However, biases in discovery and reporting of inversions make it difficult to assess their prevalence and biological importance. Here, we use an approach based on linkage disequilibrium among markers genotyped for samples collected across a transect between contrasting habitats to detect chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in a single locality for the coastal marine snail, Littorina saxatilis. Patterns of diversity in the field and of recombination in controlled crosses provide strong evidence that at least the majority of these rearrangements are inversions. Most show clinal changes in frequency between habitats, suggestive of divergent selection, but only one appears to be fixed for different arrangements in the two habitats. Consistent with widespread evidence for balancing selection on inversion polymorphisms, we argue that a combination of heterosis and divergent selection can explain the observed patterns and should be considered in other systems spanning environmental gradients. article_processing_charge: No author: - first_name: Rui full_name: Faria, Rui last_name: Faria - first_name: Pragya full_name: Chaube, Pragya last_name: Chaube - first_name: Hernán E. full_name: Morales, Hernán E. last_name: Morales - first_name: Tomas full_name: Larsson, Tomas last_name: Larsson - first_name: Alan R. full_name: Lemmon, Alan R. last_name: Lemmon - first_name: Emily M. full_name: Lemmon, Emily M. last_name: Lemmon - first_name: Marina full_name: Rafajlović, Marina last_name: Rafajlović - first_name: Marina full_name: Panova, Marina last_name: Panova - first_name: Mark full_name: Ravinet, Mark last_name: Ravinet - first_name: Kerstin full_name: Johannesson, Kerstin last_name: Johannesson - first_name: Anja M full_name: Westram, Anja M id: 3C147470-F248-11E8-B48F-1D18A9856A87 last_name: Westram orcid: 0000-0003-1050-4969 - first_name: Roger K. full_name: Butlin, Roger K. last_name: Butlin citation: ama: Faria R, Chaube P, Morales HE, et al.

Yet within these networks, neurons can exhibit high connection probabilities, suggesting that cell-intrinsic factors, not proximity, determine connectivity. Here, we identify ephrin-B3 (eB3) as a factor that determines synapse density by mediating a cell-cell competition that requires ephrin-B-EphB signaling. In a microisland culture system designed to isolate cell-cell competition, we find that eB3 determines winning and losing neurons in a contest for synapses. In a Mosaic Analysis with Double Markers (MADM) genetic mouse model system in vivo the relative levels of eB3 control spine density in layer 5 and 6 neurons. MADM cortical neurons in vitro reveal that eB3 controls synapse density independently of action potential-driven activity. Our findings illustrate a new class of competitive mechanism mediated by trans-synaptic organizing proteins which control the number of synapses neurons receive relative to neighboring neurons. article_number: e41563 article_processing_charge: No author: - first_name: Nathan T. full_name: Henderson, Nathan T. last_name: Henderson - first_name: Sylvain J. full_name: Le Marchand, Sylvain J. last_name: Le Marchand - first_name: Martin full_name: Hruska, Martin last_name: Hruska - first_name: Simon full_name: Hippenmeyer, Simon id: 37B36620-F248-11E8-B48F-1D18A9856A87 last_name: Hippenmeyer orcid: 0000-0003-2279-1061 - first_name: Liqun full_name: Luo, Liqun last_name: Luo - first_name: Matthew B. full_name: Dalva, Matthew B. last_name: Dalva citation: ama: Henderson NT, Le Marchand SJ, Hruska M, Hippenmeyer S, Luo L, Dalva MB.

Here, we quantified timing variability of individual promoters responding to sublethal antibiotic stress using fluorescent reporters, microfluidics, and time‐lapse microscopy. We identified lower and upper bounds that put definite constraints on timing variability, which varies strongly among promoters and conditions. Timing variability can be interpreted using results from statistical kinetics, which enable us to estimate the number of rate‐limiting molecular steps underlying different responses. We found that just a few critical steps control some responses while others rely on dozens of steps. To probe connections between different stress responses, we then tracked the temporal order and response time correlations of promoter pairs in individual cells. Our results support that, when bacteria are exposed to the antibiotic nitrofurantoin, the ensuing oxidative stress and SOS responses are part of the same causal chain of molecular events. In contrast, under trimethoprim, the acid stress response and the SOS response are part of different chains of events running in parallel. Our approach reveals fundamental constraints on gene expression timing and provides new insights into the molecular events that underlie the timing of stress responses. acknowledged_ssus: - _id: Bio article_number: e8470 article_processing_charge: No author: - first_name: Karin full_name: Mitosch, Karin id: 39B66846-F248-11E8-B48F-1D18A9856A87 last_name: Mitosch - first_name: Georg full_name: Rieckh, Georg id: 34DA8BD6-F248-11E8-B48F-1D18A9856A87 last_name: Rieckh - first_name: Mark Tobias full_name: Bollenbach, Mark Tobias id: 3E6DB97A-F248-11E8-B48F-1D18A9856A87 last_name: Bollenbach orcid: 0000-0003-4398-476X citation: ama: Mitosch K, Rieckh G, Bollenbach MT.

Immune priming is one such example, where a previous encounter with a pathogen confers enhanced protection upon secondary challenge, resulting in reduced pathogen load (i.e., resistance) and improved host survival. However, an initial encounter might also enhance tolerance, particularly to less virulent opportunistic pathogens that establish persistent infections. In this scenario, individuals are better able to reduce the negative fecundity consequences that result from a high pathogen burden. Finally, previous exposure may also lead to life‐history adjustments, such as terminal investment into reproduction.\r\n Using different Drosophila melanogaster host genotypes and two bacterial pathogens, Lactococcus lactis and Pseudomonas entomophila, we tested whether previous exposure results in resistance or tolerance and whether it modifies immune gene expression during an acute‐phase infection (one day post‐challenge). We then asked whether previous pathogen exposure affects chronic‐phase pathogen persistence and longer‐term survival (28 days post‐challenge).\r\n \ We predicted that previous exposure would increase host resistance to an early stage bacterial infection while it might come at a cost to host fecundity tolerance. We reasoned that resistance would be due in part to stronger immune gene expression after challenge. We expected that previous exposure would improve long‐term survival, that it would reduce infection persistence, and we expected to find genetic variation in these responses.\r\n We found that previous exposure to P. entomophila weakened host resistance to a second infection independent of genotype and had no effect on immune gene expression. Fecundity tolerance showed genotypic variation but was not influenced by previous exposure. However, L. lactis persisted as a chronic infection, whereas survivors cleared the more pathogenic P. entomophila infection.\r\n \ To our knowledge, this is the first study that addresses host tolerance to bacteria in relation to previous exposure, taking a multi‐faceted approach to address the topic. Our results suggest that previous exposure comes with transient costs to resistance during the early stage of infection in this host–pathogen system and that infection persistence may be bacterium‐specific.\r\n" article_processing_charge: No article_type: original author: - first_name: Megan full_name: Kutzer, Megan id: 29D0B332-F248-11E8-B48F-1D18A9856A87 last_name: Kutzer orcid: 0000-0002-8696-6978 - first_name: Joachim full_name: Kurtz, Joachim last_name: Kurtz - first_name: Sophie A.O. full_name: Armitage, Sophie A.O. last_name: Armitage citation: ama: Kutzer M, Kurtz J, Armitage SAO.

There is a crucial need for pharmacological ABCB1 and ABCG2 inhibition protocols for a more effective treatment of brain diseases. In the present study, seven marketed drugs (osimertinib, erlotinib, nilotinib, imatinib, lapatinib, pazopanib, and cyclosporine A) and one nonmarketed drug (tariquidar), with known in vitro ABCB1/ABCG2 inhibitory properties, were screened for their inhibitory potency at the BBB in vivo. Positron emission tomography (PET) using the model ABCB1/ABCG2 substrate [11C]erlotinib was performed in mice. Tested inhibitors were administered as i.v. bolus injections at 30 min before the start of the PET scan, followed by a continuous i.v. infusion for the duration of the PET scan. Five of the tested drugs increased total distribution volume of [11C]erlotinib in the brain (VT,brain) compared to vehicle-treated animals (tariquidar, + 69%; erlotinib, + 19% and +23% for the 21.5 mg/kg and the 43 mg/kg dose, respectively; imatinib, + 22%; lapatinib, + 25%; and cyclosporine A, + 49%). For all drugs, increases in [11C]erlotinib brain distribution were lower than in Abcb1a/b(−/−)Abcg2(−/−) mice (+149%), which suggested that only partial ABCB1/ABCG2 inhibition was reached at the mouse BBB. The plasma concentrations of the tested drugs at the time of the PET scan were higher than clinically achievable plasma concentrations. Some of the tested drugs led to significant increases in blood radioactivity concentrations measured at the end of the PET scan (erlotinib, + 103% and +113% for the 21.5 mg/kg and the 43 mg/kg dose, respectively; imatinib, + 125%; and cyclosporine A, + 101%), which was most likely caused by decreased hepatobiliary excretion of radioactivity. Taken together, our data suggest that some marketed tyrosine kinase inhibitors may be repurposed to inhibit ABCB1 and ABCG2 at the BBB. From a clinical perspective, moderate increases in brain delivery despite the administration of high i.v. doses as well as peripheral drug–drug interactions due to transporter inhibition in clearance organs question the translatability of this concept. article_processing_charge: No author: - first_name: Alexander full_name: Traxl, Alexander last_name: Traxl - first_name: Severin full_name: Mairinger, Severin last_name: Mairinger - first_name: Thomas full_name: Filip, Thomas last_name: Filip - first_name: Michael full_name: Sauberer, Michael last_name: Sauberer - first_name: Johann full_name: Stanek, Johann last_name: Stanek - first_name: Stefan full_name: Poschner, Stefan last_name: Poschner - first_name: Walter full_name: Jäger, Walter last_name: Jäger - first_name: Viktoria full_name: Zoufal, Viktoria last_name: Zoufal - first_name: Gaia full_name: Novarino, Gaia id: 3E57A680-F248-11E8-B48F-1D18A9856A87 last_name: Novarino orcid: 0000-0002-7673-7178 - first_name: Nicolas full_name: Tournier, Nicolas last_name: Tournier - first_name: Martin full_name: Bauer, Martin last_name: Bauer - first_name: Thomas full_name: Wanek, Thomas last_name: Wanek - first_name: Oliver full_name: Langer, Oliver last_name: Langer citation: ama: Traxl A, Mairinger S, Filip T, et al.

However, whether this is the only signaling mode mediating lateral inhibition remains unclear. Here we show that in zebrafish oogenesis, a group of cells within the granulosa cell layer at the oocyte animal pole acquire elevated levels of the transcriptional coactivator TAZ in their nuclei. One of these cells, the future micropyle precursor cell (MPC), accumulates increasingly high levels of nuclear TAZ and grows faster than its surrounding cells, mechanically compressing those cells, which ultimately lose TAZ from their nuclei. Strikingly, relieving neighbor-cell compression by MPC ablation or aspiration restores nuclear TAZ accumulation in neighboring cells, eventually leading to MPC re-specification from these cells. Conversely, MPC specification is defective in taz−/− follicles. These findings uncover a novel mode of lateral inhibition in cell fate specification based on mechanical signals controlling TAZ activity. acknowledged_ssus: - _id: Bio - _id: EM-Fac - _id: LifeSc acknowledgement: We thank Roland Dosch, Makoto Furutani-Seiki, Brian Link, Mary Mullins, and Masazumi Tada for providing transgenic and/or mutant zebrafish lines; Alexandra Schauer, Shayan Shami-Pour, and the rest of the Heisenberg lab for technical assistance and feedback on the manuscript; and the Bioimaging, Electron Microscopy, and Zebrafish facilities of IST Austria for continuous support.

Hosts can alter their strategy towards pathogens during their lifetime, i.e., they can show phenotypic plasticity in immunity or life history. Immune priming is one such example, where a previous encounter with a pathogen confers enhanced protection upon secondary challenge, resulting in reduced pathogen load (i.e. resistance) and improved host survival. However, an initial encounter might also enhance tolerance, particularly to less virulent opportunistic pathogens that establish persistent infections. In this scenario, individuals are better able to reduce the negative fitness consequences that result from a high pathogen load. Finally, previous exposure may also lead to life history adjustments, such as terminal investment into reproduction. 2. Using different Drosophila melanogaster host genotypes and two bacterial pathogens, Lactococcus lactis and Pseudomonas entomophila, we tested if previous exposure results in resistance or tolerance and whether it modifies immune gene expression during an acute-phase infection (one day post-challenge). We then asked if previous pathogen exposure affects chronic-phase pathogen persistence and longer-term survival (28 days post-challenge). 3. We predicted that previous exposure would increase host resistance to an early stage bacterial infection while it might come at a cost to host fecundity tolerance. We reasoned that resistance would be due in part to stronger immune gene expression after challenge. We expected that previous exposure would improve long-term survival, that it would reduce infection persistence, and we expected to find genetic variation in these responses. 4. We found that previous exposure to P. entomophila weakened host resistance to a second infection independent of genotype and had no effect on immune gene expression. Fecundity tolerance showed genotypic variation but was not influenced by previous exposure. However, L. lactis persisted as a chronic infection, whereas survivors cleared the more pathogenic P. entomophila infection. 5. To our knowledge, this is the first study that addresses host tolerance to bacteria in relation to previous exposure, taking a multi-faceted approach to address the topic. Our results suggest that previous exposure comes with transient costs to resistance during the early stage of infection in this host-pathogen system and that infection persistence may be bacterium-specific. article_processing_charge: No author: - first_name: Megan full_name: Kutzer, Megan id: 29D0B332-F248-11E8-B48F-1D18A9856A87 last_name: Kutzer orcid: 0000-0002-8696-6978 - first_name: Joachim full_name: Kurtz, Joachim last_name: Kurtz - first_name: Sophie A.O. full_name: Armitage, Sophie A.O. last_name: Armitage citation: ama: 'Kutzer M, Kurtz J, Armitage SAO.
