Abstract

Objective: Psoriasis is a common, chronic and recurrent disease which can affect skin and also joints. Although the etiopathogenesis of psoriasis has not precisely determined, the most supported mechanism is inflammation triggered by any factor. Toll like receptors (TLRs) family described in recent years is known to play a critical role in host immunity against a wide variety of pathogens. In our study, we aimed to reveal possible relationships of some TLR gene polymorphisms with psoriasis in this patient group.Methods: A hundred patients who diagnosed with psoriasis and 173 healthy controls were included in the study which known to be without inflammatory disease, TLR2 gene Arg677Trp, Arg753Gln, -196-174 del and TLR4 gene Asp299Gly, Thr399Ile polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism method, patient and control groups were compared in terms of gene polymorphisms mentioned. Results: In this study, it was determined psosiasis has a statistically significant relationship with GA genotype and A allele in TLR2 Arg753Gln polymorphism. Furthermore, when the patient and control groups were compared for -196-174 del gene polymorphism, it was determined that ins/del genotype had a protective effect. Conclusion: We think that variant alleles in the TLR2 gene may play an important role in the molecular etiopathogenesis of psoriasis.

Özet

Amaç: Psoriasis; sık rastlanan, deri ile birlikte eklemleri de etkileyebilen, kronik ve tekrarlayıcı bir hastalıktır. Psoriasisin etiyopatogenezi tam olarak açıklanamamış olsa da en çok desteklenen mekanizma, herhangi bir etkenle tetiklenen inflamasyondur. Son yıllarda tanımlanan toll benzeri reseptör (TLR) ailesinin oldukça geniş çeşitlilikteki patojenlere karşı konakçı bağışıklığında kritik bir rol oynadığı bilinmektedir. Çalışmamızda, bu hasta grubunda bazı TLR gen polimorfizmlerinin, psoriasis ile olan muhtemel ilişkilerinin ortaya konmasını amaçladık.Yöntemler: Psoriasis tanısı almış 100 hasta ile otoimmün veya inflamatuvar hastalığı olmadığı bilinen 173 hasta içeren sağlıklı kontrol grubu çalışmaya dahil edilmiş olup TLR2 geni Arg677Trp, Arg753Gln, -196-174 del ve TLR4 geni Asp299Gly, Thr399Ile polimorfizmleri polimeraz zincir reaksiyonu-restriksiyon parça uzunluk polimorfizmi yöntemi ile belirlenmiş, hasta ve kontrol grubu sözü edilen gen polimorfizmleri açısından karşılaştırılmıştır. Bulgular: Bu çalışma ile psoriasisin, TLR2 Arg753Gln polimorfizminde GA genotipi ve A aleli ile istatistiksel olarak anlamlı bir ilişkide olduğu saptanmıştır. Ayrıca -196-174 del gen polimorfizmi için hasta ve kontrol grubu karşılaştırıldığında, ins/del genotipine sahip olmanın koruyucu etki yaptığı belirlenmiştir. Sonuç: TLR2 genindeki varyant alellerin, psoriasisin moleküler etiyopatogenezinde önemli rolü olabileceğini düşünmekteyiz.
