Promising Role of CD200 Expression in Diagnosis and Prognosis of Chronic Lymphocytic Leukemia: A Review

One of the most common leukemia in the world is chronic lymphocytic leukemia (cll).cll, as an incurable malignant disorder of b-lymphocytes. cd200, formerly known as ox-2, is a type i glycoprotein that is expressed on a variety of cell types. cd200 plays a vitalrole in the modulation of the immune system and is upregulated on the surface of numeroustumors, including chronic lymphocytic leukemia. in several studies, it is noted that cd200was upregulated 1.6- to 5.4-fold in b cells from all patients with b-cll and may suggestthat cd200 upregulation is an early event in the b-cll disease process. it might concludethat cd200 blocking therapy may be beneficial, and several studies have proven this. we canconclude that cd200 is an excellent prognostic factor that expresses in most cll patients,and anticd200 therapeutic interventions can be useful. this literature review article wasconducted with the purpose of role of cd200 expression in the diagnosis of chroniclymphocytic leukemia.
