(Press-News.org) New Rochelle, NY, October 9, 2013—Cancer immunotherapy can successfully use the body's own immune system to kill tumor cells. But some current approaches to stimulate an antitumor immune response are short-lived, with limited clinical effectiveness. A new gene transfer strategy that introduces modified, immune-stimulating human stem cells is both feasible and effective for achieving persistent immunotherapy to treat leukemias and lymophomas, according to a study published in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Human Gene Therapy website.
Satiro Nakamura De Oliveira and coauthors from the David Geffen School of Medicine, University of California, Los Angeles and University of Texas MD Anderson Cancer Center, Houston, describe the gene transfer method they developed to deliver chimeric antigen receptors, or CARS, that direct the immune system to target tumor cells derived from B-lymphocytes.
In the article "Modification of Hematopoietic Stem/Progenitor Cells with CD19-specific Chimeric Antigen Receptors as a Novel Approach for Cancer Immunotherapy" the authors show that by packaging the CARS in human hematopoietic stem cells, the immunotherapeutic receptors will be produced in the bloodstream for a long period of time. This persistent expression should improve their effectiveness in the treatment of blood cancers such as leukemia and lymphoma.
"This study represents an interesting new direction for an approach that has generated substantial interest," says Dr. Wilson, Director of the Gene Therapy Program, Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine, Philadelphia.

Multivitamins with minerals may protect older women with invasive breast cancer
2013-10-09
October 9, 2013 — (BRONX, NY) — Findings from a study involving thousands of postmenopausal women suggest that women who develop invasive breast cancer may benefit from taking supplements containing both multivitamins and minerals. The new research, published today in Breast Cancer Research and Treatment, found that the risk of dying from invasive breast cancer was 30 percent lower among multivitamin/mineral users compared with nonusers.
"Our study offers tentative but intriguing evidence that multivitamin/mineral supplements may help older women who develop invasive ...
When it comes to the good cholesterol, fitness trumps weight
2013-10-09
Bethesda, Md. (Oct. 9, 2013)—There's no question that high levels of good cholesterol—also known as high-density lipoprotein (HDL)—seem to be protective against heart disease. Rather than depositing fat into the blood vessels the way the "bad" cholesterol (low-density lipoprotein (LDL)) does, HDL appears to carry cholesterol away from blood vessels to the liver. From there, the liver processes it for removal from the body.
However, adequate levels of HDL might not be enough. Several recent studies have suggested that many cases of heart disease occur in people with ...
Football players suffer more injuries when their team is ahead
2013-10-09
Male football players are at a greater risk of injury five minutes after a card has been given or after a goal has been scored. The frequency of player injuries also increases when their own team is in the lead. These are the findings of researchers at the Sahlgrenska Academy, who, in collaboration with Fifa, have analysed injuries over the last three World Cup tournaments.
Football players do not just injure themselves whenever and however. On the contrary, injury frequency follows a clear pattern that is dependent on how various events in the course of a match affect ...
Sleeping in on the weekends doesn't fix all the deficits caused by workweek sleep loss
2013-10-09
Bethesda, Md. (Oct. 9, 2013)— In many modern societies, adults often sacrifice sleep during the workweek to make time for other demands, then snooze longer on the weekends to recoup that lost sleep. Research has shown that even a few days of lost sleep can have adverse effects, including increased daytime sleepiness, worsened daytime performance, an increase in molecules that are a sign of inflammation in the body, and impaired blood sugar regulation. These last two could be partially responsible for why sleeping less negatively affects health in other ways and shortens ...
Notre Dame researchers make progress toward a treatment for dangerous allergies
2013-10-09
New research published in the journal Nature Chemical Biology shows that a group of scientists, led by faculty at the University of Notre Dame, has made concrete progress toward the development of the first-ever inhibitory therapeutic for Type I hypersensitive allergic reactions.
"Our allergy inhibition project is innovative and significant because we brought a novel molecular design approach to selectively inhibit mast cell degranulation — the key event in triggering a food allergic response — which has the potential to improve the quality of life for affected patients," ...
Recombinant human prion protein inhibits prion propagation
2013-10-09
Case Western Reserve University researchers today published findings that point to a promising discovery for the treatment and prevention of prion diseases, rare neurodegenerative disorders that are always fatal. The researchers discovered that recombinant human prion protein stops the propagation of prions, the infectious pathogens that cause the diseases.
"This is the very first time recombinant protein has been shown to inhibit diseased human prions," said Wen-Quan Zou, MD, PhD, senior author of the study and associate professor of pathology and neurology at Case Western ...
Water and lava, but -- curiously -- no explosion
2013-10-09
BUFFALO, N.Y. — Rocky pillars dotting Iceland's Skaelingar valley were projectiles tossed into the fields by warring trolls. That, at least, is the tale that University at Buffalo geologist Tracy Gregg heard from a tour guide and local hiker when she visited the site on two occasions.
But Gregg and a colleague have a new explanation for the presence of the lava formations — this one also unexpected.
In the Journal of Volcanology and Geothermal Research, she and former UB master's student Kenneth Christle report that the pillars, hollow and made from basalt, likely formed ...
An experiment puts auditing under scrutiny
2013-10-09
CAMBRIDGE, MA -- The structure of the auditing business appears problematic: Typically, major companies pay auditors to examine their books under the so-called "third-party" audit system. But when an auditing firm's revenues come directly from its clients, the auditors have an incentive not to deliver bad news to them.
So: Does this arrangement affect the actual performance of auditors?
In an eye-opening experiment involving roughly 500 industrial plants in the state of Gujarat, in western India, changing the auditing system has indeed produced dramatically different ...
Poetry is like music to the mind, scientists prove
2013-10-09
New brain imaging technology is helping researchers to bridge the gap between art and science by mapping the different ways in which the brain responds to poetry and prose.
Scientists at the University of Exeter used state-of-the-art functional magnetic resonance imaging (fMRI) technology, which allows them to visualise which parts of the brain are activated to process various activities. No one had previously looked specifically at the differing responses in the brain to poetry and prose.
In research published in the Journal of Consciousness Studies, the team found ...
New research refutes claim that mummified head belonged to King Henry IV of France
2013-10-09
Two purportedly royal relics recently surfaced on the collectors' market in France: a mummified head and a handkerchief with blood residues. The head was said to be that of French king Henry IV and the blood on the handkerchief that of King Louis XVI. This was confirmed by Spanish and French researchers, who reported positive DNA matches. Several historians voiced doubts about these claims and enrolled the help of forensic identification specialist Professor Jean-Jacques Cassiman and his team to investigate the relics.
Professor Cassiman's team compared the published ...
