Skin cells use new molecule to send touch information to the brain In a study published in the April 6 online edition of the journal Nature, a team of Columbia University Medical Center researchers led by Ellen Lumpkin, PhD, associate professor of somatosensory biology, solve an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures. Touch is the last frontier of sensory neuroscience. The cells and molecules that initiate...

A study led by scientists at The Scripps Research Institute (TSRI) has helped solve a long-standing mystery about the sense of touch. The "gentle touch" sensations that convey the stroke of a finger, the fine texture of something grasped and the light pressure of a breeze on the skin are brought to us by nerves that often terminate against special skin cells called Merkel cells. These skin cells' role in touch sensation has long been debated in the scientific community. The new study,...

New study shows women tend to have better sense of touch due to smaller finger size People who have smaller fingers have a finer sense of touch, according to new research in the Dec. 16 issue of The Journal of Neuroscience. This finding explains why women tend to have better tactile acuity than men, because women on average have smaller fingers. "Neuroscientists have long known that some people have a better sense of touch than others, but the reasons for this difference have been...

Cells required for sensory coding of light touch needed to distinguish shapes and textures Scientists have proved experimentally what has been suspected since the discovery of Merkel cells in the skin over a century ago: the sense of light touch that is critical for hand dexterity would not be possible without these cells. In a presentation at the American Society for Cell Biology (ASCB) 49th Annual Meeting, Dec. 5-9, 2009 in San Diego, Ellen Lumpkin, Ph.D., of Baylor College of Medicine in...

Case Western Reserve University School of Medicine assistant professor of pediatrics, neurosciences and otolaryngology, Stephen M. Maricich, M.D., Ph.D., and his team found that Merkel cells originate in the skin, not the neural crest lineage, as previously speculated. The study, "Mammalian Merkel Cells are Descended from the Epidermal Lineage", was recently published in the online version of Developmental Biology and is slated its future print edition. "Merkel cells," discovered by Friedrich...

A new study resolves a 130-year-old mystery over the developmental origin of specialized skin cells involved in touch sensation. The findings will appear in the October 5, 2009 issue of the Journal of Cell Biology (online September 28). First described in 1875, Merkel cells are neuroendocrine cells that reside in the vertebrate epidermis, passing mechanical stimuli on to sensory neurons. In mice, they are mainly found in the paws and around the whiskers but, because they express proteins...

The Merkel cell polyomavirus (MCPyV) is the only human polyomavirus known to be associated with a rare skin cancer, known as Merkel cell carcinoma, according to a new study published online September 23 in the Journal of the National Cancer Institute. The majority of patients with Merkel cell carcinoma carry MCPyV, but little is known about the polyomavirus' prevalence in the general population and the association between circulating antibodies against MCPyV and the rare skin cancer. Denise...
