Human spinal enthesis comparative biology of IL-17F and IL-17A reveals greater T-cell IL-17F induction and IL-23 regulation.

ABSTRACT:

Objective

Although IL-17F is important in psoriasis, the rudimentary biology of IL-17F in the human enthesis remains undefined. We aimed to characterise IL-23-dependent and independent IL-17F production from entheseal innate and adaptive T cells and determine the impact of IL-17F on entheseal stromal function and mesenchymal stem cell (MSC) osteogenesis.

Methods

Anti-CD3 and anti-CD28 activated human spinal entheseal T cells were immunophenotyped using multi-parameter flow cytometry and a 36-marker Cytometry by Time-Of-Flight (CyTOF) with cytokine profiling, including IL-17A, IL-17F, and TNF (n = 10). IL-17A, IL-17F, and TNF stimulation of entheseal MSC stromal function was evaluated using RNA-seq and by measuring CCL20 protein expression following stimulation with TNF in co
