| RESEARCH
INTERESTS: (Molecular Immunology) In jawed
vertebrates, adaptive immune responses are mediated by T
and B lymphocytes. Displayed on the surface of
these cells are highly diverse receptor proteins, which
allow specific recognition of the vast array of antigens
that an organism normally encounters. I am
interested in lymphocyte development, the molecular
events occurring at the DNA level that generate antigen
receptor diversity, and their impacts on genomic
stability and the development of lymphoid tumors. Specifically, we studyV(D)J
recombination, which assembles the genes encoding the
antigen binding portions of antigen receptors during
lymphocyte development. This is a DNA cut and
paste, mix and match process in which individual gene
segments are brought together in different combinations
to generate a variety of receptors. This process
requires a lymphocyte-specific DNA cutting nuclease
(consisting of RAG proteins), and ubiquitous DNA double
strand-break repair proteins that help to reseal the
breaks. Current Projects: 1. We have recently received funding from the
National Institute of Allergy and Infectious Disease of
the National Institutes of Health to study the timing
and tissue specificity of aberrant and ectopic V(D)J
rearrangements in mice potentially leading to genomic
instability and tumor development. 2. Collaboration
with Dr.
John
O'Reilly:
Studies involve site-directed mutagenesis and
structure-function analysis of human sodium channels.
This project is funded by an NIH Area Grant from the
National Heart Lung and Blood Institute and has been
renewed through 2012. |
