    The data of this study show that CXCL13 expression is a hallmark of microglial activation in Cstb (-/-) mice and that the brain inflammation is linked to peripheral inflammatory changes, which might contribute to the disease pathology of progressive myoclonus epilepsy..

    Brain inflammation is accompanied by peripheral inflammation in Cstb <sup>-/-</sup> mice, a model for progressive myoclonus epilepsy.

    Deletion of the encoding Cstb gene in Npc1-deficient mice resulted in striking deleterious effects, particularly within the cerebellum where diffuse loss of Purkinje cells was observed in young mice. This may be a consequence of damage to lysosomal membranes by reactive oxygen species (ROS), leading to the leakage of lysosomal contents that culminates in apoptosis.

    Pathologic events in the CSTB-deficient brain highlight the potential role of glial activation at the initial stages of progressive myoclonic epilepsy type 1.
