Q

what is the function of the innate immune system releasing inflammatory mediators?

A

alerts body that there has been a breach, causing macrophages and other immune cells to come to the site of the breach

Q

what is the complement pathway?

A

a series of proteins that are activated in a cascade amining to quickly activate an imune response and neutralize pathogens

Q

what are the 4 main functions of the compliment pathway?

A
  1. chemotoxis (recruiting macrophages and other immune cells)
  2. lysis of micorbe cell membranes
  3. target microbes for phagocytosis (opsonization)
  4. amplify antibody response to pathogen

Q

how do the complement proteins opsonize microbes?

Q

antibodies can bind to a specific protein sequence called ____

A

an antigen

20
Q

describe the function of macrophages in innate immune function

A

engulf pathogens and break them down in lysosomes and present antigens to adaptive immune system

21
Q

how do macrophages recognize pathogens?

A

based on general features (LPS etc.) and due to opsonization by complement proteins, but its not specific and they do not have memory

22
Q

an antigen presenting cell tells T cells what to ____ and B cells what to ___

A

target; remember

23
Q

___- cells are the primary mediators of the cell-mediated immune responses

A

T

24
Q

what activates helper T cells?

A

connection with an antigen presenting cell

25
Q

how do helper T cells alert other T cells of an infection?

A

by secreting cytokines

26
Q

what are 3 types of T cells?

A

helper, natural killer, and cytotoxic

27
Q

the cytokines released by helper T cells also increase the activity of ____

A

macrophages

28
Q

helper T cells also communicate with B cells to facilitate the production of ___ cells

A

memory

29
Q

how are memory cells made?

A

once alerted of the antigen by helper T cells, B cells will make antibodies against it so they can be used to fight the infection in the future

30
Q

antibodies are also called ____

A

immunoglobulins

31
Q

what types of cytokines do helper T cells produce?

A

IL 1 and IL2 etc

32
Q

antibodies have very specific binding regions that recognize a small portion of the ____ on an antigen

A

peptide sequence

33
Q

the specific peptide sequence of antigens that bind to antibodies is called the ___

A

epitope

34
Q

where can antibodies be found?

A

on the surface of B cells or circulating in plasma

35
Q

how do vaccines work?

A

intentionally injected with antigens so our body will build antibodies against it

36
Q

what is the role of immune cells producing antibodies to our own cellular proteins?

A

allows them to know of something has gone wrong with a cell and if it needs to be destroyed

37
Q

which cells are responsible for “Humoral immunity”?

A

B cells

38
Q

what happens in an autoimmune disorder?

A

immune system recognizes self-antigens as foreign and attacks healthy cells

39
Q

what is Grave’s disease?

A

autoimmune disease (hyperthyroidism)

40
Q

what causes Grave’s disease?

A

immune system produces antibodies that stimulate the production and secretion of thyroid hormones

41
Q

what is psoriasis?

A

autoimmune disorder that causes high proliferation of skin cells, resulting in additional layersand plaques

42
Q

what type of allergic reaction is the most common?

A

type 1 hypersensitivity reaction

43
Q

type 1 hypersensitivity reaction involves ____ antibodies

A

IgE

44
Q

type 1 hypersensitivity reactions cause the release of inflammatory mediators from ___ cells

A

mast

45
Q

igE antibodies bind to antigens on ____ cells

A

mast
