The potential effect of salvianolic acid B against rat ischemic brain injury in combination with mesenchymal stem cells
Background
Mesenchymal stem cells (MSCs) and Salvianolic acid B (SAB) are known to exert potent anti-inflammatory and anti-oxidative properties. But the effect of SAB and MSCs combination treatment on the cerebral ischemia/reperfusion injury (CI/RI) is not clear.
Methods
After the CI/RI animal model established, rats were administered with MSCs and SAB individually or combination treatment. To evaluate the therapeutic potential, behavioral tests, TTC staining, Hematoxylin-eosin (HE) staining, and immunofluorescence assays were performed to evaluate the neuroprotection and endogenous neurogenesis. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining and enzyme linked immunosorbent assay (ELISA) were performed to evaluate the anti-apoptosis and anti-inflammatory effect. Meanwhile, the expression of the TLR4/NF-ĸB/MYD88 signal pathway-related proteins was evaluated by Western blot.
Results
MSCs and SAB individually or combination treatment have protective effect in CI/RI rats. More importantly, the rats with the combination treatment showed a better behavioral recovery, neurogenesis and smaller infarct size compared with the rats administered with MSCs or SAB individually. Further research showed that the combination treatment decreased CI/RI induced inflammatory cytokines and oxidative stress, including inhibiting the production of IL-1β, IL-6, TNF-α, decreasing the levels of malondialdehyde (MDA), and increased the activity of superoxide dismutase (SOD). In addition, the neuroprotection effect of SAB and MSCs combination was achieved through the regulation of TLR4/NF-κB/MyD88 signaling pathway related proteins, including inhibition the protein levels of TLR4, MYD88, p-NF-κB p65, TRAF6-and action of SIRT1 in brain tissues.
Conclusion
The present study indicated that the MSCs and SAB combination treatment had better protective effect against rat ischemic brain injury. The combination of SAB and MSCs may provide a potent and promising strategy for the treatment of ischemic stroke and is worthy for further development.
期刊介绍：
The Journal of Chemical Neuroanatomy publishes scientific reports relating the functional and biochemical aspects of the nervous system with its microanatomical organization. The scope of the journal concentrates on reports which combine microanatomical, biochemical, pharmacological and behavioural approaches.
Papers should offer original data correlating the morphology of the nervous system (the brain and spinal cord in particular) with its biochemistry. The Journal of Chemical Neuroanatomy is particularly interested in publishing important studies performed with up-to-date methodology utilizing sensitive chemical microassays, hybridoma technology, immunocytochemistry, in situ hybridization and receptor radioautography, to name a few examples.
The Journal of Chemical Neuroanatomy is the natural vehicle for integrated studies utilizing these approaches. The articles will be selected by the editorial board and invited reviewers on the basis of their excellence and potential contribution to this field of neurosciences. Both in vivo and in vitro integrated studies in chemical neuroanatomy are appropriate subjects of interest to the journal. These studies should relate only to vertebrate species with particular emphasis on the mammalian and primate nervous systems.
