Her laboratory uses biochemical and genetic approaches to elucidate the molecular pathways that regulate CD4 T helper cell development and activation. The complex regulatory pathways governing Thelper1/Thelper2 (TH1/TH2) responses are critical for both the development of protective immunity and for the pathophysiologic immune responses underlying autoimmune diseases. This developmental event is regulated by the IL-4 and IFNg cytokines. Dr. Glimcher’s laboratory has studied the transcriptional pathways that control this important immune checkpoint. The laboratory defined the genetic bases of both IL-4 and IFNg expression in T cells. Her group identified the proto-oncogene c-maf as the transcription factor responsible for TH2-specific IL-4 expression. Subsequently, her group discovered the first TH1-specific transcription factor, T-bet and demonstrated that this single factor is a master-regulator of IFNg gene expression and the TH1 phenotype and controls Type 1 immunity in cells of both the adaptive and innate immune system. She has expanded her interest in lineage commitment in lymphocytes to the B cell with the discovery of a transcription factor, XBP-1 that controls plasma cell differentiation and the Unfolded Protein response. Most recently her laboratory has identified new proteins that control osteoblast commitment and activation. This body of work may provide a conceptual framework to therapeutically manipulate these responses in the settings of inflammatory and autoimmune diseases and cancer.
