Q

Myasthenia gravis

A

Poliovirus protein is similar to Ach receptor causing immune response

12
Q

Macrophages stimulate TNF that damages joint spaces

A

RA

14
Q

Neutralizes viruses Life span of 3 weeks

A

IgG

15
Q

RA

A

Autoimmune damage to joints = inflammation of cartilage protein - IgM/IgG complexes

16
Q

Alpha, beta, gamma receptors

A

T-cells Recognize the antigen

18
Q

AB class that traverses the digestive tract and collects pathogens to eliminate thru poops

A

IgA

19
Q

MHC molecules presenting peptides derived from self or B/T cells have receptors for self antigen

A

Autoimmune

20
Q

Immune cells attack beta cells of pancreas- cytotoxic T-cells attack pancreas

A

IDDM

22
Q

Function of AB binding

A

Prevent virus from entering cells

24
Q

The central function of adaptive immunity

A

Antigen presentation

25
Q

AB class that brings killer cells to the target Good opsonizer

A

IgG

26
Q

Initial infection attack - complement activator! Life span 1 day

A

IgM

28
Q

Guards mucosal cells Abundant

A

IgA

29
Q

Antibodies against self NMJ Ach receptors Ach is blocked from binding- results in weakness

A

Myasthenia gravis

30
Q

AB class that increase immune activity and whose binding to allergen causes mast cell to degranulate

A

IgE

31
Q

Function of B-cells

A
  1. Produces 1 type of AB 2. Recognizes and binds many foreign substances
