Prostaglandin E2 Receptors, EP2 and EP4, Differentially Modulate TNF-¦Á and IL-6 Production Induced by Lipopolysaccharide in Mouse Peritoneal Neutrophils ¡î

Preparation of peritoneal neutrophils. Mice were injected intraperitoneally
with 2 ml of 5% casein in sterile saline and were killed
by cervical dislocation 5¨C6 h after injection. The lavage fluids were
collected in a syringe, and exudated peritoneal cells were precipitated
by centrifugation. Neutrophils in peritoneal cells were purified
by Percoll stepwise density gradient (1.090 and 1.070 g/ml) centrifugation
(600g for 20 min at 4¡ãC). The purity of neutrophils was
greater than 95% as determined by staining with May¨CGrunwald¨C
Giemsa. Neutrophils were suspended in RPMI 1640 medium
containing 10% heat-inactivated fetal bovine serum, 150 mM
2-mercaptoethanol and 100 mM sodium pyruvate.

Measurement of cytokine production. Neutrophils (1 3 106 cells/
ml) were incubated with or without 100 ng/ml LPS for the indicated
time at 37¡ãC in 5% CO2. After incubation, each culture was centrifuged
at 300g for 5 min at 4¡ãC to remove the cells. The amounts of
TNF-a and IL-6 in the supernatant were assayed using the respective
ELISA kits according to the manufacturer¡¯s instructions.

Effect of PGE2 on LPS-Stimulated TNF-a and IL-6
Production in Mouse Peritoneal Neutrophils
LPS treatment (100 ng/ml) induced the production of
TNF-a and IL-6 in mouse peritoneal neutrophils (Fig.
3). TNF-a production rapidly increased and then decreased
to the basal level by 12 h. The maximum level
was obtained at 2 h after LPS stimulation. However,
IL-6 production increased gradually and reached a plateau
level at 8 h after LPS stimulation. Simultaneous
addition of PGE2 with LPS suppressed the TNF-a production
and enhanced the IL-6 production significantly
(Fig. 3). However, the PGE2 effects in the absence of
LPS were relatively small.
Dibutyryl cAMP (1 mM) suppressed the TNF-a production
at 2 h and enhanced the IL-6 production at 4 hr
after the LPS stimulation in peritoneal neutrophils
(Table I).
It was reported that endogenous PG synthesis was
induced by LPS treatment through COX-2 induction in
human neutrophils [16, 17]. However, in mouse peritoneal
neutrophils pretreatment with indomethacin (1
mM), a nonselective COX inhibitor, induced no changes
in the LPS-stimulated production of TNF-a and IL-6
(data not shown).

For peritoneal neutrophils, cells were isolated from the peritoneal cavity after 4 hr of thioglycollate injection and cultured for 18 hr in the presence or absence of 10 ng/ml IL-10. Then, nonadherent cells were harvested and used for further experiments. These cells were >90% positive for Gr-1 as determined by flow cytometry. In the case of more strict experiments, the cells were further enriched by magnetic cell sorting (MACS, Miltenyi Biotec) using biotin-conjugated anti-Gr-1 antibody and streptavidin-microbeads.
