Dr. J. Lee Nelson (right) has been studying the fascinating phenomenon of microchimerism in the context of autoimmune disorders ever since she joined the Fred Hutchinson Cancer Research Center faculty in 1986. Microchimerism refers to the presence of two distinct sets of cells in one individual and is surprisingly common as a result of cell exchange between mother and child during pregnancy. The numbers of these outside cells is typically small, but Dr. Nelson's research has implicated them in various autoimmune responses, both positive and negative.
