TFR expansion in human lymph nodes (LNs) during HIV infection.(a) Representative images of immunofluorescently stained LN sections from a subject with chronic, untreated HIV infection (n=17) and an uninfected control subject (n=8). LNs were stained with fluorescently labelled antibodies to CD20 (white), IgD (blue), Foxp3 (green) and CD4 (red). Follicle (F) was defined as CD20+ (white line) and germinal centre (GC) was defined as CD20+IgD− (yellow line). Images were scanned at x 60 magnification and scale bars equal 20 µm. (b) Foxp3+CD4+ cells were quantified in different regions of immunofluorescently stained LN shown in a from uninfected (n=8) and HIV-infected (n=17) subjects using visual inspection and quantitative image analysis to determine areas. (c) The average areas of total (LN), follicular and GC regions per LN cross-section were determined by quantitative image analysis. (d) The average number of CD4+Foxp3+ cells per LN, F and GC cross-section was calculated by multiplying the frequency of CD4+Foxp3+ cells per mm2 (b) by the average area of each region (c) for each subject. The horizontal bars of each graph indicate the median value and are listed where appropriate for clarity. Statistical analyses were performed by Mann–Whitney (Wilcoxon) tests to compare unpaired, nonparametric values and significance is denoted by asterisks where *P<0.05 and **P<0.01.

補足情報

CD20 also known as MS4A1 or L26 is a membrane-spanning 4-domains subfamily A member 1 protein. It is a non-glycosylated phosphoprotein with a molecular mass of approximately 33-37 kDa. Expressed extensively on the surface of B-cells CD20 plays an important role in B-cell activation and regulation. While CD20 is absent on early pro-B cells and plasma cells its presence increases as B-cells mature. Anti-CD20 antibodies such as 2H7 are commonly used in research and treatment to deplete B-cells due to the target's consistent expression in most stages of B-cell development.
Biological function summary

CD20 contributes significantly to calcium ion transport which is essential for the activation process of B-cells. Although CD20 does not belong to a larger protein complex its role centers around forming a calcium channel that allows a sustained influx of calcium into the B-cells. This influx is important for the signaling pathways that govern B-cell activation proliferation and differentiation impacting the immune response efficacy.

Pathways

CD20 is closely involved in the B-cell receptor (BCR) signaling pathway and the Fc gamma R-mediated phagocytosis pathway. These pathways play vital roles in adaptive immunity and immune response modulation. CD20's interaction with proteins like PI3K during BCR signaling enhances receptor-mediated cellular signals subsequently influencing downstream effectors involved in cell growth and survival of B-cells.

CD20 is strongly linked to certain blood cancers and autoimmune diseases including non-Hodgkin's lymphoma and rheumatoid arthritis. These conditions often exploit aberrant B-cell activity or count. CD20's expression on malignant B-cells in non-Hodgkin's lymphoma makes it an effective target for monoclonal antibody therapies such as rituximab an anti-CD20 antibody. Additionally CD20-targeted therapies can help deplete pathogenic B-cells in rheumatoid arthritis highlighting the protein's relevance in disease treatment.
