Cl/HCO(-3) exchanger is operative in isolated enterocytes from rat jejunum.

M Tosco1, M N Orsenigo, A Faelli.   

Abstract

Enterocytes isolated from rat jejunum were tested for the existence of a Cl-/HCO(-3) exchange, previously evidenced in basolateral membrane vesicles but not in brush border. Cells were found to retain functional integrity and transport capabilities long enough to allow Cl- fluxes to be measured. Both efflux and uptake experiments indicate that a Cl-/HCO(-3) antiport, inhibited by 4,4'-diisothiocyanostilbene-2-2'-disulfonic acid (DIDS), is functional under resting conditions.
