Abstract:
In most mammalian central nervous system diseases, axons are damaged.Due to the limited ability of damaged neurons to promote axonal regeneration, the formation of glial scar and the release of inhibitory nutrients, it is difficult to regenerate axons of damaged neurons. The purpose of this study was to investigate the effect of cerebroprotein hydrolysate for injection (II) (CBL) on neuritogenesis and its underlying mechanism. Immunofluorescence staining was used to detect the axon length of mouse neuroma cells (Neuro-2a) and mouse primary cortical neuronal cells. Western blotting was used to detect the expression of phosphorylated TrkB protein in Neuro-2a cells and mouse primary cortical neuronal cells. The results showed that CBL could increase the axon length of Neuro-2a cells or mouse primary cortical neuronal cells, and that the phosphorylation level of TrkB in neuronal cells was significantly increased when 5 μg/mL CBL was applied to neuronal cells for 1 h. In conclusion, CBL can promote neuritogenesis, and increase the expression of phosphorylated TrkB, which may be related to the activation of TrkB signaling pathway.
