Immune cells commonly blamed in Alzheimer’s and other neurodegenerative diseases are actually precision cleaning machines protecting the central nervous system, new research from the UVA School of Medicine shows. The discovery adds nuance and complexity to our understanding of immune cells known as microglia. By appreciating the role of these cells in full, scientists are better positioned to develop new treatments and tailor medicine to individual patients’ needs. “What we’re finding now is that at very acute time points, whether it’s in disease or whether it’s injury, the microglia are doing a lot,” said researcher Geoffrey Norris, PhD. “It’s important to know the role and function of these cells, especially going forward for human therapy.”.......To Read More....
There's more in Science Daily: Missing link found between brain, immune system; major disease implications . In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist. That such vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the body is surprising on its own, but the true significance of the discovery lies in the effects it could have on the study and treatment of neurological diseases ranging from autism to Alzheimer's disease to multiple sclerosis...........
My Take - I've posted these because we occasionally see weasel word claims that pesticides "may" contribute to Alzheimer's disease over a life time. This article demonstrates one incontrovertible fact. What we know for sure is far more limited than we may believe, and certainly not enough to make speculative claims against pesticides.
