Critical considerations for adenovirus-based HIV vaccine trials

A clinical trial testing a candidate HIV vaccine known as the STEP study was halted in September 2007 after interim analysis indicated that the vaccine did not work. Moreover, subsequent analyses indicated that the vaccine made some individuals more susceptible to HIV, in particular individuals who had pre-existing immune effectors (antibodies) that recognized a component of the vaccine (adenovirus serotype 5 [Ad5]).

Synthetic drugs treat Crohn's disease in mice

A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists managed to trick the immune systems of mice into targeting one of the body's players in autoimmune processes, an enzyme known as MMP9.

LRI praises U.S. Congress for legislation that addresses early lupus detection and treatment

A top legislative priority of the Lupus Research Institute (LRI) -- funding for a nationwide lupus education effort for healthcare providers -- is included in the Fiscal 2012 omnibus appropriations bill (H.R. 2055) signed into law today by President Obama after passing in the House of Representatives and the Senate.

Neuroscientists discover gene responsible for HDLS

A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids.

Potential new strategy against bacteria with multi-drug resistant organisms

Vaccines with broader reach might be made by stimulating specialized immune cells to recognize foreign cell membrane proteins that are shared across bacterial species, say researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine in a report published online today in Immunity.

Researchers present results from 31 major studies of blood-related cancers at ASH 2011 meeting

Researchers from the John Theurer Cancer Center at Hackensack University Medical Center, one of the nation's top 50 best hospitals for cancer, presented results from 31 major studies of blood-related cancers - leukemia, lymphoma and multiple myeloma -- during the American Society of Hematology (ASH) Annual Meeting, December 10-13, 2011 in San Diego.

Faulty lipid metabolism may cause MS, says forensic anthropologist

An article to be published in the December 2011 issue of The Quarterly Review of Biology argues that multiple sclerosis, long viewed as primarily an autoimmune disease, is not actually a disease of the immune system.

FLT-PET imaging can effectively detect mantle cell lymphoma

Positron emission tomography (PET) and a molecular imaging agent that captures the proliferation of cancer cells could prove to be a valuable method for imaging a form of Non-Hodgkin's disease called mantle cell lymphoma, a relatively rare and devastating blood cancer.

Researchers evaluate Clade C HIV envelope protein in Phase I trial

In the first clinical trial of an injectable vaccine containing trimeric HIV envelope protein (gp140) relevant to the predominant strain of HIV in Africa, researchers from four UK academic centers (St George's University London, Imperial College, Hull York Medical School (HYMS; University of York) and the Medical Research Council Clinical Trial Unit) and from the Infectious Disease Research Institute (IDRI) have come together to evaluate whether the vaccine is safe for use in human volunteers.

Leishmania parasite develops combined resistance against drug, human immune system

Scientists of the Institute of Tropical Medicine (ITG) discovered a parasite that not only had developed resistance against a common medicine, but at the same time had become better in withstanding the human immune system.

Research into how flying fox spreads infectious diseases

The flying fox is an adorable doe-eyed bat with a dark side - it is the perfect vector for emerging infectious diseases from Asia. Susan Tsang, a PhD student in ecology and evolutionary biology at The City College of New York and the CUNY Graduate Center, turned to a revolutionary way to help fund her research into how this species spreads disease.
