Previously, we reported decreased Rev-erb\u03b1 expression in decidual stromal cells from pregnant mice with sleep disturbance (SD) and patients of RPL with sleep disturbance (RS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Omics analyses were used to predict the interaction between Rev-erb\u03b1 and glutamine-fructose-6-phosphate amidotransferase 1 (GFPT1). Tunicamycin and peptide-N-glycosidase F and phosphatidylinositol-specific phospholipase C treatment were conducted to analyze the glycosylation modification type of CD58. The coculture between decidual immune cells and decidual stroma cells (DSCs) in which Rev-erb\u03b1, GFPT1, or CD58 was either knockdown or overexpressed was performed to evaluate the crosstalk of CD58\n                      <jats:sup>+<\/jats:sup>\n                      DSCs and CD2\n                      <jats:sup>+<\/jats:sup>\n                      CD4\n                      <jats:sup>+<\/jats:sup>\n                      T cells.

Anti-CD2 antibody significantly decreased the risk of abortion of SD mice, proving a potential therapeutic target for adverse pregnancy outcomes induced by circadian rhythm disruption.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      Rev-erb\u03b1 - GFPT1 - CD58 - CD2 axis played important role in pregnancy maintenance by regulating the crosstalk between DSCs and decidual CD4\n                      <jats:sup>+<\/jats:sup>\n                      T cells.
