Low cholesterol in immune cells tied to slow progression of HIV

People infected with HIV whose immune cells have low cholesterol levels experience much slower disease progression, even without medication, according to University of Pittsburgh Graduate School of Public Health research that could lead to new strategies to control infection.The Pitt Public Health researchers found that low cholesterol in certain cells, which is likely an inherited trait, affects the ability of the body to transmit the virus to other cells.

Early treatment reduces viral reservoirs but does not prevent rebound

Antiretroviral therapy started during the first several days after infection limited dissemination of an HIV-like virus throughout the body and establishment of cellular and tissue reservoirs in monkeys,

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.

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.
