A mechanistic description for how soluble protein cargos are sorted into distinct vesicle classes at the level of the trans-Golgi network (TGN) has remained elusive. In a recent study in Developmental Cell, Sundberg et al. reveal that sphingomyelin and a proteoglycan mediate lipoprotein lipase sorting in the TGN.

Internal Medicine Service. University Hospital Virgen de la Victoria, Málaga, Spain.
Purpose: Genetic testing is required to confirm a diagnosis of familial chylomicronemia syndrome (FCS). We assessed the pathogenicity of variants identified in the FCS canonical genes to diagnose FCS cases.
Methods: 245 patients with severe hypertriglyceridemia underwent next-generation sequencing.

Graphical Abstract Lipoprotein lipase (LPL) mediates peripheral tissue triglyceride (TG) uptake. Hepatic ANGPTL3 (A3) and ANGPTL8 (A8) form a complex and inhibit LPL activity in the white adipose tissue (WAT) via systematic circulation. ANGPTL4 (A4) is expressed in WAT and inhibits LPL activity locally.

Background: The differential impact of serum lipids and their targets for lipid modification on cardiometabolic disease risk is debated. This study used Mendelian randomization to investigate the causal relationships and underlying mechanisms.
Methods: Genetic variants related to lipid profiles and targets for lipid modification were sourced from the Global Lipids Genetics Consortium.
Insulin Therapy for Acute Pancreatitis in a Patient With Lipase Maturation Factor 1 Mutation: A Case Report.

Acute pancreatitis is a frequent cause of hospital admission, managed with intravenous (IV) fluids, analgesia, and oral feeding when tolerated. In patients with hypertriglyceridemia-induced pancreatitis, insulin and other therapies may be necessary for disease resolution. We present a case of a patient with severe acute pancreatitis and euglycemic diabetic ketoacidosis (DKA) with known lipase maturation factor 1 (LMF1) gene mutations, which can impact insulin efficacy on triglyceride metabolism through altered lipoprotein lipase activity, successfully treated with intravenous insulin.
