Autoimmune responses are involved in the pathophysiology of IBD, but their underlying pathways and target antigens have not yet been fully elucidated. Methods Autoantigenic targets in IBD were identified after separation of whole cell proteins isolated from neutrophils using two-dimensional electrophoresis and matrix assisted laser desorption ionization - time of flight mass spectrometry-based protein identification of the spots that displayed Western blotting signals with anti-neutrophil cytoplasmic antibody-positive sera. The prevalence of IgG, IgA and secretory IgA [sIgA] to chitinase 3-like protein 1 [CHI3L1] was analysed by enzyme-linked immunosorbent assays using recombinant CHI3L1 in 110 patients with Crohn's disease [CD], 95 with ulcerative colitis [UC], 126 with coeliac disease [CeD] and 86 healthy controls [HCs]. Results The 18-glycosylhydrolase family member CHI3L1 was identified as a neutrophil autoantigenic target. CD patients displayed significantly higher levels of IgG to CHI3L1 than patients with UC and CeD (p < 0.0001, respectively). IgA and sIgA to CHI3L1 was significantly higher in CD than in UC, CeD and HCs [p < 0.0001, respectively]. IgA and sIgA to CHI3L1 demonstrated the highest prevalence in CD [25.5\%, 28/110; and 41.8\%\%, 46/110] compared to HCs [2.3\%, 2/86; and 4.7\%\%, 4/86; p = 0.0015 and p < 0.0001] and are associated with a more complicated progression of CD. Conclusion CHI3L1 is a novel neutrophil autoantigenic target in CD. IgA and sIgA to CHI3L1 may serve as novel markers for CD and may facilitate the serological diagnosis of IBD.}, language = {en} } @misc{SowaMurugaiyanConradetal., author = {Sowa, Mandy and Murugaiyan, Jayaseelan and Conrad, Karsten and Laass, Martin W. and Bogdanos, Dimitrios Petrou and Papp, Maria and R{\"o}diger, Stefan and Roggenbuck, Dirk and Schierack, Peter}, title = {A novel neutrophil autoantigenic target in inflammatory bowel disease}, language = {en} } @misc{JurischkaDinterEfimovaetal., author = {Jurischka, Christoph and Dinter, Franziska and Efimova, Anastasia and Weiss, Romano and Schiebel, Juliane and Schulz, Christian and Fayziev, Bekzodjon and Schierack, Peter and Fischer, Thomas and R{\"o}diger, Stefan}, title = {An explorative study of polymers for 3D printing of bioanalytical test systems}, series = {Clinical Hemorheology and Microcirculation}, volume = {75}, journal = {Clinical Hemorheology and Microcirculation}, number = {1}, issn = {1875-8622}, doi = {10.3233/CH-190713}, pages = {57 -- 84}, abstract = {Background: The 3D printing is relevant as a manufacturing technology of functional models for forensic, pharmaceutical and bioanalytical applications such as drug delivery systems, sample preparation and point-of-care tests. Objective: Melting behavior and autofluorescence of materials are decisive for optimal printing and applicability of the product which are influenced by varying unknown additives. Methods: We have produced devices for bioanalytical applications from commercially available thermoplastic polymers using a melt-layer process. We characterized them by differential scanning calorimetry, fluorescence spectroscopy and functional assays (DNA capture assay, model for cell adhesion, bacterial adhesion and biofilm formation test). Results: From 14 tested colored, transparent and black materials we found only deep black acrylonitrile-butadiene-styrene (ABS) and some black polylactic acid (PLA) useable for fluorescence-based assays, with low autofluorescence only in the short-wave range of 300-400 nm. PLA was suitable for standard bioanalytical purposes due to a glass transition temperature of approximately 60°C, resistance to common laboratory chemicals and easy print processing. For temperature-critical methods, such as hybridization reactions up to 90°C, ABS was better suited. Conclusions: Autofluorescence was not a disadvantage per se but can also be used as a reference signal in assays. The rapid development of individual protocols for sample processing and analysis required the availability of a material with consistent quality over time. For fluorescence-based assays, the use of commercial standard materials did not seem to meet this requirement.}, language = {en} } @misc{LopensKrawczykPappetal., author = {Lopens, Steffi and Krawczyk,

In Cameroon, these activities cause a loss of suitable primate habitat and could ultimately threaten the survival of chimpanzees (Pan troglodytes). We derived independent estimates of the population size of the Endangered Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) in Kom-Wum Forest Reserve, Cameroon, and surrounding unprotected forest areas through 1) direct observations, 2) camera trapping, 3) distance sampling, 4) marked nest counts, and 5) standing crop nest counts. In addition, we georeferenced signs of chimpanzee and human activity along line transects. We used a generalized linear mixed model to predict the occurrence of chimpanzees in response to edge length (measured as the perimeter of core forest patches), core area of forest patches (measured as area of forest patches beyond an edge width of 100 m), habitat perforation (measured as the perimeter of nonforested landscape within core forest patches), patch size(measured as area of forest patches), and forest cover. Chimpanzee density estimates ranged from 0.1 (direct observation) to 0.9 (distance sampling) individuals km-2 depending on estimation method with a mean nest group size of 7 ± 5.4 (SD). The mean encounter rate for signs of chimpanzee activity was significantly higher in mature forests (2.3 signs km-1) than in secondary forests (0.3 signs km-1) and above 1000 m elevation (4.0 signs km-1) than below 1000 m (1.0 signs km-1). The mean encounter rate for signs of human activity was significantly higher in secondary (8.0 signs km-1) than in mature forests (0.9 signs km-1). Secondary forests, habitat perforation, and edge length had a significant negative effect on the occurrence of chimpanzee signs. Overall, human activity and forest degradation affected the number of observed chimpanzee signs negatively. Regular antipoaching patrols and reforestation programs in degraded areas could potentially reduce threats to populations of endangered species and may increase suitable habitat area.}, language = {en} } @misc{SchmidtBorcherdingThieleetal., author = {Schmidt, Carsten and Borcherding, Heike and Thiele, Thomas and Schedler, Uwe and Werner, Franziska and R{\"o}diger, Stefan and Roggenbuck, Dirk and Schierack, Peter}, title = {Fluorescence-encoded poly (methyl metharcylate) nanoparticles for a lateral flow assay detecting IgM autoantibodies in rheumatoid arthritis}, series = {Analytical biochemistry}, volume = {Vol. 633}, journal = {Analytical biochemistry}, issn = {1096-0309}, doi = {10.1016/journal.ppat.1010118}, language = {en} } @misc{EmmeneggerKumarEmmeneggeretal., author = {Emmenegger, Marc and Kumar, Sreedhar Saseendran and Emmenegger, Vishalini and Malinauskas, Tomas and B{\"u}ttner, Thomas and Rose, Laura and Schierack, Peter and Sprinzl, Martin F. and Sommer, Clemens J. and Lackner, Karl J. and Aguzzi, Adriano and Roggenbuck, Dirk and Frauenknecht, Katrin B.

In addition to opportunistic representatives, hypervirulent (hvKp) and antibiotic-resistant K. pneumoniae (ABR-Kp) occur. While ABR-Kp isolates often cause difficult-to-treat diseases due to limited therapeutic options, hvKp is a pathotype that can infect healthy individuals often leading to recurrent infection. Here, we investigated the clinical K. pneumoniae isolate PBIO3459 obtained from a blood sample, which showed an unusual colony morphology. By combining whole-genome and RNA sequencing with multiple in vitro and in vivo virulence-associated assays, we aimed to define the respective Klebsiella subtype and explore the unusual phenotypic appearance. We demonstrate that PBIO3459 belongs to sequence type (ST)20 and carries no acquired resistance genes, consistent with phenotypic susceptibility tests. In addition, the isolate showed low-level virulence, both at genetic and phenotypic levels. We thus suggest that PBIO3459 is an opportunistic (commensal) K. pneumoniae isolate. Genomic comparison of PBIO3459 with closely related ABR-Kp ST20 isolates revealed that they differed only in resistance genes. Finally, the unusual colony morphology was mainly associated with carbohydrate and amino acid transport and metabolism. In conclusion, our study reveals the characteristics of a Klebsiella sepsis isolate and suggests that opportunistic representatives likely acquire and accumulate antibiotic resistances that subsequently enable their emergence as ABR-Kp pathogens.}, language = {en} } @misc{KhanSidorczukBeckeretal., author = {Khan, Muhammad Moman and Sidorczuk, Katarzyna and Becker, Juliane and Aleksandrowicz, Adrianna and Baraniewicz, Karolina and Ludwig, Christina and Ali, Aamir and Kingsley, Robert A. and Schierack, Peter and Kolenda, Rafał}, title = {Characterization of clumpy adhesion of Escherichia coli to human cells and associated factors influencing antibiotic sensitivity}, series = {Microbiology Spectrum}, journal = {Microbiology Spectrum}, issn = {2165-0497}, doi = {10.1128/spectrum.02606-23}, abstract = {Escherichia coli intestinal infection pathotypes are characterized by distinct adhesion patterns, including the recently described clumpy adhesion phenotype. Here, we identify and characterize the genetic factors contributing to the clumpy adhesion of E. coli strain 4972. In this strain, the transcriptome and proteome of adhered bacteria were found to be distinct from planktonic bacteria in the supernatant. A total of 622 genes in the transcriptome were differentially expressed in bacteria present in clumps relative to the planktonic bacteria. Seven genes targeted for disruption had variable distribution in different pathotypes and nonpathogenic E. coli, with the pilV and spnT genes being the least frequent or absent from most groups. Deletion (Δ) of five differentially expressed genes, flgH, ffp, pilV, spnT, and yggT, affected motility, adhesion, or antibiotic stress. ΔflgH exhibited 80\% decrease and ΔyggT depicted 184\% increase in adhesion, and upon complementation, adhesion was significantly reduced to 13\%. ΔflgH lost motility and was regenerated when complemented, whereas Δffp had significantly increased motility, and reintroduction of the same gene reduced it to the wild-type level. The clumps produced by Δffp and ΔspnT were more resistant and protected the bacteria, with ΔspnT showing the best clump formation in terms of ampicillin stress protection. ΔyggT had the lowest tolerance to gentamicin, where the antibiotic stress completely eliminated the bacteria.

Upon examination of affected tissue, pathological changes reveal a loss of synapses, misfolded proteins, and activation of immune cells—all indicative of disease progression—before severe clinical symptoms become apparent. Early detection of NDs is crucial for potentially administering targeted medications that may delay disease advancement. Given their complex pathophysiological features and diverse clinical symptoms, there is a pressing need for sensitive and effective diagnostic methods for NDs. Biomarkers such as microRNAs (miRNAs) have been identified as potential tools for detecting these diseases. We explore the pivotal role of miRNAs in the context of NDs, focusing on Alzheimer's disease, Parkinson's disease, Multiple sclerosis, Huntington's disease, and Amyotrophic Lateral Sclerosis. The review delves into the intricate relationship between aging and NDs, highlighting structural and functional alterations in the aging brain and their implications for disease development. It elucidates how miRNAs and RNA-binding proteins are implicated in the pathogenesis of NDs and underscores the importance of investigating their expression and function in aging. Significantly, miRNAs exert substantial influence on post-translational modifications (PTMs), impacting not just the nervous system but a wide array of tissues and cell types as well. Specific miRNAs have been found to target proteins involved in ubiquitination or de-ubiquitination processes, which play a significant role in regulating protein function and stability. We discuss the link between miRNA, PTM, and NDs. Additionally, the review discusses the significance of miRNAs as biomarkers for early disease detection, offering insights into diagnostic strategies.}, language = {en} } @misc{FrostWeissHerteletal., author = {Frost, Fabian and Weiss, Stefan and Hertel, Johannes and R{\"u}hlemann, Malte and Bang, Corinna and Franke, Andre and Nauck, Matthias and D{\"o}rr, Marcus and V{\"o}lzke, Henry and Roggenbuck, Dirk and Schierack, Peter and V{\"o}lker, Uwe and Homuth, Georg and Aghdassi, Ali A. and Sendler, Matthias and Lerch, Markus M. and Weiss, Frank U.}, title = {Fecal glycoprotein 2 is a marker of gut microbiota dysbiosis and systemic inflammation}, series = {Gut Pathogens}, volume = {16}, journal = {Gut Pathogens}, number = {1}, publisher = {Springer Science and Business Media LLC}, issn = {1757-4749}, doi = {10.1186/s13099-024-00657-1}, pages = {1 -- 11}, abstract = {Background autoantigenic glycoprotein 2 (GP2) is an important component of the innate immune system which originates from the exocrine pancreas as well as from the small intestines. The relationship of GP2 with the intestinal microbiome as well as the systemic implications of increased fecal GP2 levels are, however, still unclear. Therefore, fecal samples from 2,812 individuals of the Study of Health in Pomerania (SHIP) were collected to determine GP2 levels (enzyme-linked immunosorbent assay) and gut microbiota profiles (16 S rRNA gene sequencing). These data were correlated and associated with highly standardised and comprehensive phenotypic data of the study participants. Results Fecal GP2 levels were increased in individuals with higher body mass index and smokers, whereas lower levels were found in case of preserved exocrine pancreatic function, female sex or a healthier diet. Moreover, higher GP2 levels were associated with increased serum levels of high-sensitivity C-reactive protein, loss of gut microbial diversity and an increase of potentially detrimental bacteria (Streptococcus, Haemophilus, Clostridium XIVa, or Collinsella). At the same time, predicted microbial pathways for the biosynthesis of beneficial short-chain fatty acids or lactic acid were depleted in individuals with high fecal GP2. Of note, GP2 exhibited a stronger association to overall microbiome variation than calprotectin. Conclusion Fecal GP2 is a biomarker of gut microbiota dysbiosis and associated with increased systemic inflammation. The intestines may be more important as origin for GP2 than pancreatic acinar cells.

Non-clinical reservoirs of AMR, such as agriculture and food production facilities, may contribute to the transmission of clinically relevant pathogens such as multidrug-resistant (MDR) Klebsiella pneumoniae. There is currently very limited knowledge regarding the population structure and genomic diversity of K. pneumoniae in poultry production in Pakistan.MethodsWe explored healthy broilers in a commercial farm from Faisalabad, Pakistan, and identified six K. pneumoniae strains from 100 broiler birds. We characterized the strains, determining clonality, virulence and antimicrobial resistance genes using next generation sequencing.ResultsThe evaluation of antimicrobial susceptibility revealed that all the strains were MDR. Genomic analysis showed that 3/6 strains belonged to ST152, harbouring acquired resistance aminoglycosides [aadA2, aph(4′)-Ia], β-lactams (blaSHV-187, blaLAP2), fosfomycin (fosA6), tetracycline (tetA), trimethoprim (dfrA12), quinolone (qnrS1), sulphonamides (sul2) and phenicol (floR). All the strains harboured the efflux pump genes oqxA, oqxB, emrR, kpnG, kpnH, kpnF, baeR, mtdB and mtdC. All six strains encoded identical virulence profiles possessing six genes, i.e., ureA, iutA, entB, allS, fimH and mrkD. Phylogenomic analysis of the dominant sequence type (ST152) present in our dataset with publicly available genomes showed that the isolates clustered to strains mainly from human sources and could pose a potential threat to food safety and public health.DiscussionThe combination of these findings with antimicrobial use data would allow a better understanding of the selective pressures that may be driving the spread of AMR. This is the first report of MDR K. pneumoniae isolated from broiler hens in Pakistan, and the finding suggests that routine surveillance of WHO critical priority pathogens in such settings would be beneficial to the development of effective control strategies to reduce AMR.}, language = {en} } @misc{FotangDuttonBroeringetal., author = {Fotang, Chefor and Dutton, Paul and Br{\"o}ring, Udo and Roos, Christian and Willie, Jacob and Angwafo, Tsi Evaristus and Chuo, Mvo Denis and Kamgang, Serge Alexis and Enoguanbhor, Evidence Chinedu and Schierack, Peter and Birkhofer, Klaus}, title = {Tool use by Nigeria-Cameroon chimpanzees for driver ant predation in Kom-Wum Forest Reserve, North-West Region Cameroon}, series = {Folia Primatologica}, volume = {94}, journal = {Folia Primatologica}, number = {1}, issn = {1421-9980}, doi = {10.1163/14219980-bja10006}, pages = {73 -- 85}, abstract = {Chimpanzees feed on driver ants (Dorylus sp.) using different tools and predation techniques that vary among populations and can be affected by availability of ant species as well as ecological and social-learning factors.

We recovered 83 tools along line transects and recces (reconnaissance) during two seasons. We found that chimpanzees used tools with blunting and dirty ends (possible digging and probing tools) and tools without (dipping tools), in driver ant predation. Tools with dirty ends tended to be thicker (N = 52), and thinner tools were less likely to have dirt (N = 31). Tools recovered in the wet season (N = 62), were significantly shorter and thicker than those recovered in the dry season (N = 21). Furthermore, driver ant tools recovered at KWFR are on average the longest yet recorded insect dipping tools for chimpanzees comparable to those used in North Uele. We found no evidence of nut-cracking, tool use for honey bee nor termite consumption and did not observe the potential prey remains in chimpanzee faeces despite their presence in the reserve.

Little is known about habitat suitability of the Nigeria-Cameroon chimpanzee [Pan troglodytes ellioti (Matschie, 1914)], particularly for populations inhabiting forest reserves in North-West Cameroon. To address this knowledge gap, we employed a common species distribution model (MaxEnt) to map and predict suitable habitats for the Nigeria-Cameroon chimpanzee in Kom-Wum Forest Reserve, North-West Cameroon, based on environmental factors that potentially affect habitat suitability. We related these environmental factors to a dataset of chimpanzee occurrence points recorded during line transect and reconnaissance (recce) surveys in the forest reserve and surrounding forests. Up to 91\% of the study area is unsuitable for chimpanzees. Suitable habitats only represented 9\% of the study area, with a high proportion of highly suitable habitats located outside the forest reserve. Elevation, secondary forests density, distance to villages and primary forests density were the most important predictors of habitat suitability for the Nigeria-Cameroon chimpanzee. The probability of chimpanzee occurrence increased with elevation, secondary forest density and distance from villages and roads.

Thus, autoAb testing could aid in the diagnosis of BPH patients profiting from such therapy. We generated CRISPR/Cas9 modified HEp-2 LEDGF knock-out (KO) and HEp-2 LEDGF/p75 over-expressing (OE) cells and examined IgG autoantibody reactivity to LEDGF/p75 in patients with prostate cancer (PCa, n = 89), bladder cancer (BCa, n = 116), benign prostatic hyperplasia (BPH, n = 103), and blood donors (BD, n = 60) by indirect immunofluorescence assay (IFA). Surprisingly, we could not detect elevated binding of autoAbs against LEDGF/p75 in cancer patients, but autoAb reactivity to LEDGF/p75 OE cells in about 50\% of patients with BPH was unexpectedly significantly increased. Furthermore, a line immunoassay enabling the detection of 18 different autoAbs revealed a significantly increased occurrence of anti-dsDNA autoAbs in 34\% of BPH patients in contrast to tumor patients and BD. This finding was confirmed by anti-mitochondrial (mDNA) autoAb detection with the Crithidia luciliae immunofluorescence test, which also showed a significantly higher prevalence (34\%) of anti-mDNA autoAbs in BPH.

We also tested the ability of CytoBead ANA DFS-70 to identify dense-fine speckled (DFS) pattern associated with anti-DFS70 antibodies in non-SARDs patients. Hundred-twelve routine sera samples were assessed by manual CytoBead ANA 2 for the presence of ANA and specific autoantibodies. In parallel, these samples were analyzed by HEp2 ANA IIF test and a subsequent multiplexed assay BioPlex™ 2200 ANA. Twenty-nine ANA-positive samples obtained from non-SARDs patients and exhibiting DFS pattern by ANA IIF were further tested by CytoBead ANA DFS-70. A substantial agreement was observed between classical ANA IIF and manual CytoBead ANA 2 for the detection of ANA (k = 0.74). Discordant results were mainly associated with the presence of anti-SSA/Ro antibodies detected by CytoBead ANA 2 in ANA IIF negative patients. A good to almost perfect agreement was found between CytoBead ANA 2 and BioPlex™ 2200 for detection of specific antibodies with kappa values ranging from 0.70 to 0.90.

This review summarizes for researchers on the role of miRNAs in NDDs by examining their diagnostic potential in biofluids such as blood and cerebrospinal fluid, and their therapeutic applicability through inhibition or replacement strategies. Literature from peer-reviewed databases was assessed with a focus on recent advances in molecular detection platforms, computational modeling of miRNA-mRNA interactions, and preclinical/clinical investigations. More than 2600 human miRNAs have been identified, collectively regulating over half of mammalian protein-coding genes. Quantitative methodologies, particularly reverse transcription quantitative PCR (RT-qPCR), enable reliable miRNA profiling, facilitating early diagnosis and prognosis of NDDs. Therapeutic strategies, including antagomirs, mimics, sponges and viral or non-viral delivery systems, show promise in modulating disease pathways. However, significant challenges remain, including variability in miRNA extraction and quantification protocols, off-target effects, delivery barriers across the blood brain barrier and limited reproducibility across studies. MiRNAs represent a class of molecular tools with potential to transform diagnostics and therapeutics in NDDs. Future research should prioritize methodological standardization, validation in large multicenter cohorts, and improved computational approaches to elucidate miRNA-mediated regulatory networks in NDDs.
