Autotaxin induces fibrosis in lamina cribrosa cells in glaucoma

Lysophosphatidic acid (LPA) and the enzyme that generates it, autotaxin, have been shown to play a role in fibrosis in the trabecular meshwork in glaucoma, contributing to increased intraocular pressure. We wished to investigate the role of LPA and autotaxin in fibrosis of the la...

NKCC1 coordinates SPAK-PP1 signalling to regulate KCC2 membrane stability and seizure susceptibility.

Chloride homeostasis, and thereby the efficacy of chloride-permeable GABAA receptor signaling, depends on the dynamic balance between NKCC1 (Na+-K+-2Cl- cotransporter 1) and KCC2 (K+-Cl- cotransporter 2), which respectively mediate chloride influx and extrusion to tightly control...
