The flagellin of candidate live biotherapeutic Enterococcus gallinarum MRx0518 is a potent immunostimulant.

Many links between gut microbiota and disease development have been established in recent years, with particular bacterial strains emerging as potential therapeutics rather than causative agents. In this study we describe the immunostimulatory properties of Enterococcus gallinarum MRx0518, a candidate live biotherapeutic with proven anti-tumorigenic efficacy. Here we demonstrate that strain MRx0518 elicits a strong pro-inflammatory response in key components of the innate immune system but also in intestinal epithelial cells.

The core planar cell polarity gene, Vangl2, maintains apical-basal organisation of the corneal epithelium.

The role of the core planar cell polarity (PCP) pathway protein, Vangl2, was investigated in the corneal epithelium of the mammalian eye, a paradigm anatomical model of planar cell migration. The gene was conditionally knocked out in vivo and knocked down by siRNA, followed by immunohistochemical, behavioural and morphological analysis of corneal epithelial cells. The primary defects observed in vivo were of apical-basal organisation of the corneal epithelium, with abnormal stratification throughout life, mislocalisation of the cell membrane protein, Scribble, to the basal side of cells, and partial loss of the epithelial basement membrane.
