Field of Interest: Basic Immunology


In vivo distribution of danger associated molecular pattern molecules (DAMPs): The main goal of the Ramos lab will be to study and map the distribution of DAMPs released by dying cells in tissues during the early stages of the immune response. Specifically, our research will focus in characterizing the dissemination of the peptide N-Formylmethionine-leucyl-phenylalanine (fMLP) and its role in alerting the innate immunity, leading to early stages of the inflammatory response.
