The efficacy of praziquantel for the treatment of Schistosoma japonicum in humans is reported from a cross-sectional survey conducted in 33 villages in Sichuan Province. Infection prevalence was found to be 5.7% (185 infected of 3,269 tested) in a region where 44-73% prevalence was found 9 years before. Collected miracidia were subjected to an in vitro test(More)
T follicular helper cells (Tfh cells) play a pivotal role in germinal center reactions, which require B cell lymphoma 6 (Bcl6) transcription factor. To analyze their relationships with other effector T cell lineages and their stability in vivo, we developed and analyzed a new Bcl6 reporter mouse alone or together with other lineage reporter systems.(More)
In immune responses, activated T cells migrate to B-cell follicles and develop into follicular T-helper (TFH) cells, a recently identified subset of CD4(+) T cells specialized in providing help to B lymphocytes in the induction of germinal centres. Although Bcl6 has been shown to be essential in TFH-cell function, it may not regulate the initial migration(More)
BACKGROUND Schistosomiasis has reemerged in China, threatening schistosomiasis elimination efforts. Surveillance methods that can identify locations where schistosomiasis has reemerged are needed to prevent the further spread of infections. METHODS AND PRINCIPAL FINDINGS We tested humans, cows, water buffalo and the intermediate host snail, Oncomelania(More)
Viral infection triggers induction of type I interferons (IFNs), which are critical mediators of innate antiviral immune response. Mediator of IRF3 activation (MITA, also called STING) is an adapter essential for virus-triggered IFN induction pathways. How post-translational modifications regulate the activity of MITA is not fully elucidated. In expression(More)
7 Abstract 8 Estimation of aerosol loadings is of great importance to the studies on global climate changes. The current Moderate-Resolution Imaging 9 Spectroradiometer (MODIS) aerosol estimation algorithm over land is based on the " dark-object " approach, which works only over densely 10 vegetated (" dark ") surfaces. In this study, we develop a new(More)
Recent accumulating evidence has indicated that ZNF804A (zinc finger protein 804A) may be one of the most robustly implicated genes in schizophrenia. In this report, we examined ZNF804A single nucleotide polymorphisms (SNPs) encompassing exon 4 by performing an association study that used a Han Chinese sample comprised of 492 schizophrenia patients and 516(More)
Reversible ubiquitin modification of cell signaling molecules has emerged as a critical mechanism by which cells respond to extracellular stimuli. Although ubiquitination of TGF-β-activated kinase 1 (TAK1) is critical for NF-κB activation in T cells, the regulation of its deubiquitination is unclear. We show that USP18, which was previously reported to be(More)
