Interleukin 1 regulates its own receptors in human endometrial cells via distinct mechanisms

Considering IL1's immunomodulatory, proangiogenic and tissue remodeling properties, and its role as an embryonic signal, modulation of endometrial cell responsiveness to IL1 via the concomitant regulation of its own activating and inhibitory receptors and receptor antagonist may represent an important regulatory mechanism of IL1-induced physiological changes occurring in the human endometrium during the normal menstrual cycle and embryo development.
