Immunology

Question 1

Produced by plasma cells via B-cells

Answer 1

Antibodies

Question 1

Cytotoxic T-cells

Answer 1

Identify viral infected cells for destruction

Question 1

Lupus

Answer 1

AB - Antigen complexes clog the filtering organs

Question 2

Contain MHC that acts to ‘present’ the invader antigen to the killer and helper T-cells

Answer 2

APC’s Antigen presenting cells

Question 3

AB class that is activated as first defense and binds complement activators

Answer 3

IgM

Question 4

Often follow infection d/t supercharged immune system response

Answer 4

Autoimmune

Question 6

Arise from stem cells, give rise to plasma and memory cells

Answer 6

B-cells

Question 6

Prevents attacking self cells, B-cells and T-cells both bind to confirm antigen is foreign

Answer 6

MHC

Question 7

Activates B cells and killer T-cells Directs actions of proteins and cytokines

Answer 7

Helper T-cells

Question 8

Tag foreign antigens for destruction

Answer 8

Antibodies

Question 9

Rash, inflammation, kidney damage d/t IgG attacking self antigens - affects primarily women

Answer 9

Lupus

Question 10

Kiss of death

Answer 10

Process by which a pathogen is marked for death Opsonization

Question 11

Allergic response- parasite defense Made after first exposure

Answer 11

IgE

Question 11

Cell surface protein that presents antigen to T-cells as foreign

Answer 11

MHC Major histocompatibility complex

Question 11

IgE AB d/t antigen Mast cells degranulate releasing histamine

Answer 11

Allergies Hay fever, asthma etc

Question 12

Myasthenia gravis

Answer 12

Poliovirus protein is similar to Ach receptor causing immune response

Question 12

Macrophages stimulate TNF that damages joint spaces

Answer 12

RA

Question 14

Neutralizes viruses Life span of 3 weeks

Answer 14

IgG

Question 15

RA

Answer 15

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

Question 16

Alpha, beta, gamma receptors

Answer 16

T-cells Recognize the antigen

Question 18

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

Answer 18

IgA

Question 19

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

Answer 19

Autoimmune

Question 20

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

Answer 20

IDDM

Question 22

Function of AB binding

Answer 22

Prevent virus from entering cells

Question 24

The central function of adaptive immunity

Answer 24

Antigen presentation

Question 25

AB class that brings killer cells to the target Good opsonizer

Answer 25

IgG

Question 26

Initial infection attack - complement activator! Life span 1 day

Answer 26

IgM

Question 28

Guards mucosal cells Abundant

Answer 28

IgA

Question 29

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

Answer 29

Myasthenia gravis

Question 30

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

Answer 30

IgE

Question 31

Function of B-cells

Answer 31

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