A Population Study Correlates Air Pollution with Faster Cognitive Aging
https://www.fightaging.org/archives/2024/04/a-population-study-correlates-air-pollution-with-faster-cognitive-aging/
A number of large epidemiological studies provide evidence for long-term exposure to greater levels of air pollution to accelerate the onset and progression of age-related disease. A few of these manage to control for the tendency for wealthier people to avoid living in areas with higher particulate air pollution, ...

Herpes Simplex Infection Correlates with Amyloid Burden in the Aging Brain
There is a continuing debate over the degree to which Alzheimer's is driven by persistent infection in brain tissue, such as by varieties of herpesvirus. Amyloid-β is an antimicrobial peptide, a part of the innate immune response, and one could argue that persistently raised expression of amyloid-β will increase misfolding and generation of the aggregates that drive pathology in the early stages of Alzheimer's disease, at least under the amyloid cascade hypothesis. The data is not all convincing, however, which suggests that perhaps there are other factors involved - that multiple viruses interact in some people, for exa...

Does Herpes Simplex Virus cause Alzheimer ’ s Disease?
by Gertrud U. Rey Alzheimer’s Disease (AD) is a neurodegenerative disorder and the most common form of dementia. Although its exact cause is unclear, an increasing body of evidence suggests that an infection with herpes simplex virus (HSV) may contribute to onset of AD later in life. Both types of HSV (HSV-1 and HSV-2) infect … Does Herpes Simplex Virus cause Alzheimer’s Disease? Read More » (Source: virology blog)

A Way in Which Mitochondrial DNA Becomes Misplaced, Provoking Inflammation
Cells respond to the presence of DNA in the cytoplasm with inflammatory signaling, an evolved innate immune response that serves to protect against viral and bacterial infection. This becomes a problem when mitochondria become dysfunctional, as mitochondria contain their own small genome, the mitochondrial DNA. In the context of age-related mitochondrial dysfunction, and a number of other circumstances, fragments of mitochondrial DNA can find their way into the cell cytoplasm. The result is a link between mitochondrial dysfunction and the chronic inflammation of aging, though it remains unclear as to how much of this chara...

Increased Dietary Leucine Activates mTOR Signaling in Macrophages, Accelerating Atherosclerosis

Leucine is an essential amino acid, only obtained from the diet rather than synthesized by our cells. Leucine supplementation has been proposed as a way to slow the loss of muscle mass with age, as leucine processing becomes dysregulated with aging in a way...

A Look Back at 2023: Progress Towards the Treatment of Aging as a Medical Condition
The market has been in the doldrums and it has been a tough year for fundraising, both for non-profits and biotech startups. The conferences have exhibited more of an academic focus as companies tightened belts and postponed investment rounds, while investors stayed home. Not that this halts the flow of hype for some projects, and nor has it slowed media commentary on the longevity industry as it presently stands. A few of the articles in that commmentary are even interesting to read! The field has grown and is more mature now than has ever been the case. Biotech of all forms is a challenging field with a high failure rate...

More Evidence for Vaccination to Reduce Alzheimer's Disease Risk
There is good evidence for the various forms of later life vaccination, such as for herpes zoster or influenza, to reduce the risk of later suffering Alzheimer's disease. One possibility is that people who take the time to obtain a vaccine tend to take better care of their health across the board. Another possibility is that vaccination produces a trained immunity effect that dampens age-related inflammation for a sustained period of time. It may also be the case that suffering from influenza, pneumonia, or similar infectious diseases causes sufficient additional inflammation to move the odds on suffering later neurodegene...

MedEssist is Helping to Transform Pharmacies into Pharmacy Health Clinics
The healthcare system in many countries is stretched thin. To help relieve the pressure, governments are starting to allow pharmacists to treat a growing number of minor ailments. MedEssist’s technology platform is helping pharmacies transform into health clinics.
Healthcare IT Today got a brief demonstration of the MedEssist platform from Joella Almeida, CEO and Co-Founder at the Collision Conference. We also asked her about the expanding role of pharmacists in healthcare.
Pharmacies Are Already in the Community
“We are focused on helping independent pharmacies,” explained Almeida. “There’s one on every bloc...

Herpes Zoster Vaccination Reduces Alzheimer's Risk
Evidence exists for herpesvirus infection to increase the risk of suffering Alzheimer's disease. The evidence is mixed, however, with some studies showing no effect. There is some suggestion that the interaction of multiple viruses is the real contributing effect, which is why looking at just one virus type may produce problematic data. Researchers here show that vaccination against herpes zoster reduces Alzheimer's risk, though one might as to whether this is because of reduced viral impact, or because vaccinations can produce a trained immunity effect, reducing chronic inflammation in older people.
There is grow...
