Elusive HIV shape change revealed; Key clue to how virus infects cells

Structural biologists at Children's Hospital Boston and Harvard Medical School have shown how a key part of the human immunodeficiency virus (HIV) changes shape, triggering other changes that allow the AIDS virus to enter and infect cells. Their findings, published in the Feb. 24 issue of the journal Nature, offer clues that will help guide vaccine and treatment approaches. Researchers led...

Timing is everything: First step in protein building revealed

Timing is everything, it seems, even inscience. A team led by Johns Hopkins scientists has unraveled the firststep in translating genetic information in order to build a protein,only to find that it's not one step but two.In a series of experiments, the scientists found that when yeast'sprotein-building machinery recognizes the starting line for a gene'sinstructions, it first alters its str...

Transplantation Of Monkey Embryonic Stem Cells Reverses Parkinson Disease In Primates

The replenishment of missing neurons in thebrain as a treatment for Parkinson disease reached the stage of humantrials over 15 years ago, however the field is still in its infancy.Researchers from Kyoto University have now shown thatdopamine-producing neurons (DA neurons) generated from monkey embryonicstem cells and transplanted into areas of the brain where these neuronshave degenerated i...

A much-needed shot in the arm for HIV vaccine development

International efforts towards developing avaccine against HIV infection have been given a much-needed boost bythe publication today of the Global HIV/AIDS Vaccine Enterprise'sscientific strategic plan, published online in the freely available,open-access global health journal PLoS Medicine.The Global HIV/AIDS Vaccine Enterprise is an international alliance ofindependent agencies and organiz...

NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

New York University biologists have uncovered how the innate immune system in mice's brains fights viral infection of neurons. The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brai...

Asthma may actually be prevented by Dust and Dirt

National Jewish Medical and Research Center researchers in USA say that a little dust and dirt in the home may help prevent asthma later in life. Environmental endotoxin may have an allergy-protective effect in some infants whose homes have high levels of the bacteria by-product. "Endotoxin seems to drive the immune system to produce cytokines that inhibit certain processes in the body th...

Virus Level could Predict Cervical Cancer Risk

Cervical cancer is one of the most common cancers in women. If it is caught and treated early, it is curable in most cases.// The Pap smear is the standard screening method for the disease. It is used to detect unusual, precancerous changes in cervical cells. Two strains of the human papilloma virus (HPV) are associated with an increased chance of getting the cancer, but not all women who...

Human Genome Project Achieves Technological Triumph

The completion of rough draft sequence of the human genes is a major scientific milestone and was achieved on 26.06.2000. The project began more than 10 years ago to map out almost 35 billion chemical letters that make up the recipe of human life. This breakthrough is expected to revolutionize the practice of medicine by paving the way for new drugs and medical therapies.Specific sequ...

Low Cholesterol Linked to Severe Depression and Violent Behavior in Men

It is not high levels of cholesterol but low levels that are making news. Recent reports are indicating that Low levels of Cholesterol maybe linked to depression and violent behavior.
