Better understanding of immune response to HIV infection

The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells.

New saliva-based HIV test gives results in 20 minutes!

The usual waiting period for the results of a HIV test can seem like an eternity, especially in emergency situations where results are needed immediately. Also it requires a blood sample, which is invasive and often painful. Recognizing the urgent need for a faster and less invasive diagnostic method, Dr. Nitika Pant Pai, from Marina Klein's research team at the MUHC has just finished testing a new saliva-based test that gives results in approximately 20 minutes! She describes her findings in an article that will appear in the May 6th, 2008 issue of PLoS Medicine.

Cancer immunotherapy shows long-term promise in lung cancer

New, long-term results from a clinical trial presented at the 1st European Lung Cancer Conference jointly organized by the European Society for Medical Oncology (ESMO) and the International Association of the Study of Lung Cancer (IASLC) show that MAGE-A3 ASCI (Antigen-Specific Cancer Immunotherapeutic), an immune-boosting treatment for lung cancer patients, reduces the risk of relapse after surgery -- to the same extent as chemotherapy but without the side-effects of chemotherapy.

Prostate cancer screening programme leads to bigger fall in death rates than surrounding areas

The expected number of deaths from prostate cancer more than halved in the Tyrol after a programme was introduced to improve early detection and treatment of the disease, according to research published in April issue of the urology journal BJU International.

Scientists cast doubt on value of screening for prostate cancer

Even though deaths from prostate cancer death have fallen in the U.S. since screening became more common, new research is suggesting that this does not justify the need for such tests.

Drugs in the pipeline: new therapies that could change treatment strategies

The investigational drug AZD2171 (cediranib) may help shrink tumors and prolong survival of patients with a relatively common, aggressive type of brain cancer, according to results from a clinical trial conducted by Boston researchers.

Scientists create monoclonal antibody libraries against avian influenza

An international group of American and Turkish research scientists, led by Sea Lane Biotechnologies, has created the first comprehensive monoclonal antibody libraries against avian influenza (H5N1) using samples from survivors of the 2005/2006 "bird flu" outbreak in Turkey.

New mucosal vaccine against anthrax effective in early tests

Early studies show that a new mucosal vaccine against anthrax has the potential to provide military personnel with more effective and efficient protection against a "popular" bioweapon, according to a study published in the journal Clinical and Vaccine Immunology (CVI).

T-cell multiplication unexpectedly delayed after infection

In a surprising outcome that overturns the conventional wisdom on the body's immune response to infection, scientists at The Scripps Research Institute have shown that T cells do not begin proliferation until up to three days after infection.

Better understanding of how T-cell leukemias and other disorders arise

Contrary to the currently accepted model of T-cell development, researchers at the University of Pennsylvania School of Medicine have found that juvenile cells on their way to becoming mature immune cells can develop into either T cells or other blood-cell types versus only being committed to the T-cell path.

Distinguishing non-TB pulmonary disease from TB

A diagnostic kit shows new promise for distinguishing between tuberculosis (TB) and its infections from disease caused by related mycobacteria family, which mimic TB and other lung disease in symptoms but require distinctly different clinical treatments.
