    ABSTRACT: While OX42(+) microglia/macrophages have been considered as a scavenger in the brain, NG2(+) cells are generally considered as oligodendrocyte progenitor cells or function-unknown glial cells. Recent evidence showed that under some pathological conditions, certain cells have become positive for both anti-NG2 and anti-OX42 antibodies. Our results suggested that some OX42(+) microglia or macrophages were induced to express NG2 proteins 3 and 5 days later after focal injection of lipopolysaccharide into the brain cortex of Sprague-Dawley rats. In consideration of the induction of NG2 expression may associate with gaining or losing functions of microglia/macrophages, we further showed that, while OX42(+) or ED1(+) microglia/macrophages presented active phagocytic function, NG2(+) /OX42(+) cells failed to engulf latex beads. The induced expression of NG2 protein may possibly indicate the functional diversity of activated microglia/macrophages in the brain.
