“…Similarly, expression of CD64 on neutrophils and CD86 on monocytes was not correlated with phagocytic activity. Levels were comparable between preterm and term infants, as previously described for CD64 (35,39), although decreased CD86 has been reported in preterm neonates (37). These results are perhaps not surprising, given that all preterm infants included in this study were healthy and had not been exposed to chorioamnionitis in utero.…”

“…Although this is the focus of much of the investigation into HLA-DR expression, this is the first study to correlate expression with phagocytosis. Of note, although expression levels were significantly lower in preterm infants, as previously described (36,37), there was no correlation of expression with reduced phagocytosis, suggesting that the prognostic utility of HLA-DR expression is independent of phagocytosis functionality. The difference in HLA-DR expression and any effect on phagocytosis may be transient, as others have reported equivalent expression levels between preterm and term infants up to 7-9 d of age (38).…”

“…Os monócitos, ainda, sofrem diferenciação nos tecidos, onde se tornam macrófagos mononucleares ou células dendríticas (Pérez et al, 2010;Lewis e Wilson, 2011).…”

“…Embora monócitos clássicos pareçam ser menos eficientes no processo de apresentação antigênica, eles exibem um papel essencial no desenvolvimento da imunidade inata (Pérez et al, 2010 (Unanue, 2002). Essas células interagem com linfócitos T naïve formando a "sinapse imunológica", o que leva à maturação e a geração de células T efetoras totalmente ativadas (Pérez et al, 2010 (Angelone et al, 2006;Beutler, 2005).…”
