Abstract

Abstract
Alopecia areata (AA) is a common, has organ-specific semptoms and an autoimmune disease that targets hair follicles and causes scarring, hair or hair loss. Although the etiopathogenesis of AA has not been clarified yet; In addition to attitude, psychological factors and persistence factors, autoimmune and inflammatory cells have a polygenic character in which genes are effective. Immunological hair follicle dysfunction process in AA are controlled by activated T cells. It is thought that cytokines released in T cells may cause hair loss in AA. Studies have reported that various genes of the immune system, such as interleukin and cytotoxic T lymphocyte-associated antigen 4 (CTLA4), are effective in the development of the cell membrane, and dysfunction of the CTLA-4 antigen may be associated with various diseases. The CTLA-4 gene polymorphism is thought to be associated with impaired control of T cell proliferation, and this gene is thought to be a candidate gene for susceptibility to autoimmunity. This study was conducted to investigate whether CTLA4 CT60 A/G and +49AG polymorphisms have a role in susceptibility to Alopecia Areata. 195 patients and 173 healthy volunteer controls were included in the study, and genotype and allele frequencies were determined by PCR-RFLP method. The obtained data were analyzed with OpenEpi. Our results showed that the +49AG polymorphism was not associated with AA susceptibility in the Turkish population, but the CT60 polymorphism might be associated with AA susceptibility. However, more studies are needed to confirm our results.

Özet
Alopesi areata (AA), saç foliküllerini hedef alan ve yara izi, saç veya saç dökülmesine neden olan yaygın, otoimmün bir hastalıktır. AA'nın etyopatogenezi henüz netlik kazanmamış olmakla birlikte; Tutum, psikolojik faktörler ve kalıcılık faktörlerine ek olarak, otoimmün ve enflamatuar hücreler, genlerin etkili olduğu poligenik bir karaktere sahiptir. AA'daki kıl folikülü disfonksiyon mekanizmaları immünolojiktir ve aktifleştirilmiş T hücreleri tarafından kontrol edilir. T hücrelerinde salınan sitokinlerin AA'da saç dökülmesine neden olabileceği düşünülmektedir. Çalışmalar, interlökin ve sitotoksik T lenfosit ilişkili antijen 4 (CTLA4) gibi bağışıklık sisteminin çeşitli genlerinin hücre zarının gelişiminde etkili olduğunu ve CTLA-4 antijeninin işlev bozukluğunun çeşitli hastalıklarla ilişkili olabileceğini bildirmiştir. . CTLA-4 gen polimorfizminin, T hücre proliferasyonunun bozulmuş kontrolü ile ilişkili olduğu ve bu genin otoimmüniteye yatkınlık için aday bir gen olduğu düşünülmektedir. Bu çalışma, CTLA4 +49AG ve CT60 polimorfizmlerinin Alopesi Areata'ya duyarlılıkta rolü olup olmadığını araştırmak amacıyla yapılmıştır. 195 hasta ve 173 sağlıklı kontrol çalışmaya dahil edildi ve genotip ve alel frekansları PCR-RFLP yöntemi ile belirlendi. Elde edilen veriler OpenEpi ile analiz edilmiştir. Sonuçlarımız, Türk popülasyonunda +49AG polimorfizminin AA duyarlılığı ile ilişkili olmadığını, ancak CT60 polimorfizminin AA duyarlılığı ile ilişkili olabileceğini göstermiştir. Ancak, sonuçlarımızı doğrulamak için daha fazla çalışmaya ihtiyaç vardır.
