Rapid stimulatory effect of bradykinin on glucose transport across the brush-border and basolateral membranes of rat jejunal enterocytes.

Bradykinin has been shown to stimulate sugar uptake by intact intestine, but the cellular locus of this action is unknown. In this study on rat we show that bradykinin (10(-7) M) stimulates both sodium-dependent glucose uptake at the brush-border membrane and carrier-mediated movement across the basolateral membrane of upper villus enterocytes. These results suggest a role for bradykinin in the local control of glucose transport though the mechanisms underlying these effects have still to be elucidated.
