Astrocyte-specific expression of a soluble form of the murine complement control protein Crry confers demyelination protection in the cuprizone model.

abstract：:In the cerebellar cortex, Bergmann glia enclose the synapses of both parallel and climbing fiber inputs to the Purkinje neuron. The glia express Ca(2+)-permeable AMPA receptors, and the GLAST and GLT-1 classes of glutamate transporter, which are activated by glutamate released during synaptic transmission. We have pre...

abstract：:Toll-like receptors 7 (TLR7) and 9 (TLR9) are important mediators of innate immune responses. Both receptors are located in endosomal compartments, recognize nucleic acids, and signal via Myeloid differentiation factor 88 (MyD88).
