Innate B1 Cells found in Humans

After many years of research, Dr. Rothstein's team of investigators from the Feinstein Institute has found this unique population of B1 cells, which were hiding in plain sight. It seems that they reside among the same population of B cells that are built one by one when the body comes in contact with millions of infectious bugs over a lifetime -- so-called adaptive or memory B cells. The key was finding the particular markers that differentiate B1 cells from every other B cell type. The results of the study were published in the Journal of Experimental Medicine this week.
