The G protein-coupled pH-sensing receptor OGR1 is a regulator of intestinal inflammation. Mus musculus

OGR1 is a pH sensing G protein-coupled receptor involved in intestinal homeostasis and inflammation. Up-regulation of genes, mediated by OGR1, in response to extracellular acidification were enriched for inflammation, immune response, actin cytoskeleton and cell adhesion pathways. Overall design: Microarray profiling was performed to compare global gene expression of Ogr1 KO and WT residential peritoneal macrophages in response to an acidic pH shift (pH 6.7, 24 h)
