Abstract
The in vitro basal insulin release and45Ca2+ uptake by rat islets of Langerhans remain unaffected by the animal's age. However, when Agaricus bisporus lectin PHA-B is added to the medium, there is a significant stimulation of basal insulin secretion and45Ca2+ uptake. The islets isolated from younger rats are more sensitive to A. bisporus PHA-B stimulation and register 1.5-fold and 3-fold more increases of insulin release and45Ca2+ uptake respectively as compared to islets isolated from 12-month-old rats. Age-related conformational changes in the B-cell membrane are suggested as a possible explanation for the above observation.
