Researchers found that cells with damaged DNA trigger a mechanism to signal natural killer cells, which attack and destroy cancerous cells. The immune system's ability to identify cancer cells is crucial in preventing tumor growth.
Researchers have discovered that an experimental drug can reverse the loss of nerve fibres in Parkinson's Disease. The study found that dopamine-containing nerve fibres had sprouted back in the brain, leading to improved motor function and sustained benefits even after treatment cessation.
The study reveals key connections between metabolic disease pathways and aging, identifying genes and mechanisms that can be targeted for drug discovery. Targeting these pathways may uncover novel therapeutic targets and drugs to treat metabolic diseases and potentially impact the progression of aging.
