Human serum beta(2)-microglobulin levels: correlation with total serum IgG and placental IgG transfer in HIV-infected and non-HIV infected individuals
(Elsevier B.V., 1999-03-01)
The acquisition of maternal immunoglobulin G (IgG) is fundamental to the immune defence of the neonate. the receptor responsible for Ige transfer across the human placenta has also been implicated in the maintenance of IgG ...
Preterm and term neonates transplacentally acquire IgG antibodies specific to LPS from Klebsiella pneumoniae, Escherichia coli and Pseudomonas aeruginosa
(WILEY-BLACKWELL, 2011)
High incidences of Gram-negative bacteria are found in neonatal nosocomial infections. Our aim was to investigate placental transmission of immunoglobulin G (IgG) reactive with lipopolysaccharide from Klebsiella pneumoniae, ...
Passive Acquisition of Protective Antibodies Reactive with Bordetella pertussis in Newborns via Placental Transfer and Breast-feeding
(WILEY-BLACKWELL, 2010)
Although acquisition of anti-pertussis antibodies by the newborn via placental transfer has been demonstrated, a subsequent recrudescence of pertussis infection is often observed, particularly in infants. The present study ...
Placental Transfer of IgG Antibodies Specific to Klebsiella and Pseudomonas LPS and to Group B Streptococcus in Twin Pregnancies
(Wiley-Blackwell, 2015-02-01)
Group B Streptococcus (GBS), Klebsiella spp. and Pseudomonas spp. are important aetiological agents of neonatal infections in Brazil. There is a lack of data in the literature regarding the specific transport of immunoglobulin ...
Placental transfer of IgG and IgG subclass antibodies anti-purified Escherichia coli LPS 016, 06 and 0111
(Blackwell Science Ltd, 1998-06-01)
We evaluated 22 paired maternal and cord sera regarding the presence of IgG and IgG subclasses against purified Escherichia coli LPS O6, O16 and O111 employing ELISA for titre and avidity analysis, isoelectric focusing ...
Transplacental Total IgG Transfer in Twin Pregnancies
(Wiley-Blackwell, 2014-12-01)
ProblemIn twin pregnancies, factors that influence total umbilical cord IgG concentration and IgG transfer ratio are not well known.MethodBlood samples were prospectively collected from 57 twin pregnancies. Stepwise ...
Transfer of antibodies across the placenta and in breast milk from mothers on intravenous immunoglobulin
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We studied the levels of immunoglobulins in colostrum, milk and sera from two common variable immunodeficiency (CVID) mothers (M1 and M2), and in sera from their newborn infants. During pregnancy they continued intravenous ...
Maternal–Foetal Diabetes Modifies Neonatal Fc Receptor Expression on Human Leucocytes
(2016-10-01)
This study investigated the expression of the neonatal Fc receptor (FcRn) in maternal blood, cord blood and placental cells and determined IgG levels in maternal blood and cord blood from diabetic mothers. Peripheral blood, ...
Marcadores da imunomodulação no sangue materno e fetal e nas placentas de mães diabéticas ou com hiperglicemia gestacional leve
(Universidade Estadual Paulista (Unesp), 2016-12-01)
INTRODUÇÃO - Durante a gravidez, a hiperglicemia materna altera a expressão e a transferência de células imunorregulatórias e de imunoglobulinas e o perfil de citocinas na interface materno-fetal. OBJETIVO – Avaliar, em ...
