The most interesting report of the week (IMHO) 🧵
New @nature.com
The possibility that lithium deficiency is a driver of Alzheimer's disease. Experimental model shows Li depletion impedes amyloid clearance, and repletion in humans could be achieved with low doses

Lithium deficiency and the onset of Alzheimer’s disease - Nature
Lithium has an essential role in the brain and is deficient early in Alzheimer’s disease, which can be recapitulated in mice and treated with a novel lithium salt that restores the physiological level.

Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses - Nature
Phagocytosed bacteria can serve as an alternative nutrient source for macrophages, influencing their metabolic and immune responses through the recycling of microbial components, with the process regulated by nutrient-sensing mechanisms and bacterial viability.
