The carbonic anhydrases (CAs) participate in the maintenance of pH homeostasis in various tissues and biological fluids of the human body by catalysing the reversible reaction CO2 + H2O HCO3- + H+ (Davenport & Fisher, 1938; Davenport, 1939; Maren, 1967). Carbonic anhydrase isoenzyme VI (CA VI) is the only secretory isoenzyme of the mammalian CA gene family. It is exclusively expressed in the serous acinar cells of the parotid and submandibular glands, from where it is secreted into the saliva. In this review, we will discuss recent advances in research focused on the physiological role of salivary CA VI in the oral cavity and upper alimentary canal.
碳酸酐酶(CAs)通过催化可逆反应CO2 + H2O⇌HCO3- + H+,参与维持人体各种组织和生物体液中的pH稳态(达文波特和费舍尔,1938年;达文波特,1939年;马伦,1967年)。碳酸酐酶同工酶VI(CA VI)是哺乳动物CA基因家族唯一的分泌型同工酶。它仅在腮腺和颌下腺的浆液性腺泡细胞中表达,并从那里分泌到唾液中。在这篇综述中,我们将讨论聚焦于唾液CA VI在口腔和上消化道生理作用的研究最新进展。
