OBJECTIVE Increased production of prostaglandins is associated with parturition. The production of interleukin-1 is increased in preterm labor occurring in the setting of infection. Interleukin-1 receptor antagonist prevents the effects of interleukin-1. Interleukin-4 and transforming growth factor-beta inhibit the production of prostaglandin E2 by monocytes and amnion cells, respectively. In addition, these cytokines enhance the production of interleukin-1 receptor antagonist by monocytes. We investigated whether the production of prostaglandin E2 and interleukin-1 receptor antagonist by decidual cells is modulated by interleukin-4 and transforming growth factor-beta 1. METHODS Human decidual cells in monolayer culture were treated for 44 hours with interleukin-4 (1 to 100 ng/ml), transforming growth factor-beta 1 (1 to 10 ng/ml), the combination of these cytokines, or vehicle. Production of prostaglandin E2 and interleukin-1 receptor antagonist was measured by radioimmunoassay and enzyme-linked immunosorbent assay, respectively. The Wilcoxon signed-rank test was used. RESULTS Both interleukin-4 and transforming growth factor-beta 1 inhibited prostaglandin E2 production by decidual cells (p < 0.01). Decidual cells produced interleukin-1 receptor antagonist at a basal rate of 26.4 +/- 6.7 pg/micrograms protein per 44 hours (n = 13). Interleukin-4 stimulated the production of interleukin-1 receptor antagonist by decidual cells (p < 0.01). Transforming growth factor-beta 1 potentiated the stimulatory effect of interleukin-4 on decidual cell interleukin-1 receptor antagonist production (p < 0.05). CONCLUSIONS By suppressing the production of prostaglandin E2 and enhancing the production of interleukin-1 receptor antagonist by decidual cells, interleukin-4 and transforming growth factor-beta may have a role in inhibiting preterm labor in the setting of infection.

UI	MeSH Term	Description	Entries
D007375	Interleukin-1	A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D003656	Decidua	The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.	Deciduum,Deciduas

D015232	Dinoprostone	The most common and most biologically active of the mammalian prostaglandins. It exhibits most biological activities characteristic of prostaglandins and has been used extensively as an oxytocic agent. The compound also displays a protective effect on the intestinal mucosa.

D015847	Interleukin-4	A soluble factor produced by activated T-LYMPHOCYTES that induces the expression of MHC CLASS II GENES and FC RECEPTORS on B-LYMPHOCYTES and causes their proliferation and differentiation. It also acts on T-lymphocytes, MAST CELLS, and several other hematopoietic lineage cells.

D016212	Transforming Growth Factor beta	A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.
