The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters. A key player on this stage is an enzyme called a helicase.
Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease. The researchers found that after HIV docks onto a host cell, it dramatically lowers the energy required for a cell membrane to bend, making it easier for the virus to infect immune cells.
Two new studies emphasize the importance of delivering measles and influenza vaccines to HIV-infected individuals. Both studies are published in the August 1 issue of The Journal of Infectious Diseases, now available online.
An international collaboration between European, Australian and American researchers has unveiled some of the genetic mysteries explaining why some people naturally keep HIV levels almost undetectable, whereas others quickly lose control of the infection.
An international team of researchers has identified three gene variants in the DNA of 486 people infected with HIV that appear to have helped some of the patients fight off the virus and delay the onset of full-blown AIDS.
The first genome-wide association study of an infectious disease, conducted by an international group of researchers through the Center for HIV/AIDS Vaccine Immunology (CHAVI), has yielded a new understanding of why some people can suppress virus levels following HIV infection.
Scientists at the University of California, Santa Barbara have made a significant discovery relating to viral infections in humans.
Leukaemia rates in children and young people are elevated near nuclear facilities, but no clear explanation exists to explain the rise, according to a research review published in the July issue of European Journal of Cancer Care.
Many parts of Kerala are reeling under the impact of viral fever, including chikungunya, with the problem spreading to new areas where patients are pouring into hospitals to seek treatment.
A genetically engineered herpes simplex virus, primarily known for causing cold sores, may help keep arteries ?free-flowing? in the weeks following angioplasty or stent placement for patients, according to research published early in the online edition of PNAS (Proceedings of the National Academy of Sciences of the United States of America).
