Superantigens simultaneously bind major histocompatibility complex and T-cell receptors in the absence of antigen presentation.This forced receptor interaction induces the production of pro-inflammatory chemical signals (cytokines) by T-cells.Criteria with regard to hemodynamic compromise or respiratory failure are not useful because they present too late for intervention.Sepsis is caused by a combination of factors related to the particular invading pathogen(s) and to the status of the immune system of the host.The low blood pressure seen in those with sepsis is the result of various processes, including excessive production of chemicals that dilate blood vessels such as nitric oxide, a deficiency of chemicals that constrict blood vessels such as vasopressin, and activation of ATP-sensitive potassium channels.Early recognition and focused management may improve the outcomes in sepsis.Consequentially, transcription factors such as nuclear factor-kappa B and activator protein-1, will up-regulate the expression of pro-inflammatory and anti-inflammatory cytokines.Cytokines such as tumor necrosis factor, interleukin 1, and interleukin 6 may activate procoagulation factors in the cells lining blood vessels, leading to endothelial damage.

This may include hemodialysis in kidney failure, mechanical ventilation in lung dysfunction, transfusion of blood products, and drug and fluid therapy for circulatory failure.There are four families of PRRs: the toll-like receptors, the C-type lectin receptors, the NOD-like receptors, and the RIG-I-like receptors.Invariably, the association of a PAMP and a PRR will cause a series of intracellular signalling cascades.There are a number of microbial factors that may cause the typical septic inflammatory cascade.An invading pathogen is recognized by its pathogen-associated molecular patterns (PAMPs).
