Enriched environment promotes post-stroke neurogenesis through NF-κB-mediated secretion of IL-17A from astrocytes.
Enriched environment (EE) has been shown to promote post-stroke neurogenesis and functional recovery. However, the underlying molecular mechanisms remains poorly understood. Male C57BL/6 mice underwent 60-min middle cerebral artery occlusion (MCAO) followed by reperfusion, after which mice were housed in either standard environment (SE) or EE. We found that post-ischemic EE exhibited reduced protein level of nuclear factor κB (NF-κB)/p65 in cytoplasm and increased its expression correspondingly in nucleus at 28 days post-ischemia (dpi). However, post-ischemic EE had no effects on terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling (TUNEL)-positive cells in ischemic hemisphere at 28dpi. EE mice treated with NF-kB inhibitor Bay11-7082 had decreased subventricular zone (SVZ) neural precursor cells (NPCs) proliferation, neuronal differentiation and subsequent functional recovery after stroke at 28dpi. Bay11-7082 treatment attenuated the promoting effects of post-ischemic EE on interleukin 17A (IL-17A) messenger RNA (mRNA) and protein expression at 28dpi. Furthermore, our in vitro data revealed that in primary astrocyte cultures addition of Bay11-7082 markedly decreased the expression of IL-17A in both the cell lysate and culture supernatant of activated astrocytes. Blockade of IL-17A with neutralizing antibody abrogated the promoting role of EE in NPCs proliferation derived from SVZ, neuronal differentiation and subsequent functional recovery after stroke. Thus, our results reveal a previously uncharacterized property of NF-κB/IL-17A signaling pathway in EE-mediated neurogenesis and functional recovery after ischemic stroke.Yujing Zhang, Dan Xu, Hong Qi, Yin Yuan, Hong Liu, Shanglong Yao, Shiying Yuan, Jiancheng Zhang
