Question

part 3 (1 point) the following graphs show the number of adherent leukocytes found on the blood vessel wall in control conditions and after adding a selectin inhibitor, which blocks the function of selectin. which of the following graphs correctly shows the effect of a selectin inhibitor on adherence of leukocytes to the vessel wall? choose one: a. graph a b. graph b c. graph c d. cannot be determined from this experiment. (a) number of adherent leukocytes/mm² 0 500 1000 1500 2000 2500 3000 3500 4000 control drug added (b) number of adherent leukocytes/mm² 0 500 1000 1500 2000 2500 control drug added (c) number of adherent leukocytes/mm² 0 500 1000 1500 2000 2500 control drug added graph b data is from blood 2010 sep 9; 116(10): 1779 - 1786

Explanation:

Selectin is involved in leukocyte - vessel wall adhesion. A selectin inhibitor would block this function, reducing the number of adherent leukocytes. Graph B shows a decrease in the number of adherent leukocytes when the drug (selectin inhibitor) is added compared to the control.

Answer:

B. Graph B
