Abstract

This study uncovers the novel heterogeneity of FOXP3 + regulatory T (Treg) cells and their pivotal role in modulating immune responses during drug-induced allergic reactions, employing cutting-edge single-cell transcriptomics. We established a mouse model for drug-induced allergic reactions and utilized single-cell RNA sequencing (scRNA-seq) to analyze the transcriptomic landscapes of FOXP3 + Treg cells isolated from affected tissues. The study involved both in vitro and in vivo approaches to evaluate the impact of FOXP3 expression levels on the immunoregulatory functions of Treg cells during allergic responses. Techniques included flow cytometry, cluster analysis, principal component analysis (PCA), CCK8 and CSFE assays for cell proliferation, LDH release assays for toxicity, ELISA for cytokine profiling, and CRISPR/Cas9 technology for gene editing. Our findings revealed significant transcriptomic heterogeneity among FOXP3 + Treg cells in the context of drug-induced allergic reactions, with distinct subpopulations exhibiting unique gene expression profiles. This heterogeneity suggests specialized roles in immune regulation. We observed a decrease in the proliferative capacity and cytokine secretion of FOXP3 + Treg cells following allergic stimulation, alongside an increase in reaction toxicity. Manipulating FOXP3 expression levels directly influenced these outcomes, where FOXP3 deletion exacerbated allergic responses, whereas its overexpression mitigated them. Notably, in vivo experiments demonstrated that FOXP3 overexpression significantly reduced the severity of allergic skin reactions in mice. Our study presents novel insights into the heterogeneity and crucial immunoregulatory role of FOXP3 + Treg cells during drug-induced allergic reactions. Overexpression of FOXP3 emerges as a potential therapeutic strategy to alleviate such allergic responses. These findings contribute significantly to our understanding of immune regulation and the development of targeted treatments for drug-induced allergies.

Leben statt zu Überleben: Post-Intensive-Care-Syndrom

Immer mehr Menschen überleben kritische Erkrankungen. Aber Beatmung, Sedierung und die Eindrücke der Intensivstation hinterlassen Spuren. Das Post-Intensive-Care-Syndrom kann die Folge sein. Es ist nicht nur eine Herausforderung für Kliniken, sondern auch Hausarztpraxen. Mit Allgemeinmediziner Prof. Dr. med. Konrad Schmidt sprechen wir in dieser Folge darüber, wie die Überlebenden wieder ins Leben finden können.

ctDNA erkennt minimale Resterkrankung beim Melanom

Die Diagnose einer minimalen Resterkrankung mithilfe zirkulierender Tumor-DNA (ctDNA) könnte auch das Management von Patientinnen und Patienten mit Melanomen im Stadium III bereichern, wie Ergebnisse einer Studie nahelegen – auch wenn die Methode noch nicht perfekt funktioniert.

Lösten In-Ear-Kopfhörer den Lagerungsschwindel aus?

Ein 43-jähriger Patient stellt sich wegen Anfällen von Drehschwindel in der Notaufnahme vor. Diese kämen immer nur dann, wenn er zuvor Musik über Kopfhörer gehört habe. Könnte ein Zusammenhang bestehen?

Weniger Bargeld, weniger Erstickungsnotfälle?

Dadurch, dass immer seltener mit Bargeld gezahlt wird, könnte die Rate an Erstickungsnotfällen bei Kindern zurückgehen. Dieser Hypothese ist ein britisches Forschungsteam in Klinikdaten aus den letzten zweieinhalb Jahrzehnten nachgegangen.
