    In this paper, the authors found that conditional ablation of Shp2 in mouse K14-positive corneal epithelium (Shp2K14ce-cko) impairs corneal innervation and results in corneal epithelial thinning, which resembles neurotrophic keratopathy. Furthermore, the data indicate that Shp2 signaling plays a pivotal role in corneal epithelial homeostasis.

    Transient receptor ion channels have emerged as critical channels/receptors in numerous physiological and pathological conditions. In this paper the authors discuss our current understanding of the role of macrophage transient receptor potential channel subfamily V member 4 (TRPV4) in various inflammatory conditions.

    Polydatin (PD) protects against LPS-induced vascular leakage in multiple organs and this effect is dependent on SIRT3 activation. PD enhances SIRT3-mediated deacetylation of SOD2 and CypD, thus suppressing mitochondrial dysfunction and subsequent endothelial barrier dysfunction. In addition, RAGE is involved in LPS-regulated SIRT3 signaling.

    The authors reveal that TRPV4, a thermosensitive ion channel, is constitutively active in the brain. They found that local brain temperature is increased at epileptogenic foci, and that hyperthermia lead TRPV4 over-activation and hyper-neuronal activities. Notably, brain cooling treatment drastically suppresses epileptic discharges dependent on the inactivation of TRPV4.

    The authors investigated the potential mechanisms of interleukin-33 (IL-33) in the pathogenesis of ulcerative colitis. IL-33 was found to sustain mucosal inflammation by down-regulation of protective ABCG5/8 during recovery from colitis. These results may help to increase understanding regarding the IL-33-mediated pathogenesis of ulcerative colitis and potentially contribute to creation of a novel therapeutic strategy.
