Acquired Immunity
|
Immunity developed somewhere in lifetime
Not preexisting |
|
|
Adaptive Immunity
|
Tailor made immunities
|
|
|
Specific Devensive Response
|
When host is invaded by foreign substances
|
|
|
2 Components of the Immune System
|
Humoral Immune System
Cell Mediated Immune System |
|
|
Humoral Immune System
|
Ab molecules dissolved in blood plasma & will be found in blood & lymph fluid
|
|
|
B Cells
AKA Lymphocytes |
1. Eventually produce Ab Molecules
2. Stimulated by Ag becoming plasma cells 3. Produce/Secrete Ab 4. Attack Ag |
|
|
Antigen
Ag |
Anything that is foreign to the body & illicit an immune response
|
|
|
Examples of Ag
|
Cancer, Bacteria, Viruses, Fungi, Dust/Pollen, Transplanted Tissue
|
|
|
Cell Mediated Immune System
CMI |
Tcells don't produce Ab's, but have Ab like receptors on surface
|
|
|
Acquired/adaptive Immunity
|
Natural or Artificial
Natural or Passive |
|
|
Naturally Acquired Active Immunity
|
Immunity developed in everyday life activity upon natural exposure to Ag.
|
|
|
Naturally acquired active immunity PRODUCE...
|
Ab molicules to specifically attack that specific Ag
& Sensitized Tcells (tailor made to attack specific Ag) |
|
|
Examples Lifelong Immunities
|
Measles
Chicken Pox Yellow Fever |
|
|
Longterm Immunity
|
Diphtheria
|
|
|
No Effective Immunity
|
Colds & Gonorrhea
|
|
|
Naturally Acquired Passive Immunity
|
Occurs from immunized donor to non immunized recipient
|
|
|
Placenta Transfer
|
Temp immunity from mom to unborn fetus
|
|
|
Colostrum
|
1st Breast Milk produced immediately after birth & 24hrs post birth
|
|
|
Colostrum Component
|
Most especially IgA
|
|
|
Importance of Immediate Colostrum
|
absorbtion throug porosity - every hr after birth GI track becomes less porous.
|
|
|
Vaccine Interference
Early Vaccination |
Passed Abs from mom can interfere with vaccine & render it useless
|
|
|
Artificially Acquired Active Immunity
|
Immunity developed upon vaccination
Not naturally exposed but exposed by injection |
|
|
Artificially Acquired Passive Immunity
|
Occurs when injection of Ab obtained from outside source
|
|
|
Example of Artificially Acquired Passive Immunity
|
Snake bite Venom - Venom works faster & stronger than Human Immune System.
|
|
|
Manufacturing Snake Bite Venum
|
Horse injected with venum
Immune system is stimulated Blood is harvested & Centrifuged Serum/Plasma removed & becomes venum |
|
|
Serum
|
Includes portions of Alpha, Beta, Gamma & Albumin
|
|
|
Gamma
|
Vast majorities of ...
|
|
|
Electrophoresis
|
Seperates molecules based on size & electrical charge
|
