Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses
Researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have made the surprising discovery that flaviviruses, which cause such serious diseases as West Nile fever, yellow fever and forms of encephalitis, evade immune system defenses in different ways depending on whether they are transmitted by mosquitoes or ticks. This findin...Virus uses tiny RNA to evade the immune system
In the latest version of the hide-and-seek game between pathogens and the hosts they infect, researchers have found that a virus appears to cloak itself with a recently discovered gene silencing device to evade detection and destruction by immune cells. The report by Howard Hughes Medical Institute (HHMI) researchers in an article published in the June 2, 2005, issue of Nature may be the...Study shows how herpes infects cornea, evades immune cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine. Both strains of the herpes virus -- HSV-1, the strain that causes cold sores on the mouth, an...Tumor cells evade death through autophagy
Autophagy is a cellular process that enables cells to turnover their contents, something that they do frequently. Autophagy is initiated in tumor cells by chemotherapy and radiation, but it is not known if this contributes to tumor cell death or helps tumor cells survive the anti-cancer therapy. However, in a study using a mouse model of B cell lymphomas, researchers from the University of Pennsy...Herpes Infects Cornea, Evades Immune Cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers// at the University of Illinois at Chicago College of Medicine. The study appears in the Sept. 25 issue of the Journal of Cell Biology. Both strains of the herpes virus -- HSV-1, the strain that causes cold sores on the...Researchers Discover How Cancer Evades the Immune System
A study on various kinds of cancer, conducted by researchers at the University of Southern California, has brought about the discovery of a new method to identify the genetic changes that enable tumours to evade the body's immune system. The findings, demonstrated in human breast and colorectal cancers, are significant to the field of medicine because they may lead to the advancem...Researchers Discover Method for Identifying How Cancer Evades the Immune System
PHILADELPHIA, July 3, 2007-- One of the fundamental traits of atumor – how it avoids the immune system – might becomeits greatest vulnerability, according to researchers from theUniversity of Southern California. Their findings,demonstrated in human breast and colorectal cancers, indicate thata technique for determining a tumor’s “immunesignature,” could be...
