Some viral-vector vaccines may cause more harm than good

Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development.

Suppressing herpes virus may reduce infectiousness of HIV

A recent study of men co-infected with herpes simplex virus type 2 (HSV-2) and HIV revealed that drugs used to suppress HSV decrease the levels of HIV in the blood and rectal secretions, which may make patients less likely to transmit the virus.

Viral infection affects important cells' stress response

Viral infection disrupts the normal response of mammalian cells to outside deleterious forces, cleaving and inactivating a protein called G3BP that helps drive the formation of stress granules, which shelter the messenger RNAs that carry the code for protein formation, said researchers from Baylor College of Medicine in Houston.
