by T cell receptor
- peptide from protein
What cell type kills cells infected by virus
- cytotoxic T cells
Exogenous antigens for example bacterial components
- enter from the outside, MHC2
Which is not an autoimmune disease
- AIDS (acquired immunodeficiency syndrome)
Regulatory T cells
- may function in preventing autoimmune reactions
Cells that leave the thymus w the ability to class Il molecules will develop into
- CD4 HELPER T CELLS
Strep
- may need a heart transplant???
Which of the following would not occur during an allergic reaction
- increase in IgG
T helper cells
- function in adaptive immune system activation
stress hormone
corticosteroid
A crime scene investigator … what was the fluid?
- saliva?? (if it mentions IgA)
What occurs in the thymus?
TCR (T cell receptor)
Natural killer cells secrete
- cytokines
Cells provide for rapid secondary response
- memory cells
T cells are differentiated into 2 groups…
- CD4 and CD8 = helper cells
Another term for anitbody
- Immunoglobulin
HIV selectively affects
- helper T cells
Alergens differ from antigens because
- they produce an abnormally large immune response to what is otherwise a “harmless” particle
When an antigen is bound to a class II MHC protein it can activate
- helper T cell
What exists when an immune system does not respond to a particular antigen
TOLERANCE
