CPT1C malonyl-CoA sensing was key to the regulatory role on ABHD6 activity and CB receptor signalling. Fasting, which attenuates brain malonyl-CoA, significantly increased ABHD6 activity in hypothalamus from WT, but not CPT1C-KO, mice. Our finding that negative regulation of ABHD6 activity, particularly in the hypothalamus, is sensitive to nutritional status throws new light on the characterization and the importance of the proteins involved as potential targets against diseases affecting the CNS.

Hemolytic disease of the fetus and newborn (HDFN) attributable to anti-M is rare, although case reports implicate anti-M in varying severities of HDFN, including fetal hydrops and intrauterine death. We describe the case of a newborn with HDFN associated with an atypical immunoglobulin (Ig) G anti-M that reacted best at cold temperatures. The maternal antibody detected in pregnancy was not reactive at 37°C, and a direct antiglobulin test (DAT) on red blood cells (RBCs) from the newborn was negative, suggesting an anti-M that should not have been clinically relevant. However, the infant developed hyperbilirubinemia (bilirubin level, 17.6 mg/dL), hemolytic anemia (hemoglobin nadir, 5.5 g/dL), and reticulocytopenia. Laboratory testing demonstrated the presence of an IgG anti-M in maternal and neonatal samples reacting best at 4°C. This passively acquired IgG anti-M provoked hemolytic anemia in the infant and likely suppressed erythropoiesis, resulting in reticulocytopenia with prolonged anemia. He was treated for IgG anti-M HDFN with 10 intravenous Ig infusions and 10 days of oral pred
