Maite Sanchez-Aparicio, Ph.D.

Research Assistant Professor





Research Interests
The goal of my work is to understand the mechanisms involved in the innate immune response against viral infections. I am mainly focused on identifying and characterizing the spatio-temporal events in the RIG-I like receptor pathway that lead to the production of type I IFN, and the mechanisms underlying the inhibition of this response by viruses. I currently work on different projects involving different RNA viruses, combining techniques from microscopy, cell biology, virology and biochemistry. In particular, we have developed a Bimolecular Complementary Assay (BiFC) to characterize the interaction between viral and host cell proteins.
