Biologics act on downstream type 2 cytokine pathways inhibiting signalling of interleukins (IL) 4, 5 and 13 [<span>1</span>]. A retrospective study in severe asthma patients receiving anti-IL-5 or anti-IL-5Rα showed no difference in clinical outcomes when stratified by baseline BDR. Dupilumab is a monoclonal antibody which targets the alpha subunit of IL4 receptor which in turn inhibits IL4 and IL13 signalling, resulting in reduced exacerbations, improved symptom control and better lung function [<span>2</span>]. We wanted to evaluate the putative relationship between baseline BDR to salbutamol and the lung function response to dupilumab, expressed as either force expiratory volume in 1 s (FEV<sub>1</sub>) or forced mid-expiratory flow (FEF<sub>25-75</sub>).</p><p>Here we assessed patients with uncontrolled severe asthma (EudraCT 2021-005593-25) who had BDR measured at their initial screening visit.

We assessed the spirometry response to either salbutamol or dupilumab calculated as % predicted changes from baseline, as well as relative % change from baseline (post–pre/pre), and absolute change (FEV<sub>1</sub> in L and FEF<sub>25-75</sub> as L/s).

PGD<sub>2</sub> is metabolised and excreted in urine as tetranor-PGDM. We have previously reported urinary tetranor-PGDM as a sensitive biomarker for food allergy (FA) reactions in children [<span>1</span>]. However, the production profile of other lipid mediators in the urine of FA patients remains unknown. Bioactive lipids are produced by enzyme-dependent or independent metabolism of polyunsaturated fatty acids (PUFAs) such as arachidonic acid (AA), linoleic acid (LA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and dihomo-gamma-linolenic acid (DGLA). There are three types of oxidative enzymes for PUFAs: cyclooxygenase (COX), lipoxygenase (LOX) and cytochrome P450 (CYP). The produced lipid mediators regulate inflammation and are extracted mainly in urine, thus their production profile can reflect the inflammatory status of our bodies. In this study, we comprehensively analysed the production profile of lipid mediators in the urine of subjects who received oral food challenge (OFC).</p><p>We collected the same urine samples from subjects as previously reported [<span>1</span>]. Children suspected of having FA who underwent OFC to milk, egg, peanut or sesame were recruited between December 2014 and August 2015, and urine samples were collected before (pre) and 4 h after OFC (post). Of a total of 42 children, 31 were assessed as having positive results (OFC-positive; FA). This study received ethical approval from the Committee, University of Tokyo School of Medicine (2017,10586). All participants provided informed consent.</p><p>Initially, we confirmed that OFC and/or its positivity did not influence urinary pH, or specific gravity, while they did influence the lipid content (Figure 1A). There was no difference in urinary lipid content in children who ingested offending food, suggesting that lipid content may reflect the inflammatory reaction in the body. Next, we analysed the levels of 196 types of lipid metabolites in urine using LC–MS/MS and detected 19 lipid metabolites. These methods are available in the following repository (https://zenodo.org/records/14207617).</p><p>Figure 1B shows the AA metabolites levels in subjects' urine.

The levels of other PGD<sub>2</sub> metabolites, 13,14-dihydro-15-keto-tetranor-PGD<sub>2</sub> and tetranor-PGJM (precursor and non-enzymatic metabolite of tetranor-PGDM, respectively), were also higher in the OFC-positive-post urine. It is well known that mast cells express H-PGDS and produce PGD<sub>2</sub> [<span>2</span>].

However, the role of TRP receptors in UCC is currently unclear. In this study, an interaction between P2X3 receptors on airway bronchial epithelial cells (BECs) and TRPA1 channels on upper airway nerves was explored in vitro as a potential mechanism for UCC (Figure 1A) [&lt;span&gt;1-3&lt;/span&gt;]. It was hypothesised that irritants activating TRP channels can result in ATP release from airway nerves resulting in P2X3 receptor activation on adjacent airway epithelial cells [&lt;span&gt;3-6&lt;/span&gt;]. To investigate the role of TRPA1 channel activation of P2X3 receptors, an indirect in vitro cell model was developed to demonstrate whether activation of TRPA1 channels expressed on neuronal cells result in ATP release that subsequently activates P2X3 receptors on adjacent BECs.&lt;/p&gt;&lt;p&gt;Dorsal root ganglion cells (DRGN, ND8/34 cell line, Sigma), known to express TRPA1 were used as a surrogate for airway neuronal cells [&lt;span&gt;7&lt;/span&gt;]. Functional assays were performed on DRGNs to quantify TRPA1 activation using the TRPA1 specific agonist (JT010) by observing a change in fluorescence measured by [Ca&lt;sup&gt;2+&lt;/sup&gt;]i of 10% or greater from baseline under confocal microscopy. The DRGNs cultured on poly-Lysine coated plates and loaded with FLUO4, were preincubated in the presence or absence of the TRPA1 antagonist HC-030031 (EMD Milipore) and then treated with a TRPA1-specific agonist (JT010 100 nM, Tocris) (&lt;i&gt;n&lt;/i&gt; = 3 experiments). Culture media from the DRGNs cell wells were collected after stimulation and assayed for ATP. ATP release in response to JT010-induced TRPA1 activation and its suppression by the TRPA1-antagonist, HC-030031, were quantified from the cell supernatant on a luminometer using the ATP Bioluminescence Assay Kit HS II (Roche).

Differential gene expression (DEGs) in these samples versus untreated controls were determined using TaqMan rat inflammation array (Thermo Fisher).
