    Abstract G protein-coupled receptors (GPCR) are involved in various physiological and pathophysiological processes. Functional autoantibodies targeting GPCRs have been associated with multiple disease manifestations in this context. Here we summarize and discuss the relevant findings and concepts presented in the biennial International Meeting on autoantibodies targeting GPCRs (the 4th Symposium), held in Lübeck, Germany, 15-16 September 2022. The symposium focused on the current knowledge of these autoantibodies' role in various diseases, such as cardiovascular, renal, infectious (COVID-19), and autoimmune diseases (e.g., systemic sclerosis and systemic lupus erythematosus). Beyond their association with disease phenotypes, intense research related to the mechanistic action of these autoantibodies on immune regulation and pathogenesis has been developed, underscoring the role of autoantibodies targeting GPCRs on disease outcomes and etiopathogenesis. The observation repeatedly highlighted that autoantibodies targeting GPCRs could also be present in healthy individuals, suggesting that anti-GPCR autoantibodies play a physiologic role in modeling the course of diseases. Since numerous therapies targeting GPCRs have been developed, including small molecules and monoclonal antibodies designed for treating cancer, infections, metabolic disorders, or inflammatory conditions, anti-GPCR autoantibodies themselves can serve as therapeutic targets to reduce patients' morbidity and mortality, representing a new area for the development of novel therapeutic interventions.

    Abstract Primary skin fibroblasts from two Parkinson's disease (PD) patients carrying distinct heterozygous mutations in the RHOT1 gene encoding Miro1, namely c.1290A > G (Miro1 p.T351A) and c.2067A > G (Miro1 p.T610A), were converted into induced pluripotent stem cells (iPSCs) by episomal reprogramming. The corresponding isogenic gene-corrected lines have been generated using CRISPR/Cas9 technology. Here, we provide a comprehensive characterization and quality assurance of both isogenic pairs, which will be used to study Miro1-related molecular mechanisms underlying neurodegeneration in iPSC-derived neuronal models (e.g., midbrain dopaminergic neurons and astrocytes).

    Abstract Introduction: Graft-versus-host disease (GvHD) is a major complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and is highly influenced by the degree of HLA matching between recipient and donor. The HLA-class Ib molecule HLA-G has been shown to promote tolerogenicity through its interaction with inhibitory receptors found on several immunocompetent cells. We hypothesized that in an allo-HSCT setting, HLA-G mismatches may negatively impact the HLA-G-mediated tolerogenicity either due to inefficient interaction with the inhibitory receptors of the transplanted immune cells or due to direct allorecognition of mismatched HLA-G on host cells by the immune cells of the donor.
    Methods: In order to explore this hypothesis, we investigated the impact of HLA-G mismatching in 2.083 10/10 matched high resolution HLA-typed allo-HSCT transplants.
    Results: We found that the risk of chronic GvHD was significantly higher in HLA-G-mismatched transplant cases as compared with the HLA-G-matched control group (HR: 1.46, 95%CI = 1.11-1.91, p = 0.006). Sub-analysis of the mismatch vector revealed that this effect was only detectable in the GvH (HR: 1.89, 95%CI 1.39-2.57, p < 0.001) but not the HvG direction (HR: 1.01, 95%CI = 0.63-1.63, p = 0.967). In addition, the negative impact of HLA-G mismatching on chronic GvHD was only significant in younger patients (<30y HR: 3.02, 95%CI = 1.25-7.28, p = 0.014; >29y HR: 1.28, 95%CI = 0.94-1.72, p = 0.113).
    Discussion: Our results indicate that HLA-G mismatches may contribute to the onset of chronic GvHD, especially in younger patients and should therefore be avoided when possible.

    Abstract Metagenomics has demonstrated its capability in outbreak investigations and pathogen surveillance and discovery. With high-throughput and effective bioinformatics, many disease-causing agents, as well as novel viruses of humans and animals, have been identified using metagenomic analysis. In this study, a VIDISCA metagenomics workflow was used to identify potential unknown viruses in 33 fecal samples from asymptomatic long-tailed macaques (

    Title translation Die deutsche Version der Mind Excessively Wandering Scale (MWES-G): eine Validierungsstudie.
    Abstract Increasing evidence shows that unintentional mind wandering is linked to Attention Deficit Hyperactivity Disorder (ADHD) and that its frequency contributes to symptom severity and functional impairment in ADHD. However, empirical data on mind wandering in adult ADHD are still scarce, and a validated scale to assess mind wandering in German adult ADHD patients is lacking. The primary aim of this study is to assess the psychometric properties of the German version of the recently published Mind Excessively Wandering Scale (MEWS-G) in terms of factorial structure and factor stability, internal consistency and construct validity. Analyses were performed in 128 adults with ADHD, clinical and healthy controls. As described for the original English 15-item version of the scale, we found lowest item-total-correlations for items 6, 10 and 14 with item-total correlation of all: 0.54/ADHD: 0.32 (item 6), all: 0.55/ADHD: 0.39 (item 10) and all: 0.11/ADHD: -0.04 (item 14). Item-total correlations for the remaining items were 0.65-0.86 and Cronbach Alpha was 0.96 indicating good internal consistency of the 12-item version of scale, on which we based all further analyses. Principal component analysis indicated a one- and two- factorial scale structure respectively explaining 71.7 % and 78.7 % of variance. Both factors showed good stability with lower stability of the factor-2 solution if sample size was reduced. The two-factorial solution also had many cross-loadings and a strong correlation of both factors in confirmatory factorial analysis (rf1f2 = 0.87). It probably describes related and interdependent, but not distinct facets of mind wandering, which strongly argues for the one factorial structure of the scale. Mean MEWS-G score in ADHD was 23.77 ± 7.85 compared to 7.64 ± 7.27 in controls (p < .0001). According to ROC, the optimal cut-off point to discriminate ADHD and controls is at MEWS-G score = 13. On the symptom level, MEWS-G score was correlated with ADHD, depressive and total psychiatric symptom scores, on the personality level with neuroticsm and negatively with conscientiousness and on the functional level with social interaction difficulties and impaired self-efficacy. In summary, our study shows that MEWS-G is a reliable, valid instrument to assess spontaneous mind wandering in adult ADHD and to discriminate between ADHD and controls.

    Abstract Objectives: To compare survival and short-term respiratory outcomes of infants weighing <750 g initially intubated with 2.0 mm versus 2.5 mm endotracheal tube (ETT).
    Study design: Retrospective, observational cohort study.
    Results: Of 149 inborn infants weighing <750 g admitted to the NICU, 69 (46%) were intubated with 2.0 mm ETT, 78 with 2.5 mm ETT (53%), and 2 infants never required intubation. Infants intubated with 2.0 mm ETT were more premature (median gestational age (GA) 23 weeks (22, 24) vs. 24 weeks (24, 25) p < 0.0001), smaller (median birth weight 545 g (450, 616) vs. 648 g (579, 700), p < 0.0001), and more frequently intubated at delivery (96% vs. 68%, p < 0.00001). Survival to discharge was similar 77%, 53/69 and 87%, 68/78 (p = 0.09). Adjusted for GA, there were no significant differences in ventilator days (p = 0.7338) or Grade 3 BPD.
    Conclusions: Premature infants born at a median GA of 23 weeks and median birth weight of 545 g can be successfully managed with 2.0 mm ETT.

    Abstract Adoptive natural killer (NK) cell therapy is attaining promising clinical outcomes in recent years, but improvements are needed. Genetic modification of NK cells with a tumor antigen-specific receptor on their surface coupled to intracellular signaling domains may lead to enhanced cytotoxicity against malignant cells. One of the most common approaches is by lentivirus-mediated transduction. However, NK cells are difficult to transduce and various methods have been attempted with different success rates. Because the low-density lipoprotein-receptor (LDLR) is the receptor of vesicular stomatitis virus (VSV) and is expressed only at low levels on NK cells, we tested the potential of 5 statins and 5 non-statin compounds to increase the LDLR expression, thereby facilitating viral transduction. We found that the transduction efficiency of VSV-G pseudotyped lentivirus is augmented by statins that induced higher LDLR expression. In both NK-92 cells and primary NK cells, the transduction efficiency increased after treatment with statins. Furthermore, statins have been reported to suppress NK cell cytotoxicity; however, we showed that this can be completely reversed by adding geranylgeranyl-pyrophosphate (GGPP). Among the statins tested, we found that the combination of rosuvastatin with GGPP most potently improved viral transduction without affecting the cytotoxic properties of the NK cells.
