Q

mechanism of action for immediate hypersensitivity reaction

A

macrophages present antigen to B cells, this produces IgE antibodies. the antibodies attach to mast cells after first exposure. mast cells release histamine upon second exposure. then inflammatory response reaction.

  • protein on wall of pollen released when binds to stigma, also when binds to your respiratory mucosa
  • when patient comes in contact with allergen, mast cells release histamine (steps) blood vessels “leak” thus, runny nose, watery eyes, wheel and erythematous flare.
