Etude expérimentale des altérations de la fertilité, du microenvironnement immunitaire et du ciblage de la voie S1P dans un modèle murin d’adénomyose
This study in a mouse model of adenomyosis found that the condition impairs fertility and alters the uterine immune environment, with S1P pathway dysregulation potentially offering a therapeutic target.

This thesis used a tamoxifen-induced murine model of adenomyosis to study how adenomyosis affects fertility, the uterine immune microenvironment, and sphingosine-1-phosphate (S1P) signaling in the absence of associated gynecologic comorbidities. The work reports that diffuse adenomyosis is sufficient to disrupt folliculogenesis, alter estrous cycles, and reduce early markers of endometrial receptivity before the development of progesterone resistance, alongside early and persistent immune remodeling characterized by macrophage reprogramming, redistribution of T-cell subsets, and sustained IL6 overexpression. It further finds that pharmacologic inhibition of the S1P pathway (SKI-5C or FTY720) decreases lesion severity and invasion in a stage- and timing-dependent manner, without globally normalizing immune infiltrates, but with significant modulation of cytokine and invasive pathways including reduced uPA. Relevance to adenomyosis: this paper is centrally about adenomyosis—using a murine adenomyosis model to define fertility impacts, immune microenvironment changes, and S1P pathway targeting.
