Replication Data for: Polystyrene nanoplastics drive β-cell dedifferentiation through dendritic cell-intrinsic MHC-I-dependent inflammatory crosstalk
Original title: Replication Data for: Polystyrene nanoplastics drive β-cell dedifferentiation through dendritic cell-intrinsic MHC-I-dependent inflammatory crosstalk
Summary
Scientists exposed rats to nanoplastics (tiny plastic particles like those found in bottled water and packaged food) and found they can trigger immune cells in the pancreas to send inflammatory signals that cause insulin-producing cells to lose their identity and stop working properly. This matters because it suggests a possible biological pathway linking everyday plastic exposure to blood sugar problems and diabetes risk, though this study was done in rats, so more research is needed to confirm the same happens in humans.
This dataset contains single-cell RNA sequencing (scRNA-seq) profiles of pancreatic tissues collected from rats exposed to polystyrene nanoplastics (PS-NPs) and corresponding control animals. The study was designed to investigate the cellular and molecular mechanisms underlying PS-NP-induced pancreatic dysfunction, with a particular focus on immune–endocrine interactions and β-cell dedifferentiation.
