N368 Final Immunmodulators and Antibiotics Flashcards
immunomodulator
can increase or decrease the immune system
ex have transplanted organ to prevent resistance you would use
immunomodulator
Immunoglobulins
passive immunity; antibody
immunostimulants
interferon - stimulates body defenses so that microbes or cancer cells can be more effectively attacked
immunosuppressant
suppress body defenses to prevent transplanted organ from being rejected *glucocorticoid *antibodies antimetablites *calcineric
nonspecific body defense
called innate defense
barrier to microbes
GENERAL RESPONSES THAT ARE NOT SPECIFIC TO A PARTICULAR THREAT - EX PHAGOCYTE, NATURAL KILLERS
kinin system
releases cytokine to provide antiviral property
Second line of defense in body
IMMUNE RESPONSE
*B cell and T cell
B cell are initially _____
- immunocomputent
* mature when specific to an antigen
plasma cell is a ________ B cell
mature B cell
plasma cells produce what TWO things?
IMMUNOGLOBULINGS - IgM, IgG, IgE, IgA
Initially will have IgM
then as recovering you will have IgE
IgA found in secretion glands
Also produces MEMORY CELLS
MEMORY CELLS DO WHAT?
TAKES 10 DAYS MAKING ENOUGH IgM and IgG normally, but the memory cells allow for an acceleration of this
Can only be activated if exposed to the particular programmed antigen
Booster shots are necessary for?
because overtime memory cell numbers decrease, vaccine schedules usually requires 4 shots
T cells
- HELPER T Cell: activates other T cells and communicates with B cells
- Cytotoxic Te Cells: travel through body killing pathogens and cancer
- Suppressor T cell
- Memory T cell
Why is HIV so problematic?
because it targets helper T cells
Suppressor T cell
down regulate antibody for self antigen; so your body does not attack itself
Cytokines do what to macrophages
enhance killing power of macrophage
Active immunity requires?
- exposure to antigen
- Attenuated or inactivate antigen for vaccine then the human will make antibody specific to the antigen; this first exposure makes memory cells for the antigen to help boost antibody production faster when exposed to pathogen.
Passive Immunity is obtained
when breast fed getting IgA passively which is an antibody and not the antigen, so cannot make memory cells
or when artificially it fades within 4-6 months USED FOR IMMUNOSUPPRESSED PEOPLE
CMV, HepB, RhGAM (baby and mother difference), Tetanus, Rabies are examples of diseases that need what pharmacologic intervention.
immunoglobulins
Passive immunity
only good for 4-6 months
MMR is an example of what type of vaccine
Active
inactivated vaccine examples
polio
influenza
HepA
HibTITER requires how many shots?
4 series
