We have previously reported that folic acid potentiated effects of Alzheimer’s disease (AD) drug on neuronal protection in early-stage AD development. Folic acid is a kind of nutrient supplement, and folinic acid is a clinical cancer drug. However, in this study, the treatment of late-stage AD with folate derivatives in 3xTg-AD transgenic mice was investigated. Forty 3xTg-AD mice at 16 month-old were divided into three groups fed with the diet in the absence (Control) or presence of folic acid (FA) and folinic acid (FN) supplements (12 mg/kg/day by force feeding). Spatial memory function was assayed by water-maze test before mice were sacrificed at 19 month-old. The data revealed that FA and FN groups had significantly higher levels of serum folate than the controls group after 3 month supplementation (p<0.05). The AD neuropathological markers of Aβ40, Aβ42 or phosphotau levels were significantly lower in the brains of FA and FN groups as compared with the controls (p<0.05). Although these reduced brain pathological severity by FA or FN supplement were not associated with cognition improvement, survival rates of FA (69%) and FN groups (86%) was 1.6 fold-increased in relative to the controls (54%) at 19 month-old. Taken together, the data demonstrated that FA and FN treatments may alleviate pathological severity of late-stage Alzheimer’s disease associated with increased survival rate of 3xTg-AD mice.
