  • Gene regulation in the immune system
  • T-cell phenotyping in immune conditions
  • Biology and pharmacology of human type 2 T cells

Past Research

Our research has long been devoted to the study of the regulation of transcription of cytokine genes in polarized T cells and in basophils/mast cells. In particular, our laboratory is focused on the identification and pharmacological manipulation of factors uniquely involved in the regulation of the type 2 cytokines, interleukin (IL)-4 and IL-13, at both the transcriptional and epigenetic levels. These include factors of the NF-?B/Rel family, especially p65 and p50, and of the novel family of Grainyhead-related proteins, including LBP-1c/LSF/CP2 and its related proteins, LBP-1a and -1d. 

Current Research

It is the aim of our laboratory to fully elucidate the mechanisms that account for polarized cytokine profiles in effector T helper (Th) cells. Our current studies are testing the central hypothesis that these processes depend to a significant extent on the balance of NF-?B molecular species and the specific interactions of these proteins with other nuclear factors, e.g. Bcl-3 and C/EBP?, and chromatin-modifying agents.
In parallel studies we are assessing the mechanistic and clinical implications of recent studies identifying certain surface molecules as phenotypic and functional determinants of polarized Th cells. Specifically, we have focused on the chemokine receptor, CCR5, and on the structurally related PGD2 receptor, CRTH2, as faithful, selective markers for human Th1 and Th2 cells, respectively. Our studies are aimed at (i) characterizing the phenotypes of cells expressing CCR5 or CRTH2, (ii) understanding the function of either marker in differential regulation of Th-cell gene expression program, and (iii) assessing the prevalence and function of CCR5- and CRTH2-expressing Th cells in immune conditions associated with and possibly caused by imbalanced immune responses, e.g. asthma and systemic sclerosis (scleroderma).
