Hyper-IgE syndrome (HIES) is a very rare primary immune deficiency characterized by elevated serum IgE levels, recurrent bacterial infections, chronic dermatitis, and connective tissue abnormalities. Autosomal dominant (AD) HIES involves a mutation in signal transducer and activator of transcription 3 (STAT3) that leads to an impaired T<SUB>H</SUB>17 response. STAT3 signaling is also involved in the function of RORγt<SUP>+</SUP> type 3 innate lymphoid cells (ILC3s) and RORγt<SUP>+</SUP>T<SUB>H</SUB>17 cells. The aim of this study was to investigate the role of innate immune cells such as innate lymphoid cells (ILCs), granulocytes, and monocytes in a patient with HIES. Peripheral blood mononuclear cells (PBMCs) from a patient with HIES and three age-matched healthy controls were obtained for the analysis of the innate and adaptive immune cells. The frequencies of ILCs in PBMCs were lower in the patient with HIES than in the controls. Moreover, granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-17A produced by ILC3s in PBMCs were lower in the patient with HIES than the controls. Compared with the controls, classical monocytes (CD14<SUP>+</SUP>CD16<SUP>low</SUP>), which have a high antimicrobial capability, were also lower in the patient with HIES, while non-classical monocytes (CD14<SUP>low</SUP>CD16<SUP>+</SUP>) as well as intermediate monocytes (CD14<SUP>+</SUP>CD16<SUP>intermediate</SUP>) were higher. Taken together, these results indicate that the impaired immune defense against pathogenic microbes in the patient with HIES might be partially explained by functional defects in ILC3s and inflammatory monocytes.
