چکیده    This study evaluated whether gm2 ganglioside storage is necessary for neurodegeneration and neuroinflammation by performing β-hexosaminidase rescue experiments in neurons of hexb-/- mice. we developed a novel mouse model,whereby the expression of the human hexb gene was targeted to neurons of hexb-/- mice by the thy1 promoter. despite β-hexosaminidase restoration in neurons was sufficient in rescuing hexb-/- mice from gm2 neuronal storage and neurodegeneration,brain inflammation persisted,including the presence of large numbers of reactive microglia/macrophages due to persisting gm2 presence in this cell type. in conclusion,our results suggest that neuroinflammation is not sufficient to elicit neurodegeneration as long as neuronal function is restored. © 2012 kyrkanides et al.; licensee biomed central ltd.
