In DNA, abasic sites (apurinic/apyrimidinic or AP sites) occur through spontaneous hydrolysis of the glycosidic bond that joins the base to the deoxyribose ring (a common reaction following formation of some kinds of DNA adducts) or through the action of DNA glycosylases during repair of damaged bases. In double-stranded DNA,… Read More

Dec. 13, 2018, 10:15 AM by Bill Snyder Eosinophils are a type of white blood cell that plays many roles in the body, including helping to maintain metabolic homeostasis, the steady state that ensures the body is adequately fueled and waste is eliminated. Previous studies have found the adipose (fatty)… Read More

Dec. 13, 2018, 10:00 AM by Leigh MacMillan Immune checkpoint inhibitors — cancer therapies that remove the “brakes” on the adaptive anti-tumor immune response — have had remarkable success in melanoma and lung cancer. Response rates to these immunotherapies in breast cancer have been disappointing, perhaps because breast cancers are… Read More

Dec. 13, 2018, 9:45 AM by Bill Snyder (iStock) The exocyst is a protein complex essential for life, that is comprised of eight subunits and is a crucial component in vesicle trafficking. The mechanisms by which exocysts assemble and deliver vesicles containing important biological materials to the cell surface has… Read More

Figure courtesy of A.R. Greenplate. Copyright 2018. Cytomics, the “omics” of cell identity, offers the opportunity to systematically identify all cells in a tissue or patient sample, and the recent advent of high-dimensional flow and mass cytometry to the cytomics arsenal has markedly increased its power. Cytomics is particularly valuable… Read More

Dec. 6, 2018, 10:49 AM by Bill Snyder Pulmonary-renal syndrome (PRS) refers to a group of rare but potentially fatal conditions that nearly always are caused by a misguided attack by the body’s immune system on the lungs and kidneys. Coughing up blood and blood in the urine are telltale… Read More

Dec. 6, 2018, 10:24 AM by Bill Snyder Researchers at Vanderbilt University Medical Center and colleagues have isolated a human monoclonal antibody that can “neutralize” the West Nile virus and potentially prevent a leading cause of viral encephalitis (brain inflammation) in the United States. Their findings, reported last week… Read More
