Abstract

The insulin-secretory responsiveness of four popular and widely used insulin-secreting cells lines (RINm5F, HIT-T15, INS-1 and BRIN-BD11 cells) to a range of stimuli including glucose, amino acids, neurotransmitters, peptide hormones and sulphonylureas was studied. Differences were seen in the pattern of responsiveness of the cell lines to the various modulators of insulin release. While these studies revealed that INS-1 cells had the highest insulin content, only BRIN-BD11 cells exhibited a significant step-wise insulin secretory response to increasing glucose concentrations. BRIN-BD11 cells also showed pronounced insulin responses to leucine, KIC, L-arginine, L-alanine and palmitic acid. All the cell lines tested gave significant responses to the neurotransmitters carbachol and glibenclamide with increased insulin release. A comparison was made between the functional characteristics of the various cell lines with those of freshly isolated rat islets. This illustrated the general value of each cell line as a model for studies of insulin secretion. Electrofusion-derived BRIN-BD11 cells appeared to closely mimic the glucose sensitivity and overall secretory performance of normal rat islets.
