(The Potential Role of Pancreatic γ-Aminobutyric Acid (GABA) in Diabetes Mellitus: A Critical Reappraisal - PMC (nih.gov))
In recent times, Untereiner et al., in their study confirmed that the administration of GABA leads to increase in β-cell mass and reverses the development of T1DM without significant effect on glucose impairment induced by high-fat diet.[36] In addition, Sohrabipour et al., in a study showed that GABA administration reduces insulin resistance via up-regulation of GLUT4 with significant amelioration of blood glucose in high fat and streptozocin-induced diabetes mellitus through reduction of glucagon receptor and inhibition of hepatic gluconeogenesis.[28]

The presence of a GABAergic system within the pancreas as a potential target for treating DM becomes more known recently. In α-cells, GABA induces membrane hyperpolarization and inhibits glucagon secretion, and this involves an insulin-mediated GABA-A-trafficking mechanism. In β-cells, GABA induces membrane depolarization and enhances insulin secretion. GABA also has beneficial effects on β-cell survival and regeneration, which results in enlarged β-cell mass. Furthermore, GABA inhibits systemic inflammatory and cytokine production, so GABA therapy in regulating islet cell function, glucose homeostasis, and autoimmunity is promising in the management of DM. Orally administered GABA is safe for humans, and acts on peripheral GABA receptors but does not affect CNS functions, since it does not cross the blood-brain barrier (BBB). Thus it represents a new therapeutic modality for both T1DM and T2DM. Furthermore, GABA-A receptor agonist like benzodiazepines improves pancreatic β-cell function and insulin sensitivity through activation of GABA-A receptors or indirectly through amelioration of diabetes-induced sympathetic over-activity and other pleiotropic effects.
Ein GABA-Mangel kann auch zu einer Hemmung der Hypophysen-Hormone wie ACTH, LH, TSH führen. Was bei mir tatsächlich der Fall ist. Das ist alles im unteren Laborbereich.
Im Februar hab ich wieder meinen Endo-Termin. Bis dahin werd ich das tapfer weiter nehmen und dann mal schauen, was Frau Doc dazu sagt.
