    Drug Compound Halts Alzheimer’s-related damage in Mice

    January 26, 2017, Categories  Biology/Biotechnology, Health/Medical

    In some people, the brain protein tau collects into toxic tangles that damage brain cells and contribute to diseases such as Alzheimer's. Researchers at Washington University School of Medicine in St. Louis have found a drug that can lower tau levels and prevent some neurological damage. In neurons that contain the drug (above, in red) there are no tau tangles (in green). Credit: Sarah DeVos

    Appears to reverse some neurological harm. Under ordinary circumstances, the protein tau contributes to the normal, healthy functioning of brain neurons. In some people, though, it collects into toxic tangles that damage brain cells. Such tangles are a hallmark of Alzheimer’s and other neurodegenerative diseases. But researchers at Washington University School of Medicine in St...

    Early Abnormalities of Alzheimer’s disease: It takes 2 proteins to tango

    April 20, 2016, Categories  Biology/Biotechnology, Health/Medical

    Synergistic effect between [18F]florbetapir SUVR and CSF p-tau drives [18F]FDG uptake decline in limbic regions. Statistical parametric maps, after correcting for multiple comparisons (false discovery rate corrected at P<0.001), overlaid in a structural MRI scan, reveal areas in which 24-month [18F]FDG uptake decline occurs as a function of the synergistic interaction between baseline [18F]florbetapir SUVR and CSF p-tau measurements. Significant interactive effects were observed in the basal and mesial temporal, orbitofrontal, and anterior and posterior cingulate cortices. The analysis was corrected for age, gender and APOE ε4 status. CSF, cerebrospinal fluid; [18F]FDG, [18F]fluorodeoxyglucose; MRI, magnetic resonance imaging; p-tau, phosphorylated tau; SUVR, standardized uptake value ratio.
