Abstract

Immune activation is a hallmark of systemic sclerosis (SSc). However, the immunological alterations that occur in preclinical and non-fibrotic SSc and that differentiate these subjects from those with primary Raynaud's phenomenon (PRP) or healthy controls (HC) are poorly defined. We isolated CD56+ (NK/NKT-like) cells from HC, patients with PRP, early SSc (EaSSc) and definite SSc without skin or lung fibrosis. Cytokine production upon different activating stimuli was measured via a multiplex immuno assay. Clearly discriminative patterns among the different stages of SSc were most markedly observed after TLR1/2 stimulation, with increased IL-6, TNF-α and MIP-1α/CCL3 production in definite SSc patients as compared to HC and/or PRP. Initial alterations were observed in EaSSc patients with an intermediate secretion pattern between HC/PRP and definite SSc. CD56+ cells from patients at different stages of SSc differentially respond to TLR stimulation, highlighting the relevance of natural immunity in the developmental and pre-fibrotic SSc.
