Prior to the experiments, HEPES-buffered Ringer’s solution (in some cases EBM-2 medium) was added to empty wells of a 12-well plate (Costar). Filter inserts, containing confluent monolayers of CD34+-ECs, were subsequently placed in the 12-well plate, filled with compound solution containing the fluorescent integrity marker Lucifer Yellow (20 µM; Life Technologies), and then placed on an orbital shaker. After 1 h, filter inserts were withdrawn from the receiver compartment. Aliquots from the donor solution were taken at the beginning and at the end of the experiments and the fluorescence was quantified. At least three inserts with cells and three without cells were tested in each permeability measurement. Fluorescence detection was carried out on a Synergy H1 multiplates reader (Biotek) using the following excitation/emission wavelength (nm) settings: 432/538; 490/516; 542/570 for Lucifer yellow, Fluorescein Na and Cy3-Human Serum Albumin and Human IgG respectively.
To obtain a concentration-independent transport parameter, the clearance principle was used. The increment in cleared volume was calculated by dividing the amount of compound in the receiver compartment by the drug concentration in the donor compartment [7] (link). The volume cleared was plotted versus time and the slope estimated by linear regression analysis. The slope of the clearance curve with inserts alone and inserts with cells is equal to PSf and PSt, respectively, where PS (microliters/minute) is the permeability surface area (square centimeter) product. The PS-value for endothelial monolayer (PSe) was calculated. To generate the endothelial permeability coefficient, Pe (cm/min), the PSe value was divided by the surface area of the filter (A in cm2) insert using the following equation: Pe = [1/PSt−1/PSf]−1/A. To assess possible adsorption to plastics and non-specific binding to cells, the mass balance (%) was calculated from the amount of compound recovered in both compartments at the end of the experiment divided by the total amount added in the donor compartment at time zero. For Pe determination, mass balance value should be between 80% and 120%.

The starting concentration of the radioisotope in the hemolymph half chamber (DPM ⋅ l–1) was divided by the concentration of Ca2+ (10 mM) in the Ringer solution to give the specific activity in DPM ⋅ (mmol Ca2+)–1.
The amount of DPM from the 45Ca accumulated in the shell half chamber at each time point was multiplied by 80 to achieve the total DPM in the 4 ml volume. The total amount of Ca2+ (mM) transferred across the OME was then calculated from the total DPM using the specific activity according to Eq. 2.
The slope of the Ca2+ accumulation across 90 min was determined and the transport rate was expressed as nM ⋅ min–1.
The permeability of the paracellular pathways was described by the apparent permeability (Papp) of 3H-mannitol across the OME, which was calculated using Eq. 3
in which dQ ⋅ dt–1 describes the appearance of 3H-mannitol on the shell side (mol ⋅ s–1), Ac the surface area of the chamber opening (0.75 cm2) and C0 the initial concentration of 3H-mannitol on the hemolymph side (mol ⋅ ml–1).

Mice were divided in six groups of six mice. Colonization was achieved by intragastric gavage with 200 μl of inoculum once per day for three consecutive days. The experimental design and the different groups are summarized in Figure 1A. The control group was comprised of 3-week old SPF mice (SPF3w) gavaged with Ringer’s solution containing L-cysteine. A group of 3-week old and a group of 8-week old SPF mice were inoculated without prior treatment and were respectively designated as SPF 3-week recipients (SPF3w-r) and SPF 8-week recipients (SPF8w-r). A group of 3-week old SPF mice was subjected to a bowel cleansing with 1.2 ml of PEG solution before the inoculation of Lepob fecal microbiota and is later referred as PEG-recipients (PEG-r). PEG solution contained PEG 3350 (77.5 g/L), sodium chloride (1.9 g/L), sodium sulfate (7.4 g/L), potassium chloride (0.98 g/L) and sodium bicarbonate (2.2 g/L) diluted in sterile tap water and was divided in five equal doses that were administered by oral gavage at 30 min intervals after a 2 h fast. Lepob fecal microbiota transfer was performed 6 h after the last PEG administration. The endogenous intestinal microbiota of a last group of 3-week old SPF mice was depleted by gavage with broad spectrum antibiotics over 7 days (Reikvam et al., 2011 (link)). The antibiotics solution consisted of ampicillin, neomycin, metronidazole and vancomycin diluted in sterile water. Mice received 200 mg/kg of ampicillin, neomycin and metronidazole and 100 mg/kg of vancomycin once a day. After 7 days, the residual luminal microbiota and the antibiotics were flushed out using 1.5 ml of PEG solution. The PEG solution and the inoculum were prepared and administered as previously described and provided 24 h after the last antibiotics gavage. This group is later referred as antibiotics and PEG-treated recipients (AbxPEG-r). Eight-week old GF mice were inoculated with Lepob fecal microbiota immediately after the opening of their sterile shipping container. This group is later referred as Germ-Free-recipients (GF-r). Mice were transferred into clean cages several times over the course of bowel cleansing treatment and Lepob fecal microbiota administration.

Stage V–VI oocytes were isolated from adult female Xenopus laevis (Nasco) by partial ovariectomy under Tricaine (1% solution) anaesthesia and were defolliculated by treatment at room temperature (21–23°C) for up to 2 h, with ∼2 mg/ml collagenase (Type II; Worthington Biochemicals or Type I; GIBCO BRL) in nominally Ca2+-free oocyte Ringer's solution containing (mM): 82.5 NaCl, 2 KCl, 1 MgCl2, 5 HEPES, pH 7.5). Defolliculated oocytes were rinsed extensively with Ca2+-free Ringer's (three to five washes, 50-ml each), and then incubated at 18°C for several hours in Ringer's with 1.8 mM Ca2+ and 50 μg/ml gentamycin (GIBCO BRL) before they were pressure-injected (nanojet; Drummond Scientific) with cRNAs. Injection pipettes were pulled (PP83; Narishige) from glass capillaries (3-000-203-G/X; Drummond Scientific) and their tips were broken to an internal diameter of 10–20 μm. Usually, and unless otherwise specified, 2.5 ng of each cRNA, premixed if for coexpression, in a constant total volume of 50 nl, were injected per oocyte. Injected oocytes were further incubated at 18°C for 2–3 d before they were used for recording or for preparation of membranes.

Tyrode solution contained (in mM) 140 NaCl, 5 KCl, 2.5 CaCl2, 2 MgCl2, and 10 HEPES. The standard extracellular solution for voltage-clamp experiments contained (in mM) 140 TEA-methane-sulfonate, 2.5 CaCl2, 2 MgCl2, 1 4-aminopyridine, 10 HEPES, and 0.002 tetrodotoxin. For the experiments described in Figs. 1 and 2, the extracellular solution also contained 0.33% DMSO. The standard pipette solution contained (in mM) 120 K-glutamate, 5 Na2-ATP, 5 Na2-phosphocreatine, 5.5 MgCl2, 5 glucose, and 5 HEPES. For measurements of rhod-2 Ca2+ transients, it also contained 15 EGTA, 6 CaCl2, and 0.1 rhod-2. For measurements with fluo-4, isolated muscle fibers were incubated for 30 min in the presence of Tyrode solution containing 10 μM fluo-4 AM. All solutions were adjusted to pH 7.20. The Ringer solution used for muscle force measurements contained (in mM) 140 NaCl, 6 KCl, 3 CaCl2, 2 MgCl2, and 10 HEPES, adjusted to pH 7.40.
Probenecid was prepared as a 0.3 M aliquoted stock solution in DMSO and used in the extracellular solution at 0.5, 1, or 2 mM. Carbenoxolone was prepared as a 10 mM stock solution in the extracellular solution and used at 0.1 mM. These concentrations were chosen on the basis of their effectiveness and wide use to block Panx1 channels throughout the literature (e.g., Dahl et al., 2013 (link)). When testing the effect of either probenecid or carbenoxolone using the preincubation protocol (Figs. 1 and 2), fibers were bathed in the drug-containing extracellular solution from the beginning of the intracellular dialysis with the rhod-2-containing solution (i.e., 30 min before taking measurements). The 10panx1 peptide and the scrambled control peptide (10panx1SCr) were tested under the same conditions at 200 µM while the P2Y2 antagonist AR-C 118925XX was tested at 10 µM. All chemicals and drugs were purchased from Sigma-Aldrich, except for tetrodotoxin (Alomone Labs), rhod-2 and fluo-4 (Thermo Fisher Scientific), and AR-C 118925XX (TOCRIS—Bio-Techne).
In vitro fluorescence measurements using droplets of a solution containing (in mM) 120 K-glutamate, 10 HEPES, 15 EGTA, 6 CaCl2, and 0.1 rhod-2, with or without probenecid, showed that fluorescence intensity in the presence of 1 mM probenecid corresponded to 1.09 ± 0.12% (n = 6) the intensity in the absence of probenecid, excluding an interaction of the drug with the dye to explain the effect on resting fluorescence in muscle fibers.

Electrically stimulated isolated extensor digitorum longus (EDL) muscles were used to assess the effect of probenecid on force development. For this, 8-wk-old OF1 male mice were anesthetized by isoflurane inhalation and killed by cervical dislocation, and EDL muscles were removed. Force measurements were performed using the 1205A Isolated Muscle System from Aurora Scientific. The EDL muscle was mounted in the experimental chamber in the presence of air-bubbled Ringer solution (see Solutions) maintained at 25°C. The muscle was stretched to the optimum length for the production of maximum isometric twitch force triggered by a supra-maximum 0.2-ms-long electrical stimulation. From this time point, the muscle was repeatedly stimulated by a series of five such electrical stimulations applied at 0.1 Hz, every 5 min, throughout the experiment. Force measurements were performed in response to 60 Hz supramaximum tetanic trains of stimulations of 0.5 s total duration, applied every 15 min. Following the first tetanic response, the Ringer solution was exchanged for the DMSO-containing Ringer with or without probenecid. Force values were normalized by the weight of the muscle.

For all cell assays, HepG2 at passages below 10 were seeded in the gel at a final concentration of 1 × 106 cells/ml and experiments carried out for n = 3. Proliferation of HepG2 in culture was assessed with a CellTiter Blue assay (Promega Corporation, Fitchburg, United States of America). 100 µl of medium with 20 µl CellTiter Blue were added to each well and incubated at 37°C for 3 h. Fluorescence intensity of the supernatant was read with an Infinite M Plex plate reader (Tecan Group AG, Männedorf, Switzerland). Cell viability was determined by staining for live cells with fluorescein diacetate (Sigma-Aldrich, St. Louis, United States of America) and dead cells with propidium iodide (Carl Roth GmbH + Co. KG, Karlsruhe, Germany) (1:60 diluted in Ringer’s solution). Quantification of viable and dead cells was done in ImageJ (see Supplementary Figure S3).
For the analysis of live cell morphology inside the gels, HepG2 were incubated with 2 µM CellTracker™ Green CMFDA Dye (Thermo Fisher Scientific Inc. Waltham, United States of America) per 10 × 106 cells for 30 min before seeding. Cells retained their fluorescence signal and passed it on to daughter cells for up to 7 days. Before immunofluorescence stains, cells were fixed in 4% paraformaldehyde (Carl Roth GmbH + Co. KG, Karlsruhe, Germany) for 15 min and permeabilized with 0.5% Triton X-100 in PBS (Carl Roth GmbH + Co. KG, Karlsruhe, Germany) for 10 min. Actin filaments were stained for 30 min with Alexa Fluor 488 Phalloidin (1:400 dilution in PBS) (Thermo Fisher Scientific Inc. Waltham, United States of America) and nuclei for 3 min with DAPI (1:800 dilution in PBS) (Sigma Aldrich, St. Louis, United States of America).

The induction of murine HUS by repetitive doses of Stx purified from an O157:H7 EHEC strain 86-24 patient isolate was performed as described previously (18 (link)). Male C57BL/6J wild-type mice aged 10-14 weeks were randomly assigned to one of six groups (sham + vehicle; HUS + vehicle; sham + ibrutinib; HUS + ibrutinib; sham + acalabrutinib; HUS + acalabrutinib) (n = 16 per group). Briefly, mice received low doses of Stx (25 ng/kg BW in 0.9% NaCl; HUS groups) or 0.9% NaCl (sham groups) i.v. on day 0, 3 and 6 and BTKi treatment (ibrutinib, acalabrutinib or vehicle) every 24 h p.o. starting immediately after initial Stx injection. For fluid resuscitation, mice received 800 µl Ringer’s Lactate solution subcutaneously three times daily. Body weight was monitored daily and disease progression was evaluated three times daily using an established HUS score (Supplementary Table S1), in which the disease severity was categorized from 1 = no signs of illness to 5 = dead. Survival was monitored up to day 7 using humane endpoints (18 (link), 19 (link)). Animals were exsanguinated in deep anesthesia (100 mg/kg ketamine; 10 mg/kg xylazine) and perfused with 0.9% NaCl. All in vivo experiments were approved by the regional animal welfare committee and the Thuringian State Office for Consumer Protection (registration number UKJ-20-018) and were performed in accordance with German legislation and the approved guidelines.
