The olfactory mucosa has emerged as a promising source of mesenchymal stem cells with neurogenic potential. These cells exhibit neural, glial, and mesenchymal properties, making them attractive candidates for regenerative medicine, particularly in treating neurodegenerative and immunemediated disorders. This systematic review analyzed existing literature on the isolation, characterization, and therapeutic applications of olfactory mucosa mesenchymal stem cells. The review assessed variations in isolation techniques, culture conditions, and differentiation potential, as well as preclinical and clinical applications. Olfactory mucosa mesenchymal stem cells express key neural and mesenchymal markers, including Nestin, SRY-box 2, Olfactory mucosa mesenchymal stem cells represent a promising avenue for neurological and regenerative therapies. Despite their potential, further research is needed to optimize isolation techniques, enhance reproducibility, and navigate regulatory hurdles. Collaborative efforts between researchers, clinicians, and regulatory bodies will be essential to translating OM-MSC research into viable clinical applications. Show less

The evidence supporting an association between traffic-related air pollution exposure and incident childhood asthma is inconsistent and may depend on genetic factors. To identify gene-environment interaction effects on childhood asthma using genome-wide single-nucleotide polymorphism (SNP) data and air pollution exposure. Identified loci were further analyzed at epigenetic and transcriptomic levels. We used land use regression models to estimate individual air pollution exposure (represented by outdoor NO In the European cohorts, 186 SNPs had an interaction P < 1 × 10 Our results indicated that gene-environment interactions are important for asthma development and provided supportive evidence for interaction with air pollution for ADCY2, B4GALT5, and DLG2.
