PG - 838-843 LID - 10.1248/bpb.b21-00065 [doi] AB - The excessive ingestion of oxidized dietary oils may exacerbate some allergic diseases. We previously reported that oxidized olive oil exacerbates active cutaneous anaphylaxis (ACA), one of the immediate allergic reactions. This study was conducted to clarify the effects of oxidized olive oil on the T cell response during ACA. BALB/c female mice were orally administered naturally oxidized olive oil once every 2 d for 2 weeks after ovalbumin (OVA)/aluminum hydroxide gel sensitization, after which ACA was elicited by intracutaneous administration of OVA into the ear auricles. Compared with fresh olive oil, oxidized olive oil administration increased the antigen-specific immunoglobulin E (IgE) antibody titer 2 weeks after OVA-sensitization and vascular hyperpermeability increased due to ACA. In the oxidized olive oil-administered mice, the mRNA expression levels of T-helper 2 (Th2) cytokines, interleukin (IL)-4, -5, -6, and -10, in the lymph nodes increased, as did the proportion of cluster designation (CD)3(+)CD4(+) cells in the spleen and lymph nodes. In CD3(+)CD4(+) cells, the mRNA expression levels of IL-4 and GATA-binding protein 3 (GATA3), the master regulator of Th2, were higher in the oxidized olive oil-group. Antigen-stimulated specific IL-4 production was promoted in CD3(+)CD4(+) cells of oxidized olive oil-administered mice. This suggests that oxidized olive oil exacerbates ACA by promoting Th2 dominance in immediate allergic diseases.
