Unviling the role of PD-1-PD-L1 Pathway in Endometriosis Progression and Therapy
The role of immune system in Endometriosis, a chronic inflammatory disease is complex, involving both protective and harmful effects. A key player in this process is PD-1 (programmed cell death protein 1), a protein found on T cells that regulates immune responses by inhibiting…

By Eylül GÜN
While the exact cause of endometriosis is still debated, various theories are being investigated. One approach focuses on the immune system. Regulatory T-cells (Tregs) are crucial in suppressing inflammatory immune responses and preventing autoimmune diseases, allergies, infections, and cancer. Knez…

White blood cell neutrophils link to immunosuppressive environment in ovarian endometrioma
By Yu Yu
Recently the contribution of neutrophils to the pathogenesis of endometriosis has been suggested. Several observations fuelled this suggestion, such as the accumulation of neutrophils in the peritoneal fluid of ovarian endometriosis; neutrophil extracellular traps were found in the peritoneal fluid of…

Heme impairs macrophage phagocytosis
By Yu Yu
Heme is an iron-containing molecule that carries oxygen in the blood and also serves many essential biological proteins. It is released from ruptured erythrocytes during hemolysis. If not chelated, heme can cause harmful oxidative damage and inflammation. Thus, heme is…

Correlation between Treg cells and peritoneal lesions in women with ovarian endometrioma
By Yu Yu
It is increasingly suggested that defective immune response is responsible for the survival and development of ectopic endometrial cells into endometriosis. In women with endometriosis, the immune system fails to create an inflammatory process that destroys endometrial cells at the…

A newly found relationship between estrogen signalling and immune dysregulation in endometriosis
By Yu Yu
It is believed that endometriosis progression is "at least partly" due to dysregulation of immune cells resulting in the poor clearance of ectopic endometrial debris. In particular, aberrant macrophage function was found to be important in the establishment of endometriosis, since…

Local inflammation and disease severity in endometriosis
By Yu Yu
During inflammation, immune cell receptors recognize endogenous molecules called danger-associated molecular patterns (DAMPs) or ‘alarmins’. This process reflects tissue damage and is mediated upon cell death in the condition of strong inflammation. HMGB1 and IL-33 are important DAMP molecules. Recently,…
