Intracellular bacterial communities in cystitis; rifapentine cures TB in mouse model; and more

A study published this week in the open access journal PLoS Medicine presents convincing evidence that intracellular bacterial communities (IBCs) commonly exist in women with bladder infections and may contribute to the recurrence of these infections.

Bacteria that cause urinary tract infections invade bladder cells

Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells.

Researchers report protein interactions of MAP kinase signaling pathway

The Stowers Institute's Rong Li Lab, in collaboration with the Institute's Imaging Center, has achieved a quantitative in vivo measurement of the dynamic protein-protein interactions in the mitogen-activated protein (MAP) kinase cascade signaling pathway, which is critical to growth and differentiation decisions in all eukaryotic cells.

Intestinal parasite Giardia uses an osmotic 'suction cup' to hang on

Known in America chiefly as the bane of hikers, the single-celled intestinal parasite Giardia lamblia is a major cause of diarrheal illness worldwide with estimates of 100 million infections a year.

Cell shape - scientists gain better understanding with new assay

Cells in our body come in various shapes and sizes. Each cell is shaped in such a way as to optimise it for a specific function. When things go wrong and a cell does not adopt its dedicated shape, its function can be impaired and the cell can cause problems in the body.

Alcohol and tobacco use doesn't boost HPV-related cancer risk

Heavy smoking and drinking are known to cause head and neck cancer. Infection with human papillomavirus type 16 (HPV16), a common strain of the sexually-transmitted HPV virus, is another known risk factor for head and neck cancer, which affects about 500,000 people each year worldwide.
