Alterations in regulatory T cells induced by specific oligosaccharides improve vaccine responsiveness in mice.
<h4>Unlabelled</h4>Prophylactic vaccinations are generally performed to protect naïve individuals with or without suppressed immune responsiveness. In a mouse model for Influenza vaccinations the specific alterations of CD4(+)CD25(+)Foxp3(+) regulatory T-cells (Tregs) in the immune modul...
