Figure 4. Immunophenotypic and molecular analyses of CX3CR1+ and CX3CR1− GC B cells.
(A) CX3CR1+ and CX3CR1− GC B cells were analyzed after staining with mAbs. Results are percent positive cells, minimum to maximum ranges from ten independent experiments. (B) VH5(D)JH-μ rearrangement sequences were evaluated in CX3CR1+ and CX3CR1− GC B cells. 104 molecular clones from five different CX3CR1+ GC B cell fractions were compared to 63 molecular clones from three different CX3CR1− GC B lymphocyte fractions. 34 molecular clones from three different CD10-CD27− naive B cell fractions were tested as controls. Results are ratios between number of mutations and number of molecular clones.
