New genetic resource to accelerate development of novel treatments for diseases

A new genetic resource from an international research consortium is expected to accelerate the development of new cures and treatments for a wide range of human diseases. This project, called the mouse "Collaborative Cross" (CC) resource, will increase the likelihood that experiments conducted in mice will advance our understanding of human biology.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

Scientists test new 'therapeutic vaccine' against HIV on volunteers

Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were so to say vaccinated with their own cells.

SAMHD1 protein cuts off raw material that HIV needs to create DNA and replicate

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

PRP therapy shows promise against elbow injuries

As elbow injuries continue to rise, especially in pitchers, procedures to help treat and get players back in the game quickly have been difficult to come by. However, a newer treatment called platelet rich plasma (PRP) may pose hope, according to researchers presenting their findings at the American Orthopaedic Society for Sports Medicine's Specialty Day meeting in San Francisco.

Conventional method has minimal role in determination of PJI

In their search for new, better ways to diagnose periprosthetic joint infection, Rothman Institute at Jefferson researchers have discovered that measurement of C-reactive protein in the synovial fluid is extremely accurate, while measuring a patients- serum white blood cell count (WBC) and the percentage of neutrophils (PMN%), the conventional method for diagnosis, has a minimal role in the determination of PJI.

FDA accepts Genentech's pertuzumab BLA and grants Priority Review

Genentech, a member of the Roche Group, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company's Biologics License Application for pertuzumab and granted Priority Review.

LE strips can have a role in rapid diagnosis of periprosthetic joint infection

Rothman Institute at Jefferson joint researchers continue to seek better ways to diagnose and subsequently treat periprosthetic joint infection (PJI) in patients following total joint arthroplasty. Their latest research shows leukocyte esterase reagent (LE) strips, common in diagnosing urinary tract infections, can also have a role in rapid diagnosis of PJI.

Researchers discover how SHP-2 genetic defect may result in heart malformation

UNC researchers have discovered how the genetic defect underlying one of the most common congenital heart diseases keeps the critical organ from developing properly. According to the new research, mutations in a gene called SHP-2 distort the shape of cardiac muscle cells so they are unable to form a fully functioning heart.

Blood cell therapy works for nasopharyngeal cancer: Study

Scientists from the Queensland Institute of Medical Research have made a breakthrough in the treatment of throat cancer. The researchers have developed a therapy that uses a patient's blood to grow special white blood cells that recognize and fight infected cancer cells. The results of this study have been published in the journal Cancer Research.

Natural resistance to flu could hold key to universal vaccine

Researchers have found that on infecting 41 healthy volunteers with different strains of flu virus, those with higher levels of a specific type of white blood cell were less likely to develop severe illness. Now the team of researchers hopes to mimic the natural resistance shown by some of the volunteers, by creating a vaccine that boosts levels of a particular subset of the 'T-cells'.

Certain strains of P. aeruginosa cause WBCs to produce high levels of histamine

Could some cases of asthma actually be caused by an allergic reaction to a common environmental bacteria? New research findings published in the Journal of Leukocyte Biology suggests that this idea may not be as far-fetched as it seems. In a research report appearing in the February 2012 print issue, researchers show a link between common environmental bacteria and airway inflammation.

Study pinpoints genetic factors behind increased ALL risk in Hispanic children

Hispanic children are more likely than those from other racial and ethnic backgrounds to be diagnosed with acute lymphoblastic leukemia (ALL) and are more likely to die of their disease. Work led by St. Jude Children's Research Hospital scientists has pinpointed genetic factors behind the grim statistics.

SENP1 prevents STAT5 from becoming trapped in nucleus

When SUMO grips STAT5, a protein that activates genes, it blocks the healthy embryonic development of immune B cells and T cells unless its nemesis breaks the hold, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell.

Scientists develop new vaccine to treat cancer at pre-clinical level

Scientists in Trinity College Dublin, Ireland, have developed a new vaccine to treat cancer at the pre-clinical level. The research team led by Professor Kingston Mills, Professor of Experimental Immunology at Trinity College Dublin discovered a new approach for treating the disease based on manipulating the immune response to malignant tumours.

Scientists discover unexpected way in which a neutrophil prepares for battle

UCSF scientists have discovered the unexpected way in which a key cell of the immune system prepares for battle. The finding, they said, offers insight into the processes that take place within these cells and could lead to strategies for treating conditions from spinal cord injury to cancer.

Patients with PsA may benefit from new medications and surgeries

Medications or biologic agents that target T-cells, white blood cells involved in the body's immune system, appear to offer significant benefit to patients suffering from psoriatic arthritis (PsA), a type of arthritis that affects up to 48 percent of patients with the skin disease psoriasis, according to a new review article in the Journal of the American Academy of Orthopaedic Surgeons.

Ethanol, nonalcoholic compounds in red wine may reduce risk of vascular disease

Observational epidemiologic studies relating wine and alcohol to health all suffer from the fact that they, of necessity, compare people who prefer certain beverages, but not the beverages themselves. While there have been many intervention trials in animals, randomized trials in humans are less common. Randomized crossover trials, in which each subject receives all interventions in sequence, can be especially important as they tend to avoid baseline differences among subjects and can detect effects of different interventions with smaller numbers of subjects.

Non-toxin vaccine shows promise against lethal anthrax infection

Vaccination with the anthrax capsule-a naturally occurring component of the bacterium that causes the disease-protected monkeys from lethal anthrax infection, according to U.S. Army scientists. The study, which appears in the Jan. 20th print edition of the journal VACCINE, represents the first successful use of a non-toxin vaccine to protect monkeys from the disease.
