The elevation in blood pressure in response to angiotensin II was virtually eliminated by AV3V lesions, as was activation of circulating T cells and the vascular infiltration of leukocytes. In contrast, AV3V lesioning did not prevent the hypertension and T-cell activation caused by the peripheral acting agonist norepinephrine. To determine whether T-cell activation and vascular inflammation are attributable to central influences or are mediated by blood pressure elevation, we administered hydralazine (250 mg\/L) in the drinking water. Hydralazine prevented the hypertension and abrogated the increase in circulating activated T cells and vascular infiltration of leukocytes caused by angiotensin II.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>\n                        <jats:underline>Conclusions<\/jats:underline>\n                        :\n                      <\/jats:italic>\n                    <\/jats:bold>\n                    We conclude that the central and pressor effects of angiotensin II are critical for T-cell activation and development of vascular inflammation. These findings also support a feed-forward mechanism in which modest degrees of blood pressure elevation lead to T-cell activation, which in turn promotes inflammation and further raises blood pressure, leading to severe hypertension.\n                  <\/jats:p>","DOI":"10.1161\/circresaha.110.217299","type":"journal-article","created":{"date-parts":[[2010,6,17]],"date-time":"2010-06-17T22:53:26Z","timestamp":1276815206000},"page":"263-270","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":298,"title":["Central and Peripheral Mechanisms of T-Lymphocyte Activation and Vascular Inflammation Produced by Angiotensin II\u2013Induced Hypertension"],"prefix":"10.1161","volume":"107","author":[{"given":"Paul J.","family":"Marvar","sequence":"first","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salim R.","family":"Thabet","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz J.","family":"Guzik","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heinrich E.","family":"Lob","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louise A.","family":"McCann","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Connie","family":"Weyand","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank J.","family":"Gordon","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David G.","family":"Harrison","sequence":"additional","affiliation":[{"name":"From the Division of Cardiology (P.J.M., S.R.T., H.E.L., L.A.M., D.G.H.), Department of Pharmacology (F.J.G.), and Lowance Center for Immunology (C.W.), Emory University School of Medicine, Atlanta, Ga; Atlanta Veterans Administration Hospital (D.G.H.), Decatur, Ga; and Department of Medicine, Jagiellonian University School of Medicine (T.J.G.), Cracow, Poland."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","first-page":"xiii","volume":"940","year":"2001","unstructured":"Chapleau MW, Abboud FM.
