Antibody-mediated rejection (AMR) is among the most frequent causes for graft loss after kidney transplantation. While there are no approved therapies, several case reports with daratumumab and the very recent phase 2 trial of felzartamab in AMR have indicated the potential efficacy of therapeutic interventions targeting CD38. Donor-derived cell-free DNA (dd-cfDNA) is an emerging biomarker with injury-specific release and a short half-life, which could facilitate early diagnosis of AMR and monitoring of treatment response.

Co-observation of germline pathogenic variants in breast cancer predisposition genes: Results from analysis of the BRIDGES sequencing dataset.

Am J Hum Genet

September 2024

Population Health Program, QIMR Berghofer Medical Research Institute, Brisbane, QLD 4006, Australia; Faculty of Medicine, The University of Queensland, Brisbane, QLD 4072, Australia. Electronic address:

Article Synopsis
  • * Analysis of data from over 55,000 breast cancer patients showed that co-observation of variants in BRCA1, BRCA2, and PALB2 with other breast cancer genes occurred less frequently than expected, suggesting a potential correlation with pathogenicity.
  • * The findings indicate that identifying a variant of uncertain significance alongside a known pathogenic variant supports evidence against the variant's pathogenicity, which could improve variant classification in clinical settings and for other genetic conditions.

Bottom Contact Engineering for Ambient Fabrication of >25% Durable Perovskite Solar Cells.

Adv Mater

October 2024

School of Environment and Energy, State Key Laboratory of Luminescent Materials and Devices, Guangdong Provincial Key Laboratory of Solid Wastes Pollution Control and Recycling, South China University of Technology, Guangzhou, 510000, China.

The bottom contact in perovskite solar cells (PSCs) is easy to cause deep trap states and severe instability issues, especially under maximum power point tracking (MPPT). In this study, sodium gluconate (SG) is employed to disperse tin oxide (SnO) nanoparticles (NPs) and regulate the interface contact at the buried interface. The SG-SnO electron transfer layer (ETL) enabled the deposition of pinhole-free perovskite films in ambient air and improved interface contact by bridging effect.

Reforestation and afforestation either through natural regeneration, tree planting or both methods have been globally promoted to motivate ecological restoration of degraded lands and to improve livelihoods. However, moisture stress and infertile soils limit the survival and growth of trees planted for restoration in drier areas. Hence, understanding the factors that determine the restoration success of drylands through tree planting is critical.

Exhausted Lag-3+ CD4+ T cells are increased in pediatric Inflammatory Bowel Disease.

Clin Exp Immunol

July 2024

Pediatric Gastroenterology, Hepatology and Endoscopy, Department of Pediatrics and Adolescent Medicine, University Hospital Erlangen, Friedrich-Alexander-University Erlangen-Nuremberg.

Article Synopsis
  • T cells play a crucial role in inflammatory bowel diseases (IBD), and infliximab (IFX) is used to treat IBD by neutralizing TNFα to induce remission.
  • A study assessed the immune profiles of pediatric IBD patients before and during IFX therapy, focusing on T cell characteristics to identify potential predictors for treatment success.
  • Findings indicated that non-responders to IFX showed increased levels of the checkpoint molecule Lag-3 on their T cells, suggesting a more exhausted phenotype compared to responders, which could serve as a biomarker for therapy failure.

Article Synopsis
  • Researchers use laser spectroscopy at very low temperatures (2 K) to study single dibenzoterrylene (DBT) molecules in tiny anthracene crystals made through a special printing technique.
  • They find that the light emitted by these single molecules has very sharp transitions, almost as clear as those seen in bulk materials, indicating high-quality optical properties.
  • By taking super-resolution images and changing the polarization of the light, they can measure the size and orientation of the crystals, which is important for future applications involving precisely placed quantum emitters.

J Clin Med

July 2024

Machine Learning and Data Analytics Laboratory, Department Artificial Intelligence in Biomedical Engineering, Friedrich Alexander University Erlangen-Nuremberg, 91052 Erlangen, Germany.

Article Synopsis
  • bDMARDs are effective for treating Rheumatoid Arthritis (RA), but about 30% of patients don't respond, highlighting the need to predict treatment outcomes.
  • The study used machine learning on clinical data from 154 RA patients to forecast initial and sustained responses to treatment after 6 and 12 months, comparing several models including XGBoost and AdaBoost.
  • XGBoost showed the highest accuracy for initial response prediction, while AdaBoost excelled in forecasting sustained response; higher Disease Activity Scores indicated poorer chances of responding to treatment.

MRC Epidemiology Unit, University of Cambridge School of Clinical Medicine, Institute of Metabolic Science, Cambridge Biomedical Campus, Cambridge, UK.

Article Synopsis
  • Scientists looked at the timing of when girls start their periods (called menarche) and how it can affect their health later in life.
  • They studied about 800,000 women and found over a thousand genetic signals that influence when menstruation starts.
  • Some women have a much higher chance of starting their periods too early or too late based on their genetic makeup, suggesting that genes play a big role in this process!

Pharmacodynamic Effect of mTOR Inhibition-based Immunosuppressive Therapy on T- and B-cell Subsets After Renal Transplantation.

Transplant Direct

July 2024

Pediatric Gastroenterology and Hepatology, Department of Pediatrics and Adolescent Medicine, University Hospital Erlangen, Friedrich-Alexander-University Erlangen-Nuremberg, Erlangen, Germany.

Background: The mammalian target of rapamycin inhibitor (mTORi) therapy after kidney transplantation is solely monitored pharmacokinetically, not necessarily reflecting PI3K-Akt-mTOR pathway blockade efficacy leading to potential under-or overimmunosuppression.

Methods: In this cross-sectional study, phosphoflow cytometry was used to determine the efficacy of mTOR inhibition in peripheral T- and B-lymphocyte subsets by assessing p70S6 kinase (p70S6K) phosphorylation in renal transplant recipients upon treatment with a combination of either mTORi and calcineurin inhibitors (n = 18), or mTORi with mycophenolic acid (n = 9). Nine dialysis patients with end-stage renal disease and 17 healthy age-matched volunteers served as controls.

Aim: Calcineurin inhibitors (CNIs) are the backbone for immunosuppression after solid organ transplantation. Although successful in preventing kidney transplant rejection, their nephrotoxic side effects contribute to allograft injury. Renal parenchymal lesions occur for cyclosporine A (CsA) as well as for the currently favored tacrolimus (Tac).

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest forms of cancer and peritoneal dissemination is one major cause for this poor prognosis. Exosomes have emerged as promising biomarkers for gastrointestinal cancers and can be found in all kinds of bodily fluids, also in peritoneal fluid (PF). This is a unique sample due to its closeness to gastrointestinal malignancies.

Purpose: The purpose of this study was to evaluate RB1 expression and survival across ovarian carcinoma histotypes and how co-occurrence of BRCA1 or BRCA2 (BRCA) alterations and RB1 loss influences survival in tubo-ovarian high-grade serous carcinoma (HGSC).

Experimental Design: RB1 protein expression was classified by immunohistochemistry in ovarian carcinomas of 7,436 patients from the Ovarian Tumor Tissue Analysis consortium. We examined RB1 expression and germline BRCA status in a subset of 1,134 HGSC, and related genotype to overall survival (OS), tumor-infiltrating CD8+ lymphocytes, and transcriptomic subtypes.

Background: Blue light activates melanopsin, a photopigment that is expressed in intrinsically photosensitive retinal ganglion cells (ipRGCs). The axons of ipRGCs converge on the optic disc, which corresponds to the physiological blind spot in the visual field. Thus, a blue light stimulus aligned with the blind spot captures the ipRGCs axons at the optic disc.
