However, the bodys ability to convert these building blocks can be affected by age, stress, and overall metabolic health
de Paiva IHR, da Silva RS, Mendona IP et al (2023) Fructooligosaccharide (FOS) and Galactooligosaccharide (GOS) improve Neuroinflammation and Cognition by Up-regulating IRS/PI3K/AKT signaling pathway in Diet-induced obese mice
Metal ion imbalance and oxidative stress trigger the overproduction of A by activating - or -secretases and inhibiting -secretase, and also cause tau hyperphosphorylation by activating protein kinases, such as glycogen synthase kinase-3 (GSK-3), cyclin-dependent protein kinase-5 and MAPKs, and inhibiting protein phosphatase 2A (Wang et al., 2020)
Additionally, both low and high doses of taurine (100 and 400 mg/kg via oral gavage) over nine weeks increased GSH in brain homogenates of mice exposed to D-galactose (22) and improved cognitive deficits in the aging model used in that study
