IL17RE
Overview
IL17RE (Interleukin 17 Receptor E) encodes a receptor for IL-17C involved in epithelial innate immune responses. In the cancer immunotherapy context, IL17RE was identified among a pre-therapy gene expression signature associated with response to anti-PD-1 therapy in melanoma, nominated as an immune-environment modulator.
Alterations observed in the corpus
- Highly expressed pre-therapy in CR/PR vs PD patients in the 189-DEG responder signature (q < 0.20) in advanced melanoma patients treated with nivolumab (CA209-038 trial, n=68); nominated as an immune-environment modulator. PMID:29033130
Cancer types (linked)
- Skin Cutaneous Melanoma (SKCM): Pre-therapy IL17RE expression was differentially elevated in responders vs non-responders to nivolumab in the CA209-038 trial (n=68 advanced melanoma, paired pre-/on-therapy biopsies). PMID:29033130
Co-occurrence and mutual exclusivity
- Co-expressed with FGFR3 and IL17RC in the pre-therapy 189-DEG responder set, suggesting shared immune-regulatory context. PMID:29033130
Therapeutic relevance
- No direct targeted therapy against IL17RE is reported in this corpus. High pre-therapy expression may serve as a predictive biomarker for anti-PD-1 response in melanoma, pending validation. PMID:29033130
Open questions
- The 189-DEG analysis was limited by small sample size; IL17RE as a standalone predictive biomarker requires prospective validation.
- The mechanistic basis for IL17RE expression predicting anti-PD-1 response in melanoma is not established. PMID:29033130
