Abstract

Cells respond to environmental stimuli using an elaborate process to propagate and amplify a signal from the cell surface to the nucleus leading to initiation of gene induction in a process termed “signal transduction”. The NFκB and MAPK pathways are two important pathways in the cellular responses during critical illness. Both pathways are composed of a series of kinases that utilize phosphorylation to activate downstream kinases. Once activated these pathways must be deactivated in order to reestablish homeostasis usually by a phosphatase. Additionally, intracellular inhibitors and epigenetic processes are important in regulating the activation of signal pathways.
