What are the 3 responses to immune process
|
1. Inflammation
2. Antibody-mediated immunity (humoral immunity) or AMI 3. Cell mediated immunity or CMI |
|
|
______ can occur without infection
|
Inflammation
|
|
|
Cardinal signs of inflammation
|
1. Warmth
2. Redness 3. Swelling 4. Pain 5. Decreased function |
|
|
What are the cell types involved in inflammation (all leukocytes)
|
Neutrophils
Macrophages/ Monocytes Eosinophils Basophiles |
|
|
Account for about 67% of WBC's
Takes about 12-14 days to mature Live about 12-18 hours Not self renewing |
Neutrophils
|
|
|
Account for about 3% of WBC's
Can live for months to years Can be involved in multiple episodes of phagocytosis Nonspecific- fight several types |
Monocytes
|
|
|
Account for about 1.5% of WBC's
Elevate in an allergic reaction |
Eosinophils
|
|
|
Account for about 0.5% of WBC's
Responsible for S/S of inflammation Release chemicals like: Heparin, Histamine, and Kinis |
Basophils
|
|
|
What involves antigen - antibody interaction to destroy foreign proteins
|
Antibody-Mediated immunity
|
|
|
Most active AMI
Specific - fight specific diseases Have a memory- not the same cold more than once |
B lymphocytes
|
|
|
When we form our own antibodies, long term immunity
|
Active
|
|
|
When the antibodies are present, but you did not make them
|
Passive
|
|
|
When you are exposed to the disease in your environment
|
Natural
|
|
|
When you are purposely exposed to the disease
|
Artificial
|
|
|
Does not involve antibodies
The lymphocyte with the most active roll is the t-lymphocyte Cells involved are: helper/inducer T cells (CD4), Suppressor T (CD8), cytotoxic/cytolytic T cells |
Cell Mediated Immunity
|
|
|
Formed from stem cells in the bone marrow
Relieased into the blood stream Mature in the thymus and in lymph nodes |
T-lymphocytes
|
|
|
Recognize self from non-self
Help to stimulate production and function of cells involved in immune responses In HIV this cell is infected Dx of AIDS if these are less than 200 |
Helper/Induced T cells
CD4 |
|
|
Prevent overrecations (hypersensitivity reactions)
Prevent formation of antibodies against self (such as autoimmune disorders) These cells keep us "in check" |
Suppressor T Cells
CD8 |
|
|
Subset of suppressor cells
Most effective against parasitic organisms such as viruses, protozoa Responsible for rejection of transplated oragans and tissues |
Cytotoxic/Cytolytic T Cells
|
|
|
"Seeking and Destorying" cells
Most effective against viruses and cancer cells Responsible for rejection of transplanted organs/tissues |
Natural Killer Cells
|
|
|
This causes disease
Carrier of a disease Anything that can carry disease |
Pathogen
Vector Fomite |
|
|
Condition that effects alot of people at the same time in the same area
Condition that is local with low mortality rates Global problem |
Epidemic
Endemic Pandemic |
|
|
Frequency of a bug and how strong it is
|
Virulence
|
|
|
Death rate
Number of disease in an area |
Mortality
Morbidity |
|
|
Have the problem but not causing trouble
Contagious |
Colonization
Communicable |
