Cytokines and Neutrophins in Neuroprotection

submitted by: alex01
Dr. Michael Spedding published recently a review on the role of cytokines and neurotrophins in disease. Neurotrophins (e.g. BDNF) have beneficial effects on neuronal plasticity and brain metabolism. Inflammatory cytokines (e.g. IL1beta)oppose the effects of neurotrophins. Both, neurotrophins and cytokines are targets for the development of new drugs affecting central nervous system. Brain-derived neurotrophic factor (BDNF) is the main activity-dependent neurotrophic factor. Interleukin 1beta...

submitted by: video_collector
Apoptosis a form of programmed cell death that plays important roles during animal development, immune response, elimination of damaged cells, and maintenance of tissue homeostasis. Apoptosis is executed by intracellular proteases named caspases that are activated during the onset of apoptosis by extrinsic and intrinsic pathways. The intrinsic pathway is triggered by the release of proteins such as cytochrome c from mitochondria to cytosol and the extrinsic pathway is activated by the...
