BACKGROUND There is a growing body of epidemiologic literature reporting associations between atmospheric pollutants and reproductive outcomes, particularly birth weight and gestational duration. OBJECTIVES The objectives of our international workshop were to discuss the current evidence, to identify the strengths and weaknesses of published epidemiologic(More)
The aim of this study was to examine correlations between vaginal inflammatory cytokines (IL-1alpha, IL-1beta, IL-6 and IL-8) and pregnancy-related traits (gestational age, birth-weight, BMI, weight gain during pregnancy and vaginal pH). Differences in correlation coefficients were examined among bacterial vaginosis (BV) status and the presence or absence(More)
Regulatory T cells (Tregs) having CD4+ CD25+ Foxp3+ or CD4+ IL-10+ (Tr1) phenotype and capable of inducing anergy towards self- and alloantigens play an important role in autoimmunity, as well as in tolerance of allografts, pregnancy and cancer. Both thymus-derived T CD4+ CD25+ Foxp3+ natural cells and peripherally-induced T CD4+ CD25+ Foxp3+ cells prevent(More)
The phenomenon of pregnancy can be compromised by a number of complications, such as threatened abortion, recurrent spontaneous miscarriage, preeclampsia, and preterm delivery. Research conducted during the last decade has opened up the possibility that cellular immune effectors may underlie such pregnancy complications. Particularly interesting are the(More)
Progesterone (P) has been widely used in an attempt to prevent threatened miscarriage, recurrent miscarriage and pre-term labour. Successful pregnancy depends on maternal tolerance of the fetal "semi-allograft". Along with its endocrine effects, P also acts as an "immunosteroid", by controlling the bias towards a pregnancy protective immune milieu. A(More)
INTRODUCTION Our previous study revealed that anti-inflammatory cytokine gene polymorphisms increase the risk of spontaneous preterm delivery (PD) in a population of Polish women. Different genetic background of PD due to preterm premature rupture of membranes (pPROM) than PD without pPROM has been suggested. The aim of this study was to examine the(More)
The acceptance of paternally-derived alloantigens during pregnancy and escape from host immunosurveillance by cancer are based on similar immunological mechanisms. Among them both natural and peripherally-induced T CD4+ CD25+ Foxp3+ and Tr1 regulatory cells (Tregs) play important role. Interactions of Tregs with other immunocytes including dendritic cells,(More)
PROBLEM The initiation of labor is accompanied by alterations in the level of maternal immune tolerance toward fetal antigens. It is a complex molecular response leading to a brief activation of the maternal immune system with an accompanying capacity to restrict this same activation. The aim of our study was to evaluate the subpopulation of regulatory T(More)
PROBLEM RCAS1 (a receptor-binding cancer antigen expressed on SiSo cells) is a membrane protein present also in a soluble form that seems to be responsible for the suppression of the cytotoxic immune response during gestation. The present study evaluates the decidual immunoreactivity level of RCAS1 and the serum level of RCAS1 with respect to the(More)
PROBLEM Pre-eclampsia seems to be related to the disturbance of immune tolerance regulation during pregnancy. Receptor-binding cancer antigen expressed on SiSo cells (RCAS1) decidual level alterations were concomitant with changes in immune cell number and activity in decidua. As decidual immunomodulating activity participates in the development of immune(More)
