Figure 8. Model of a Gs-to-Gq signaling switch for amplification of insulin secretion in persistently depolarized β cells.

Figure 8

(A and B) for normal β cell; (C and D) for persistently depolarized β cell. SU, sulfonylurea; FFA, free fatty acids; GqPCRs, Gq protein–coupled receptors; GsPCRs, Gs protein–coupled receptors. Basal and GPCR-stimulated states are shown. See text for details.
