Differences in MS patients’ cerebrospinal fluid may be key to drugs that halt progression

Posted by in categories: biotech/medical, neuroscience

The disability burden for people with multiple sclerosis (MS) can vary significantly depending on whether they have a relapsing/remitting form of the disease, where they experience periods of clinical remission, or a progressive form, where they have continued neurological deterioration without clinical remission. Effective therapies exist for managing relapsing/remitting MS, but treatment for progressive MS has proved more challenging. Now, a new paper published in the journal Brain from researchers at the Advanced Science Research Center (ASRC) at The Graduate Center, CUNY and Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai has identified potential mechanisms that may inform the development of therapies that effectively manage progressive MS.

Previous research had suggested that dysfunction of neuronal —the energy-producing subcellular organelles—occurs in the brains of MS with progressive clinical disability. However, the underlying this process remained elusive.

“Because the brain is bathed by the cerebrospinal fluid (CSF), we asked whether treating cultured neurons with the CSF from MS patients with a relapsing/remitting or a progressive disease course would possibly elicit different effects on neuronal mitochondrial function,” said the study’s primary investigator Patrizia Casaccia, Einstein Professor of Biology at The Graduate Center and founding director of the Neuroscience Initiative at the ASRC. “We detected dramatic differences in the shape of the neuronal mitochondria and their ability to produce energy. Only exposure to the CSF from progressive MS patients caused neuronal mitochondria to fuse and elongate while rendering them unable to produce energy. We therefore searched for potential mechanisms of CSF-induced neurodegeneration with the intent to define therapeutic strategies.”

Researchers create ‘epigenetic atlas’, heralding leap forward in disease diagnosis

Posted by in categories: biotech/medical, genetics

This atlas of human CoRSIVs,” they write, “provides a resource for future population-based investigations into how interindividual epigenetic variation modulates risk of disease,” and may well transform understanding of the causes of illness in the human body.


A project 370 times larger than the Human Genome Project bears first fruit. Stephen Fleischfresser reports.

Is Immortality Worth It?

Posted by in categories: biotech/medical, economics, life extension

Any major breakthrough in extending human life would drastically alter population projections. The social effects, while obviously huge, would depend on whether the years of senility were prolonged, too; whether women’s age at menopause would increase; and how families would be structured if many generations were alive at the same time. Expensive treatments to extend human lives could also have implications for inequality; as in many other areas of technology, the wealthy would be most able to afford such services.


Almost everyone would welcome an extension of their healthy lifespan, and some scientists are looking at increasingly extreme ways to achieve that. But any major breakthrough in this area could have unwanted and far-reaching demographic, social, and economic implications.

CAMBRIDGE – Humans have long sought the elixir of youth, so it is not surprising that even non-scientists closely follow the latest research into aging. But is what most people consider simply a fact of life actually a “disease” that can be cured? Or is there some insurmountable limit to the lifespan of human bodies?

Before You Take a Mail-In DNA Test, Brace Yourself for Family Secrets

Posted by in category: biotech/medical

Like many people, Barbara Greenberg wasn’t looking to unlock any deep, dark family secrets when she spit into a tube a few years ago and sent her DNA off to be analyzed. “I was just curious to see if I would find anything a bit interesting,” Greenberg says.

And at first, there were no real surprises; she was, as expected, 100 percent Eastern European Jewish. But she’d check back into her account now and then, looking for new matches to distant cousins, and eventually someone else popped up—an unknown female relative with a DNA match significant enough to indicate it was likely a half-sister.

As Greenberg and the other woman began communicating, their shared story took shape. Although the other woman had very little information about who her biological father might have been, Greenberg says the timing, location, and certain clues the woman’s mother had given over the years indicated that they did, indeed, share the same father.
