Endometriosis affects approximately 10% of women of reproductive age and is characterized by the presence of endometrial-like tissue outside the uterine cavity, leading to chronic pelvic pain, infertility, and a significant reduction in qua…

Biomarker identification could help in deciphering endometriosis pathophysiology in addition to their use in the development of non invasive diagnostic and prognostic approaches, that are essential to greatly improve patient care. Despite e…

An anonymous online survey in French was used to assess if endometriosis patients would be as ready as unaffected women to donate their menstrual blood for biological research on endometriosis and evaluate potential barriers to such donatio…

BACKGROUND: Endometriosis, affecting 10% of women in their reproductive years, remains poorly understood. Both individual and environmental unexplained factors are implicated in this heterogenous condition. This study aims to examine the in…

Endometriosis is a condition characterized by increased oxidative stress and chronic inflammation, which can be treated with progestins and other progesterone receptor ligands. However, some patients are refractory to this treatment and the…

Abstract Study question Are there any fertility disorders and related local and/or systemic immune changes during the early implantation period in a mouse model of adenomyosis? Summary answer An increase in fertility disorders was observed …

The epithelial to mesenchymal transition (EMT) has been implicated in the development of adenomyosis, along with dysregulated immune responses. Inflammation potentially induces Notch signaling, which could promote this EMT. The objective of…

RESEARCH QUESTION: What is the correlation between serum metabolic profile and endometriosis phenotype? DESIGN: A pilot study nestled in a prospective cohort study at a university hospital, including 46 patients with painful endometriosis …

Endometriosis is a chronic hormono-dependent inflammatory gynecological disease. Endometriosis can be subdivided into three forms: superficial peritoneal implants, endometrioma, and deep infiltrating endometriosis (DIE). Inflammation is a t…

BACKGROUND: Adenomyosis is a benign gynecological disorder associated with subfertility, pelvic pain and abnormal uterine bleeding that have significant consequences for the health and quality of life of women. Histologically, it is defined…

Endometriosis is a frequent, chronic, inflammatory gynecological disease characterized by the presence of ectopic endometrial tissue causing pain and infertility. Macrophages have a central role in lesion establishment and maintenance by dr…

BACKGROUND: Despite intense research, it remains intriguing why hormonal therapies in general and progestins in particular sometimes fail in endometriosis. OBJECTIVE AND RATIONALE: We review here the action mechanisms of progesterone recep…

RESEARCH QUESTION: Is there a follicular fluid-specific metabolic profile in deep infiltrating endometriosis (DIE) depending on the presence of an associated ovarian endometrioma (OMA) that could lead to the identification of biomarkers for…

STUDY QUESTION: What are the effects of B lymphocyte inactivation or depletion on the progression of endometriosis? SUMMARY ANSWER: Skewing activated B cells toward regulatory B cells (Bregs) by Bruton's tyrosine kinase (Btk) inhibition us…

Endometriosis is characterized by the presence of ectopic endometrial cells outside the uterine cavity. Thyroid autoimmunity has been associated with endometriosis. This work investigated the potential pathophysiological link between endome…

The pathophysiology of endometriosis is not completely understood, but an aberrant immune response in the peritoneal environment seems to be crucial for the proliferation of ectopic endometrial cells - as those cells escape apoptosis and pe…

STUDY QUESTION: Is endometriosis associated with aberrant sialylation patterns and what is the potential impact of such anomalies on cell migratory properties? SUMMARY ANSWER: The reduced α-2,6 sialylation patterns in the peritoneal fluid …

BACKGROUND: Adenomyosis (ADE) is an enigmatic uterine disorder. Several types have been previously described: diffuse adenomyosis (DIF-ADE), focal adenomyosis (FOC-ADE), and association of focal and diffuse lesions (FOC/DIF-ADE). Abnormal i…

The redox-sensitive nuclear factor erythroid-derived 2-like 2 (NRF2) controls endogenous antioxidant enzymes' transcription and protects against oxidative damage which is triggered by inflammation and known to favor progression of endometri…

STUDY QUESTION: Is oxidative stress associated with the A disintegrin and metalloproteases (ADAM) metallopeptidase domain 17 (ADAM17)/Notch signalling pathway and fibrosis in the development of endometriosis? SUMMARY ANSWER: Oxidative stre…

The physiopathology of endometriosis is not completely understood and its progression is associated with a local and systemic inflammatory reaction. It is important to clarify the potential role of the immune system to better understand its…

OBJECTIVE: Mitogen-activated protein kinases (MAPKs) are involved in the proliferation and survival of endometriotic lesions. Vemurafenib (PLX4032) is a novel protein kinase inhibitor that targets BRAF, a member of the MAPK pathway. The pre…

We investigated whether serum osteopontin (OPN) levels are different according to specific phenotypes of adenomyosis and endometriosis. We conducted a prospective laboratory study in a university referral center for endometriosis between Ma…
