Q

what is primary and subsequent response to a vaccination

A

primary - B & T cells activated - slow

subsequent quicker as 1000s memory cells present to proliferate/differentiate into active B & T cells

Q

antibody-antigen complexes form aggregates which aren’t cleared and deposited in various tissues (esp skin, kidney, joints) triggering immune response - activate complement system
IgG, IgM, IgA mediated
onset 4-8 hrs

Q

cell-mediated NOT antibody-mediated
over reaction of T lymphocytes to an antigen
massive clonal expansion creates loads cytotoxic T cells which damages normal tissues
delayed onset - 48-72 hrs

A

skin graft rejection

Q

allergy - initial & subsequent exposure

A

initial causes sensitisation - -slow as not specificity (not activated)
second - exaggerated immune response as has been developed and antibodies are ready

Q

4 functions of complement system

A

29
how to NK cells operate (what do they contain)
perforin - inserts into plasma membrane
30
what is are released by mast cells/basophils that attract phagocytes and aids their adherence to pathogens
