Abstract
En 中文
• Amylin-based therapies are emerging beyond GLP-1 obesity pharmacology • New amylin analogs may be better tolerated than GLP-1 therapies • AMYR/CTR selectivity may shape both weight-loss efficacy and tolerability • Hindbrain–parabrachial circuits may separate satiation from aversion • Long-acting amylin analogs differ in receptor kinetics and brain access
