最近的报道确定GABA信号通路的激活是诱导胰腺α细胞转分化为β细胞的手段。这些报告遵循了先前的几项研究,这些研究发现α细胞特别适合在小鼠中转化为β细胞,但只有在β细胞几乎完全丧失或关键转录调节因子被迫过表达之后。通过用小分子重编程α细胞来增加β细胞数量的可能性是诱人的,因为这可能是糖尿病的潜在新药物治疗。在这里,我们使用Glucagon-CreERT 2;Rosa-LSL-eYFP小鼠对α细胞进行了严格的遗传谱系追踪,以评估GABA信号传导的激活是否导致α至β细胞重编程。与之前的报道相反,我们发现,即使用青蒿琥酯或GABA长期治疗小鼠,也不会刺激α-至-β细胞转分化或胰岛素分泌,从而质疑这些药物是否代表了一种新的糖尿病治疗的可行途径。
Recent reports identified activation of the GABA signaling pathway as a means to induce trans-differentiation of pancreatic α cells into β cells. These reports followed several previous studies that found that α cells were particularly well-suited to conversion into β cells in mice, but only after nearly complete β cell loss or forced overexpression of key transcriptional regulators. The possibility of increasing β cell number via reprograming of α cells with a small molecule is enticing, as this could be a potential new pharmacologic therapy for diabetes. Here, we employed rigorous genetic lineage tracing of α cells, using Glucagon-CreERT2;Rosa-LSL-eYFP mice, to evaluate if activation of GABA signaling caused α-to-β cell reprogramming. In contrast to previous reports, we found that even after long-term treatment of mice with artesunate or GABA, neither α-to-β cell trans-differentiation nor insulin secretion were stimulated, putting into question whether these agents represent a viable path to a novel diabetes therapy.
