UC-Irvine Researchers Identify Substance that Can Block Alzheimer's
>

Irvine, Calif. -- Researchers at UC Irvine have found that a new compound not only relieves the cognitive symptoms of Alzheimer's disease, but also reduces the two types of brain lesions that are hallmarks of this devastating disease, thereby blocking its progression.

In a study with genetically modified mice, a team of UCI researchers led by Frank LaFerla, professor of neurobiology and behavior, found that a compound known as AF267B, developed by paper co-author Abraham Fisher of the Israel Institute for Biological Research, reduced both plaque lesions and tangles in brain regions associated with learning and memory. Although drugs exist on the market today to treat the symptoms of Alzheimer's, AF267B represents the first disease-modifying compound, meaning it appears to affect the underlying cause and reduces the two signature lesions, plaques and tangles.
