Alzheimer’s Disease successfully reversed in mice!

alzheimer's freeThe incidence of Alzheimer’s Disease is increasing, and it’s projected that by the year 2050, the number of people with Alzheimer’s could triple. But new research could change that: researchers have discovered a drug compound that has successfully reversed the effects of Alzheimer’s disease in mice! After just one dose of this compound, called TC-2153, mice with Alzheimer’s were able to learn just as well as healthy mice!

Here’s how they figured it out: the protein STEP (STriatal-Enriched tyrosine Phosphatase) attacks neurotransmitters in the brain and prevents patients with Alzheimer’s from learning and retaining new information. STEP levels are often elevated in patients with Alzheimer’s and Parkinson’s Disease. Knowing this, researchers turned to mice for help. They previously found that when Alzheimer’s mouse models (mice that are genetically engineered to develop the disease) had lowered levels of STEP, their cognitive abilities were similar to those of unaffected mice. The problem is that researchers could genetically lower STEP levels in mice- but you can’t do that in humans.

The understanding of STEP’s role in the disease led researchers to search for different compounds that could block it. And it appears that they’ve succeeded! More research is certainly needed to determine whether or not TC-2153 will work in other animals, and possibly humans, but the identification of this STEP-inhibiting compound is certainly good news!
