The release of extracellular vesicles (EVs) from microglia may play a key role in driving neurodegeneration in Sanfilippo syndrome. EVs are tiny particles that carry a variety of cargo, such as proteins and DNA, between cells to facilitate cell-to-cell communication. Microglia are a class of immune cells in the…

A Phase 1 clinical trial in Japan that’s testing JCR Pharmaceuticals‘ experimental enzyme replacement therapy JR-441 for treating Sanfilippo syndrome type A has dosed its first patient.
