abstract = {Liver sinusoidal endothelial cells (LSECs) rapidly clear
lipopolysaccharide (LPS) from the bloodstream and establish
intimate contact with immune cells. However, their role in
regulating liver inflammation remains poorly understood. We
show that LSECs modify their chemokine expression profile
driven by LPS or interferon-γ (IFN-γ), resulting in the
production of the myeloid- or lymphoid-attracting chemokines
CCL2 and CXCL10, respectively, which accumulate in the serum
of LPS-challenged animals. Natural killer (NK) cell exposure
to LSECs in vitro primes NK cells for higher production of
IFN-γ in response to interleukin-12 (IL-12) and IL-18. In
livers of LPS-injected mice, NK cells are the major
producers of this cytokine. In turn, LSECs require exposure
to IFN-γ for CXCL10 expression, and endothelial-specific
Cxcl10 gene deletion curtails NK cell accumulation in the
inflamed livers. Thus, LSECs respond to both LPS and
immune-derived signals and fuel a positive feedback loop of
immune cell attraction and activation in the inflamed liver
tissue.},
