Early treatment is key to combating hepatitis C virus
August 11, 2008Canadian researchers have shown that patients who receive early treatment for Hepatitis C virus (HCV) within the first months following an infection, develop a rapid poly-functional immune response against HCV similar to when infection is erradicted spontaneously, according to a new study published in the Journal of Virology. Therefore, early treatment can restore immune response against HCV and help eliminate the virus rapidly. This new discovery of the mechanisms of viral eradication could contribute to the development of new treatments.
About a quarter of infected individuals eradicate the infection spontaneously, without treatment. Led by Dr. Naglaa Shoukry and Dr. Julie Bruneau, affiliated to both the Research Centre of the Université de Montréal Hospital Centre and the Université de Montréal, as well as with researchers from the Institut national de la santé et de la recherché scientifique (Montréal branch), the study found that early treatment restores a rapid poly-functional immune response, characterized by the simultaneous production of multiple antiviral mediators.
HCV is transmitted through infected blood. Although a quarter of infected patients can eradicate the infection spontaneously, the majority develop persistent infection, a major cause of cirrhosis and cancer of the liver. The only approved treatment for HCV is an anti-viral drug known as pegylated interferon alpha. This drug is successful in only half of cases when administered during chronic infection. Success rates among those treated early after infection are significantly higher or around 90%.
In North America alone, most new HCV infections occur among intravenous drug users (IDUs), a vulnerable population that is often undiagnosed and untreated. In the study, researchers followed a group of IDUs at high risk of HCV infection before and immediately after exposure to HCV. Their findings clearly show the importance of early diagnosis and treatment of HCV - particularly in marginalized populations such as IDUs and aboriginal populations.

New Notre Dame study provides insights into the molecular basis of tumor cell behavior
A new study by a team of researchers led by Crislyn D'Souza-Schorey, associate professor of biological sciences at the University of Notre Dame, sheds light on the molecular basis by which tumor cells modulate their surroundings to favor cancer progression.
New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer
Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.

Immune Response and the Eye (Chemical Immunology) by Jerry Y. Niederkorn (Editor), Henry J. Kaplan (Editor) In memory of J. Wayne Streilein, the pioneer in ocular immunology The second edition of Immune >Response and the Eye' highlights recent insights into the >dangerous compromise' between the immune system and the eye, which protects the eye against pathogens while limiting inflammation and immune-mediated injury to ocular tissues with little or no regenerative potential. It discusses the broad spectrum of physiological, immunological, anatomical, and biochemical adaptations that conspire to closely regulate the tone and tenor of immune responses in the eye. This volume further describes immune-mediated diseases that occur when the compromise between the immune system and the eye is breached. This breakdown in immune privilege threatens the vision of millions each year. Finally, recent... |

Understanding Hereditary Angioedema: A Mysterious Out-of-Control Immune Response Part of the award winning public television series Healthy Body/Healthy Mind. Its called Hereditary Angioedema and its so rare popular television shows have used it as one of their mystery diagnoses. But for the people who suffer with this condition the drama associated with an episode of hereditary angioedema is anything but entertaining. It can be harrowing and horrifying because a person's face or knees or other parts of the body that once looked normal suddenly takes on grotesque proportions due to an unusual amount of swelling. This condition baffled scientists and researchers for many years but today there are new treatments for hereditary angioedema that are helping people with this condition live healthy normal lives. In this program we'll hear what the experts have discovered... |

Chlamydia pneumoniae immunology: Innate Immune Responses induced by Chlamydia pneumoniae infection by Vjera Magdalenic (Author) Chlamydiae are common pathogens that cause a number of serious but preventable diseases in both humans and animals. In the recent years, Chlamydia pneumoniae has emerged as a major cause of human respiratory disease and more importantly, it has been linked to the establishment and exacerbation of serious chronic diseases including atherosclerosis and ischaemic heart disease, multiple sclerosis and reactive arthritis. There has been a lot of research into host responses to chlamydial infections and the development of immunopathology; but considerable gaps in our knowledge remain. The work described here aimed to analyse the early innate immune responses in the lung following C. pneumoniae infections with a view to better understanding host-pathogen interactions and the... |
