BATOKİNLER
Özet
Yağ dokusu; enerji depolama, termogenez ve metabolik homeostazın düzenlenmesinde görev alan heterojen bir endokrin organdır. Çevresel ve hormonal uyaranlarla beyaz yağ dokusunda gelişen bej adipositler, termojenik özellikleri nedeniyle üçüncü bir adiposit türü olarak değerlendirilmektedir. Kahverengi yağ dokusunun aktivasyonu ve beyaz yağ dokusunun bejleşmesi; UCP1 aracılı termogenez, substrat oksidasyonu ve enerji harcamasındaki artışla ilişkilidir. Kahverengi ve bej adipositlerden salgılanan protein, peptit, lipit, metabolit ve kodlamayan RNA yapısındaki batokinler; otokrin, parakrin ve endokrin etkilerle termogenez, vaskülarizasyon, innervasyon, immün yanıt ve dokular arası metabolik iletişimi düzenleyebilmektedir. Batokinlerin ve reseptörlerinin işlevlerinin açıklığa kavuşturulması; obezite, tip 2 diyabet, dislipidemi, karaciğer yağlanması ve kardiyovasküler hastalıklar için yeni tedavi yaklaşımlarının geliştirilmesine katkı sağlayabilir.
