Early diagnosis of aGVHD remains difficult and is based on clinical symptoms and histopathological evaluation of tissue biopsies. Thus, current aGVHD diagnosis is limited to patients with established disease manifestation. Therefore, for improved disease prevention it is important to develop predictive assays to identify patients at risk of developing aGVHD. Here we address whether insights into the timing of the aGVHD initiation and effector phases could allow for the detection of migrating alloreactive T cells before clinical aGVHD onset to permit for efficient therapeutic intervention. Methods Murine major histocompatibility complex (MHC) mismatched and minor histocompatibility antigen (miHAg) mismatched allo-HCT models were employed to assess the spatiotemporal distribution of donor T cells with flow cytometry and in vivo bioluminescence imaging (BLI). Daily flow cytometry analysis of peripheral blood mononuclear cells allowed us to identify migrating alloreactive T cells based on homing receptor expression profiles. Results We identified a time period of 2 weeks of massive alloreactive donor T cell migration in the blood after miHAg mismatch allo-HCT before clinical aGVHD symptoms appeared. Alloreactive T cells upregulated α4β7 integrin and P-selectin ligand during this migration phase. Consequently, targeted preemptive treatment with rapamycin, starting at the earliest detection time of alloreactive donor T cells in the peripheral blood, prevented lethal aGVHD. Conclusions Based on this data we propose a critical time frame prior to the onset of aGVHD symptoms to identify alloreactive T cells in the peripheral blood for timely and effective therapeutic intervention.}, language = {en} } @article{OttoFriedrichMadunićetal.2020, author = {Otto, Christoph and Friedrich, Alexandra and Madunić, Ivana Vrhovac and Baumeier, Christian and Schwenk, Robert W. and Karaica, Dean and Germer, Christoph-Thomas and Sch{\"u}rmann, Annette and Sabolić, Ivan and Koepsell, Hermann, Hermann}, title = {Antidiabetic Effects of a Tripeptide That Decreases Abundance of Na\(^+\)-D-glucose Cotransporter SGLT1 in the Brush-Border Membrane of the Small Intestine}, series = {ACS Omega}, volume = {5}, journal = {ACS Omega}, number = {45}, doi = {10.1021/acsomega.0c03844}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-230654}, pages = {29127-29139}, year = {2020}, abstract = {In enterocytes, protein RS1 (RSC1A1) mediates an increase of glucose absorption after ingestion of glucose-rich food via upregulation of Na+-D-glucose cotransporter SGLT1 in the brush-border membrane (BBM). Whereas RS1 decelerates the exocytotic pathway of vesicles containing SGLT1 at low glucose levels between meals, RS1-mediated deceleration is relieved after ingestion of glucose-rich food. Regulation of SGLT1 is mediated by RS1 domain RS1-Reg, in which Gln-Ser-Pro (QSP) is effective. In contrast to QSP and RS1-Reg, Gln-Glu-Pro (QEP) and RS1-Reg with a serine to glutamate exchange in the QSP motif downregulate the abundance of SGLT1 in the BBM at high intracellular glucose concentrations by about 50\%. We investigated whether oral application of QEP improves diabetes in db/db mice and affects the induction of diabetes in New Zealand obese (NZO) mice under glucolipotoxic conditions. After 6-day administration of drinking water containing 5 mM QEP to db/db mice, fasting glucose was decreased, increase of blood glucose in the oral glucose tolerance test was blunted, and insulin sensitivity was increased. When QEP was added for several days to a high fat/high carbohydrate diet that induced diabetes in NZO mice, the increase of random plasma glucose was prevented, accompanied by lower plasma insulin levels. QEP is considered a lead compound for development of new antidiabetic drugs with more rapid cellular uptake. In contrast to SGLT1 inhibitors, QEP-based drugs may be applied in combination with insulin for the treatment of type 1 and type 2 diabetes, decreasing the required insulin amount, and thereby may reduce the risk of hypoglycemia.}, language = {en} } @article{FerreiraGamazonAlEjehetal.2019, author = {Ferreira, Manuel A. and Gamazon, Eric R. and Al-Ejeh, Fares and Aittom{\"a}ki, Kristiina and Andrulis, Irene L. and Anton-Culver, Hoda and Arason, Adalgeir and Arndt, Volker and Aronson, Kristan J. and Arun, Banu K. and Asseryanis, Ella and Azzollini, Jacopo and Balma{\~n}a, Judith and Barnes, Daniel R. and Barrowdale, Daniel and Beckmann, Matthias W. and Behrens, Sabine and Benitez, Javier and Bermisheva, Marina and Bialkowska, Katarzyna and Blomqvist, Carl and Bogdanova, Natalia V. and Bojesen, Stig E. and Bolla, Manjeet K. and Borg, Ake and Brauch, Hiltrud and Brenner, Hermann and Broeks, Annegien and Burwinkel, Barbara and Cald{\´e}s, Trinidad and Caligo, Maria A. and Campa, Daniele and Campbell, Ian and Canzian, Federico and Carter, Jonathan and Carter, Brian D. and Castelao, Jose E. and Chang-Claude, Jenny and Chanock, Stephen J. and Christiansen, Hans and Chung, Wendy K. and Claes, Kathleen B.

Here we hypothesize that some risk-associated variants might act in non-breast tissues, specifically adipose tissue and immune cells from blood and spleen. Using expression quantitative trait loci (eQTL) reported in these tissues, we identify 26 previously unreported, likely target genes of overall breast cancer risk variants, and 17 for estrogen receptor (ER)-negative breast cancer, several with a known immune function. We determine the directional effect of gene expression on disease risk measured based on single and multiple eQTL. In addition, using a gene-based test of association that considers eQTL from multiple tissues, we identify seven (and four) regions with variants associated with overall (and ER-negative) breast cancer risk, which were not reported in previous GWAS.

Metabolite repair enzymes may represent an alternative target class for selective metabolic inhibition, but pharmacological tools to test this concept are needed. Here, we demonstrate that phosphoglycolate phosphatase (PGP), a prototypical metabolite repair enzyme in glycolysis, is a pharmacologically actionable target. Using a combination of small molecule screening, protein crystallography, molecular dynamics simulations and NMR metabolomics, we discover and analyze a compound (CP1) that inhibits PGP with high selectivity and submicromolar potency. CP1 locks the phosphatase in a catalytically inactive conformation, dampens glycolytic flux, and phenocopies effects of cellular PGP-deficiency. This study provides key insights into effective and precise PGP targeting, at the same time validating an allosteric approach to control glycolysis that could advance discoveries of innovative therapeutic candidates.}, language = {en} } @phdthesis{Hermann2004, author = {Hermann, Robert}, title = {Klinische und radiologische Ergbebnisse der MRP-Revisionsprothese bei verschiedenen Knochendefekten des Femur}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-13451}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2004}, abstract = {Im Zeitraum zwischen Januar 1998 bis M{\"a}rz 2000 wurden 51 Patienten, die mit einer MRP- H{\"u}ft-Revisionsprothese versorgt worden sind klinisch und radiologisch nachuntersucht.

Because mortality can reach 100\%, PDS is a serious threat for affected fish populations. Recently, Kuehn and colleagues reported that a high throughput RNA sequencing approach identified a piscine orthoreovirus (PRV) as a causative agent of PDS. We investigated samples from PDS-affected fish obtained from two exposure experiments performed at the river Iller in 2008 and 2009. Using a RT-qPCR and a well-established next-generation RNA sequencing pipeline for pathogen detection, PRV-specific RNA was not detectable in PDS fish from 2009. In contrast, PRV RNA was readily detectable in several organs from diseased fish in 2008. However, similar virus loads were detectable in the control fish which were not exposed to Iller water and did not show any signs of the disease. Therefore, we conclude that PRV is not the causative agent of PDS of brown trout in the rhithral region of alpine Bavarian limestone rivers. The abovementioned study by Kuehn used only samples from the exposure experiment from 2008 and detected a subclinical PRV bystander infection. Work is ongoing to identify the causative agent of PDS.}, language = {en} } @article{EinseleBorghaeiOrlowskietal.2020, author = {Einsele, Hermann and Borghaei, Hossein and Orlowski, Robert Z. and Subklewe, Marion and Roboz, Gail J. and Zugmaier, Gerhard and Kufer, Peter and Iskander, Karim and Kantarjian, Hagop M.}, title = {The BiTE (Bispecific T-Cell Engager) Platform: Development and Future Potential of a Targeted Immuno-Oncology Therapy Across Tumor Types}, series = {Cancer}, volume = {126}, journal = {Cancer}, number = {14}, doi = {10.1002/cncr.32909}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-215426}, pages = {3192 -- 3201}, year = {2020}, abstract = {Immuno-oncology therapies engage the immune system to treat cancer.
