In Brief: This case report describes the successful use of RZ358, a novel human anti–insulin receptor monoclonal antibody therapy, in a patient with severe, refractory hypoglycaemia due to metastatic insulinoma.The tumour and resulting severe hypoglycaemia had been resistant to treatments with octreotide, lutetium Lu 177 dotatate radionuclide, diazoxide, everolimus, dexamethasone, pasireotide, and glucagon – and the patient, a 55-year old man w...

Brief summary: Emont et al. created a cell atlas of human and mouse white adipose tissue, which goes a long way in informing our understanding of the complexity of adipose tissue.Although adipocytes make up the largest proportion of adipose tissue volume, the cellular structure of adipose tissue is far more complex and includes adipose tissue progenitor cells (APCs), fibroblasts, vascular cells and immune cells. We are also beginning to understa...
