Although no one is announcing a cure for Alzheimer’s disease just yet, research recently conducted at the University of Southern California does at least offer a glimmer of hope. Using drugs known as TSPO (translocator protein) ligands, scientists there have successfully halted and even reversed the effects of Alzheimer’s in mice.
The mice, all of which were male, had been genetically engineered to develop the disease. The drugs were tested on both 7-month-old young adult mice and 24-month-old elderly mice. Because the TSPO ligands increase production of steroid hormones, it was important that the animals’ existing testosterone levels be kept low before beginning the treatment. While this had already occurred naturally with the older mice as a result of aging, the younger ones had to be castrated in order to bring their levels down.
