TSLP Produced by Aspergillus fumigatus-Stimulated DCs Promotes a Th17 Response Through the JAK/STAT Signaling Pathway in Fungal Keratitis.

ABSTRACT:

Purpose

The purpose of this study was to explore the role of thymic stromal lymphopoietin (TSLP) secreted by Aspergillus fumigatus-stimulated dendritic cells (DCs) during the T helper 17 (Th17) immune response, and further clarify the mechanisms contributing to the Th17 immune response of fungal keratitis (FK).

Methods

A carboxyfluorescein diacetate succinimidyl ester assay, PCR, and flow cytometry were performed to detect Th17 differentiation of CD4+ T cells; PCR, ELISA, and Western blot were used to detect the expression of TSLP and JAK/STAT-related proteins; Signaling pathways involved in Th17 response was evaluated using RNA sequence; C57BL/6 mice were infected with A. fumigatus and treated with ruxolitinib or BBI608. Slit-lamp examination, fluorescein staining, and clin
