3-o-sulfo-galactosylceramide Analogs for Targeting Lung Metastases
Summary:
Lung metastases represent a major clinical challenge in advanced cancer, with poor survival rates and no effective therapies to prevent their development. Researchers at the National Cancer Institute (NCI) have developed C24:2, a first-in-class synthetic 3-O-sulfo-galactosylceramide analog. After lysosomal processing by dendritic cells, C24:2 switches immune specificity to activate type I NKT cells, triggering a potent IFN-γ–mediated Th1 response.
