Abstract in Portuguese
A Asma vem apresentando taxas de prevalência crescentes em todo o mundo. Os objetivos deste trabalho são avaliar a presença de elementos celulares e humorais indicativos em sangue e colostro de mães asmáticas e saudáveis e no sangue de cordão umbilical de seus recém-nascidos (RN). Observamos menor produção de IgG pelas mães asmáticas. Células dendríticas de mães asmáticas possuem maior expressão de CD80 e CD86. Mães asmáticas possuem mais células de memória central. Linfócitos T CD4+ de mães asmáticas produzem níveis maiores IFN-g. Células CD3+ e CD4+ de mães asmáticas produziram mais IL-13. Mães saudáveis produziram maiores quantidades de IL-10. Concluímos que mães asmáticas possuem menores níveis de IgG e IgM, o que parece aumentar dos níveis de IgE, mães asmáticas possuem mais células de memória central, linfócitos T CD4+ produzem maiores quantidades de citocinas como IL-13 e IFN-g, células dendríticas de mães asmáticas possuem maior expressão das moléculas co-estimulatórias, assim como seus RNs possuem maior expressão de CD80. Células de mães asmáticas produzem níveis menores de IL-10, o colostro de mães atópicas não possui diferenças entre os parâmetros aqui estudados. O aleitamento materno deve ser indicado para mães asmáticas e seus filhos.

Abstract in English
Asthma has been presenting higher prevalence rates worldwide. The objective of this work is to evaluate the presence of cellular elements and humoral indicative in blood and colostrums of healthy and asthmatic mothers and in cord umbilical blood of their newborn (NB). Lower production of IgG from asthmatic mothers was observed. Dendritic cells of asthmatic mothers have higher CD80 and CD86 expression. Asthmatic mothers have more central memory cells. TCD4+ lymphocyte of asthmatic mothers produce higher levels of IFN-g. CD3+ and CD4+ cells of asthmatic mothers produce higher quantity of IL-13. Healthy mothers produce higher quantity of IL-10. We conclude that asthmatic mothers have lower levels of IgG and IgM, and this seems to raise the IgE levels, asthmatic mothers have more central memory cells, CD4+ T lymphocyte and produce higher quantities of cytokines such as Il-13 and IFN-g. Dendritic cells of asthmatic mothers have higher expression of costimulatory molecules, as well as their NBs have higher expression CD80. Cells of asthmatic mothers produce lower levels of IL-10, the colostrums of atopic mothers does not have differences in the parameters here studied. The maternal breastfeeding must be indicated for asthmatic mothers and their of spring.
