Scientific Interest(s):

All blood cells, including B- and T-lymphocytes, are derived from a common precursor known as the hematopoietic stem cell. B- and T-cells are the principal cells involved in the production of antibodies and in the defense against viruses and tumors. If the number of mature B- and T-cells produced is not normal, individuals may be more prone to infection and disease. At the other end of the spectrum, overproduction of B- and T-cells and/or their precursors may occur in various forms of leukemia. The aim of Dr. Kenneth Dorshkind's laboratory is to study how B- and T-cells normally develop in order to have a basis for understanding defects in their production.

B- and T-lymphocytes are produced in the bone marrow and thymus, respectively, and are the principal effectors of immunity. One aim of Dorshkind's work is to characterize immature lymphoid progeny derived from the pluripotential hematopoietic stem cell during fetal and adult life. He and his colleagues are particularly interested in defining branch points at which precursors lose their multipotentiality and become committed to generating either B- or T-cells. Another aim of the Dorshkind laboratory is to identify age-related changes in the hematopoietic system and determine how they may contribute to abnormal blood cell development and function.
