Previous studies have shown that most brain DHA is manufactured in the liver. Earlier work had found that one strain was protected against the buildup of beta amyloid in the brain, compared with the other. The research team identified three genes that could confer such protection. They showed that cells in the liver of the protected mice did not express, or turn on, these genes, as much as liver cells of the other mice.

The researchpublished June 21 in Neuron, found convincing signs that certain types of herpes virus may promote the complex process that leads to the disease that afflicts some 5.

The long-standing amyloid hypothesis posits that symptoms are triggered by the buildup of amyloid beta brain plaques, but trials of drugs that attempt to clear these plaques have so far flopped.

Skeptical researchers have hunted for other explanations, and some have zeroed in on microbes. Joel Dudley, a geneticist and genomic scientist at the Icahn School of Medicine at Mount Alzheimers disease research papers and senior author of the new paper, had not intended to investigate this theory when his lab began working on the newly published study in HHV-6A is a usually symptom-less virus that infects people later in life.

HHV-7 infects more than 80 percent of infants, often causing a rash. To probe this question, the team created the equivalent of a biological social network to probe how various molecular and genetic signals were interacting with each other.

When they later bred mice deficient in this microRNA, they found that the rodents developed larger and more abundant amyloid plaques in their brains than did mice with normal microRNA levels. The new findings do not prove that the viruses cause the onset or contribute to the progression of Alzheimer's disease.

It might be possible to use certain biological markers of the viruses to identify high-risk individuals. A series of studies led by Massachusetts General Hospital neurologist Robert Moir and colleagues suggests a possible theory to bind these disparate pathogen findings together: Beta amyloid proteins may accumulate in the brain as part of an immune response against injury or invading pathogens.

In a paper published online on June 21st, also in Neuron, Moir and colleagues reported that amyloid beta peptides bind to and entrap HSV-1 and HHV-6, thereby helping to protect against infection. Mice infected with these herpes viruses quickly accumulate beta amyloid plaques, too.

Their theory posits that when enough beta amyloid plaques build up during an infection, they then trigger inflammation and other unhelpful responses, such as the creation of tau tangles that kill neurons.

The plaques also alert brain immune cells called microglia to the fact that something is wrong; these cells launch an immune cascade that kills even more neurons. Strengthening the evidence for this controversial idea will be difficult.

Academic Papers: Alzheimer's Disease Research Paper So in May of that year, when a batch of new results provided the strongest evidence he had yet seen for his theory, he wanted to be excited, but instead felt nervous.

According to Hugh Fudenberg, MD, the world's leading immunogeneticist and 13th most quoted biologist of our times (nearly papers in peer review journals): If an individual has had 5 consecutive flu shots between and (the years studied) his/her chances of getting Alzheimer's Disease is 10 times higher than if he/she had one, 2 or no shots.
