Description
The prevalence of immune-mediated diseases such as allergies and autoimmune diseases is on the rise in the developed world. Microbial exposure is known to modulate the risk for these diseases. In order to explore differences in the gene expression patterns induced in utero in infants born in contrasting standards of living and hygiene, we collected umbilical cord blood RNA samples from full-term newborn infants born with normal vaginal delivery in Finland (modern society), Estonia (rapidly developing society) and the Republic of Karelia, Russia (poor economical conditions). Transcriptomic profiles were analyzed using whole genome microarrays including gender, gestational age, birth month and HLA allele genotype as confounding variables in the analysis. The data revealed that the whole blood transcriptome of Finnish and Estonian neonates differ from their Karelian counterparts. Samples from Karelian infants had an increase in transcripts associated with LPS induction and bacterial sepsis observed in 1-year-old infants in earlier studies. The results suggest exposure to toll like receptor (TLR) ligands and a more matured immune response in infants born in Petrozavodsk compared to the Finnish and Estonian infants. These results further support the concept of a conspicuous plasticity in the developing immune system: the environmental factors that play a role in the susceptibility/protection towards immune-mediated diseases begin to shape the neonatal immunity already in utero and direct the maturation of both the adaptive and the innate immune responses in accordance with the surrounding microbial milieu.

Description
Sensory functions of the vagus nerve are critical for specific aware perceptions and for monitoring visceral functions in the cardio-pulmonary and gastrointestinal systems. Here we present a comprehensive identification, classification, and validation of the neuron types in the neural crest (jugular) and placode (nodose) derived vagal ganglia by single cell transcriptomic (scRNA-seq) analysis. Our results reveal major differences between neurons derived from different embryonic origins. Jugular neurons exhibit fundamental similarities to the somatosensory spinal neurons, including major types such as C-low threshold mechanoreceptors (C-LTMRs), A-LTMRs, Ad-nociceptors, cold-, and mechano-heat C-nociceptors. In contrast, the nodose ganglion contains 18 distinct types dedicated to surveying the physiological state of the internal body. Our results reveal a vast diversity of vagal neuron types including many previously unanticipated types as well as proposed types that are consistent with chemoreceptors, nutrient detectors, baroreceptors, and stretch and volume mechanoreceptors of the respiratory, gastrointestinal, and cardiovascular systems. Overall design: Single-cell RNA-seq from 1896 vagal ganglion cells derived from wild-type and Vglut2Cre-Tomato animals originating from four replicates and consisting of the neuronal and non-neuronal cells that make up the ganglionic tissue.

Description
Objective: Physical exercise and vitamin E are considered effective treatments of nonalcoholic fatty liver and other metabolic diseases. However, vitamin E has also been shown to interfere with the adaptation to exercise training, in particular for the skeletal muscle. Here, we studied the hypothesis that vitamin E also interferes with the metabolic adaptation of the liver to acute exercise.

Description
Muscle contraction during exercise is the major stimulus for the release of peptides and proteins (myokines) that are supposed to take part in the benefical adaptation to exercise. We hypothesize that application of an in vitro exercise stimulus as electric pulse stimulation (EPS) to human myotubes enables the investigation of the human muscle secretome in a clearly defined model. We applied EPS for 24 h to primary human myotubes and studied the whole genome-wide transcriptional response and as well as the release of candidate myokines. We observed 183 differentially regulated transcripts with fold-changes > 1.3. The transcriptional response resembles several properties of the in vivo situation in the skeletal muscle after endurance exercise, namely significant enrichment of pathways associated with interleukin and chemokine signaling, lipid metabolism, and anti-oxidant defense; notably without increased release of creatin kinase.

Description
We explore the heterogeneity of mouse thoracic ganglia demonstrating the presence of an unexpected variety of cell-types and identify specialized populations of nipple- and pilo-erector muscle neurons. These neurons extend axonal projections and are born amongst other neurons during embryogenesis, but remain unspecialized until target organogenesis occurs postnatally. Target innervation and cell-type specification is coordinated by an intricate acquisition of unique combinations of growth factor receptors and the initiation of expression of concomitant ligands by the nascent erector muscles. Overall design: RNA-seq analysis of 298 single sympathetic neuronal cells from the mouse thoracic ganglion
Publication Title
Visceral motor neuron diversity delineates a cellular basis for nipple- and pilo-erection muscle control.

Description
Background/aims: Serum concentrations of the hepatokine fibroblast growth factor (FGF) 21 are elevated in obesity, type2 diabetes, and the metabolic syndrome. We asked whether FGF21 levels differ between subjects with metabolically healthy vs. unhealthy obesity (MHO vs. MUHO) opening the possibility that FGF21 is a crosstalker between liver and adipose tissue in MUHO. Furthermore, we studied the effects of chronic FGF21 treatment on adipocyte differentiation, lipid storage, and adipokine secretion.
