Researchers discover ‘brake’ that interferes with HIV's development into infectious agent

Viewed with a microscope, the virus faintly resembles a pineapple--the universal symbol of welcome. But HIV, the virus that causes AIDS, is anything but that. It has claimed the lives of more than 35 million people so far.

Researchers explore new method of destroying tumor cells

Researchers from Lomonosov MSU Faculty of Biology have studied the stages of entosis, a process of cell death when one cell invades the other and gets digested inside of it. Entosis could become a new method of destroying cancer cells.

Biologists reveal how bacterial cells thrive in oxygen-poor environments

Columbia University biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell. The finding could explain how some bacteria, such as Pseudomonas aeruginosa (P. aeruginosa), are able to thrive in oxygen-poor environments like biofilms and resist antibiotics.

Research reveals fundamental process used by immune system to recognize invading pathogens

The body's homeland security unit is more thorough than any airport checkpoint. For the first time, scientists have witnessed a mouse immune system protein frisking a snippet of an invading bacterium. The inspection is far more extensive than researchers imagined: the immune system protein, similar to those in humans, scans the bacterial protein in six different ways, ensuring correct identification.

Early intervention may be crucial to successful treatment of Friedreich's ataxia

New research published today in Disease Models & Mechanisms indicates that early intervention should be a key target in the development of new therapeutics for Friedreich's ataxia, as current treatments may be administered too late to target the disease effectively.

Research reveals presence of potential autoantigen in patients with aggressive kidney disease

New research reveals the presence of abundant levels of a certain protein in the kidneys of patients with fibrillary glomerulonephritis (FGN). In FGN, large amounts of protein become trapped in the millions of filtering units-;or glomeruli-;that make up the kidney.
