Methods and ResultsWe
tested the effects of CRP on the production of the chemokines
monocyte chemoattractant protein-1 (MCP-1) and RANTES in
cultured human umbilical vein endothelial cells. The
secretion of chemokines was assessed by ELISA. Incubation with 100
µg/mL recombinant human CRP induced a 7-fold increase in MCP-1 but no
change in RANTES secretion. We showed that the effect of CRP on MCP-1
was present even at 5 µg/mL CRP, with stepwise increases as the
CRP concentration was increased to 10, 50, and 100 µg/mL. The effect
of CRP on MCP-1 induction was not influenced by aspirin (at
concentrations up to 1 mmol/L), but it was significantly inhibited
by 5 µmol/L simvastatin. The peroxisome
proliferator-activated receptor-
activators
fenofibrate (100 µmol/L) and Wy-14649 (100 µmol/L) almost
completely abolished the induction of MCP-1, but the peroxisome
proliferator-activated receptor-
activator
ciglitazone had only a moderate effect.
ConclusionsThese results further strengthen the role of CRP in the pathogenesis of vascular inflammation and, likely, atherosclerosis and provide a crucial insight into a novel mechanism of action of anti-atherosclerosis drugs such as simvastatin and fenofibrate.

Recombinant human CRP and highly purified CRP from human
serum were purchased from Calbiochem, and
interleukin-1ß (IL-1ß) was obtained from RandD Systems. All
reagents were endotoxin-free by limulus test (from
Sigma; sensitivity, 0.06 U/mL). Purity of CRP
preparations was also confirmed by SDS-PAGE (single band on silver
staining of overloaded gels). For inhibitory experiments,
HUVEC were pretreated with various peroxisome
proliferator-activated receptor (PPAR)-
agonists, including
troglitazone (Parke-Davis), ciglitazone
(Biomol),
15-deoxy-
12,14-prostaglandin
J2 (15d-PGJ2;
Calbiochem); the PPAR
agonists fenofibrate
and Wy 14649 (Sigma); the
hydroxymethylglutaryl coenzyme A antagonist
(statin) simvastatin; or vehicle (0.1% DMSO or PBS) at the
concentrations indicated. After 2 hours, the cells were incubated with
CRP or IL-1ß 10 ng/mL for 24 hours. Simvastatin prodrug
(Merck) was activated as previously
described.5
Analysis of Conditioned Medium
Experiments were performed in HUVEC that were
cultured in 12-well plates in medium CS-C with 10 mmol/L HEPES and
15% human serum (Sigma). Culture supernatants
were collected 6 to 24 hours after stimulation with either IL-1ß or
CRP at the concentration indicated. The secretion of MCP-1 and RANTES
was assessed by sandwich ELISA (Quantikine, by RandD Systems). All
determinations were performed in duplicate. Data are expressed as
mean±SD of 5 to 6 separate experiments. Cell viability was assessed by
Trypan blue exclusion.
Analysis of multiple paired data within the same experiments was performed with the nonparametric Friedman test and the Wilcoxon test (GB-STAT V6 software). P<0.05 (2-tailed) was considered significant.

Secretion of RANTES was not increased by incubation with CRP
100 µg/mL
(Figure
,
panel B). Similarly, incubation with IL-1ß 10 ng/mL did not induce
RANTES expression.
Modulation of CRP Effects by Statins and
PPAR Activators
The effects of pretreatment with
simvastatin and several PPAR activators on the
induction of MCP-1 are shown in the
Table
.
Simvastatin 5 µmol/L significantly reduced (
43% of
maximal response) the secretion of MCP-1 induced by CRP. Aspirin, even
at high concentrations (up to 1 mmol/L), did not inhibit the
effects of CRP. The PPAR
activators troglitazone and
ciglitazone had no significant effects at low concentrations, but they
did significantly inhibit MCP-1 secretion at a high concentration (200
µmol/L ciglitazone). However, 15d-PGJ2 10 µmol/L almost completely
abolished the induction of MCP-1 by CRP. The PPAR
activators fenofibrate (100 µmol/L) and Wy 14649 (100
µmol/L) completely inhibited the secretion of MCP-1, although a lower
concentration (10 µmol/L) of Wy 14649 had no effect.

|

CRP is strongly associated with the occurrence of new
cardiovascular events in patients with both
unstable6 and stable angina,
and it is an important risk factor for cardiac mortality in normal
subjects.7 The mechanism(s)
of this association are still unclear. Although CRP can merely be a
marker of an underlying inflammatory/atherosclerotic process, it is
possible that CRP may be directly involved in the pathogenesis of
atherosclerosis/inflammation.1 2 3
CRP can induce the expression of tissue factor by
monocytes,8 9 and
it is present in atherosclerotic plaques but not in the normal
vessel wall.10 CRP deposits
in early atherosclerotic lesions may precede the appearance of
monocytes.11 Recently, we
found that CRP, at concentrations
5 µg/mL, induces the expression
of the adhesion molecules intracellular adhesion molecule-1 (ICAM-1),
vascular cell adhesion molecule-1 (VCAM-1), and E-selectin in
human endothelial
cells.3 The present study
is the first to demonstrate a direct effect of CRP on the secretion of
a specific chemokine (MCP-1) from endothelial cells.
These effects are evident at CRP concentrations similar to those
observed in patients at an increased risk of new coronary
events12 13 and
are close in magnitude to those observed with the proinflammatory
cytokine IL-1ß. Chemokines, particularly MCP-1, play a key
role in the migration of monocytes and T-cells into the vessel wall and
in the evolution of
atherosclerosis.14 15
Interestingly, neither CRP nor IL-1ß were able to induce
RANTES expression by endothelial cells. In a previous
study, no RANTES was produced after stimulating HUVEC with IL-1ß;
RANTES production was only induced by cotreatment with
interferon-
.16
Epidemiological studies have suggested an interaction between CRP and statins17 and aspirin treatment.7 18 Statins may reduce serum CRP levels17 and mortality in patients with low cholesterol levels but high CRP concentrations. Furthermore, statins can inhibit the expression of MCP-1 induced by IL-1 in endothelial cells and monocytes.19 In the present study, treatment with simvastatin partially inhibited the induction of MCP-1 by CRP on endothelial cells.
PPAR activators may reduce the proinflammatory
effects of cytokines on vascular cells and may have beneficial
effects on the progression of atherosclerosis in animal
models.20 21 22 23
Although in a previous study low concentrations of troglitazone (10
µmol/L) inhibited tumor necrosis factor-
induced MCP-1 expression
in endothelial
cells,24 in the present
study, thiazoledinediones had significant effects only at a high
concentration; this concentration was much higher than their affinity
for PPAR
, although 15d-PGJ2 had significant effects at
concentrations close to its KD for
PPAR
(2.5 µmol/L). However, the inhibitory effects of
15d-PGJ2 may be also due to its inhibition of nuclear factor-
B by
PPAR
-independent
mechanisms.25 PPAR
activators, such as fenofibrate and Wy 14649, almost
completely blocked the induction of MCP-1 by CRP. These
anti-inflammatory effects of PPAR
activators may be
explained, at least in part, by their inhibition of the nuclear
factor-
B and activator protein-1
pathways.26
In conclusion, our study demonstrates that CRP can induce the production of MCP-1 by endothelial cells. These effects can be modulated by pharmacological interventions, particularly simvastatin and fenofibrate. Our findings support the hypothesis of a direct role of CRP in the pathogenesis of inflammation/atherosclerosis and open the way to new pharmacological strategies for its treatment.
