Gene deletion and gene knock-out can restrain acid-induced neuronal injury. The transfection of the gene would, however, rebuild its sensitivity.  Studies have shown that in animals' brain tissues ,which are free of damage,  reduction of the PH value to 6.5 or the ischemia will not cause injury.  But ischemia and acid, when combined together, would cause intoxication and greatly increase toxic effects , which will result in obvious brain damage.

When the gene knockout or inhibits acid when induced neurons damage, but the genes and transfection rebuilding its sensitivity. Studies have shown that, in the intact animals in the brain, only lower PH value to 6.5 or ischemic damage, but will not cause ischemic merger acidosis, when can significantly increase but the toxic effects, resulting in significantly brain damage

When there is gene deletion or knockout, the acid-induced neuronal damage can be inhibited. The transfection of the gene would, however, rebuild its sensitivity. Studies have shown that in healthy animal brain tissues, neither decrease of the PH value to 6.5 nor ischemia alone causes any danage. But when ischemia and excessive acid are combined together, the toxicity would significantly increase, which results in obvious brain damage.
