Tag: Ftl1 protein

According to a 2025 study in *Nature Aging*, the protein FTL1, also known as ferritin light chain 1, was found to be a key driver of brain aging in mice. The protein FTL1 is a subunit of the larger ferritin complex, an intracellular protein responsible for storing and releasing iron. This makes FTL1 found in nearly all cells, with its specific concentration and function varying significantly depending on the tissue and physiological conditions.

Recent research published in *Nature Aging* has identified a single protein, FTL1, as a potential driver of age-related cognitive decline in mice. This groundbreaking discovery has led many to question whether this protein is present in foods and if diet can influence its levels. However, FTL1 is not a protein consumed in the diet; it is produced within the body, specifically in the brain.
