Long-term potentiation (LTP), discovered in the 1970s, was later shown to be the molecular basis of memory. Since many diseases of aging affect memory, could memory formation and storage be altered by the same mechanisms in normal aging and diseased

Early on, researchers had learned that the hippocampus was the structure in the brain where long-term memories were created and stored, but it was not known whether the different cell types within this structure might be more or less susceptible to t
The initiating cause of Alzheimer’s disease is still unknown. However, from our studies it’s clear that many types of neuronal damage—from traumatic brain injury, to epilepsy, infection, or genetic predisposition—can activate brain immune cells—
While gut microbiota appear to have both positive and negative impacts on our health, in the guts of healthy, lean individuals, the good outweighs the bad. Gut bacteria, most of which reside in the large intestine, process many otherwise indigest
Gut bacteria that feed on healthy food appear to amplify the nutritional benefits of those foods. However, they also appear to amplify the undesirable effects of unhealthy food. Here are a few examples. Read the full story.
Like other enveloped viruses, HIV exits its host cell enshrouded in the cell’s membrane, which contains membrane molecules such as the human leukocyte antigens (HLA). The HLA proteins act as a set of cell identification marks: every person expresses
The hallmark pathology of Parkinson’s disease is the damage and death of dopamine producing neurons in the brain. Dopamine plays a role in controlling movement, cognition, learning, and mood, explaining the dementia and difficulty with motor control
