Selectins are a group of cell adhesion molecules that play a critical role in the process of leukocyte recruitment to sites of inflammation, as well as facilitating the formation of new blood vessels (angiogenesis) during wound healing, tissue repair, and tumor growth. They are involved in cell-cell interactions by mediating the binding of leukocytes to endothelial cells or platelets, an initial step in the migration of leukocytes from the bloodstream into tissues. There are three types of selectins: L-selectin (CD62L), E-selectin (CD62E), and P-selectin (CD62P), each with a specific expression pattern and binding preference. L-selectin is mainly expressed on lymphocytes, while E-selectin is selectively expressed on endothelial cells stimulated by cytokines, and P-selectin is found on activated platelets and endothelial cells. In hematology and oncology research, selectins have been studied for their potential as drug targets. For example, blocking the interaction between selectins and their ligands has been shown to reduce inflammation in autoimmune diseases like multiple sclerosis and rheumatoid arthritis. Additionally, targeting selectins on tumors and/or endothelial cells may impede the formation of new blood vessels, which limit tumor growth and spread. Thus, understanding the mechanisms regulating selectin expression and function is crucial in developing therapeutic strategies for inflammation-related diseases and cancer treatment. The use of selectin inhibitors and modulators has shown promising results in preclinical studies, highlighting their potential in the management of diverse pathological conditions.

Description: Hematology is a branch of medicine concerning the study of blood, the blood-forming organs, and blood diseases. The word "heme" comes from the Greek for blood. Oncology is a branch of medicine that deals with prevention, diagnosis and treatment of cancer. It is very important for oncologists to keep updated of the latest advancements in oncology.
