Q

ANTIGEN

A

-SUBSTANCE THAT CAN ELICIT IMMUNE RESPONSE

-CAN MARK CELLS AS SELF OR NON-SELF

-CAN STIMULATE B LYMPHOCYTES AND CYTOTOXIC RESPONSES

AUTOANTIGENS-ON BODY’S OWN CELLS/ALL OTHERS ARE FOREIGN

INFLAMMATION HAPPENS WHEN NEUTROPHILS, MONOCYTES AND MACROPHAGES ENCOUNTER ANTIGEN

Q

HOW DO IMMUNIZATIONS WORK

A

BODY IS GIVEN (IM, NASAL, ETC…) ANTIGEN (LIVE OR NOT)

OFTEN A PIECE OF THE VIRUS/BACTERIAL INFO IS IN THE IMMUNIZATION

BODY RESPONDS FIRST WITH NON-SPECIFIC IMMUNITY, THEN BUILDS AN ARMY FOR THE NEXT TIME IT SEES THIS PARTICULAR ANTIGEN

A

THE PRODUCTION OF BLOOD CELLS AND PLATELETS, WHICH OCCURS IN THE BONE MARROW.

34
Q

What is an ANTIGEN

A

Can be a foreign agent triggering an immune response.

Can be distinguishing self from non-self on cells

35
Q

HYPERSENSITIVITY REACTIONS

A

Type 1: Allergy, High IgE, Typically Development of Urticaria/Hives, Watery/Inflamed Eyes, nasal/bronchial congestion, bronchospasm, anaphylaxis

Type 2: Ex. Erythroblastosis fetalis (hemolytic disease in newborn); Cytotoxic destruction of cells secondary to the activation of complement, antibodies, or phagocytosis.

Type 3: formation of immune complexes which deposit in blood vessels or tissues throughout the body

4: Ex. Mantoux, contact dermatitis, poison ivy

36
Q

type I hypersensitivity

A

Immunoglobulin E–mediated type of hypersensitivity in which an allergen activates T cells that then bind to mast cells. Repeated exposure to relatively large doses of the allergen is usually necessary to cause this response.

37
Q

type II hypersensitivity

A

Tissue-specific type of hypersensitivity that generally involves the destruction of a target cell by an antibody-directed cell-surface antigen. Immunoglobulin G or M reacts with an antigen on the cell, activating the complement system. The effects of type II reactions include cell lysis and phagocytosis.

38
Q

type III hypersensitivity

A

immune complex–mediated type of hypersensitivity in which circulating antigen–antibody complexes accumulate and are deposited in the tissue. This accumulation triggers the complement system, causing local inflammation and increased vascular permeability, so more complexes accumulate.

39
Q

type IV hypersensitivity

A

Cell-mediated type of hypersensitivity that involves a delayed processing of the antigen by the macrophages. Once processed, the antigen is presented to the T cells, resulting in the release of lymphokines that cause inflammation and antigen destruction.
