Abstract

Although human decidual lymphocytes have been widely studied, their function and possible interaction with trophoblast are still unclear. Here we show that whereas human early (EDL) and term (TDL) decidual lymphocytes were unable to kill human trophoblast by necrosis (assessed by the 51Cr-release assay) or apoptosis (DNA fragment assay), TDL but not EDL decreased trophoblast adhesion to a plastic substrate as determined by a [3H]thymidine assay. This effect, however, was not selective for trophoblast, as TDL also decreased the adhesion to plastic of human decidual stromal cells and HeLa cells. Our results suggest that TDL may play a role in placental detachment during parturition by decreasing trophoblast or decidual stromal cell adhesion.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
