Human neuroblastoma and medulloblastoma express abnormal ganglioside patterns especially GD2 and GM2 which are important for tumour growth. We tested the effects of L-cycloserine (L-CS), a potent inhibitor of synthesis of glycosphingolipids, on the growth, viability and expression of GD2

The mechanisms leading to the low-grade inflammation observed during obesity are not fully understood. Seeking the initiating events, we tested the hypothesis that the intestine could be damaged by repeated lipid supply and therefore participate in inflammation. In mice, 1-5

Currently, presymtomatic hematopoietic stem and progenitor cell transplantation (HSPCT) is the only therapeutic modality that alleviates Krabbe's disease (KD)-induced central nervous system damage. However, all HSPCT-treated patients exhibit severe deterioration in peripheral nervous system function characterized by major motor and

Lower Clostridium difficile spore counts in feces from C difficile infection (CDI) patients treated with fidaxomicin versus vancomycin have been observed. We aimed to determine whether environmental contamination is lower in patients treated with fidaxomicin compared with those treated with

A high-fat diet induces hypothalamic inflammation in rodents which, in turn, contributes to the development of obesity by eliciting both insulin and leptin resistance. However, the mechanism by which long-chain saturated fatty acids trigger inflammation is still contentious. To elucidate
