Amaç: Psoriasis, tekrarlayan ve pullu plaklarla karakterize edilen yaygın bir kronik inflamatuar deri hastalığıdır. IL-17, hastalığın patogenezinde merkezi bir rol oynamakta olup, IL-17A’yı hedefleyen monoklonal bir antikor olan Secukinumab bu amaçla yaygın olarak kullanılmaktadır. Uzun zincirli kodlamayan RNA’lar (lncRNA’lar), keratinosit proliferasyonu ve bağışıklık yanıtlarının düzenlenmesinde rol oynamaktadır; ancak IL-17 blokajına verdikleri yanıt hâlâ net olarak bilinmemektedir. Bu çalışma, bir psoriasis hücre kültürü modelinde IL-17 inhibitörü Secukinumab’ın, keratinosit proliferasyonu ve inhibisyonunda rol oynayan MEG3 ve MSX2P1 adlı iki lncRNA’nın ekspresyonu üzerindeki etkisini araştırmayı amaçlamaktadır.

Gereç ve yöntem: HaCaT hücreleri, inflamatuar koşulları taklit etmek amacıyla lipopolisakkarit (LPS) ile uyarılmış ve ardından çeşitli dozlarda Secukinumab ile tedavi edilmiştir. Hücre canlılığı 24, 48 ve 72 saatlerde CCK-8 yöntemi ile değerlendirilmiş ve 7,5 mg/ml konsantrasyonu LD₅₀ olarak belirlenmiştir. RNA izolasyonu yapılmış ve gen ekspresyon seviyeleri qRT-PCR yöntemiyle ölçülmüştür.

Bulgular: Secukinumab tedavisi sonrası, kontrol grubuna kıyasla MEG3 ekspresyonunda yaklaşık 20 kat, MSX2P1 ekspresyonunda ise yaklaşık 190 kat azalma gözlenmiştir. Bu bulgular, IL-17 inhibisyonunun, proliferasyon ve inflamasyonla ilişkili lncRNA’ların modülasyonu yoluyla keratinosit fonksiyonunu etkileyebileceğini düşündürmektedir.

Sonuç: Secukinumab keratinositlerde önemli lncRNA’ların ekspresyon düzenini değiştirebilmektedir. Psoriasis’in klinik yönetiminde bu değişikliklerin rolünü ve ilişkili moleküler yolları aydınlatmak için ileri çalışmalara ihtiyaç vardır.

Purpose: Psoriasis is a common chronic inflammatory skin disease characterized by recurrent, scaly plaques. IL-17 plays a central role in its pathogenesis, and Secukinumab—an anti-IL-17A monoclonal antibody—is widely used for treatment. Long non-coding RNAs (LncRNAs) regulate keratinocyte proliferation and immune responses, yet their response to IL-17 inhibition remains unclear. This study aimed to investigate the effect of Secukinumab on MEG3 and MSX2P1 lncRNA expression in a psoriasis cell culture model.

Materials and methods: HaCaT cells were stimulated with lipopolysaccharide (LPS) to mimic inflammatory conditions, followed by treatment with various doses of secukinumab. Cell viability was assessed at 24, 48, and 72 hours using CCK-8, with 7.5 mg/ml determined as the LD₅₀ concentration. RNA was isolated, and gene expression levels were measured via qRT-PCR.

Results: The results demonstrated an approximately 20-fold reduction in MEG3 expression and an approximately 190-fold reduction in MSX2P1 expression following secukinumab treatment compared to the control group. These findings suggest that IL-17 inhibition may influence keratinocyte function through the modulation of LncRNAs associated with proliferation and inflammation.

Conclusion: Secukinumab appears to alter the expression patterns of key LncRNAs in keratinocytes. Further investigation is warranted to clarify the downstream molecular pathways involved and their relevance in the clinical management of psoriasis.
