"These researchers found evidence of what they called "tanycytic degradation in the hypothalamus" in patients with Alzheimer's. In other words, tancytes in the brain correlated with the presence of Alzheimer's disease. That raises the question of whether this degradation is a cause or a symptom of the disease in question."
"As Vincent Prévot of the French National Institute of Health and Medical Research - and one of the paper's authors - told Nature's Rachel Fieldhouse, he and his colleagues did not observe tanycytic degradation in brain tissue samples taken from people without Alzheimer's disease."
"As one of the experts who spoke to Nature pointed out, among the lines of inquiry that could follow from this is a significant one: is there a way to bolster tancytes in the brain using medication? The answer could have massive consequences."
Researchers investigating Alzheimer's disease have identified tanycytes, specialized brain cells known as "neuron whisperers," as key players in tau protein transport and removal from the brain. A recent study published in Cell Press Blue found evidence of tanycytic degradation in the hypothalamus of Alzheimer's patients, a phenomenon not observed in healthy individuals. This discovery raises important questions about whether this cellular degradation causes or results from Alzheimer's disease. The findings suggest potential therapeutic avenues, particularly whether medications could strengthen tanycytes to improve tau protein clearance and potentially prevent or slow disease progression.
