We analyzed the immunomodulatory effect of melatonin on acute allograft rejection. Cardiac grafts were transplanted from LBNF<jats:sub>1<\/jats:sub> to LEW rats and anastomosed to the abdominal great vessels. The effect of low\u2010dose (LD; 20\u2003mg\/kg\/day) and high\u2010dose (HD; 200\u2003mg\/kg\/day) melatonin treatment in recipients compared with untreated controls was investigated. HD melatonin therapy abrogated acute rejection, significantly prolonging allograft survival (mean survival: 12.3\u2003\u00b1\u20031\u2003days S.D., n\u2003=\u20038, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.0001) compared with untreated controls, which rapidly reject the transplant (6.3\u2003\u00b1\u20031\u2003days n\u2003=\u200312). LD therapy did not extend survival significantly (7.3\u2003\u00b1\u20031.1\u2003days, n\u2003=\u200312). Allospecific IgM showed a significant decrease in animals receiving HD therapy versus untreated recipients at days 10 and 14 post\u2010transplantation (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.01), whereas in the LD group at day 10, a significant increase in allospecific IgM (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.01) over the HD cohort was demonstrated. HD treatment markedly reduced lymphocyte proliferative capacity compared with controls and the LD group. HD melatonin treatment abrogated acute allograft rejection and significantly prolonged graft survival. Our results suggest an involvement of melatonin in humoral and cellular immune pathways following perfused organ transplantation. These findings may indicate a novel therapeutic approach, based on modulation of the neuroendocrine\/immune axis through melatonin as a possible future immunosuppressant in organ transplantation.<\/jats:p>","DOI":"10.1111\/j.1600-079x.2004.00133.x","type":"journal-article","created":{"date-parts":[[2004,7,2]],"date-time":"2004-07-02T06:11:53Z","timestamp":1088748713000},"page":"36-41","source":"Crossref","is-referenced-by-count":37,"title":["Melatonin in vivo prolongs cardiac allograft survival in rats"],"prefix":"10.1111","volume":"37","author":[{"given":"Florian J.","family":"Jung","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luc","family":"H\u00e4rter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilhan","family":"Inci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Didier","family":"Schneiter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Didier","family":"Lardinois","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marius","family":"Keel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walter","family":"Weder","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephan","family":"Korom","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,4,8]]},"reference":[{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-079X.2003.02111.x"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.1210\/edrv-1-2-109"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s001090050297"},{"key":"e_1_2_13_5_2","first-page":"57","article-title":"Melatonin: a potent endogenous hydroxyl radical scavenger","volume":"1","author":"Tan DX","year":"1993","journal-title":"Endocr J"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0891-5849(99)00131-8"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1521-690X(03)00016-2"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.2174\/1568026023394335"},{"key":"e_1_2_13_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-5728(98)00179-9"},{"key":"e_1_2_13_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(01)03101-0"},{"key":"e_1_2_13_11_2","first-page":"405","volume-title":"Psychoneuroimmunology","author":"Maestroni GJM","year":"1981"},{"key":"e_1_2_13_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-079X.1993.tb00478.x"},{"key":"e_1_2_13_13_2","doi-asserted-by":"publisher","DOI":"10.1096\/fasebj.13.12.1547"},{"key":"e_1_2_13_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s007020170061"},{"key":"e_1_2_13_15_2","doi-asserted-by":"publisher","DOI":"10.3181\/00379727-218-44270"},{"key":"e_1_2_13_16_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1010968611716"},{"key":"e_1_2_13_17_2","first-page":"384","article-title":"Role of the pineal gland in immunity: II.
