The Characteristics and Significance of Locally Infiltrating B Cells in Lupus Nephritis and Their Association with Local BAFF Expression

Figure 1

Microanatomical organization of B cells infiltrates. B-cells show a cluster-like structure in the lymph node of a healthy control (a). Serial staining for CD20 allowed classification into three different grades: grade 0, no infiltrate of intrarenal CD20-positive B cells (b); grade 1, a scattered pattern of intrarenal CD20-positive B cells (c); and grade 2, nodular aggregates pattern of CD20-positive B cells (d).
