Regulação do Sistema Imunitário

Os tecidos epiteliais como a pele, o sistema respiratório e o sistema gastrointestinal funcionam como uma barreira entre o nosso organismo e os fatores externos. Estes tecidos para além de formarem uma barreira física que impede a passagem de agentes invasores, também incluem diversas células do sistema imunitário, que constituem a primeira linha de defesa contra microorganismos patogénicos.

A investigação que desenvolvemos pretende estudar a função das células do sistema imunitário na iniciação, modulação e resolução da resposta imune nos tecidos epiteliais, bem como na regulação da homeostase das células epiteliais. Este estudo pretende esclarecer os mecanismos que controlam a manutenção, ativação e função das células do sistema imunitário localizadas nas mucosas ou que se acumulam nestes tecidos. Deste modo, o objetivo do nosso laboratório é contribuir para a prevenção de respostas imunes indesejadas que podem resultar em infecções crónicas, alergias, doenças auto-imunes e risco aumentado de cancro.
