Academic Interests

Dr. Alegre is interested in T cell tolerance. She studies peripheral mechanisms that contribute to inhibiting T cell activation such as CD4+/CD25+ regulatory T cells and surface receptors that limit T cell expansion (CTLA-4 and PD-1). She has shown that cross linking or over expression of CTLA-4 can reduce allograft rejection and prevent autoimmunity in animal models. She is currently studying the role of NF- B activation in T cells in autoimmunity models.
