Progranulin deficiency promotes neuroinflammation and neuron loss following toxin-induced injury
Martens LH, Zhang J, Barmada SJ, et al.
Abstract summary
Showed that progranulin-deficient microglia display exaggerated inflammatory responses and impaired phagocytosis. In the context of toxin-induced neuronal injury, GRN knockout mice show greater neuroinflammation and neurodegeneration. Progranulin regulates lysosomal function and cytokine production in microglia.
