PET reveals inflammatory cycle in the brain

Molecular imaging tracks an immune response tied to neurodegenerative disease Neuroinflammation caused by a reactive immune system could be tripping off the neurodegeneration seen in certain dementias, multiple sclerosis, and other deadly diseases of the nervous system. A novel molecular imaging technique could be the key to understanding how best to treat these and other [...]

Anavex encouraged by data showing sigma-1 receptor reduces tau dysfunction, a hallmark of Alzheimer’s disease

Anavex Life Sciences Corp, a clinical-stage biopharmaceutical company developing drug candidates to treat Alzheimer’s disease, other central nervous system (CNS) diseases, pain, and various types of cancer, is encouraged by recent data published in the Proceedings of the National Academy of Sciences. The research determines that activating the sigma-1 receptor with agonists can potentially reduce [...]

Blood to feeling: McMaster scientists turn blood into neural cells

Adult sensory neurons made from human patients blood sample Scientists at McMaster University have discovered how to make adult sensory neurons from human patients simply by having them roll up their sleeve and providing a blood sample. Specifically, stem cell scientists at McMaster can now directly convert adult human blood cells to both central nervous [...]

Study shows role of disease-fighting cells in HIV-related neurological damage

Findings add to evidence that macrophage accumulation is central to brain injury Despite symptom-stifling anti-retroviral drugs, as many as half of all patients living with HIV experience neurological damage tied to chronic inflammation in the brain fueled by the body’s own immune defenses. In an effort to understand why patients who appear virus free are [...]
