概括

研究人员开发了一个人性化的GLP-1受体 (hGLP1R) 鼠标模型,用于更好的肥胖药物的临床前测试. 这个模型准确地预测了人性化的GLP-1受体激动剂如何影响体重和新陈代谢.

科学领域:

药理学药理学是指药理学的学科.
代谢性疾病研究研究
翻译医学是一种翻译医学.

背景情况:

可注射的基于的葡萄糖类-1受体激动剂 (GLP1RAs) 面临合规性和可扩展性问题.
口服小分子GLP1RAs有希望,但缺乏在动物模型中的临床前验证.
在评估肥胖和糖尿病的新型GLP1RA时存在翻译差距.

研究的目的:

设计和验证一个人性化的GLP-1受体 (hGLP1R) 鼠标模型.
加强口服小分子GLP1RAs的临床前评估.
为了弥合GLP1R激动剂药物开发中的翻译差距.

主要方法:

使用CRISPR-Cas9基因替代生成的hGLP1R小鼠.
药理学特征的 (semaglutide) 和小分子 (或forglipron) GLP1RAs.
在瘦身和饮食诱导肥胖 (DIO) 小鼠中利用免疫组织化学和3D全脑成像.

主要成果:

hGLP1R小鼠表达了人类的GLP1R,缺乏小鼠GLP1R.
在瘦肉的hGLP1R小鼠中,semaglutide和orforglipron都降低了体重,食物摄入量,并改善了葡萄糖耐受性.
在野生型小鼠中,Orforglipron是不活跃的,突出显示了该模型的特异性.

结论:

hGLP1R小鼠模型是临床前GLP1RA研究的验证平台.
这种模型有助于发现和评估新的小分子GLP1RAs.
它有助于开发肥胖和代谢疾病的治疗方法.

Glucagon-like Receptor Agonists

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
