Methods: Nasal epithelium was differentiated from human nasal epithelial stem/progenitor cells and cultured wtih fresh human PBMC. PBMC and supernatants were harvested after 24 and 48 h of co-culture with H3N2-infected nasal epithelium. We used flow cytometry and Luminex to characterize PBMC subpopulations, their activation and secretion of cytokine and chemokines. Results: H3N2 infection of the nasal epithelium associated with significant increase in interferons (IFN-?, IFN-?, IL-29), pro-inflammatory cytokines (TNF-?, BDNF, IL-3) and viral-associated chemokines (IP-10, MCP-3, I-TAC, MIG), detectable already after 24 h. This translates into rapid activation of monocytes, NK-cells and innate T-cells (MAIT and ?? T cells), evident with CD38+ and/or CD69+ upregulation. Conclusions: This system may contribute to in vitro mechanistic immunological studies bridging systemic models and possibly enable the development of targeted immunomodulatory therapies.||Source Title:||Frontiers in immunology||URI:||https://scholarbank.nus.edu.sg/handle/10635/173747||ISSN:||16643224||DOI:||10.3389/fimmu.2018.02514|
