Could gold be the key to making gene therapy for HIV?
A proof-of-principle study shows that gold nanoparticles loaded with CRISPR and other gene-editing tools safely and effectively edited blood stem cells.
Infections with human immunodeficiency viruses (HIV) and the often resulting acquired immunodeficiency syndrome (AIDS) are still among the most life-threatening challenges for modern healthcare. Keep reading to find out about more about this sexually transmitted infection and latest research on treatments.

Until now, researchers haven’t been able to accurately quantify a latent form of HIV that persists in patients’ immune cells. A new genetic technique is fast and 10 to 100 times more accurate than previous diagnostics. This hidden, inactive version of HIV embeds into cells’ genomes and can persist despite otherwise successful therapies – thwarting attempts to cure the infection. Using a…
The claim of a chinese professor has caused quite a controversy: He Jiankui announced that he successfully modified human DNA to prevent two girls from contracting HIV. Upon the leak of this research, ethicists and scientists alike condemned Jiankui's gene editing in humans. West Virginia University Vice President and Executive Dean for Health Sciences Dr. Clay Marsh says that although “a lot…
Around one percent of people infected with HIV produce antibodies that block most strains of the virus. These broadly acting antibodies provide the key to developing an effective vaccine against HIV. Researchers from the University of Zurich and the University Hospital Zurich have now shown that the genome of the HI virus is a decisive factor in determining which antibodies are formed.
Researchers have developed a novel way for dating "hibernating" HIV strains, in an advancement for HIV cure research in the province. The HIV cure research confirms that dormant HIV strains can persist in the body for decades.
While treatments for HIV mean that the disease is no longer largely fatal, the world still lacks a true therapy that can eradicate the virus across a globally—and genetically different—population.
While specific data remains limited on a possible connection between online forums and sexually-transmitted infections (STIs), this has become an area of increased focus. The subject was, for example, aired in April by one of the UK’s leading experts in the field, during the 28th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), in Madrid. At the four-day event, Dr…
Feline AIDS is caused by the Feline Immunodeficiency Virus (FIV), which is very similar to the HIV-1 virus that affects millions of humans. While FIV does not infect humans, many groups research the virus to benefit cats, and perhaps more importantly, because of its many parallels with the AIDS virus. Despite the use of dedicated drugs, HIV-1 manages to thrive and multiply within the cell and…
Drugs, alcohol and suicides are contributing to an alarming drop in US life expectancy, particularly among middle-aged white Americans and those living in rural communities, warn experts in The BMJ. They argue that the ideal of the “American Dream” is increasingly out of reach as social mobility declines, and fewer children face a better future than their parents.
Through gene therapy, researchers engineered blood-forming stem cells (hematopoietic stem/progenitor cells, or HSPCs) to carry chimeric antigen receptor (CAR) genes to make cells that can detect and destroy HIV-infected cells. These engineered cells not only destroyed the infected cells, they persisted for more than two years, suggesting the potential to create long-term immunity from the virus…
Researchers at the Duke Human Vaccine Institute have led an effort to develop a more accurate way to gauge the incidence of HIV infections in large populations, which will improve research and prevention strategies worldwide. The new method more correctly identifies new vs. long-standing infections – an important distinction for determining where to target public health measures and research,…
The WHO European Region is the only region worldwide where the number of new HIV infections is rising. With more than 160 000 people newly diagnosed with HIV across the Region, including more than 29 000 new cases from the European Union and European Economic Area (EU/EEA), this trend continued in 2016. One reason for this worrying trend: over half (51%) of the reported HIV diagnoses happen in a…
Beckman Coulter Life Sciences is launching an international HIV/AIDS award at the 2016 conference for the African Society for Laboratory Medicine (ASLM) being held in Cape Town, South Africa (December 3 to 8).
The HIV: The Long View initiative launches today with the release of an evidence-based report that examines the potential implications of future healthcare trends on HIV care and management in Western Europe.
Scientists at the Institute of Molecular Biotechnology (IMBA) and the Max F. Perutz Laboratories (MFPL) in Vienna have discovered a new way to turn the immune system’s weapons against fungal invaders. This knowledge could lead to the development of new and improved anti-fungal treatments.
Georgetown University researchers are reporting the first case of Alzheimer’s disease diagnosed in an HIV-positive individual. The finding in a 71-year-old man triggers a realization about HIV survivors now reaching the age when Alzheimer’s risk begins to escalate.
An international research group with essential participation of the Paul-Ehrlich-Institut, has identified NLRX1, a cellular factor of the human cell that is indispensable to the replication of Human Immunodeficiency Virus (HIV-1). This factor plays a key role in attenuating the innate immune system towards HIV-1. Until now, the significance of NLRX1 for the replication of HIV-1 and the…
Many viral diseases tend to become chronic – including infections with the HI virus. In persons affected, the immune response is not sufficient to eliminate the virus permanently. Scientists at the University of Bonn have now identified an immune factor which is partially responsible for this. Their results give rise to hopes for new therapeutic approaches. The work, which included researchers…
Nothing could be simpler: a drop of blood is placed on a special carrier substance; after a wait of a few minutes, the slide is placed on a device that emits polarised light thanks to an inexpensive polarisation filter. It is covered with a lid containing a second polarisation filter, which blocks the light from all materials except crystalline or materials with directional properties.
