“Maternal Fulvestrant clinical trial immune responses during pregnancy are critical in programming the future health of a newborn. The maternal immune system is required to accommodate fetal immune tolerance as well as to provide a protective defence against infections for the immunocompromised mother and her baby during gestation and lactation. Natural immunity and antibody production by maternal B

cells play a significant role in providing such immunoprotection. However, aberrations in the B cell compartment as a consequence of maternal autoimmunity can pose serious risks to both the mother and her baby. Despite their potential implication in shaping pregnancy outcomes, the role of B cells in human pregnancy

has been poorly studied. This review focuses on the role of B cells and the implications of B cell depletion therapy in pregnancy. It highlights the evidence of an association between aberrant B cell compartment and obstetric conditions. It also alludes to the potential mechanisms that amplify these B cell aberrances and thereby contribute to exacerbation of some maternal autoimmune conditions and poor neonatal outcomes. Clinical and experimental evidence suggests strongly that maternal autoantibodies contribute directly to the pathologies of obstetric and neonatal conditions that have significant implications for the lifelong health of a newborn. The evidence for clinical benefit and safety of B cell depletion therapies in pregnancy is reviewed, and an argument DMXAA price is mounted for further clinical evaluation of B cell-targeted therapies in high-risk pregnancy, with an emphasis on improving neonatal outcomes and prevention of neonatal conditions such as congenital heart block and fetal/neonatal alloimmune thrombocytopenia. An individual’s lifetime

health is critically programmed during the gestational period. During pregnancy, the maternal immune system is required not only to accommodate the allogeneic fetus but also to maintain protection against Resminostat harmful infections in the otherwise immunocompromised mother and immuno-incompetent fetus [1]. The roles of innate and cell-mediated immunity, including natural killer, T helper type 1 or 2 (Th1/Th2) cells and regulatory T cells (Treg) are well documented in pregnancy [2, 3]. In contrast, there has been little focus on the role of B cells and antibody-mediated immunity. This is surprising, given the fundamental role of B cells as effectors and regulators of both innate and adaptive immune responses [4, 5]. Maternal B cells also provide a vital source of antibody-mediated protective immunity for the mother and her baby during both pregnancy and lactation [6].
