5. Wirkmechanismus
Exendin-4 entfaltet seine Wirkung, indem es an den Rezeptor für Glucagon-like Peptide-1 (GLP-1R) bindet. Diese Bindung aktiviert die Adenylatcyclase, was zu einer Erhöhung des cAMP-Spiegels führt. Das erhöhte cAMP aktiviert die Proteinkinase A (PKA), die wiederum verschiedene Zielproteine phosphoryliert, die am Glukosestoffwechsel beteiligt sind. Diese Kaskade von Ereignissen führt zu einer verstärkten Insulinsekretion, einer reduzierten Glucagonsekretion und einer verbesserten Glukosehomöostase .

Einzigartigkeit: Exendin-4 ist aufgrund seiner längeren Halbwertszeit im Vergleich zu GLP-1 einzigartig, was es für die therapeutische Anwendung effektiver macht. Zusätzlich ist seine Herkunft aus dem Gift des Gila-Monsters ein faszinierender Aspekt seiner Entdeckung und Entwicklung .
Wirkmechanismus
Exendin-4 exerts its effects by binding to the glucagon-like peptide-1 receptor (GLP-1R). This binding activates adenylate cyclase, leading to an increase in cyclic adenosine monophosphate (cAMP) levels. The elevated cAMP activates protein kinase A (PKA), which in turn phosphorylates various target proteins involved in glucose metabolism. This cascade of events results in enhanced insulin secretion, reduced glucagon secretion, and improved glucose homeostasis .

Uniqueness: Exendin-4 is unique due to its longer half-life compared to GLP-1, making it more effective for therapeutic use. Additionally, its origin from the Gila monster’s venom adds a fascinating aspect to its discovery and development .

Mechanism of Action |
Islet amyloid, formed by aggregation of human islet amyloid polypeptide (hIAPP), is associated with beta cell death in type 2 diabetes as well as in cultured and transplanted human islets. Impaired prohIAPP processing due to beta cell dysfunction is implicated in hIAPP aggregation. We examined whether the glucagon-like peptide-1 receptor (GLP-1R) agonist exenatide can restore impaired prohIAPP processing and reduce hIAPP aggregation in cultured human islets and preserve beta cell function/mass during culture conditions used in clinical islet transplantation. METHODS: Isolated human islets (n = 10 donors) were cultured with or without exenatide in normal or elevated glucose for 2 or 7 days. Beta cell apoptosis, proliferation, mass, function, cJUN N-terminal kinase (JNK) and protein kinase B (PKB) activation and amyloid formation were assessed. ProhIAPP, its intermediates and mature hIAPP were detected. Exenatide-treated islets had markedly lower JNK and caspase-3 activation and beta cell apoptosis, resulting in higher beta/alpha cell ratio and beta cell area than non-treated cultured islets. Exenatide improved beta cell function, manifested as higher insulin response to glucose and insulin content, compared with non-treated cultured islets. Phospho-PKB immunoreactivity was detectable in exenatide-treated but not untreated cultured islets. Islet culture caused impaired prohIAPP processing with decreased mature hIAPP and increased NH(2)-terminally unprocessed prohIAPP levels resulting in higher release of immature hIAPP. Exenatide restored prohIAPP processing and reduced hIAPP aggregation in cultured islets. Exenatide treatment enhances survival and function of cultured human islets and restores impaired prohIAPP processing in normal and elevated glucose conditions thereby reducing hIAPP aggregation. GLP-1R agonists may preserve beta cells in conditions associated with islet amyloid formation., Incretins, such as glucagon-like peptide-1 (GLP-1), enhance glucose-dependent insulin secretion and exhibit other antihyperglycemic actions following their release into the circulation from the gut. Byetta is a GLP-1 receptor agonist that enhances glucose-dependent insulin secretion by the pancreatic beta-cell, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying. The amino acid sequence of exenatide partially overlaps that of human GLP-1. Exenatide has been shown to bind and activate the human GLP-1 receptor in vitro. This leads to an increase in both glucose-dependent synthesis of insulin, and in vivo secretion of insulin from pancreatic beta cells, by mechanisms involving cyclic AMP and/or other intracellular signaling pathways., It has been reported that GLP-1 agonist exenatide (exendin-4) decreases blood pressure. The dose-dependent vasodilator effect of exendin-4 has previously been demonstrated, although the precise mechanism is not thoroughly described. /The aim of this study is/ to provide in vitro evidence for the hypothesis that exenatide may decrease central (aortic) blood pressure involving three gasotransmitters, namely nitric oxide (NO) carbon monoxide (CO), and hydrogen sulfide (H2S). ... The vasoactive effect of exenatide on isolated thoracic aortic rings of adult rats /was determined/. Two millimetre-long vessel segments were placed in a wire myograph and preincubated with inhibitors of the enzymes producing the three gasotransmitters, with inhibitors of reactive oxygen species formation, prostaglandin synthesis, inhibitors of protein kinases, potassium channels or with an inhibitor of the Na+/Ca2+-exchanger. Exenatide caused dose-dependent relaxation of rat thoracic aorta, which was evoked via the GLP-1 receptor and was mediated mainly by H2S but also by NO and CO. Prostaglandins and superoxide free radical also play a part in the relaxation. Inhibition of soluble guanylyl cyclase significantly diminished vasorelaxation. We found that ATP-sensitive-, voltage-gated- and calcium-activated large-conductance potassium channels are also involved in the vasodilation, but that seemingly the inhibition of the KCNQ-type voltage-gated potassium channels resulted in the most remarkable decrease in the rate of vasorelaxation. Inhibition of the Na+/Ca2+-exchanger abolished most of the vasodilation. Exenatide induces vasodilation in rat thoracic aorta with the contribution of all three gasotransmitters. /This provides/ in vitro evidence for the potential ability of exenatide to lower central (aortic) blood pressure, which could have relevant clinical importance., Glucagon-like peptide-1 receptor (GLP-1R) activation in the nucleus accumbens (NAc) core is pharmacologically and physiologically relevant for regulating palatable food intake. /An assessment was made/ whether GLP-1R signaling in the NAc core of rats modulates GABAergic medium spiny neurons (MSNs) through presynaptic-glutamatergic and/or presynaptic-dopaminergic signaling to control feeding. First, ex vivo fast-scan cyclic voltammetry showed that the GLP-1R agonist exendin-4 (Ex-4) does not alter dopamine release in the NAc core. Instead, support for a glutamatergic mechanism was provided by ex vivo electrophysiological analyses showing that Ex-4 activates presynaptic GLP-1Rs in the NAc core to increase the activity of MSNs via a glutamatergic, AMPA/kainate receptor-mediated mechanism, indicated by increased mEPSC frequency and decreased paired pulse ratio in core MSNs. Only a small, direct excitatory effect on MSNs by Ex-4 was observed, suggesting that the contribution of postsynaptic GLP-1R to MSN activity is minimal. The behavioral relevance of the electrophysiological data was confirmed by the finding that intracore injection of the AMPA/kainate receptor antagonist CNQX attenuated the ability of NAc core GLP-1R activation by Ex-4 microinjection to suppress food intake and body weight gain; in contrast, intracore NMDA receptor blockade by AP-5 did not inhibit the energy balance effects of NAc core Ex-4. Together, these data provide evidence for a novel glutamatergic, but not dopaminergic, mechanism by which NAc core GLP-1Rs promote negative energy balance. |
