Thyroid hormone receptor α signaling shapes innate and adaptive immune responses during viral infection.

ABSTRACT:

Objective

Thyroid hormones (TH) are well-known regulators of the immune system. However, the precise immunomodulatory mechanisms of TH action in immune cells remain elusive. In a previous study, an essential role of the TH receptor α (TRα) in regulatory T cell (Treg) immunity was demonstrated, affecting Treg activation at steady state. The present study therefore aimed to unravel the biological relevance of altered TRα action in protective immune responses during disease.

Methods

To assess the role of TRα action in immune responses, especially T cell responses, during disease, different TRα signaling mouse models (TRαKO, complete lack of TRα signaling; TRαGS, lack of canonical signaling) were challenged with influenza virus A/PR8/34, and in-depth immune phenotyping was perfo
