For decades, the medical community viewed neuroinflammation as the “enemy”—a destructive byproduct of diseases like Alzheimer’s and Parkinson’s that needed to be suppressed at all costs. However, a sweeping review published in the Journal of Clinical Investigation reveals a far more nuanced reality: the brain’s immune system is not merely a passenger in neurodegeneration, but … Read more
For decades, the war against Alzheimer’s disease has been fought on a single front: the aggressive removal of amyloid-β plaques. However, after a string of modest results from drugs targeting these proteins directly, the scientific community is pivoting. The focus is shifting from the “trash” (plaques) to the “janitors”—the microglia—and a new study suggests we … Read more
Brain’s Immune Response: A Common Thread in Neurological Diseases and Potential New Therapies Recent research is revealing surprising similarities in how the brain’s immune system reacts across a range of debilitating conditions, from Alzheimer’s disease and multiple sclerosis to brain tumors. This discovery is not only deepening our understanding of these complex illnesses but also … Read more
A potential turning point in the fight against Parkinson’s disease has emerged from research at the Institut de Neurociències of the UAB. Scientists have identified a key mechanism driving the loss of dopamine-producing neurons – the hallmark of the disease – and, crucially, demonstrated that immunotherapy could offer a protective effect. This isn’t just another … Read more
Nearly 70% of adults report experiencing some form of unwanted intrusive memories. But what if we could selectively ‘reset’ those memories, or even enhance the retention of crucial experiences? Emerging research suggests the key lies not in the neurons themselves, but in the brain’s often-overlooked immune cells – microglia – and their surprising influence on … Read more
The persistent shadow of negative emotions following heavy drinking – a key driver of Alcohol Use Disorder (AUD) – isn’t simply a psychological effect, but a deeply rooted biological process driven by inflammation in the brain. New research published in The American Journal of Pathology pinpoints microglia, the brain’s resident immune cells, as central to … Read more
