Synergistic effect of IL-33 priming and Gq signaling activation in peritoneal cells derived mast cells

Here we reported that priming of interleukin-33 (IL-33) played a crucial role in the subsequent response of mast cells with Gq signaling. Judging from the levels of cytokines and chemokines, the synergy of IL-33 priming and Gq signaling activation was as high as 53%.

At the entire transcriptional level, high synergy was also observed. This provided evidence supporting the sequential release of IL-33 and Gq signaling activator derived from stromal cells on mast cells in vivo. Likewise, the upregulation of numerous cytokines and chemokines provided enormous support for mast cells to regulate antiviral immunity.
