Risk Stratification in Chronic Lymphocytic Leukemia
The Role of the Clinical Laboratory
CD49d in CLL

November 2008
CD49d is the newest prognostic marker in CLL. It is also known as “alpha 4 integrin” and acts as an adhesion molecule for various extracellular matrix components. It is thought to mediate cell-cell interaction through the binding of VCAM-1, and also is felt to serve as a signaling receptor that influences B-cell survival through the Bcl-2 family.
