The effect of maternal infection on cognitive development and hippocampus neuronal apoptosis, proliferation and differentiation in the neonatal rats.
Many epidemiological reports stated a strong association between maternal infection and development of cerebral palsy, which is a major cause of cognitive impairment. The pathophysiological mechanism of intrauterine inflammation is complex. Recently, it was demonstrated that inflammation has a modulating effect on adult neurogenesis. ⋯ On P28, there was no significant difference of cell survival and differentiation in two groups. These results suggest that variation in ERK activity and subsequent expression of its downstream targets, including CREB and BDNF might contribute, at least partially, to modulation of inflammation related cell proliferation, survival and differentiation. Maternal infection increased hippocampal neuronal apoptosis and affected cell proliferation and differentiation in neonatal rats, which may be regarded as an etiological factor in cognitive development impairment.
