Parkinson’s disease patients can find hope in a new treatment, thanks to stem cell research that successfully replaces damaged nerves. Swedish researchers have figured out how to create neurons that become lost in the brains of Parkinson’s disease patients. They published their findings in the journal Cell Stem Cell.

Carried out under the leadership of Malin Parmar of Lund Univerity, a member of the European consortia NeuroStemcell, the study reports an important experimental novelty in regenerative medicine strategies. This could pave the way to the clinical application of stem cells in patients with Parkinson’s Disease.

In the study, researchers took human embryonic stem cells (hESC) from in vitro fertilization embryos and grew them into motor neurons. The neurons were transplanted into the brains of rats with Parkinson’s disease, and over the course of five months, their dopamine levels rose back to normal.
The study showed that these new neurons are capable of mimicking the features of damaged neurons as well as connecting to neurons of the host brain through a dense network of branches reaching target brain areas. This discovery can open new perspectives for the future development of innovative treatments of this and other neurodegenerative diseases, including Huntington’s Disease.

In a special issue of the Cell Press journal Neuron, experts debated the challenges associated with “translational neuroscience,” and the efforts that should be made to commercialize advances made in the laboratory so that patients can benefit from them.

Despite the major advances that science is making in understanding how the human brain works, several neurodegenerative disorders and psychiatric conditions are on the rise and are becoming more frequent, outpacing diagnostic and treatment approaches.

Dr. Katja Brose, Neuron Editor, explained: “A variety of global impact studies have identified brain disorders as a leading contributor to disabilities and morbidity worldwide with a critical economic, public health, and societal impact (…) There is resounding agreement that we need new approaches and strategies, and there are active efforts, discussion, and experimentation aimed at making the process of therapeutic development more efficient and effective.”

Using data from old clinical trials, two groups of researchers have found a better way to predict how amyotrophic lateral sclerosis (ALS) progresses in different patients. The winning algorithms—designed by non-ALS experts—outperformed the judgments of a group of ALS clinicians given the same data. The advances could make it easier to test whether new drugs can slow the fatal neurodegenerative disease.

The new work was inspired by the so-called ALS Prediction Prize, a joint effort by the ALS-focused nonprofit Prize4Life and Dialogue for Reverse Engineering Assessments and Methods (DREAM), a computational biology project whose sponsors include IBM and Columbia University. Announced in 2012, the $50,000 award was designed to bring in experts from outside the ALS field to tackle the notoriously unpredictable illness.

The Medical Research Council (MRC) Dementias Research Platform UK (DPUK) is a multi-million pound public-private partnership, developed and led by the MRC, to accelerate progress in, and open up, dementias research. The DPUK’s aims are early detection, improved treatment and ultimately, prevention, of dementias.

The DPUK is creating the world’s largest population study for use in dementias research, bringing together two million participants aged 50 and over, from 22 existing study groups within the UK. Included are people from the general population, people known to be at-risk of developing dementia, and people diagnosed with early-stage dementia.

The DPUK is linking a number of industry partners with a UK-wide network of academic excellence. Six UK and international companies have signed a consortium agreement which will allow shared access to the research resources and the rich and unique data in the DPUK, and to provide a basis for instigating joint studies.

DPUK is being set up for use as a research resource for the entire scientific community. Read more at the link below.

Researchers studying frontotemporal degeneration (FTD) disease, a leading cause of early onset dementia, will receive more than $30 million over the next five years in grants from the National Institutes of Health (NIH). The funding will be used to further scientific collaboration and investigate new treatments in the quest to find a cure for FTD.

Also, in Vancouver, Canada, on October 23rd, an FTD conference demonstrated the research progress made in this awakening field, with particular emphasis on the newly forged international collaborative relationships to comprehensively examine patients and their families in longitudinal cohort studies.

In the first post on this new online service, Dr Ed Wild and Dr Jeff Carroll talk about the five new clinical trials enrolling now or starting soon for Huntington’s disease. Plus, a detailed discussion of the eagerly-awaited clinical trial of the first ‘huntingtin lowering’ drug to be tested in Huntington’s diease. Called HTT-Rx, the drug is an antisense oligonucleotide developed by Isis Pharmaceuticals Inc.

In the UK, to support clinical and care staff, managers and estates colleagues, the King’s Fund has produced a range of resources to enable hospitals, care homes, primary care premises and specialist housing providers to become more dementia friendly.

The work that informed the initial development of the resources, the EHE dementia care programme, was funded by the Department of Health to support the implementation of the National Dementia Strategy and the Prime Minister’s ‘Challenge on Dementia’.

The EHE programme is designed to improve the environment of care for people with dementia. It involved 23 teams from acute, community and mental health NHS trusts who worked on a range of projects across the dementia care pathway and sought to make hospital environments less alienating for people with cognitive problems. Projects have demonstrated that relatively inexpensive interventions, such as changes to lighting, floor coverings and improved way-finding, can have a significant impact. Evaluation has shown that environmental improvements can have a positive effect on reducing falls, violent and aggressive behaviours, and improving staff recruitment and retention. The EHE schemes are already showing that it is possible to improve the quality and outcomes of care for people with dementia as well as improve staff morale and reduce overall costs by making inexpensive changes to the environment of care.

The King’s Fund has also published on Sept. 4th 2014, the final report of the Commission on the Future of the Health and Social Care in England (the Barker report).  “A New Settlement for Health and Social Care, relations between health and social services”, makes a plea for “better integration” and warns of “hard choices” ahead.

The 2014 Nobel Prize in Physiology or Medicine has honored three neuroscientists.

John O’Keefe, along with May-Britt Moser and Edvard Moser, discovered cells that form a positioning system in the brain — our hard-wired GPS. Those cells mark our position, navigate where we’re going and help us remember it all, so that we can repeat our trips, the Nobel Assembly said in a statement.

Their research could also prove useful in Alzheimer’s research, because of the parts of the brain those cells lie in — the hippocampus and the entorhinal cortex.

Humans and other mammals have two hippocampi, which lie in the inner core of the bottom of the brain and are responsible for memory and orientation. The entorhinal cortices share these functions and connect the hippocampi with the huge neocortex, the bulk of our gray matter.

In Alzheimer’s patients, those two brain components break down early on, causing sufferers to get lost more easily. Understanding how the brain’s GPS works may help scientists in the future understand how this disorientation occurs.

The research is also important, because it pinpoints “a cellular basis for higher cognitive function,” the Nobel Assembly said.

The scientists conducted their research on rats, but other research on humans indicates that we have these same cells.

A Small Number of Patients With Fetal-Cell Transplants Are Thriving Two Decades Later.

Several patients with Parkinson’s disease who received brain-tissue transplants from fetuses in the early 1990s have needed little or no medicine to treat the disease ever since—an outcome virtually unheard of in the course of the disease, researchers have found.

The results are particularly striking because the treatment is controversial and has been questioned by some researchers in the field.

Bolstered by these promising cases, 14 European hospitals, research institutions and companies have launched a new, controversial trial on fetal-cell transplants, known as Transeuro. Funded with a $15 million grant by the European Union, surgeons in Cambridge, England, are expected to perform their first transplant on a trial participant by year’s end. It would be the first since the 1990s.
