NHE8 is a research area related to the study of the sodium/hydrogen exchanger 8 protein. This protein is involved in the regulation of pH levels in various tissues and cells, and plays a role in maintaining the balance of ions within cells. Research in this area typically focuses on the structure, function, and regulation of NHE8, as well as its potential implications in various physiological processes and diseases. Studies may also investigate potential therapeutic targets or strategies related to NHE8 for treating conditions associated with disrupted pH regulation or ion balance.
