Figure 1 Hypothetical model of intraislet cell interaction.
Notes: ① Paracrine hyperpolarizing effects of GABA. ② Autocrine depolarizing effects of GABA. ③ GABA–GABAAR-Ca2+ -PI3K/Akt pathway. ④ Autocrine insulin action. ⑤ Intraislet glucagon action. There is an expanded discussion of these events in other reviews.Citation91,Citation92(\p)(p)Abbreviations: GABAAR, γ-aminobutyric acid type A receptor; IR, insulin receptor; VGCC, voltage-gated calcium channel; Gcgr, glucagon receptor; PI3K, phosphatidylinositol 3 kinase; Akt, protein kinase B.
