Prostaglandin E2 in Soluble Factor-Mediated Immune Suppression by First Trimester Decidual Cells

prostaglandin e2 in soluble factor-mediated immune suppression by first trimester decidual cells

several studies have shown that decidual tissue produces soluble factors which can mediate a variety of immunosuppressive activities. in order to assess whether prostaglandin e2 (pge2) was present in supernatants produced by explant culture of 10 human specimens of first trimester decidua. the effect of the supernatants from the two different series (with and without indomethacin treatment) of ...

Regulation of immune responses by prostaglandin E2.

PGE(2), an essential homeostatic factor, is also a key mediator of immunopathology in chronic infections and cancer. The impact of PGE(2) reflects the balance between its cyclooxygenase 2-regulated synthesis and 15-hydroxyprostaglandin dehydrogenase-driven degradation and the pattern of expression of PGE(2) receptors. PGE(2) enhances its own production but suppresses acute inflammatory mediator...

Prostaglandin E2 is a major soluble factor produced by stromal cells for preventing inflammatory cytokine production from dendritic cells.

Dendritic cells (DCs) are specialized antigen-presenting cells that play pivotal roles in initiating immune responses. However, DC maturation is usually strongly restricted by the stromal microenvironment, especially in non-lymphoid tissues, such as skin and mucosa. Although suppression of DC maturation by stromal cells has been well documented, the molecular basis of this suppression has not b...

Immunopathological Aspects of Decidual Tissues in Women with First-Trimester Recurrent Spontaneous Abortion

Background/objective: Studies of the decidual leukocyte populations in women suffering from spontaneous early pregnancy loss may provide insight into immunpathological aspects and even cast light on the etiology of recurrent spontaneous abortion.Methods: In order to clarify the immunological role of endometrial leukocytes in repetitive abortion of unknown etiology, a comparative analysis of phe...
