To read the full abstract: Proc Natl Acad Sci U S A. 2019;116:21401–21408.This prospective diagnostic study used desorption electrospray ionization mass spectrometry (DESI-MS) to classify thyroid nodules by their metabolic signature, and more precisely their lipid profile. DESI-MS is a technique using charged aerosols of microdroplets which are sprayed onto a surface (e.g. tissue) to desorb and ionize molecules which are then analyzed by MS...

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 ...
