Changes in the composition of colostrum in the peripartum period focused on the neonate’s immunity can minimize the response of the mammary gland before natural exposure to mastitis pathogens. This research evaluated the oxidative activity of monon

Publikováno v: Pediatric Allergy and Immunology. 20:528-535

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 immunoglobulin therapy (IVI

Pineal melatonin and the innate immune response: the TNF-? increase after cesarean section suppresses nocturnal melatonin production

Autor: Elaine C. Cardoso, Regina P. Markus, Magda Carneiro-Sampaio, G. N. Pontes

Publikováno v: Journal of Pineal Research. 43:365-371

The nocturnal surge of melatonin is the endocrine expression of the circadian system and is essential for organizing the timing of various endogenous processes. Previous works suggest that, in the beginning of a defense response, the increase in circ

Salivary lysozyme levels in patients with primary immunodeficiencies

Autor: Patricia Palmeira, C.M.A. Jacob, Beatriz Tavares Costa-Carvalho, M.A. Kmiliauskis, Christina Arslanian, G. N. Pontes, Magda Carneiro-Sampaio

Publikováno v: Allergologia et Immunopathologia. 33:65-68

Background Lysozyme is a muramidase that acts on the peptideoglycan wall of Gram positive bacteria, causing cell death. It plays part in innate immunity and is present in blood, external fluid, as well in Iysossomal granules of the phagocytes. Primar

Preterm and term neonates transplacentally acquire IgG antibodies specific to LPS from Klebsiella pneumoniae, Escherichia coli and Pseudomonas aeruginosa

Autor: Magda Carneiro-Sampaio, Ana Lúcia Silveira Lessa, G. N. Pontes, Tatiana Braga Brasil, Vera Lúcia Jornada Krebs, Patricia Palmeira

Publikováno v: FEMS immunology and medical microbiology. 62(2)

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, Pseudomonas aeruginosa and

Acquisition of serum antibodies reactive with enterohemorrhagic Escherichia coli virulence-associated factors by healthy Brazilian children and adults

Autor: Cristiane Barros Carbonare, Beatriz E. C. Guth, G. N. Pontes, S B Carbonare, Milene Tino-De-Franco, Patricia Palmeira, Lucy Beatriz Zapata-Quintanilla, Magda Carneiro-Sampaio

Publikováno v: The Pediatric infectious disease journal. 28(12)

Patients with hemorrhagic colitis or hemolytic uremic syndrome due to enterohemorrhagic Escherichia coli (EHEC) develop serum IgM and IgG response to lipopolysaccharide (LPS) and to virulence factors such as intimin. The small numbers of cases of dia

Injury switches melatonin production source from endocrine (pineal) to paracrine (phagocytes) - melatonin in human colostrum and colostrum phagocytes

Autor: Regina P. Markus, Magda Carneiro-Sampaio, Elaine C. Cardoso, G. N. Pontes

Publikováno v: Journal of pineal research. 41(2)

A large number of data show that melatonin has immunomodulatory properties and is produced by immunocompetent cells; also, some evidence suggests a 'feedback' of the activated immune system on the pineal gland. In this paper, we studied immune-pineal

Publikováno v: Scandinavian journal of immunology. 62(4)

We evaluated the ability of human anti-lipopolysaccharide (LPS) O6 immunoglobulin G (IgG) and IgM antibodies to protect mice challenged with Escherichia coli serotype O6:K2ac. Purified whole IgG, commercial gammaglobulin, whole IgM-effluent, pool of
