The aim of this study is to reveal the unknown molecular mechanisms of signaling pathway that regulate activation of basophils, important for type 2 immune response, as well as cytokine production.As a result the regulatory mechanisms were evident that the resting basophils restrain the signal transduction via FcεRI, a receptor for IgE, by negatively regulating the protein levels of signaling molecules and Bcl6, known as transcriptional corepressornegatively regulates cytokine production induced by FcεRI crosslinking in the resting basophils.
