Modulation of hepatocyte sialylation drives spontaneous fatty liver disease and inflammation.

abstract：:F-type lectins are fucolectins with characteristic fucose and calcium-binding sequence motifs and a unique lectin fold (the "F-type" fold). F-type lectins are phylogenetically widespread with selective distribution. Several eukaryotic F-type lectins have been biochemically and structurally characterized, and the F-typ...
