(A) Composition of OA and PO among total free FAs in sera before and after influenza virus infection (n = 8).
(B) Body weight change in mice fed with control chow or SSI-4 chow for 1 week following influenza infection.
(C) Flow cytometry analysis of GC B cells in mediastinal lymph nodes at day 11 following infection. Right: the frequencies of GC B cells.
(D) The frequencies of Bcl6+ expression among B cells in mediastinal lymph nodes.
(E) The frequencies of B220intCD138+ plasmablasts.
(F) Flow cytometry analysis of Tfh cells in mediastinal lymph nodes. Right: the frequencies of CXCR5+Bcl6hi Tfh among CD4+ T cells in mediastinal lymph nodes.
(G) Influenza virus-specific antibodies IgG, IgG1, IgG2c, and IgM in sera were measured using ELISA.
p values were calculated using Student’s t test (A–G). Results are representative of three (B–G) independent experiments. Error bars represent SEM.
