FcεRI-mediated cytokine and chemokine production by Tespa1-deficient mast cells. (a) WT and Tespa1 KO BMMCs were sensitized with anti-DNP IgE overnight and later stimulated with DNP-BSA for 1, 3, or 24 h. Cytokine and chemokine mRNA expression was measured by RT-PCR. (b) IL-4, IL-5, IL-13, IL-6, TNF, and MCP-1levels were measured by ELISA at 24 h. *, P < 0.05; **, P < 0.01 (Student’s t test). Data are representative of three experiments. Error bars represent SD.
