Scientists have known for some time that these individuals carry a genetic mutation (known as CCR5-Ä32) that prevents the virus from entering the cells of the immune system but have been unable to account for the high levels of the gene in Scandinavia and relatively low levels in areas bordering the Mediterranean.

Cigarette smoke worsens respiratory infections in infants

Studying Respiratory Syncytial Virus (RSV) to learn what puts children at risk for the most severe infections, Washington University researchers at St. Louis Children's Hospital found that a child's age at the time of infection and whether that child lives with a smoker could mean the difference between the sniffles and the intensive care unit.

DNA ejection from single phage particles

Studying phage, a primitive class of virus that infects bacteria by injecting its genomic DNA into host cells, researchers have gained insight into the driving force behind this poorly understood injection process, which has been proposed in the past to occur through the release of pressure accumulated within the viral particle itself.

alpha-defensin-1, a protein found in immune cells, can control HIV infection

Theresa Chang and colleagues at Mount Sinai School of Medicine analyzed how alpha-defensin-1 inhibits HIV infection in white blood cells (CD4+ T cells). Defensins have been shown to have anti-HIV activity. The body attempts to protect itself from HIV infection via the innate immune system.
