cortex, fusiform gyrus, middle cingulate, postcentral cortex, and insula). This might implicate a subtle difference in the processing of nonspecific emotional stimuli and warrants more research furthering our understanding of neurofunctional alteration in patients with SP.The mitochondrial gene cytochrome-c-oxidase subunit 1 (COI) is useful in many taxa for phylogenetics, population genetics, metabarcoding, and rapid species identifications. However, the phylum Ctenophora (comb jellies) has historically been difficult to study due to divergent mitochondrial sequences and the corresponding inability to amplify COI with degenerate and standard COI “barcoding” primers. As a result, there are very few COI sequences available for ctenophores, despite over 200 described species in the phylum. Here, we designed new primers and amplified the COI fragment from members of all major groups of ctenophores, including many undescribed species. Phylogenetic analyses of the resulting COI sequences revealed high diversity within many groups that was not evident from more conserved 18S rDNA sequences, in particular among the Lobata (Ctenophora; Tentaculata; Lobata). click here The COI phylogenetic results also revealed unexpected community structure within the genus Bolinopsis, suggested new species within the genus Bathocyroe, and supported the ecological and morphological differences of some species such as Lampocteis cruentiventer and similar undescribed lobates (Lampocteis sp. “V” stratified by depth, and “A” differentiated by colour). The newly designed primers reported herein provide important tools to enable researchers to illuminate the diversity of ctenophores worldwide via quick molecular identifications, improve the ability to analyse environmental DNA by improving reference libraries and amplifications, and enable a new breadth of population genetic studies.

T cells play critical roles in the pathogenesis of systemic lupus erythematosus (SLE). Serum-derived exosomes are increased in SLE patients and are correlated with disease severity. The proteins in the T-cell-derived exosomes from SLE patients could play important roles in SLE pathogenesis.

We characterized proteins of SLE T cell-derived exosomes by exosome MACSPlex analysis and proteomics using T-cell supernatants from SLE patients and healthy controls. To study the potential pathogenic functions of the identified exosomal protein, we generated and characterized T-cell-specific transgenic mice that overexpressed the identified protein in T cells.

We identified eosinophil cationic protein (ECP, also named human RNase 3) that was overexpressed in SLE T cell-derived exosomes. T-cell-specific ECP transgenic mice displayed early induction of serum IFN-γ levels and multi-tissue inflammation. The aged T-cell-specific ECP transgenic mice also displayed an increase of follicular helper T cells, plasma B cell, and autoantibodies. Single-cell RNA sequencing (scRNA-seq) also showed the induction of IFN-γ mRNA and inflammatory pathways in ECP transgenic T cells. Remarkably, adoptively transferred ECP-containing exosomes stimulated serum levels of IFN-γ and autoantibodies in the recipient mice. The transferred exosomes infiltrated into multiple tissues of the recipient mice, resulting in hepatitis, nephritis, and arthritis.

ECP overexpression in T cells or T-cell-derived exosomes may be a biomarker and pathogenic factor for human SLE nephritis, hepatitis, and arthritis.

To improve our understanding of this dynamic, we employed multi-locus genotyping to conduct a cross-sectional study of the potential for zoonotic transmission of the protozoan parasite Giardia duodenalis among humans, household associated livestock and dogs, and black and gold howler monkeys (Alouatta caraya) in the Corrientes Province of Argentina. We found Giardia prevalence to be highest in howler monkeys (90.3% (47/52)), followed by humans (61.1% (22/36)), dogs (44.4% (16/36)), and cattle (41.9% (18/43)). We further established that howler monkeys exclusively harbored strains of assemblage B (100%) while humans were infected with either assemblage A (13.3%) or B (80%) or A and B (6.7%), and cattle and dogs were infected with either assemblage A (cattle, 94.1%; dogs, 80%)), A and C (10%), or their host-adapted assemblage (cattle, 5.9%; dogs, 10%). Our finding of G. duodenalis in both humans and domesticated animals (assemblage A) and humans and wild primates (assemblage B) suggests that cross-species transmission of multiple assemblages of G. duodenalis may occur in rural complexes such as northern Argentina where people, domesticated animals, and wildlife overlap. We further highlight the need to investigate the implications of these results for human health, the economics of livestock production, and wildlife conservation in this and similar systems.We would like to comment on the interesting paper by Safoora Fatima et al of the Canadian Early Arthritis Cohort (CATCH), on the Health Assessment Questionnaire at One Year Predicts All-Cause Mortality in Patients With Early Rheumatoid Arthritis. (1) The conclusion of their paper showed that higher HAQ score and DAS28 at 1 year are significantly associated with all-cause mortality in a large early RA cohort.Although the physiological meaning of the high potential of mouse embryonic stem cells (ESCs) for meiotic entry is not understood, a rigid safeguarding system is required to prevent ectopic onset of meiosis. PRC1.6, a non-canonical PRC1, is known for its suppression of precocious and ectopic meiotic onset in germ cells and ESCs, respectively. MGA, a scaffolding component of PRC1.6, bears two distinct DNA-binding domains termed bHLHZ and T-box. However, it is unclear how this feature contributes to the functions of PRC1.6. Here, we demonstrated that both domains repress distinct sets of genes in murine ESCs, but substantial numbers of meiosis-related genes are included in both gene sets. In addition, our data demonstrated that bHLHZ is crucially involved in repressing the expression of Meiosin, which plays essential roles in meiotic entry with Stra8, revealing at least part of the molecular mechanisms that link negative and positive regulation of meiotic onset.
