255 immunity

Active natural immunity =

pt acquired disease and now has immunity
active artificial immunity =

immunization
Passive natural immunity =

acquired immunity through mother
Passive artificial =
- injection of serum from immune human
- like Hep B
where do T lymphocytes mature

thymus gland
B lymphocytes develop where

bone marrow
t cells are apart of what immunity

cell immunity
humoral immunity think about

antigen antibodies
plasma cells produce

antibodies (immunoglobulins)
B lymphocytes differentiate into

plasma cells when activated
viruses are killed by

T lymphocytes
are cancer cells attacked by humoral or cell mediated immunity
- cell mediated
- T cells
CD8 cells are

cytotoxic cells
CD4 cells are
- T helper cells
- regulate cell-mediated immunity and the humoral antibody response
what elevates the C - reactive protein

complement system
Natural killer cells are
- involved in cell-mediated immunity
- recognize and kill virus-infected cells, tumor cells, and transplanted grafts
what do cytokines do

they sound the alarm

Comparison of Humoral and Cell-Mediated Immunity
	Humoral	Cellular
Cells involved	B lymphocytes	• T lymphocytes • Macrophages
Products	Antibodies	• Sensitized T cells • Cytokines
Memory cells	Present	Present

Comparison of Humoral and Cell-Mediated Immunity
	Humoral	Cellular
Protection	•Bacteria •Viruses (extracellular) •Respiratory pathogens •Gastrointestinal pathogens	•Fungus •Viruses (intracellular) •Chronic infectious agents •Tumor cells

Comparison of Humoral and Cell-Mediated Immunity
	Humoral	Cellular
Examples	•Anaphylactic shock •Atopic diseases •Transfusion reactions •Bacterial infections	•Tuberculosis •Fungal infections •Contact dermatitis •Graft rejection •Destruction of cancer cells

primary immune response is evident when

4 - 8 days after initial exposure to antigen
what is the largest of the immunoglobulin

IgM
IgM reponsible for what

primary immune response
if someone has a lot of Igm it means

they have acute infections
IgG =

largest component of total immune globulins
elevated IgG shows

had a past infection
what immunoglobulin is given to give someone passive acquired immunity

IgG
what Immunoglobulin passes the placental border

IgG
which Immunoglobulin is found inbody secretions
- IgA
- which protects body surfaces
IgE is important in

allergic responses
primary immunoglobulin of primary response =

IgM (your miserable)
immunoglobulin of secondary immune response =

IgG
cell mediated immunity response initiated through

specific antigen recognition by T cells
Activated T cells produce

cytokines
cells that are involved in cell-mediated immunity =
- T lymphocytes
- Macrophages
- NK cells
what are some important roles of the cell mediated immunity =
- viruses
- mycobacterium
- fungal infections
- rejected transplant tissue
- hypersensitivity reactions
what are the effects of the aging on the immune system
- shrinking thymus
- decreased numbers of T cells
- lower immunoglobulin levels
