Granulocyte adhesion

Granulocyte adhesion" is not a specific molecule or receptor, but rather describes a biological process in which granulocytes (a type of white blood cell, including neutrophils, eosinophils, and basophils) adhere to the endothelial cells lining blood vessels as part of the immune response. This process is essential for granulocytes to exit the bloodstream and migrate into tissues during inflammation or infection[1][5]. The mechanism involves multiple classes of molecules—primarily cell adhesion molecules such as selectins, integrins, and members of the immunoglobulin superfamily (e.g., ICAMs and VCAMs)[1][5][8]. These proteins mediate rolling, firm adhesion, and transmigration steps that allow granulocytes to reach sites of tissue damage or infection. Because "granulocyte adhesion" refers to a pathway/process involving many molecular players rather than a single targetable entity (such as a receptor or enzyme), it should not be considered a canonical therapeutic target itself. Instead, individual molecules within this pathway—such as LFA-1 (an integrin), ICAM-1/VCAM-1 (immunoglobulin superfamily members), selectins, etc.—are potential drug targets[5][6][8]. If you are seeking structured information about druggable targets involved in this process, you should focus on specific cell surface proteins like "LFA-1," "ICAM-1," "E-selectin," etc., rather than the general term "granulocyte adhesion."
