We also observed significantly lower lactate, an energy metabolite produced in astrocytes from glucose
A small number of real human trials have found a topical glutathione lotion: The honest caveat is that the current evidence is still thin (few studies, small groups, short timelines)
While ROS play important roles in redox signaling and defense mechanisms, their excessive accumulation can disrupt the delicate balance of redox potential within cells, leading to oxidative stress and cell damage
Another AD study, focused on targeting CD38, showed that CD38 knockdown in APP Swe mutation-expressing transgenic mice enhanced NAD + levels and reduced A plaques in brain extracts, mirrored by some improvement of cognitive performance 270,274
However, such specialization might limit adaptability to new biotic challenges, as seen in evolutionary studies linking GPX regulation to altered ROS signaling and pathogen interactions
