Expression of CD44 and IL-10 in normotensive and preeclamptic placental tissue.

CD44 was found to be an essential molecule in the regulation of vascular permeability, inflammatory response, activation of the cells, cell-to-cell interaction, and the signaling pathways to which they are associated. Since IL-10 regulates appropriate pregnancy outcomes and contributes to the balance of anti-inflammatory signals via both paracrine and autocrine regulators of trophoblast activity, we proposed that it might be a key to elucidate the etiology of preeclampsia with CD44 receptor.
