Necroptosis in SJS/TEN: RIPK1 and RIPK3 Expression and Implications for Disease Pathogenesis

Year: 2026

Type: article

Abstract: Necroptosis has been implicated in the pathogenesis of Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), with prior studies demonstrating tissue-level involvement of receptor-interacting protein kinases RIPK1 and RIPK3. However, their systemic expression in the circulatory compartment remains incompletely characterized. The objective of this study is to evaluate circulating levels of RIPK1 and RIPK3 in patients with SJS/TEN and explore their potential association with diseases. Serum samples from patients with SJS/TEN and control groups were analyzed for RIPK1 and RIPK3 levels using ELISA. Group differences were assessed using non-parametric statistical methods. Circulating levels of RIPK1 and RIPK3 were elevated in patients with SJS/TEN compared with controls. These findings were consistent across analyses; however, variability within groups and overlap between cohorts were observed. These results suggest an association between increased circulating RIPK1 and RIPK3 levels and SJS/TEN. Given the limited sample size, heterogeneous control populations, and lack of functional or phosphorylation-specific assays, these findings should be considered exploratory. Further studies incorporating larger cohorts and mechanistic validation are needed to clarify the role of necroptosis-related pathways in the systemic manifestations of SJS/TEN.
