N Engl J Med. 2021;385(6):503-15. doi: 10.1056/NEJMoa2107519.PubMed ID: 34170647Brief summary: this randomized control trial in 1879 adults with type 2 diabetes compared effects of once-weekly Tirzepatide (5, 10 or 15 mg) versus once-weekly Semaglutide (1 mg) on glycemic control. After 40 weeks, all doses of Tirzepatide were superior to Semaglutide on lowering HbA1c.Gluca...

Cell Metabolism 2022;34(5):667-80.e6. doi: 10.1016/j.cmet.2022.03.006Brief Summary: In preclinical models and a phase 1 trial, a powerful new lipid small molecule was shown to act through a mechanism distinct from those of known hypolipidemic agents. Targeting HNF-1α may be a new therapeutic strategy.Comment: Familial hypercholesterolemia (FH) is the most common...

Brief summary: In this experimental study, pancreas-derived mesenchymal stem cells (PMSCs) were implanted into the kidney capsule of mice with streptozotocin (STZ)-induced diabetes. PMSCs led to increased levels of IL-6 in T-helper 1 and T-helper 17 cells, which transiently activated tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), which in turn decreased levels of interleukin-17. This was associated with exocrine pancreas regeneration and rescue of ...
