Induction of T helper 2 cell responses against Schistosoma mansoni eggs in the murine intestine
T helper 2 (Th2) cell responses typify the immune response to parasitic organisms, which frequently invade the intestine. Dendritic cells (DCs) are considered vital for the induction of Th2 responses as they present parasite- derived antigens to naive T cells in draining lymph nodes. However, the identities of the DC populations responsible for priming Th2 cells in the intestine are still unclear. We developed an experimental immunization protocol to deliver Schistosoma mansoni eggs into the intestine. During live infection by the parasite, these eggs cause intestinal damage, granuloma formation, tissue fibrosis and strong type 2 immune responses.
Many aspects of type 2 immunity are controlled by the transcription factor IRF4 and we observed that intestinal Th2 responses against Schistosoma mansoni eggs did not develop in the draining lymph nodes in the absence of IRF4+ DCs. IRF4f/f CD11c-cre positive mice had fewer CD11b-expessing migrating DCs, and fewer parasite antigen-carrying DCs were present in the mesenteric lymph nodes (MLNs) draining the small intestine and colon. However, transfer of antigen-loaded IRF4-deficient DCs directly into the MLN revealed that these cells could induce antigen-specific Th2 responses, suggesting that IRF4 controlled the migration of CD11b-expessing DCs rather than their Th2 inducing capacity.
Furthermore, immature DCs from the intestinal lamina propria, and semi-mature DCs from lymph were sufficient to prime antigen-specific Th2 responses against egg antigens when transferred into naive recipient mice. This induction was dependent on MHCII expression but not on the production of IL-4 by the transferred DCs, indicating that conventional intestinal DCs are fully capable of inducing Th2 responses against S. mansoni egg antigens upon transfer.
Further analysis of migratory small intestinal and colonic lymph DCs revealed that distinct subsets of CD11b-expressing DCs were sufficient for the induction of Th2 responses in the small intestine and colon. CD11b+CD103+ DCs transported parasite antigen from the small intestine, whereas CD11b+CD103- DCs performed this role in the colon. Of note, these same small intestinal and colonic DC subsets were also the populations that were most efficient at priming antigen-specific Th2 responses in vivo.
Thus, we have not only identified that IRF4-dependent CD11b-expressing DCs are specialized to drive Th2 responses in the intestine but have also revealed that different DC subsets promote Th2 responses in the small intestine and colon. These findings not only advance our knowledge of intestinal Th2 responses against parasite antigens but also reveal a hitherto unappreciated functional heterogeneity among intestinal DCs, which could also be relevant for other tissue- specific intestinal conditions like Crohn’s disease, ulcerative colitis and celiac disease
Robust estimation of bacterial cell count from optical density
Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples
Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

German General Social Survey (ALLBUS) - Cumulation 1980-2010
ALLBUS (GGSS - the German General Social Survey) is a biennial trend survey based on random samples of the German population. Established in 1980, its mission is to monitor attitudes, behavior, and social change in Germany. Each ALLBUS cross-sectional survey consists of one or two main question modules covering changing topics, a range of supplementary questions and a core module providing detailed demographic information. Additionally, data on the interview and the interviewers are provided as well. Key topics generally follow a 10-year replication cycle, many individual indicators and item batteries are replicated at shorter intervals. ALLBUS/GGSS 1980-2010 compiles all of the time series in the ALLBUS program (i.e. it contains data for all questions that have been surveyed in at least two of the so far 17 cross-sectional surveys).Cumulated ALLBUS/GGSS 1980-2010 is an English translation of the original German survey Cumulated ALLBUS 1980-2010.

Where Brain, Body and World Collide
The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pt < 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy sqrt{s} = 7 TeV using an integrated luminosity of 2.2 nb^{-1}. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark-antiquark pairs
