Genocea announces new data that supports novel approach for development of HSV-2 vaccine

Genocea Biosciences announced today the presentation of new data supporting its novel approach to developing a first-in-class, protein subunit therapeutic vaccine for Herpes Simplex Virus type 2 (HSV-2).

Neutrophils play an unexpected role in mediating insulin resistance

Researchers at the University of California, San Diego School of Medicine say neutrophils, an abundant type of white blood cell typically tasked with attacking bacteria and other foreign invaders, also plays an unexpected role in mediating insulin resistance - the central characteristic of type 2 diabetes, which afflicts an estimated 26 million Americans.

Novartis, Penn partner to study and commercialize novel cellular immunotherapies for cancer

In an alliance aimed at bringing a new, personalized immunotherapy approach to patients with a wide variety of cancers, the University of Pennsylvania and Novartis announced today an exclusive global research and licensing agreement to further study and commercialize novel cellular immunotherapies using chimeric antigen receptor (CAR) technologies.

TAU research identifies protein group that may kick-start allergic reactions

Allergies, or hypersensitivities of the immune system, are more common than ever before. According to the Asthma and Allergies Foundation of America, one in five Americans suffers from an allergy - from milder forms like hay fever to more severe instances, like peanut allergies which can lead to anaphylactic shock.

Human HLA genes are evolving much more rapidly than previously thought

Human HLA genes - the genes that allow our immune system to tell the difference between our own cells and foreign invaders - are evolving much more rapidly than previously thought, according to an article online on August 3rd in Trends in Genetics. The resulting degree of variation improves our ability to fight off disease, but could also present challenges to current worldwide efforts aimed at identifying potential donors for patients undergoing stem cell transplantation.

'Fight' between bacteria in the intestines linked to chronic disease

Results from a study conducted at Georgia State University suggest that a "fight" between bacteria normally living in the intestines and the immune system, kicked off by another type of bacteria, may be linked to two types of chronic disease.

TAT-ARC fusion protein helps treat acute liver failure

Acute liver failure is a life-threatening disease, characterized by a sudden, massive death of liver cells. Unfortunately, few treatment options exist, especially for advanced-stage liver failure. As a last resort a liver transplant may be the only remaining option.

Allergies may reduce risk of brain cancer

New research adds to the growing body of evidence suggesting that there's a link between allergies and reduced risk of a serious type of cancer that starts in the brain. This study suggests the reduced risk is stronger among women than men, although men with certain allergy profiles also have a lower tumor risk.

Composition of microbes in the gut changes dramatically during pregnancy

The composition of microbes in the gut changes dramatically during pregnancy, according to a study published by Cell Press in the August 3rd issue of the journal Cell. Although these changes are associated with metabolic disease under most circumstances, they could be beneficial in pregnant women.

Researchers identify how telomerase is recruited to chromosome ends

Stem cells are special. Nestled in muscle and skin, organ and bone, they bide their time over years or decades until called to replace damaged or lost tissue. One secret to their longevity is an enzyme called telomerase, which stills the relentless ticking of the molecular clock that limits the life span of other cells.

Myc-directed repression of tristetraprolin important for development and maintenance of cancer

Scientists from the Florida campus of The Scripps Research Institute have identified a protein that impairs the development and maintenance of lymphoma (cancer of the lymph nodes), but is repressed during the initial stages of the disease, allowing for rapid tumor growth.

B-cell substances may play a role in MS progression

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment.

Possible molecular link between circadian rhythm disturbances and increased inflammatory response

Scientists have known for some time that throwing off the body's circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic inflammatory diseases such as diabetes, obesity and cancer.

SPECT/CT with 99mTc-HMPAO-WBC can improve diagnosis of infectious endocarditis

When combined with standard diagnostic tests, functional imaging procedures have been shown to reduce the rate of misdiagnosed cases of infectious endocarditis. According to new research published in the August issue of The Journal of Nuclear Medicine, single photon emission computed tomography (SPECT)/computed tomography (CT) with 99mTc-hexamethylpropleneamine oxime-labeled white blood cells (99mTc-HMPAO-WBC) can improve the diagnosis of infectious endocarditis in hard-to-diagnose cases.

Researchers unlock genetic secrets of peripheral T-cell lymphomas

Researchers at Mayo Clinic have completed the world's first genome-wide sequencing analysis of peripheral T-cell lymphomas, unlocking the genetic secrets of this poorly understood and highly aggressive cancer of the immune system.

HIV people with high CD4 counts could work more hours per week

In a first-of-its-kind health campaign in Uganda, researchers from the University of North Carolina at Chapel Hill show that adults with HIV who had less severe infections could work more hours per week, and their children were more likely to be enrolled in school.

Researchers develop bioactive coating that actively suppresses brain's immune response

Brain-computer interfaces are at the cutting edge for treatment of neurological and psychological disorder, including Parkinson's, epilepsy, and depression. Among the most promising advance is deep brain stimulation (DBS) - a method in which a silicon chip implanted under the skin ejects high frequency currents that are transferred to the brain through implanted electrodes that transmit and receive the signals.

Research supports ability of some herbal agents against sunburn

Recent research supports the ability of some herbal agents, taken orally or applied topically, to prevent sunburn and limit the damage caused by excessive exposure to ultraviolet (UV) light.

Poor sleep can reduce effectiveness of vaccines

As moms have always known, a good night's sleep is crucial to good health -- and now a new study led by a UCSF researcher shows that poor sleep can reduce the effectiveness of vaccines.
