Cerebral palsy (CP) is a major neurodevelopmental disability in childhood. An association between intrauterine infection and CP has been reported. We examined the relationship between inflammatory mediators in cord serum and CP in term and preterm children. Regional multicenter study was conducted on 19 CP children and 19 gestation-matched paired controls. CP children (n = 27) were further compared with controls of similar gestation at birth (n = 25). Serum levels of 78 protein mediators were analyzed. Eleven analytes correlated with the length of gestation both in cases and controls. In paired analysis, B-lymphocyte chemoattractant, ciliary neurotrophic factor, epidermal growth factor, interleukin (IL)-5, IL-12, IL-13, IL-15, macrophage migration inhibitory factor, monocyte chemoattractant protein-3, monokine induced by interferon gamma, and tumor necrosis factor-related apoptosis-inducing ligand were higher in children with CP (p < or = 0.05). Preterm infants with CP showed higher epidermal growth factor and lower levels of granulocyte-macrophage colony-stimulating factor, IL-2, macrophage-derived chemokine, and pulmonary and activation-regulated chemokine than their paired controls. Inflammatory mediators and growth factors serve as a footprint of the fetal response to an insult manifesting after birth as a permanent brain damage. The cytokine patterns at birth differ between premature and term infants who develop CP.

Interleukin-6 (IL-6) is produced by neurons, astrocytes, and microglia, and elevated levels of IL-6 within the CNS have been documented in multiple neurological disorders including Alzheimer's disease, stroke, epilepsy, attention deficit disorder, cerebral palsy, and multiple sclerosis. Here, we sought to understand how IL-6 regulates microglial signal transduction and their immune properties. Using highly enriched cultures of neonatal murine microglia we show that IL-6 alone has direct effects on microglia as it activates STAT3 and extracellular signal-regulated kinase pathways in a time- and dose-dependent fashion and it enhances interferon-gamma (IFNgamma)-stimulated IL-12 secretion. However, other immune properties were only weakly modulated by IL-6 when administered without the soluble IL-6 receptor (sIL-6R). For instance, IFNgamma-induced expression of the co-stimulatory molecule, CD40 was dependent on sIL-6R administration. IL-6 with or without sIL-6R did not affect major histocompatability complex class II expression. In granulocyte-macrophage colony-stimulating factor (GMCSF)-induced dendritic cell-like microglia, IL-6/sIL-6R and IFNgamma stimulated an even greater increase in CD40 expression compared with primary microglia. Altogether, our results demonstrate that microglial responses to IL-6 are not simple in that the effects of IL-6 are context-dependent. In particular, the presence or absence of sIL-6R, IFNgamma or GMCSF will alter the type and amplitude of their response.
