Ariana Barberá Betancourt

Research Interests

I have focused my research on the design and preclinical evaluation of new drugs for restoring immune tolerance in rheumatoid arthritis and type 1 diabetes. Specifically, I have studied mechanisms of Treg-mediated bystander suppression induced by peptides derived from HSP in ex vivo human assays and in animal models.

Keywords

immune tolerance ; heat shock proteins (hsp) ; inflammation ; regulatory T cells

Topics
