CARRILLO ESPER, Raúl et al. Molecular basis of sepsis. Rev. Fac. Med. (Méx.) [online]. 2014, vol.57, n.3, pp.9-21. ISSN 2448-4865.

Sepsis continues to be a primary cause of high mortality and morbidity in critically ill patients. Despite constant growth in dedicated basic investigation and numerous clinical studies, no remarkable developments have been made for effective and innovative therapies. The physiologic disorders induced by sepsis are primarily due to the overwhelming immune response to invading pathogens rather than the direct effects caused by the pathogen.

Sepsis, understood as the systemic inflammatory response to infection is characterized by the unregulated production of proinflammatory cytokines. These mediators collectively lead to multiple organ failure and eventually to death. In this context, the role of inflammation in the physiopathology of sepsis, though not fully understood, is of critical importance. This review provides a perspective of the most current understandings of the molecular mechanisms during sepsis, which may provide an attempt to understand the nature of this unregulated response of the immune systems during sepsis.
