This is not least due to the lack of standardized methods and reliable validated biomarkers for immunotoxic effects. The experimental set up was designed to analyze the compound specific response of zebrafish embryos to two immunomodulative reference substances  clobetasol propionate CP  CAS 25122 46 7 and imiquimod IMQ  CAS 99011 02 6  on the global level of gene expression. The obtained results were used to i identify potential biomarker candidates for the assessment of immunotoxic MoAs  ii identify compound specific molecular signatures  iii evaluate the reliability of data acquisition using OMICs coupled approaches and iv to assess the suitability of the zebrafish embryo as an alternative model for the human representative investigation of psoriatic effects. For this  the transcriptomic profiles of embryos were bioinformatically analysed subsequent to an CP induced immunosuppression in absence or presence of an IMQ induced immune challenge  i.e. the simulation of a resting and an activated immune system.   In a modified version of the zebrafish embryo toxicity test OECD 236  15 fertilized eggs were exposed to either CP 250 nM or to IMQ 4000 nM or to a combination of both under semi static conditions. Exposure to CP started at 2 hpf until 72 hpf. Exposure to IMQ started at 48 hpf until 72 hpf. Untreated embryos reared in medium without xxx nor IMQ dissolved was used as a negative control. All conditions comprised three biological replicates. Medium was exchanged on a daily basis by renewing half its volume. Occurrence of morphological changes and indicators of lethality as described in the OECD test guideline 236 were examined microscopically on a daily basis. At 72 hpf  all larvae were pooled for each sample for RNA extraction using a NucleoSpin RNA/Protein kit Macherey Nagel following the manufacturer's protocol. RNA quality was assessed with a 2100 Bioanalyzer system Agilent before coding RNA was purified PolyA selection with TruSeq RNA Library Prep Kit v2 and sequenced on an Illumina NovaSeq 6000 System Illumina in 150 bp paired end mode  producing a minimum of 30 million reads per sample. Adapter sequences were removed with trimmomatic and sequences were aligned to the Danio rerio reference genome GRCz11 with STAR. Counting of feature mapped reads was performed through featureCounts. Library gene count tables were then merged to a single count matrix as input for differential gene expression analysis with DESeq2.", "ENA FIRST PUBLIC:2023 12 01|ENA LAST UPDATE:2023 12 01", null, "Protocols: At 72 hpf  for each sample  all 15 zebrafish embryos were picked from the glass well and carefully transferred to a 1.5 ml low binding Eppendorf tube. Excessive liquid was removed and tubes were placed on ice to euthanize the embryos. For detailed information about embryonic incubation conditions and husbandry of adult broodstock please refer to the \u201cGrowth protocol\u201d. For detailed information about exposure duration and conditions please refer to the \u201cTreatment protocol\u201d. Adult animal husbandry: All experiments were performed using zebrafish Danio rerio embryos of the wild type strain AB. Adult fish were originally obtained from West Aquarium GmbH  Germany  and were kept in 150 l tanks under flow through conditions at 26 \u00b1 2 \u00b0C and a 12:12 light/dark cycle at the Fraunhofer Institute for molecular biology and applied ecology IME  Schmallenberg  Germany. TetraMin\u00ae Tetra Werke  Germany was used as daily main feed  regularly supplemented with nauplii of Artemia salina. Fish were constantly bred for several generations without xxx between tanks  making the embryos deriving from different spawning groups tanks independent biological replicates. For egg collection  glass spawning trays equipped with whirled cords of green glass pearls to stimulate spawning and covered with wired mesh to prevent cannibalism were put into the tanks the day before tests were started OECD  2013. The morning post  eggs were collected from the trays using a sieve  rinsed with pre tempered system water to remove remaining feces  gathered in glass jars filled with pre tempered aerated system water and stored at a controlled temperature of 26 \u00b1 1 \u00b0C until further use. Fish embryo incubation: Embryos were incubated at a controlled temperature of 26 \u00b1 1\u00b0C and a 14:10 h light/dark cycle artificially created with tubular fluorescent lamps with the lights switched on at 8 am. Medium was refreshed at 24 hpf by renewing half its volume.

For IMQ  a stock solution in acetone with a nominal concentration of 0.1 mg/ml was prepared. For CP  a stock solution in dimethyl sulfoxide DMSO with a nominal concentration of 2.5 mM was prepared. To obtain a test solution with a nominal concentration of 4666 nM IMQ  2242.5 \u00b5l of the IMQ stock solution was added to a glass bottle. To equalize the amount of added acetone amongst all solutions  equal volume of pure acetone without xxx was added to glass bottles for all remaining test solutions. For all test solutions containing 250 nM CP  20 \u00b5l of the CP stock solution was added to the glass bottles post complete evaporation of the acetone and filled with copper reduced tap water in the following referred to as cu red water to a final volume of 200 ml. Test solutions without xxx were prepared alike adding 20 \u00b5l DMSO without xxx. All solutions were sonicated for 30 min at room temperature Sonorex RK 100H  Bandelin  Germany. Final solutions were thus cu red water with 0.01 % DMSO  4666 nM IMQ in cu red water with 0.01 % DMSO  250 nM CP in cu red water with 0.01 % DMSO and 4666 nM IMQ plus 250 nM CP in cu red water with 0.01 % DMSO. Due to a mandatory dilution during the methodological procedure a nominal working concentration of 4000 nM was achieved for IMQ in these solutions. The test solutions were freshly prepared one day prior the start of the experiment and stored at room temperature in the dark. They were constantly aerated and used over the course of the 72 hours exposure experiment. The glass wells for the incubation of the embryos were pre saturated with the respective test solution overnight and renewed at the beginning of the experiment. In order to minimize the differences between replicates and conditions in exposure durations  the selection of embryos was performed in two steps: at 2 hpf  approx. 50 embryos from spawning batches with a minimum fertilization rate \u2265 90 % were transferred to previously overnight saturated glass petri dishes 6 cm diameter refilled with 7 ml of the corresponding test solutions for each replicate and condition. Embryos of the control and the IMQ condition were thus transferred to medium without xxx compound  embryos of the CP and combined CP+IMQ condition were transferred to medium supplemented with 250 nM CP. Once in solution  15 healthy and fertilized embryos  indicated by a well shaped blastodisc between the 128 cell and 1k cell stage of development were selected per replicate and condition for experiments. Embryos were incubated at a controlled temperature of 26 \u00b1 1\u00b0C and a 14:10 h light/dark cycle artificially created with tubular fluorescent lamps with the lights switched on at 8 am. Medium was refreshed at 24 hpf by renewing half its volume. Embryos were inspected microscopically on a daily basis and at the end of the experiment using an OZL 451 stereomicroscope KERN & Sohn  Germany in order to monitor the occurrence of indicators of lethality as defined by the OECD FET test guideline  namely coagulation  lack of somite formation  lack of a heartbeat  non detachment of the tail OECD  2013 as well as further indicators of malformations such as scoliosis  formation of edema or lack of pigmentation. At 47 hpf  embryos were manually dechorionated using two pointy forceps. At 48 hpf  the immune challenge was started by transferring the embryos of the IMQ condition and the combined CP+IMQ condition to the respective test solution supplemented with IMQ. For this and in order to equalized the subsequent dilution of media between replicates and conditions  embryos were gathered in 1 ml of the aged medium and transferred with this volume into newly saturated glass dishes  filled with 6 ml of the corresponding fresh medium. Due to this dilution  a nominal working concentration of 4000 nM IMQ was achieved for the immune challenge. Embryos of the control condition and the CP condition were handled alike but without xxx the type of test solution. RNA was extracted using a NucleoSpin RNA/Protein kit Macherey Nagel  D\u00fcren  Germany.
