WebMar 10, 2024 · These targets include surface markers (e.g., the CD20 antigen) and also cell signaling mechanisms (e.g., B-cell receptor signaling and BCL-2 signaling). The CD20 Marker and Rituximab Healthy B-lymphocytes have an antigen, or marker, on the surface called CD20, and so do many of the B-cell lymphomas. MBL falls into three phenotypes that are distinguished based on the cell surface marker proteins which they express viz., the CLL/SLL, atypical CLL/SLL, and non-CLL/SLL phenotypes. These markers are: CD5, CD19, CD20, CD23, and immunoglobulins (Ig) (either Ig light chains or complete Ig, i.e. light chains bound to Ig heavy chains. Distinguishing between these phenotypes is important because they progress to different lymphocyte malignancies. The following table give…

WebThe CLL cells express CD5, CD19, CD23, CD43, and HLA-DR and are weakly positive for surface Ig, CD20, and CD11c (Figures 15.10 and 15.11). The expression of CD22, CD79a, and FMC7 is weak or absent. The CLL cells are negative for CD10 and bcl-1, and in some cases may express CD25, CD38, ZAP-70, and CD79b [27–31].
