CD68
CD68: A Comprehensive Guide to Its Role in Health and Disease
Description
CD68 is a glycoprotein that is expressed on the surface of macrophages, which are immune cells that play a crucial role in the body's defense against infection and inflammation. CD68 binds to various ligands, including hemoglobin, β-glucans, and oxidized low-density lipoprotein (LDL), and is involved in the phagocytosis (ingestion) of these molecules.
Associated Diseases
CD68 expression is elevated in a wide range of diseases, including:
- Inflammation and Infection: CD68 is a marker of macrophage activation in response to inflammation and infection. Its expression is increased in diseases such as sepsis, rheumatoid arthritis, and inflammatory bowel disease.
- Cardiovascular Disease: Elevated CD68 expression is associated with atherosclerosis, a condition characterized by the buildup of plaque in the arteries. This suggests a role for CD68 in the progression of cardiovascular disease.
- Neurological Disorders: CD68 expression is increased in the brain after stroke and in neurodegenerative diseases such as Alzheimer's and Parkinson's diseases. This suggests that CD68 may play a role in the inflammatory processes associated with these conditions.
- Cancer: CD68 expression is often elevated in cancer cells, where it is associated with increased cell proliferation, invasion, and metastasis. Targeting CD68 has emerged as a potential therapeutic strategy for certain types of cancer.
Did you Know ?
- In patients with acute myeloid leukemia (AML), higher CD68 expression is associated with a worse prognosis. Studies have shown that patients with high CD68 expression have a lower survival rate and a higher risk of relapse.
