Safety and Effectiveness of Glargine 300 U/ml After Switching from Basal Insulins in Patients with Type 1 Diabetes: COMET-T Study.

Introduction: Appropriate glycemic control is paramount for people with type 1 diabetes (PwT1D) by the effective delivery of exogenous insulin. However, glycemic variability and the risk of severe hypoglycemia must be reliably controlled.

Methods: COMET-T is a prospective, multicenter, observational study conducted in Germany, Austria, and Switzerland during 2021-2022 to assess the effectiveness and safety of insulin glargine 300 U/ml (Gla-300) after switching from other basal insulins.

Ablation of CCL17-positive hippocampal neurons induces inflammation-dependent epilepsy.

Objective: Neuronal cell death and neuroinflammation are characteristic features of epilepsy, but it remains unclear whether neuronal cell death as such is causative for the development of epileptic seizures. To test this hypothesis, we established a novel mouse line permitting inducible ablation of pyramidal neurons by inserting simian diphtheria toxin (DT) receptor (DTR) cDNA into the Ccl17 locus. The chemokine CCL17 is expressed in pyramidal CA1 neurons in adult mice controlling microglial quiescence.
