We’re thrilled to keep the momentum going with the seventh session of the SFRR-E ECR webinar series, “Emerging Leaders in Redox Biology”, taking place on Tuesday, 3rd March, 2026.
This series is dedicated to showcasing early-career researchers who are pushing the boundaries of redox biology. We’re looking forward to another engaging afternoon of learning, discussion, and connection.
This time, we’ll explore the captivating topic of “TRX to the core”, with presentations from two exceptional researchers - Karoline Scholzen and Sabrina de Brasi-Velasco.
Join us at 15:00 CET for an exciting deep dive into cutting-edge redox research!
Control of redox signaling by TXNRD1 studied at single cell level
Karoline Scholzen, MSc
Division of Biochemistry, Department of Medical Biochemistry and Biophysics, Karolinska Institutet, Stockholm, Sweden
Karoline is a PhD student at the Karolinska Institutet in Stockholm, Sweden. She is supervised by Elias Arnér, in the Division of Biochemistry in the Department of Medical Biochemistry and Biophysics. She studied Biochemistry at the University of Heidelberg in Germany and obtained her Master’s degree in 2021. Throughout her Bachelor and Master theses she explored different aspects of redox biochemistry, with the latter focused on the thioredoxin system under supervision of Elias Arnér. In her Master thesis she co-developed, together with the Thorn-Seshold group, small chemical probes for measuring the activity of thioredoxin and thioredoxin reductase in cells. During her PhD she continued working on these probes, pushing the boundaries of methodology for studying thioredoxin reductase. One of her main projects is combining activity measurements on single-cell level with single-cell transcriptomics, hoping to improve the understanding of redox control within single-cells.
New role for thioredoxins beyond thiol-disulfide exchange: AtTRXo1 acting as Depersulfidase in Plants
Sabrina De Brasi Velasco, PhD
Plant Pathology Group; Department of Stress Biology and Plant Pathology. Center for Soil Science and Applied Biology of the Segura - Spanish National Research Council (CEBAS-CSIC), Murcia, Spain
Sabrina is a postdoctoral researcher at Centro de Edafología y Biología Aplicada del Segura (CEBAS-CSIC). She completed her BSc in Biochemistry and MSc in Regenerative Biomedicine at the University of Granada. She obtained her PhD in Plant Biology from the University of Murcia in 2023, with a thesis focused on the redox protein Thioredoxin o1 (TRXo1) and its role in the regulation of autophagy, ABA hormone signaling, persulfidation, and plant adaptation to to abiotic stress situations, such as growth under salinity conditions. Her research explores redox regulation in plants, particularly the involvement of thioredoxins in stress-induced autophagy and abiotic stress adaptation, using Arabidopsis thaliana as a model. Her recent work on TRXo1 and protein persulfidation in plants was published in Redox Biology. She is currently expanding her research toward biotic stress within the Plant Pathology group at CEBAS-CSIC, studying genetic resistance of viruses in plants.
