Compared to healthy control subjects, SLE patients present significantly higher levels of IL-6, IL-17, IL-12, and IL-23 (Talaat et al., 2015; Furini et al., 2019), which correlate positively and significantly with SLE disease activity index (SLEDAI) score (Talaat et al., 2015). Here, IL6 is linked to systemic lupus erythematosus.
