Abstract
The interaction of natural killer and trophoblast cells underlies
maternal-fetal immune tolerance. The data on the participation of
endoglin (ENG, CD105), or its soluble form, in the regulation of
the communication of these cells are currently insufficient. In
this study, we have investigated the role of endoglin in the intercellular
interactions between natural killer cells and trophoblasts. Here,
we show that NK-92 cells and JEG-3 cells constitutively express
MICA/B, and CD105. In the presence of JEG-3 cells, the expression
of NKG2D, CD94, MICA/B, and CD105 by NK-92 cells was increased,
and the number of NK-92 cells expressing NKG2A, CD94, and MICA was
reduced. Antibodies against ENG and recombinant endoglin (rENG),
attenuated the trophoblasts’ influence and returned the phenotype of
the NK-92 cells to that of cells found in monoculture conditions.
The antibodies and rENG also increased the expression of pSMAD2/3
by NK cells in both monoculture and co-culture conditions. The antibodies
increased the trophoblasts’ sensitivity to the cytotoxic effect
of NK cells. In general, our findings indicate a significant role
of endoglin in the intercellular communication between NK cells
and trophoblasts. We also speculate that endoglin forms a complex
with TGFβ, which aids in TGFβ trafficking between these cells.
