U of S Vaccine and Infectious Disease Organization team discovers key step in flu virus replication

...ness research." To survive, the influenza virus hijacks the host animal or human's cellular machinery and forces it to make more copies of the virus. The researchers believe that the cellular events involved in this process are an excellent target for interventions against influenza. The study reveale...

HIV infection requires an accomplice: B cells with special protein direct HIV to T cells

...mune system, where HIV replicates and thrives. HIV hijacks T cells by binding to a cell membrane molecule called CD4 and to either or both of two other receptors, from which the two strains of HIV, X4 and C5, take their names. Once anchored on the membrane, it's able to slither inside and take command of the...

Scientists a step closer to protecting world's most important crop

...ture, how the world's most destructive rice-killer hijacks its plant prey. In order to infect plants the fungus has to inject its proteins into the plant's own cells where they overcome the plant's defences allowing a full scale invasion by the fungus. Until now it's not been known how the fungus delivers ...

Shutting down the HIV assembly line

...susceptible cell, the human immunodeficiency virus hijacks that cell's normal machinery to produce carbon copies of itself. New HIV particles roll off the cellular assembly lines, burst like bubbles out of the cell, and float off to invade other cellular factories. Vanderbilt University Medical Center invest...

Scientists discover that host cell lipids facilitate bacterial movement

...the cycle anew. Essentially Listeria takes over or hijacks the host cell's actin cytoskeleton to move within cells, and to spread from cell to cell." In most cells, two membrane lipids, PIP2 and PIP3, are associated with the formation of new actin filaments. PIP3 is synthesized from PIP2 by an enzyme called...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

...omes malicious, tries to get outside the area, and hijacks the respiratory machinery of a cell." The biocavity laser It is these changes - a kind of beefing-up of the criminal forces - that Gourley's device, called a biocavity laser, detects. A nano-thin layering of gallium aluminum arsenide combinations ...
