Key Points

This research aims to investigate the status and function of IL-10-producing pre-Th17-cells in patients with Autosomal Dominant Hyper-IgE Syndrome (AD-HIES).
Analyzed Th17 differentiation in AD-HIES patients
Evaluated IL-10 production in CD4+ T-cells
Assessed activation of pre-Th17-cells by AD-HIES-associated pathogens
Examined B-helper functions of pre-Th17-cells
Pre-Th17 differentiation is arrested at an intermediate stage in AD-HIES patients
IL-10 production by CD4+ T-cells remains unaffected by DN-STAT3 mutations
Pre-Th17-cells promote aberrant IgE production instead of providing protection

Abstract

Th17 differentiation in AD-HIES patients was not completely impaired but arrested at an intermediate stage of IL-10-producing "pre-Th17"-cells. Surprisingly, DN-STAT3 mutations did not inhibit IL-10 production by CD4+T-cells. Pre-Th17-cells were activated by AD-HIES-associated pathogens and possessed B-helper functions, suggesting that they are not protective but may promote aberrant IgE production.
