Chorioamnionitis associates with altered HLA-DR and CD80 expression on monocytes. a Comparison of monocyte frequencies between healthy and chorioamnionitis-exposed preterm neonates from D14 and W36. b PCA of the monocyte compartment including frequencies and expression levels of HLA-DR, CD80, CD86, and TLR4 on total CD14⁺ cells from healthy and chorioamnionitis- and preeclampsia-exposed preterm neonates. Proportions (c) and expression levels (d) of monocyte-associated HLA-DR, CD80, CD86, and TLR4 of healthy and ELBW (D14 and W36) preterm infants encountered with chorioamnionitis. Interleaved box and whisker plots show median as the central line, and error bars represent minimum to maximum values. The Mann-Whitney U test was used for comparison between healthy and chorioamnionitis-exposed group.
