Systemic sclerosis (SSc) is characterised by immune dysregulation, vasculopathy and fibrosis, driven by genetic and environmental factors. S100 proteins, which constitute a unique class of calcium-binding proteins, have been shown to be critically implicated in various inflammatory and fibrotic conditions. In this study, we investigated the possible involvement of S100A11 in SSc by examining its cutaneous expression and systemic serum levels, correlating them with key clinical parameters.
