Immune surveillance by the liver

Abstract:
Receiving both portal vein blood and arterial blood, the liver is an important and critical component in the defense against blood-borne infection. To accomplish this role, the liver contains numerous innate and adaptive immune cells that specialize in detection and capture of pathogens from the blood. Further, these immune cells participate in coordinated immune responses leading to pathogen clearance, leukocyte recruitment and antigen presentation to lymphocytes within the vasculature. Finally, this role in host defense must be tightly regulated to ensure that inappropriate immune responses are not raised against nonpathogenic exogenous blood-borne molecules, such as those derived from food. It is this balance between activation and tolerance that characterizes the liver as a frontline immunological organ.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
