Abstract: Sepsis is a complex clinical condition and a leading cause of death worldwide. During Sepsis, there
is a derailment in the host response to infection, which can progress to severe sepsis and multiple organ dysfunction
or failure, which leads to death. Free radicals, including reactive oxygen species (ROS) generated predominantly
in mitochondria, are one of the key players in impairing normal organ function in sepsis. ROS contributing
to oxidative stress has been reported to be the main culprit in the injury of the lung, heart, liver, kidney,
gastrointestinal, and other organs. Here in the present review, we describe the generation, and essential
properties of various types of ROS, their effect on macromolecules, and their role in mitochondrial dysfunction.
Furthermore, the mechanism involved in the ROS-mediated pathogenesis of sepsis-induced organ dysfunction
has also been discussed.
