Methods and ResultsFor the in vitro study, human aortic
endothelial cells (HAECs) were preincubated for 18
hours with the indicated amount of adiponectin, then exposed to tumor
necrosis factor-
(TNF-
) (10 U/mL) or vehicle for the times
indicated. The adhesion of human monocytic cell line THP-1 cells to
HAECs was determined by adhesion assay. The surface expression of
vascular cell adhesion molecule-1 (VCAM-1),
endothelial-leukocyte adhesion molecule-1 (E-selectin),
and intracellular adhesion molecule-1 (ICAM-1) was measured by cell
ELISA. Physiological concentrations of adiponectin
dose-dependently inhibited TNF-
induced THP-1 adhesion and
expression of VCAM-1, E-selectin, and ICAM-1 on HAECs. For the in vivo
study, the concentrations of adiponectin in human plasma were
determined by a sandwich ELISA system that we recently developed.
Plasma adiponectin concentrations were significantly lower in patients
with coronary artery disease than those in age- and body mass
indexadjusted control subjects.
ConclusionsThese observations suggest that adiponectin modulates endothelial inflammatory response and that the measurement of plasma adiponectin levels may be helpful in assessment of CAD risk.

(TNF-
), and
plasminogen activator inhibitor
type 1, which may contribute to the development of
cardiovascular diseases.4 5 6 7 TNF-
overproduction in adipose tissue is a possible cause not only
of the development of insulin resistance8 but also of the
development of atherosclerosis through an inflammatory
process in obese subjects. However, the molecular basis for the link
between obesity and vascular disease has not been fully clarified. From
an extensive search of the human adipose tissue cDNA library, we
isolated an adipocyte-specific cDNA, apM1.4 9 The cDNA
encoded a 244-amino-acid protein homologous to collagen VIII and X and
complement factor C1q. Adiponectin, the gene product of apM1, was
found to be a secretory protein abundant in human
plasma.10 Plasma adiponectin level was decreased in
obesity,10 suggesting that dysregulation of adiponectin
may be relevant to obesity-linked disorders. Although adiponectin is
the most abundant gene product in adipose tissue9 and
accounts for 0.01% of total plasma protein,10 its
physiological functions have not been
elucidated.
At the early stages of atherosclerosis,
endothelial cell activation by various inflammatory
stimuli, including TNF-
, results in the synthesis of adhesion
molecules and increases the adherence of monocytes.11 This
monocyte adhesion to the arterial
endothelium is considered crucial for the development
of vascular diseases.11 We hypothesized that circulating
adiponectin might modulate vascular wall functions like other
adipocyte-derived secretory proteins.
In this study, we investigated the propositions that
physiological concentrations of adiponectin
suppressed TNF-
mediated expression of adhesion molecules in human
aortic endothelial cells (HAECs) and that plasma
adiponectin levels were markedly low in patients with coronary
artery disease (CAD).

(R&D systems) at a final
concentration of 10 U/mL or vehicle for the times indicated. Human
recombinant adiponectin was prepared as previously
described.10
Adhesion Assay
The adhesion of the THP-1 human monocytic cell line to HAECs was
determined as previously described.12 FITC-labeled THP-1
cells (5x105 cells/well) were incubated with
HAECs in 24-well plates for 10 minutes at 37°C. The plates were
sealed, inverted, and centrifuged (250g) for 5
minutes to separate nonadherent monocytes. Adherent cells were lysed
with 50 mmol/L Tris (pH 8.4)/0.1% SDS, and the
fluorescence was measured. Statistical significance was
determined by a paired t test.
Cell ELISA
HAECs were incubated at room temperature with antihuman
vascular cell adhesion molecule-1 (VCAM-1),
antiendothelial-leukocyte adhesion molecule-1
(E-selectin), or antiintracellular adhesion molecule-1 (ICAM-1)
monoclonal antibody (DAKO) at 1:1000 dilution in medium 199 containing
0.5% BSA for 1 hour and then with horseradish peroxidaseconjugated
goat anti-mouse IgG (Cappel) at 1:1000 dilution in the same
medium. Color formation with
o-phenylenediamine dihydrochloride was
measured at 492 nm.
Northern Blot Analysis
HAECs were pretreated with 50 µg/mL of adiponectin and exposed
to TNF-
for 4 hours. Total RNA (20 µg per lane) was extracted,
electrophoresed, and transferred to a nylon membrane. The membranes
were hybridized with human VCAM-1, E-selectin, or ICAM-1 cDNA probes
labeled with [
-32P]dCTP.
Measurement of Plasma Adiponectin Concentration
Consecutive CAD patients were recruited from inpatients admitted
to Osaka University Hospital. The criterion for CAD was a
75%
organic stenosis of
1 segment of a major coronary
artery confirmed by coronary angiogram. The control subjects
were selected from the inpatients of Osaka University Hospital and
matched with the CAD patients for age and body mass index (BMI). They
had no evidence of vascular diseases, including angina pectoris. All
subjects enrolled in this study were Japanese and gave written informed
consent. The Ethics Committee of Osaka University approved this
study.
The concentrations of adiponectin in human plasma were determined as described.10 The significance of the differences between the groups was determined by the Mann-Whitney test. Linear regression analysis was used to evaluate the relationship between the variables.

Induced Monocyte Adhesion and

treatment (10 U/mL for 6
hours) enhanced adhesion of THP-1 cells to HAECs by 2-fold (Figure 1A

dose-dependently suppressed by adiponectin treatment (Figure 1A

was not suppressed when adiponectin was added at the same time as THP-1
cells (data not shown), suggesting that adiponectin does not occupy the
binding sites of THP-1 cells on HAECs.

TNF-
treatment increased the surface expression of VCAM-1,
E-selectin, and ICAM-1 on HAECs by 2- to 5-fold (Figure 1
, B
through D). Dose-dependent suppression of TNF-
induced surface
expression of VCAM-1, E-selectin, and ICAM-1 was observed when HAECs
were pretreated with adiponectin (Figure 1
, B through D).
Adiponectin treatment alone did not lead to any significant changes in
the surface expression of these molecules in the absence of TNF-
(Figure 1
, B through D). The suppressive effects of adiponectin
on cell-surface expression of these adhesion molecules were accompanied
by changes in steady-state mRNA levels analyzed by Northern
blot (Figure 1
, B through D, inset).
Plasma Adiponectin Concentrations in Patients With CAD
Plasma adiponectin levels were significantly lower in patients
with CAD than in age- and BMI-adjusted control subjects both in men
(3.4±1.8 versus 7.4±3.5 µg/mL) (P<0.01) and in women
(4.3±1.5 versus 9.3±6.8 µg/mL) (P<0.05) (Figure 2
). Although atherogenic lipid profiles
were observed in the CAD group compared with the control (data not
shown), the decreased plasma adiponectin level may be another
coronary risk factor.

induced monocyte adhesion and adhesion molecule expression in
a dose-dependent manner in vitro. Atherosclerosis has
been regarded as an inflammatory disease. The initial atherosclerotic
lesion consists of monocytes/macrophages and T
lymphocytes.11 At this stage, adhesion molecules on
arterial endothelial cells are responsible
for the accumulation of these hemocytes. VCAM-1, E-selectin, and ICAM-1
have been detected in human atherosclerotic lesions.13 The
expression of adhesion molecule plays an important role in the
regulation of inflammatory reactions in various types of
cells.14 15 If the excess inflammatory response could be
neutralized by adiponectin, it might be possible to prevent the process
of atherogenesis. Our findings indicate that adiponectin acts as an
endogenous modulator of endothelial cell
function, although further investigation is needed to elucidate the
intracellular signals by which adiponectin suppresses adhesion
molecules. Recently, we developed an ELISA system to quantify the plasma adiponectin concentration.10 Paradoxically, the plasma adiponectin levels in obese subjects were significantly lower than those in nonobese subjects,10 although adiponectin is secreted only from adipose tissue. Because obesity is frequently accompanied by vascular diseases, we postulated that the dysregulation of adiponectin may be associated with vascular disease in obese subjects. In this study, plasma adiponectin levels were significantly lower in patients with CAD than in age- and BMI-adjusted control subjects. This finding suggests that the decreased plasma adiponectin level may relate to the development of CAD.
Adiponectin is an adipocyte-specific plasma protein, which acts as an endogenous regulator of endothelial cells in response to inflammatory stimuli. Our observations raise the possibility that the measurement of plasma adiponectin levels may be helpful in assessment of CAD risk.
