Melatonin; uyku-d\u00f6ng\u00fcs\u00fcn\u00fc d\u00fczenleyen hormonal bir yap\u0131 olmas\u0131n\u0131n \u00f6tesinde, antioksidan ve imm\u00fcnomod\u00fclat\u00f6r \u00f6zellikleriyle uzun s\u00fcredir bilimsel mercek alt\u0131nda yer almakta.

TLR4, patojenler veya h\u00fccresel hasar sinyallerini tan\u0131yan ve inflamasyon tetikleyen \u00f6nemli bir resept\u00f6rd\u00fcr. Yumurtal\u0131k kanseri ba\u011flam\u0131nda, t\u00fcm\u00f6r ortam\u0131nda kronik iltihab\u0131n hastal\u0131\u011f\u0131n ilerlemesine katk\u0131 sa\u011flad\u0131\u011f\u0131 bilinmektedir.

TLR4 sinyal yolunda MyD88 ve TRIF olmak \u00fczere iki ana adapt\u00f6r molek\u00fcl yer al\u0131r. Bunlar, farkl\u0131 ancak tamamlay\u0131c\u0131 i\u015flevler \u00fcstlenerek pro-inflamatuar genlerin ifade edilmesini sa\u011flarlar. MyD88 ba\u011f\u0131ml\u0131 yol; h\u0131zl\u0131 NF-\u03baB aktivasyonu ve sitokin \u00fcretiminden sorumluyken, TRIF arac\u0131l\u0131\u011f\u0131yla alternatif interferon yan\u0131tlar\u0131 ve ge\u00e7 evre inflamatuar genler devreye girer.
