Cytokines trigger endothelial cells to express specific receptors called selectins, which bind to carbohydrates on the surface of neutrophils.
Cytokines are the proteinaceous structures predominant in cell signaling. They also regulate the growth of immune cells and blood cells. They can also occur in the form of glycoproteins. The example of cytokines are interleukins, interferons, chemokines and Tumor Necrosis Factor (TNF).
Selectins are the transmembrane proteins that span the lipid bilayer only once. They belong to the family Cell Adhesion Molecules. They perform role in processes like inflammation, lymphocyte homing, immunological responses, etc. They are localized on the membranes of endothelial cells, leukocytes and platelets.

Compatibility in the ABO blood type is necessary for the blood transfusion, but that is not sufficient to determine the possible donor.
The Rh factor should also be taken into consideration when determining blood transfusion compatibility. A person can be Rh positive or negative, and the Rh positive Rh blood donors can only donate to other Rh-positive people.
