My laboratory's overall interest is in cardiopulmonary pathology, particularly in relation to inflammation and infection of the Heart and the Lungs. In mechanistic terms, we are interested in understanding the interactions of these organs with specific infectious agents, the molecular signaling pathways that regulate such interactions, and the involvement of RNA interference (RNAi) and microRNA (miRNA) in these processes. The main focus areas are the following: (i) Infection of heart and lung by unicellular protozoan parasites (e.g., Toxoplasma gondii) and RNA viruses; (ii) Suppression of pulmonary innate immunity by RNA viruses, mainly respiratory syncytial virus (RSV); (iii) Reciprocal regulation of cellular miRNA by pathogens, mainly T. gondii and RSV.
