Which chemical mediator derived from mast cells retracts endothelial cells
to increase vascular permeability and to cause leukocyte adhesion to
endothelial cells? Select one.
Question options:
a) Bradykinin
b) Platelet-activating factor
c) Prostaglandin E
d) Chemokines
Hide question 1 feedback
Feedback
The biologic activity of platelet-activating factor is virtually identical to that of leukotrie
endothelial cell retraction to increase vascular permeability, leukocyte adhesion to endo
platelet activation. The other options do not accurately identify the chemical mediator d
described in the question. Chemokines function primarily to induce leukocyte chemotaxi
interact with the kinin system to stimulate nerve endings and cause pain, among other
the most important product of the kinin system and causes vascular permeability, smoot
and pain.
