Research Interests and Biography: 

The complement system is an essential component of both the innate and adaptive immune system. It is comprised of about 50 proteins that function in a cascade-like activation process. The main outcomes of complement activation include pathogen clearance, inflammation, chemotaxis, and immune modulation, and others.  Given the essential functions of complement, the system needs to be tightly regulated. Dr. Ferreira’s specialization in the complement system began during her Ph.D. training while working with calreticulin (TcCRT) from Trypanosoma cruzi, the causal agent of Chagas’ disease. TcCRT has the ability to bind to the initiating molecules of the classical and lectin pathways, inhibiting their activity as an immune-evasion strategy. Since 2004, her research has focused on human complement regulatory proteins of the alternative pathway of complement, Factor H and properdin, which play essential roles in various inherited and acquired diseases, including cardiovascular disease. In an effort to understand how complement regulatory protein Factor H recognizes and protects cell and tissue surfaces from complement-mediated attack, her research findings have unveiled novel molecular mechanisms involved in the pathogenesis of atypical hemolytic uremic syndrome (aHUS), paroxysmal nocturnal hemoglobinuria (PNH), and age-related macular degeneration. Recently, her laboratory has defined molecular mechanisms by which complement regulatory protein Factor H limits the formation of platelet/granulocyte aggregates (PGA) and how properdin promotes PGA formation.  The laboratory has also contributed to the understanding of how properdin may participate in the pathogenesis  of PNH and aHUS.  Her main research focuses currently on understanding the molecular mechanisms involved in properdin structure/function in health and disease. Defining these mechanisms may identify new ways to treat and/or prevent inflammatory diseases.

Dr. Ferreira received a D.V.M. degree from The University of Chile School of Veterinary Medicine and, subsequently, a Ph.D. in Biomedical Sciences from The University of Chile School of Medicine.  She completed her postdoctoral training at the University of Texas at Tyler and joined the Department of Medical Microbiology and Immunology in July 2009 as an Assistant Professor and was promoted to Associate Professor with tenure in 2015. Dr. Ferreira has completed a 4 year standing member term on the Innate Immunity and Inflammation NIH study section, a 3 year term on the American Association of Immunology Program Committee, and a 6 year term as a Councilor on the Board of the International Complement Society. She currently serves as the elected Treasurer/Officer on the Board of the International Complement Society, is Editor-in-Chief of the journal Immunobiology and is an Associate Editor for the Journal of Immunology.
