First glimpse of how HIV swamps the gut's immune cells

We've been given the first glimpse of HIV in attack mode in the gut, shedding light on how the virus hijacks immune cells, multiplies and spreads throughout the body. A team of biochemists have used electron tomography microscopes to capture the high-resolution, 3D images.

How a House Finch Disease Reshaped What We Know About Epidemics

One team of researchers was able to study a highly virulent disease in House Finches. Their recent paper in PLOS Biology sheds light on what makes some disease-causing microbes, or pathogens, more harmful than others.

Discovering where HIV persists in spite of treatment

Recently discovered T memory stem cells may be long-term viral reservoir, potential targets for future treatment.

How HIV Destroys Immune Cells

HIV leads to AIDS primarily because the virus destroys essential immune cells called CD4 T cells, but precisely how these cells are killed has not been clear. Two papers published simultaneously today (19 December) in Nature and Science reveal the molecular mechanisms that cause the death of most CD4 T cells in lymphoid tissues, the main reservoir for such cells, during infection.

Aggressive HIV strain leads to faster AIDS development

The new recombinant strain from West Africa speeds up the time taken from the infection stage to the development of AIDS, to around five years.

HIV may be becoming less fit as it adapts to the immune system

HIV, at least in some parts of the world, may be developing a lower replicative capacity as it adapts to variations in the human immune system, studies

Rift widens over structure of HIV’s molecular anchor

Studies of a potential vaccine target bolster claims that an earlier paper was flawed.

Bursting HIV’s bubble

HIV has a fatty outer membrane similar to that surrounding a living cell. This membrane probably acts like a balloon—in other words the pressure inside it is greater than the pressure outside it. That means it can be burst, which is what some scientists believe provides the driving force by which a virus injects its genetic material into a cell in order to infect it.

Gene discovery could lead to new types of HIV treatments

Scientists have identified a gene which they say may have the ability to prevent HIV, the virus that causes AIDS, from spreading after it enters the body. In an early-stage study in the journal Nature, researchers said the gene, called MX2, appears to play a key role in how HIV is controlled in human cells.

These Renderings of HIV Show That a Deadly Virus Can Be Beautiful

For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Artists were invited to create renderings of HIV – and the winning images are as educational as they are beautiful.
