This study highlights the involvement of the endocannabinoidome in cervical remodeling, emphasizing its relevance in the shift from a nonpregnant to pregnant state and its potential contribution to preterm delivery in inflammatory contexts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Abstract<\/jats:title>\n                    <jats:p>During pregnancy, the main role of the cervix is to isolate the fetus from outside pathogens and maintain the relatively closed system of uterine gestation. Conversely, toward the end of pregnancy, the cervix must be remodeled to increase flexibility and allow the delivery. This process is called cervical remodeling and dysregulation of the process plays a role in premature delivery. The endocannabinoidome plays an important role in several reproductive events; however, its function on cervical tissue throughout pregnancy is poorly understood. The goal of this study was to evaluate the presence and participation of the endocannabinoidome in lipopolysaccharide (LPS)-induced cervical changes. Therefore, we evaluated key components of the endocannabinoidome in cervical tissue from nonpregnant mice and pregnant mice with and without LPS treatment. Using mass spectrometric analysis, we found an increase in anandamide and 2-arachidonoylglycerol in the cervix of pregnant mice when compared to nonpregnant mice. We have also found a reduction in FAAH protein expression in these tissues. Furthermore, when treated with LPS, we observed a reduction in the cervical immunostaining with anti-CB1 and anti-CB2 antibodies. Likewise, using cervix explants from pregnant mice, we found that LPS significantly increased cervical metalloprotease activity and cyclooxygenase 2, which were subsequently modulated by cannabinoid receptor antagonists. Collectively, our findings suggest that an LPS-induced imbalance of cervix endocannabinoidome likely contributes to premature cervical remodeling, which is part of the key components that contribute to premature delivery.<\/jats:p>\n
