| Outline of Final Research Achievements |
Nose- or nasopharynx-associated lymphoid tissue (NALT) has a unique role that is distinct from that of other lymphoid tissues. During upper airway mucosal immune response, NALT induces a variety of responses, including cytokine and chemokine production and innate immune response, to establish acquired immunity. NALT consists of epithelial cells, epithelium-associated lymphoid tissues such as IgA-committed B cells, innate lymphocytes, T helper cells and dendritic cells. Intranasal immunization has recently been shown to effectively induce a proactive immune response in the local mucosa in addition to a systemic immune response. We provide evidence suggesting that upper airway epitheium as a component of NALT in children may play an important role in inducing innate immunity following viral infection.
