Sepsis is defined as the systemic inflammatory response syndrome associated with an infection and is characterized by the development of clinical, haematological, biochemical and immunological associated with infection. In this context, knowing that changes in the nervous system are implicated in the induction or amplification of the change of the immune system, or conversely, conduit, have not been well elucidated in sepsis and the importance of sepsis in the mortality found and that the interaction between bacteria and their products and innate immunity cells represent a crucial moment in the pathophysiology of inflammatory diseases, it is necessary to investigate the immune changes after changes in brains of mice in an animal model of sepsis by cecal ligation and puncture (CLP). In the present study, the animals will undergo the technique of CLP to induce sepsis, later changes brain will be evaluated by testing SHIRPA. It will be evaluated by flow cytometry profile of population of T lymphocytes (CD4, CD8, Treg, T17 and B lymphocytes) and matched in these cell lines cellular viability, apoptosis, necrosis, changes in mitochondrial membrane potential and production free radical (superoxide and nitric oxide). Furthermore, the expression is evaluated by Real time PCR apoptosis.
