Human Mast Cell Sensitization with IgE Increases miRNA-210 Expression.

Background: MicroRNAs (miRNAs) represent important post-transcriptional regulators with a dynamic expression profile during health and disease.

Objectives: We explored the miRNA profile of human mast cells (MCs) during sen-sitization with IgE, during activation through IgE, and relat ed it to prostaglandin D2 synthesis and histamine release.

Method: We investigated the expression pattern of 762 miRNAs during the IgE-mediated sensitization and activation of MCs cultured from CD133+ stem cells that were isolated from allergic asthmatic patients and nonatopic controls.
