Effective immunity requires the coordinated activation of innate and adaptive immune responses. Natural killer (NK) cells are central innate immune effectors, but can also affect the generation of acquired immune responses to viruses and malignancies. How NK cells influence the efficacy of adaptive immunity, however, is poorly understood. Here, we show that(More)
The evolutionary survival of viruses relies on their ability to disseminate infectious progeny to sites of transmission. The capacity to subvert apoptosis is thought to be crucial for ensuring efficient viral replication in permissive cells, but its role in viral dissemination in vivo has not been considered. We show here that the murine cytomegalovirus(More)
Pigs were introduced into Australia and New Zealand in the 18th and 19th centuries, with some establishing feral populations. With few records of pig introductions into these two countries, molecular phylogenetic analysis was used to assess their origins. Mitochondrial (mt) control region sequence and nuclear glucosephosphate isomerase pseudogene (GPIP)(More)
Embryonic levels of retinoic acid (RA) and the response of cells to RA are critical to the normal development of vertebrates. To understand the effects of RA signaling in Fundulus heteroclitus, we exposed embryos to a range of RA concentrations of 2 h during gastrulation. Embryos exposed to low concentrations of RA (10(-10)-10(-7) M) develop normally,(More)
Chemokines are important mediators of the early inflammatory response to infection and modify a wide range of host immune responses. Functional homologs of cellular chemokines have been identified in a number of herpesviruses, suggesting that the subversion of the host chemokine response contributes to the pathogenesis of these viruses. Transcriptional and(More)
OBJECTIVE To use high-density genotyping to investigate the genetic associations of acute anterior uveitis (AAU) in patients with and those without ankylosing spondylitis (AS). METHODS We genotyped samples from 1,711 patients with AAU (either primary or combined with AS), 2,339 AS patients without AAU, and 10,000 control subjects on an Illumina Immunochip(More)
We have identified a novel family of five 3' co-terminal transcripts in murine cytomegalovirus (MCMV) arranged in a tail-to-tail orientation with respect to the MCMV glycoprotein H (gH) gene M75. They share the same exon 2 sequence but possess different exon 1 sequences. Two of these spliced transcripts (M73) encode the MCMV homolog of glycoprotein N (gN)(More)
Herpesviruses, such as murine and human cytomegalovirus (MCMV and HCMV), can establish a persistent infection within the host and have diverse mechanisms as protection from host immune defences. Several herpesvirus genes that are homologous to host immune modulators have been identified, and are implicated in viral evasion of the host immune response. The(More)
(A) The concentration-dependent effects of compound 1 and bortezomib on the proliferation of MDA-MB-231-4xUb-Luc reporter cell line were determined by the ATPlite assay at 72 h. (B) Accumulation of the 4xUb-Luc reporter in the stable MDA-MB-231 cell line was determined by incubation with the indicated concentrations of compounds for 8 h followed by(More)
Natural killer (NK) cells are an innate lymphoid cell lineage characterized by their capacity to provide rapid effector functions, including cytokine production and cytotoxicity. Here, we identify the Ikaros family member, Aiolos, as a regulator of NK-cell maturation. Aiolos expression is initiated at the point of lineage commitment and maintained(More)
