Cancer-Killing Viruses Employ Multiple Mechanisms

...es which include the naturally occurring reovirus, infect cancer cells while sparing healthy tissues. Once inside the tumor cell, the viruses produce thousands of copies of themselves, causing tumor cells to burst. After tumor cells die, viruses clear rapidly from the body without harming the patient. Mor...

Virus Can Mutate lethally With Help Of Carbohydrates

...nging the carbohydrates they attach to are able to infect cells more efficiently. This finding the researchers hope would prove to be valuable to scientists for finding ways to fight cancer or brain diseases. The discovery they hope would also explain how flu and other viruses are always to stay a step ahea...

They slip unnoticed into and multiply inside macrophages, the very immune system// cells the body relies on to seek and destroy invading microbes. Just how Salmonella escapes detection by macrophages, turning predator cells to prey comp...

Hotel Guests Often Leave Their Cold Behind

...e present for their germs to linger. In order to infect an individual, germs must reach the eyes or the nose, usually by way of a person’s own fingers. So researchers then set out to learn if germs lingering in the environment can make the leap from surfaces to fingers. In order to test this leap, resea...

Gene therapy Beneficial in Parkinson's Disease

... adeno-associated virus, which is known to readily infect humans. This virus has never been shown to cause disease. The genes used by both teams were quite different. The team, led by Dr. Matthew J During from the Weill Cornell Medical Center in New York, used a gene responsible for the synthesis of enzym...

HIV Takes Advantage of Rivalry among T cells

..., occurs when several viral strains simultaneously infect one person. In this case, T cells compete to recognize the different strains. The winners – the T cells that the body produces in mass quantities to fight the disease – are the ones with the best overall record against the most recogniztable strains....

Scinetists Alert to Onset of Pandemic through Bird flu Mutations to Humans

...an flu viruses have an ability to evolve to easily infect humans by exchange of genes with human viruses which permits them to recognize human receptor molecules and gain easy access to cells, typically in the human respiratory system. This occurs when human patients are exposed at the same time to a huma...

Britain Faces Aids Epidemic
