Early Epidemiologic and Immune Predictors of Atopic Dermatitis: Reduced Cord Blood Regulatory B10 Cells in the Munich Atopy Prediction Study (MAPS)

Allergy, EarlyView.
In this prospective birth cohort from Munich, comprehensive clinical assessments and longitudinal lifestyle questionnaires were combined with cord blood immune profiling. Infants who later developed AD showed altered cord blood immune signatures, including reduced CD4+ T cells, increased B cells and markedly decreased Breg cells. Epidemiologic factors,

Apomixis in Genista salzmannii DC. (Fabaceae) [PDF]

, 1991
Genista apomixis is described for the first time in two populations of Genista salzmannii DC.: the first is diploid and the second one tetraploid. There was no female meiosis and the megaspore mother cell functioned as an unreduced megaspore, which led ...

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing
