Protein corona–mediated targeting of nanocarriers to B cells allows redirection of allergic immune responses
2018
Background Nanoparticle (NP)–based vaccines are attractive immunotherapy tools because of their capability to codeliver antigen and adjuvant to antigen-presenting cells. Their cellular distribution and serum protein interaction ("protein corona") after systemic administration and their effect on the functional properties of NPs is poorly understood. Objectives We analyzed the relevance of the protein corona on cell type–selective uptake of dextran-coated NPs and determined the outcome of vaccination with NPs that codeliver antigen and adjuvant in disease models of allergy. Methods The role of protein corona constituents for cellular binding/uptake of dextran-coated ferrous nanoparticles (DE…
Cinnamon extract inhibits allergen-specific immune responses in human and murine allergy models.
2019
Background Ceylon cinnamon has been shown to possess anti-inflammatory properties in many diseases including allergic inflammation. Objective The aim of this study was to analyse in more detail the effects of cinnamon extract (CE) and its major compounds p-cymene and trans-cinnamaldehyde (CA) on allergen-specific immune responses in vitro and in vivo. Methods Therefore, monocyte-derived mature dendritic cells (DC) from grass or birch pollen allergic donors were pulsed with the respective allergen in the presence or absence of CE, p-cymene, CA or the solvent ethanol and co-cultured with autologous CD4+ T cells. Furthermore, basophil activation test was performed with or without CE or ethanol…
