A new study to be published in the Journal of Clinical Investigation shows that wounding of the skin of humans triggers the production (by skin cells known as keratinocytes) of the active form of vitamin D3, which, in turn, induces an immune response that includes the production of antimicrobial peptides, such as cathelicidin, and the upregulation of receptors that recognize microbial components, such as TR2 and CD14.
Researchers at the National Institutes of Health and other institutions have found a second genetic defect that accounts for previously unexplained forms of osteogenesis imperfecta (OI), a disorder that weakens bones, sometimes results in frequent fractures and is sometimes fatal.
