IFN-gamma and IL-4 differentially shape metabolic responses and neuroprotective phenotype of astrocytes.

abstract：:Brain-derived neurotrophic factor (BDNF) promotes the survival of various neuronal populations and thus shows potential in the treatment of neurodegenerative disease. However, BDNF is not pharmacokinetically optimal for use as a therapeutic agent. As a step toward the development of low-molecular-weight BDNF-like drug...
