    Correct

    • Which of the following cells are attracted to the surface of endothelium by selectins?

      Your Answer: Neutrophils

      Explanation:

      Selectins are expressed on the surface of the endothelium. P selectins are released from weibel-palade bodies and E selectins are induced by cytokines (TNF and IL-1). They bind to receptors on the neutrophils called saiyl lewis X.
