Japanese research group led by Prof. Makoto Tominaga and Dr. Takaaki Sokabe (National Institute for Physiological Sciences: NIPS), and Prof. Masayuki Takeda, Dr. Isao Araki and Dr. Tsutomu Mochizuki (Yamanashi Univ.), found that bladder urothelial cells have a sensor for stretch stimulation. Their finding was reported in the Journal of Biological Chemistry published on Aug 7, 2009.

Human cells are able to secrete a cancer-killing protein, scientists at the University of Kentucky's Markey Cancer Center have found.

Applying biological molecules from cell membranes to the surfaces of artificial materials is opening peepholes on the very basics of cell-to-cell interaction.

A new study reveals the importance of adenylylation in the regulation of cell signaling from bacteria to higher organisms.

The detailed structure of a protective 'jacket' that surrounds cells of the Clostridium difficile superbug, and which helps the dangerous pathogen stick to human host cells and tissues, is revealed in part in the 1 March issue of Molecular Microbiology.

A layer of "dark cells" in the retina that is responsible for maintaining the health of the light-sensing cells in our eyes has been imaged in a living retina for the first time.

Melbourne, Australia —26 February 2009— According to a new study, the frequency of regulatory T-cells (Treg) correlates to the severity of inflammation in allergic asthma, suggesting that Treg may play an important role in asthma pathogenesis.

Cell lifespan is limited by telomeres, DNA sequences that cap chromosomes and control the number of times a cell may be copied.

A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine.

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices.

Experiments at Johns Hopkins have found that the gradual maturing of embryonic cells into cells as varied as brain, liver and immune system cells is apparently due to the shut off of several genes at once rather than in individual smatterings as previous studies have implied.

University of Michigan researchers have discovered that a key protein in cells plays a critical role in not one, but two processes affecting the development of cancer.
