Tryptophan Metabolites as Scavengers of Reactive Oxygen and Chlorine Species

Pteridines, 2002
Upon stimulation with interferon-γ, a typical Thl cell-derived cytokine, human monocyte-dertved macrophages produce neopterin derivatives and in parallel degrade the essential amino acid L-tryptophan to L-kynurenine and subsequently to 3 ...

Impaired contextual fear extinction learning is associated with aberrant regulation of CHD-type chromatin remodeling factors

Frontiers in Behavioral Neuroscience, 2015
Successful attenuation of fearful memories is a cognitive process requiring initiation of highly coordinated transcription programs. Chromatin-modulating mechanisms such as DNA methylation and histone modifications, including acetylation, are key ...

Erwin Schrödinger und die Versuchungen der (Wissenschafts‐)Biografik: Vorurteilsgefüge und Mechanismen der Skandalisierung

Berichte zur Wissenschaftsgeschichte, Volume 49, Issue 2, Page 135-293, June 2026.
Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...
