The focus of the research in my laboratory is to study the cellular interactions, the environmental cues and the molecular mechanisms that control the differential capacity of distinct populations of dendritic cells (DCs) to regulate effector, memory T cell responses and T follicular helper (Tfh) cell differentiation in different models of infection and autoimmune disease. In addition, we are studying the role of Tfh cells in Systemic Lupus Erythematosus (SLE or Lupus) and Rheumatoid arthritis (RA). We found that IL-2 availability is a critical factor that controls Tfh development in vivo and that exogenous IL-2 administration prevents aberrant accumulation of Tfh and GC B cell in lupus-prone mice. We are now exploring the potential therapeutic use of IL-2 in SLE and RA.
