Toll-free autoimmunity
Proteins secreted by parasite eggs might hold the key to the next antiinflammatory therapy. On page 1319, Smith and colleagues describe the first chemokine binding protein (CKBP) produced by a human pathogen and show that it can suppress acute inflammation in disease models. The blood-dwelling worm Schistosoma mansoni takes advantage of the host’s immune system in two ways. It subverts specific...

Studies were conducted to evaluate the impact of time and cryopreservation on aldehyde oxidase (AO) activity in human hepatocytes isolated from 10 donor livers, using O-benzylguanine as a probe substrate. In addition, variability in activity was assessed using cryopreserved hepatocytes from 75 donors. Substantial donor-dependent loss in AO activity within 24 hours after isolation of hepatocytes...

Prior work demonstrates that mammalian microRNA (miRNA or miR) expression requires RNA polymerase II (Pol II). However, the transcriptional requirements of many miRNAs remain untested. Our genomic analysis of miRNAs in the human chromosome 19 miRNA cluster (C19MC) revealed that they are interspersed among Alu repeats. Because Alu transcription occurs through RNA Pol III recruitment, and we foun...

1106 Once upon a time, the world seemed simple when viewed through the eyes of evolutionary biologists. All genomes were tightly controlled by various forms of natural selection. DNA encoded functional genes, and most mutations that occurred were rejected through negative selection. Those exceptional mutations that were beneficial substituted for the original gene variant (allele) and spread th...
