The layers of skin that form the first line of defense in the body’s fight against infection have revealed a unanticipated secret. The single cell type that was thought to be behind the skin’s immune defense has been found to have a doppelganger, with researchers from the Walter and Eliza Hall Institute showing the cells, despite appearing identical, are actually two different types. Institute scientists Dr Michael Chopin, Dr Stephen Nutt and colleagues from the institute's...

Study examines changes in the penis microbiome Male circumcision reduces the abundance of bacteria living on the penis and might help explain why circumcision offers men some protection against HIV, according to a study led by the Translational Genomics Research Institute (TGen). Removing the foreskin caused a significant shift in the bacterial community or microbiome of the penis, according to a study published today by the online journal mBio. This international collaboration...

A study by a Baylor College of Medicine physician-researcher has shed light on the most effective treatment for adults with Langerhans cell histiocytosis (LCH) in bones. LCH is a disease that can affect the skin, mouth, ears, bones, brain, gastrointestinal system, liver, spleen, or bone marrow. In the study, appearing in the current issue of PLOS ONE, researchers reviewed health records for 58 adults with the disease and compared the effectiveness of three chemotherapy treatments —...

How our skin says, 'Don't worry, these are good guys,' revealed today in PNAS There are more bacteria living on our skin and in our gut than cells in our body. We need them. But until now no-one knew how the immune system could tell that these bacteria are harmless. Centenary Institute researchers in Sydney have discovered a set of peacekeepers–immune cells in the outer layers of our skin that stop us from attacking friendly bacteria. The work will open the way to new...

Histiocytosis is considered a rare disease but doctors at Baylor College of Medicine and Texas Children's Cancer Center and Hematology Service would argue the accuracy of that label. They are seeing more and more patients with the disease and that has led to important research advances. "Our knowledge of this disease has skyrocketed over the last three years," said Dr. Kenneth McClain, professor of pediatrics "“ hematology/oncology at BCM and director of the Histiocytosis Program at...

LINTHICUM, Md., April 27 /PRNewswire-USNewswire/ -- Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury -- without reducing pleasure or causing sexual dysfunction. The first study, by researchers in Australia, shows that the inner foreskin has the largest concentration of Langerhans' cells, which are the...

Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury - without reducing pleasure or causing sexual dysfunction. The first study, by researchers in Australia, shows that the inner foreskin has the largest concentration of Langerhans' cells, which are the initial cellular targets in the sexual transmission of HIV....

People with genital herpes, gonorrhea, syphilis and chlamydia have an increased risk of being infected if exposed to HIV, Dutch researchers warn. Teunis B.H. Geijtenbeek and colleagues at VU University Medical Center in Amsterdam said a way in which STDs can increase acquisition of HIV-1 infection in an ex vivo human skin explant -- isolation of cells from a piece of tissue. In the ex vivo human skin explant model, although immature immune cells known as Langerhans cells captured HIV,...
