Peripheral venous whole blood was collected from subjects, and 0.83% ammonium
chloride was used to separate red blood cells. Whole blood was then stained with
the following fluorescent antibodies:
anti-CD24-FITC,
anti-CD19-PE,
anti-CD27-PEcy5, and
anti-CD38-APC (eBioscience, San Diego, CA, USA).
Fluorescently-stained cells were then detected by
BD FACSVerse flow cytometry
(BD Biosciences, San Jose, CA, USA). Peripheral venous blood B cells
(CD19
+ lymphocytes) were divided into Breg cells
(CD19
+CD24
hiCD38
hi), memory B cells
(CD19
+CD27
+CD24
hi), and plasma cells
(CD19
+CD27
hiCD38
hi).
