Abstract Regeneration, the ability to replace injured tissues and organs, is a phenomenon commonly associated with lower vertebrates but is also observed in mammals, in Differential Covers specific tissues.In this study, we investigated the regenerative potential of pancreatic islets following moderate beta-cell loss in mice.Using a rapid model of moderate ablation, we observed a compensatory response characterized by transient inflammation and proliferation signatures, ultimately leading to the recovery of beta-cell identity and function.

Interestingly, this proliferative response occurred independently of inflammation, as demonstrated in ablated immunodeficient mice.Furthermore, exposure to high-fat diet stimulated beta-cell proliferation but negatively impacted beta-cell function.In contrast, an equivalent slower ablation model revealed a delayed but similar proliferative response, suggesting proliferation as a common regenerative response.

However, high-fat diet failed to promote proliferation in this model, indicating a differential response to metabolic stressors.Overall, our findings shed light on the complex interplay between beta-cell loss, inflammation, and Key Chains stress in modulating pancreatic islet regeneration.Understanding these mechanisms could pave the way for novel therapeutic strategies based on beta-cell proliferation.
