The All New Vaccine Will Eliminate HPV Infection, Claims Study

Harper also noted TS is different from Gardasil9, the vaccine given to prevent HPV infection. While Gardasil9 prevents HPV infection from occurring, TS clears tissue infected with it.

While "the surgical procedure removes all the tissue that is headed towards cancer, it does not remove all the HPV. You still have HPV", Harper said, adding the new vaccine "actually treats the cause of the disease, which is HPV". VOA

A new experimental immune-based vaccine has cleared human papillomavirus (HPV) in a third of women with cervical cancer precursors, according to clinical trial results.

The therapeutic vaccine, called Tipapkinogen Sovacivec (TS), injects a specific protein that triggers an immune system response to attack high-risk HPV types that cause nearly all cervical cancer precursors, known as cervical intraepithelial neoplasia (CIN).

HPV is a common sexually transmitted infection and causes warts in the body.

The vaccine eliminated both precancerous skin growth in the cervix, and underlying HPV infection in a third of women enrolled in the clinical trial, according to the report in the journal Gynecologic Oncology.

“There are few products trying to cure women with an HPV infection,” said Diane Harper, professor at the University of Michigan. “It’s exciting. This is the first time we’ve seen something with this success rate and that is relatively easy to implement,” Harper said.

The study enrolled 192 women, diagnosed with precancerous skin growths, randomising 129 to receive the vaccine and 63, placebo.

Women were given three shots in thighs, one per week. Six months later, the women were treated with standard surgical procedures and the removed tissue was examined. As many as 15-36 per cent of those who were vaccinated saw their more severe precancerous skin growths eliminated, but none in the placebo group.

The researchers envision testing TS for several other types of cancer, including head, neck and anal cancer, that are linked to HPV. (IANS)

Parkinson Treatment Possible Through A Blood Pressure Drug

Felodipine was effective at reducing the build-up of "aggregates" in mice with the Huntington's and Parkinson's disease mutations and in the zebrafish dementia model.

"This is the first time that we're aware of that a study has shown that an approved drug can slow the build-up of harmful proteins in the brains of mice using doses aiming to mimic the concentrations of the drug seen in humans," said Professor Rubinsztein. Pixabay

Felodipine, a prescribed drug to treat high blood pressure, has shown promise against Parkinson’s, Huntington’s and forms of dementia in studies carried out in mice and zebrafish at the University of Cambridge.

In a study published in the journal Nature Communications, scientists have shown in mice that felodipine may be a candidate for re-purposing.

A common feature of neurodegenerative diseases is the build-up of misfolded proteins.

These proteins, such as huntingtin in Huntington’s disease and tau in some dementias, form “aggregates” that can cause irreversible damage to nerve cells in the brain.

A team led by Professor David Rubinsztein used mice that had been genetically modified to express mutations that cause Huntington’s disease or a form of Parkinson’s disease, and zebrafish that model a form of dementia.

Felodipine was effective at reducing the build-up of “aggregates” in mice with the Huntington’s and Parkinson’s disease mutations and in the zebrafish dementia model.

The treated animals also showed fewer signs of the diseases.

“This is the first time that we’re aware of that a study has shown that an approved drug can slow the build-up of harmful proteins in the brains of mice using doses aiming to mimic the concentrations of the drug seen in humans,” said Professor Rubinsztein.

In healthy individuals, the body uses a mechanism to prevent the build-up of such toxic materials.

This mechanism is known as autophagy, or ‘self-eating’, and involves cells eating and breaking down the materials.

“This is only the first stage, though. The drug will need to be tested in patients to see if it has the same effects in humans as it does in mice. We need to be cautious, but I would like to say we can be cautiously optimistic,” said Professor Rubinsztein. (IANS)
