Seven Japanese Herbals Prolonged Cardiac Allograft Survival. Transplant Proc 2018; 50:2789-2793. [PMID: 30401398 DOI: 10.1016/j.transproceed.2018.04.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 03/16/2018] [Accepted: 04/06/2018] [Indexed: 01/24/2023]
Abstract
Japanese herbal medicines have long been used as alternative therapy because of their immunomodulatory effects. In recent years, use herbal medicines is rapidly increasing worldwide. In this study, we investigated the effect of 17 components of traditional Japanese herbal medicines on alloimmune responses in a murine model of cardiac allograft transplantation. Fully vascularized heterotopic hearts from C57BL/6 donors were transplanted into CBA mice by using microsurgical techniques. Artemisiae capillaris herba (Inchinko) was given to CBA recipients at a dosage of 1 g/kg/day from the day of transplantation until 7 days afterward. The other 16 components were given at a dosage of 2 g/kg/day for the same time period. Naïve CBA mice rejected C57BL/6 cardiac grafts acutely (median survival time [MST] of 7 days). CBA transplant recipients given 2 g/kg/day of Glycyrrhizae radix (Kanzou), Poria sclerotium (Bukuryo), Pinellia tuber (Hange), Cnidii rhizome (Senkyu), Paeoniae radix (Shakuyaku), and Scutellariae radix (Ogon) had prolonged C57BL/6 allograft survival significantly (MSTs were 18, 18, 17, 14, 12, and 12 days, respectively). Moreover, CBA transplant recipients given 1g/kg/day of Artemisiae capillaris herba had prolonged C57BL/6 allograft survival (MST >100 days); however, none of other 10 components prolonged allograft survival. In conclusion, administration of 7 components of traditional Japanese herbal medicines might induce prolongation of fully major histocompatibility complex-mismatched cardiac allografts.

Administration of donor splenocytes via the respiratory tract generates CD8α + regulatory dendritic cells and induces hyporesponsiveness to fully allogeneic cardiac grafts. Transpl Immunol 2018; 50:60-67. [PMID: 29990543 DOI: 10.1016/j.trim.2018.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2018] [Revised: 06/30/2018] [Accepted: 07/06/2018] [Indexed: 11/17/2022]
Abstract
BACKGROUND We previously showed that pretreatment with intratracheal delivery (ITD) of alloantigen induced prolonged cardiac allograft survival and generated regulatory T cells (Tregs) in mice. In this study, we examined the role of splenic dendritic cells (DCs) in the ITD model. METHODS CBA mice were treated with ITD from C57BL/10 splenocytes and 7 days later received transplantation of C57BL/10 hearts. In adoptive transfer studies, splenic DCs from ITD-treated mice were transferred into naïve CBA recipients that received C57BL/10 hearts immediately after the transfer. In addition, to determine the role of splenic DCs isolated from ITD-treated mice, the cells were incubated under stimulation with lipopolysaccharide (LPS). RESULTS ITD-treated CBA recipients had markedly prolonged allograft survival (median survival time [MST], 67 days) while naïve recipients rejected allografts acutely (MST, 8 days). In adoptive transfer studies, CBA recipients of the transfer of splenic DCs from ITD-treated mice had prolonged allograft survival (MST, 85 days), while CBA recipients of the transfer of splenic DCs from naïve mice did not have prolonged allograft survival (MST, 8 days). In another transfer study, CBA recipients of the transfer of splenic CD8α+ DCs from ITD-treated mice had prolonged allograft survival (MST, 79 days), while those receiving splenic CD8α- DCs from ITD-treated mice did not have prolonged allograft survival (MST, 8 days). In vitro studies showed that ITD-treated splenic DCs produced more IL-10 and less IL-12 than naïve splenic DCs under stimulation with LPS. CONCLUSIONS ITD pretreatment induces regulatory DCs, which produce high amounts of IL-10 resulting in the prolongation of graft survival in our model.

Abstract
Rikkunshito (TJ-43), an eight-component traditional Japanese herbal medicine, has been used in clinics for gastritis, vomiting, and appetite loss. We investigated the effects of TJ-43 on the amelioration of appetite loss in the surgical-exposed model of murine cardiac allograft transplantation. CBA mice underwent transplantation of a CBA (syngeneic group) or C57BL/6 heart (allogeneic group) and received oral administration of 2 g/kg/d of TJ-43 from the day of transplantation until 7 days afterward. The amount of food intake (FI) and weight change after operation were recorded from 1 to 28 postoperative days. The allogeneic group had less average amounts of FI for 1 week compared with the syngeneic group (FI was 1.90 ± 0.43 g and 2.66 ± 0.46 g, respectively). Average FIs between the syngeneic and allogeneic groups with TJ-43 for 1 week were 2.36 ± 0.44 g and 2.30 ± 0.13 g, respectively, and those with distilled water were 2.66 ± 0.46 g and 1.90 ± 0.43 g, respectively, suggesting that exposure with TJ-43 tended to ameliorate the reduction of FI. Similarly, the effect on the amelioration of average FI in syngeneic and allogeneic groups exposed for 2 weeks was confirmed. However, exposure to with TJ-43 had no effects on FI after 4 weeks. TJ-43 could prevent reduction of average FI induced by the surgical-exposed model of murine cardiac allograft transplantation.

Abstract
Shigyakusan (also known as Tsumura Japan [TJ]-35) is composed of peony, bitter orange, licorice, and Bupleuri radix is used for cholecystitis and gastritis as an anti-inflammatory agent. We investigated the effect of TJ-35 on alloimmune response in a murine heart transplantation model. CBA mice that underwent transplantation of a C57BL/6 (B6) heart were assigned to four groups: no treatment, TJ-35-exposed, each component-exposed, or each component missing-exposed. The four groups above each received oral administration of TJ-35, each component, or TJ-35 with each component missing from the day of transplantation until 7 days, respectively. Untreated CBA recipients rejected B6 cardiac grafts acutely (median survival time [MST], 7 days). TJ-35-exposed CBA recipients had significantly prolonged B6 allograft survival (MST, 20.5 days). However, MSTs of CBA recipients that had been administered each component and TJ-35 with each component missing did not reach that of TJ-35-exposed recipients. Adoptive transfer of CD4+ splenocytes from TJ-35-exposed primary allograft recipients resulted in significant prolonged allograft survival in naïve secondary recipients (MST, 63 days). Flow cytometry studies showed that the percentage of CD4+CD25+Foxp3+ cell population was increased in TJ-35-exposed CBA recipients. In conclusion, TJ-35-induced prolongation of fully allogeneic cardiac allografts and may generate regulatory CD4+CD25+Foxp3+ cells in our model. The effect seemed to require all components of TJ-35.

Abstract
Exercise therapy has been associated with improvement in functional capacity and quality of life. The role of exercise therapy in heart transplant recipients is of great interest for the transplant society, although concerning the effect of exercise therapy, there is little knowledge at present. We analyzed the effects of exercise on alloimmune responses in murine cardiac allograft transplantation. CBA mice (H2k) underwent transplantation of C57Bl/6 (H2b) hearts and exercised on a treadmill. Untreated CBA recipients rejected C57Bl/6 cardiac grafts acutely (median survival time [MST], 7 days). CBA recipients treated with treadmill for 1 week after transplantation, and for 1 week both before and after transplantation prolonged allograft survivals (MSTs, 35 and 18 days, respectively). However, treadmill exercise recipients for 1 week before transplantation were not effective to allograft survival (MST, 8 days). Adoptive transfer of whole splenocytes and CD4+ cells from treadmill exercise recipients significantly prolonged allograft survival in naive secondary recipients (MSTs, 30 and 52 days, respectively), suggesting that regulatory cells was generated after treadmill exercise. Moreover, flow cytometry studies showed that CD4+CD25+Foxp3+ cell population increased in treadmill exercise recipients. Therefore, postoperative but not pre-operative exercise could induce prolongation of survival of fully allogeneic cardiac allografts and generate CD4+CD25+Foxp3+ regulatory T cells.

Abstract
Herbal medicines have been used for over 3,000 years in Asian as alternative therapy for their variety effects and have recently become popular in Europe and the United States. In the last 30 years, Japanese herbal medicines were widely used for treatment of diseases after been recognized officially by Japanese government. In this study, we investigated the effect of 34 kinds of traditional Japanese herbal medicines on alloimmune responses in a murine model of cardiac allograft transplantation. CBA mice (H2(k)) underwent transplantation of a C57BL/6 (H2(b)) heart and received oral administration of 2 g/kg/d of the 34 kinds of herbal medicines from the day of transplantation until 7 days afterward. Naïve CBA mice rejected B6 cardiac grafts acutely (median survival time [MST], 7 days). CBA transplant recipients given 2 g/kg/d of Sairei-to (TJ-114) and Tokishakuyaku-san (TJ-23) had prolonged C57BL/6 allograft survival indefinitely (both MSTs > 100 days). Moreover, CBA transplant recipients given Seisinrensiin (TJ-111), Tokishigyakukagoshuyushokyoto (TJ-38), Rikkunshito (TJ-43), Maobushisaishinto (TJ-127), Ninjin-yoei-to (TJ-108), Ryokan-kyomi-shinge-nin-to (TJ-119), Inchingorei-san (TJ-117), Hochuekkito (TJ-41), Kihi-to (TJ-65), and Sinbu-to (TJ-30) had also prolonged C57BL/6 allograft survival significantly (MSTs of 28, 22, 16, 14, 14, 13, 12, 9.5, 9 and 9 days, respectively). However, none of other 22 kinds of herbal medicines could prolong the allograft survival. Furthermore, oral administration of 2 g/kg/d of Daikenchuto (TJ-100) induced sudden death (within 1 minute) in CBA mice. In conclusion, 12 kinds of Japanese herbal medicines prolonged allograft survival and one showed toxic effect in mice.

Abstract
Background Herbal medicines have unique odors, and the act of smelling may have modulatory effects on the immune system. We investigated the effect of olfactory exposure to Tokishakuyaku-san (TJ-23), a Japanese herbal medicine, on alloimmune responses in a murine model of cardiac allograft transplantation. Methods Naïve or olfactory-dysfunctional CBA mice underwent transplantation of a C57BL/6 heart and were exposed to the odor of TJ-23 until rejection. Some naïve CBA recipients of an allograft were given olfactory exposure to Sairei-to (TJ-114), trimethylthiazoline (TMT), individual components of TJ-23, or a TJ-23 preparation lacking one component. Adoptive transfer studies were performed to determine whether regulatory cells were generated. Results Untreated CBA mice rejected their C57BL/6 allografts acutely, as did olfactory-dysfunctional CBA mice exposed to the odor of TJ-23. CBA recipients of a C57BL/6 heart given olfactory exposure to TJ-23 had significantly prolonged allograft survival, whereas those exposed to the odor of TJ-114, TMT, one component of TJ-23, or TJ-23 lacking a component did not. Secondary allograft recipients that were given, at 30 days after transplantation, either whole splenocytes, CD4+ cells, or CD4+CD25+ cells from primary recipients exposed to the odor of TJ-23 had indefinitely prolonged allograft survival. Conclusions Prolonged survival of cardiac allografts and generation of regulatory cells was associated with exposure to the odor of TJ-23 in our model. The olfactory area of the brain may have a role in the modulation of immune responses.

Abstract
BACKGROUND The co-inhibitory receptor B and T lymphocyte attenuator (BTLA) has been implicated in the regulation of autoimmunity and may potentially play an important role in allograft tolerance. This study investigated the effect of an agonistic anti-BTLA mAb (3C10) in the fully major histocompatibility complex-mismatched murine cardiac transplantation. METHODS CBA mice underwent transplantation of C57BL/6 hearts and received one dose of 3C10 on the day of transplantation (day 0) or four doses of 3C10 on day 0, 3, 6, and 9. Adoptive transfer studies were performed to determine whether regulatory cells were generated. Moreover, to confirm the requirement for regulatory T cell and Th-2 cytokines, anti-interleukin (IL)-2 receptor alpha antibody (PC-61) or anti-IL-10 antibody (JES-2A5) was administered to a 3C10-treated CBA recipient. RESULTS CBA mice treated with one and four doses of 3C10 prolonged allograft survival (median survival times [MSTs], 43 and >100 days, respectively). Secondary CBA recipients given whole splenocytes or CD4 cells from primary 3C10-treated CBA recipients had significantly prolonged survival of C57BL/6 hearts (MSTs, >100 in both). Also, flow cytometry studies showed an increased CD4CD25Foxp3 cell population in 3C10-treated mice. Additionally, IL-2 and interferon-γ production were suppressed in 3C10-treated mice, and IL-4 and IL-10 from 3C10-treated CBA mice increased. Moreover, 3C10 directly suppressed alloproliferation in a mixed leukocyte culture. However, administration of PC-61 or JES-2A5 clearly attenuated prolonged survival of 3C10-treated mice (MSTs, 15.5 and 13.5 days, respectively). CONCLUSION 3C10 could control acute rejection by its suppressive effect on alloreactive T cells and induction of IL-10-dependent regulatory CD4 T cells.

Abstract
In clinical practice, music has been used to decrease stress, heart rate, and blood pressure and to provide a distraction from disease symptoms. We investigated sound effects on alloimmune responses in murine heart transplantation. Naïve and eardrum-ruptured CBA/N (CBA, H2(K)) underwent transplantation of a C57BL/6 (B6, H2(b)) heart and were exposed to 1 of 3 types of music-opera (La Traviata), classical (Mozart), and New Age (Enya)-or 1 of 6 different single sound frequencies for 7 days. An adoptive transfer study was performed to determine whether regulatory cells were generated in allograft recipients. Cell-proliferation, cytokine, and flow cytometry assessments were also performed. CBA recipients of a B6 graft exposed to opera and classical music had significantly prolonged allograft survival (median survival times [MSTs], 26.5 and 20 days, respectively), whereas those exposed to 6 single sound frequencies and New Age did not (MSTs, 7, 8, 9, 8, 8, 8, and 11 days, respectively). Untreated and eardrum-ruptured CBA rejected B6 grafts acutely (MSTs, 7 and 8.5 days, respectively). Adoptive transfer of whole splenocytes, CD4(+) cells, and CD4(+)CD25(+) cells from opera-exposed primary recipients resulted in significantly prolonged allograft survival in naive secondary recipients (MSTs, 36, 68, and >50 days, respectively). Cell-proliferation, interleukin (IL)-2 and interferon-γ were suppressed in opera-exposed mice, whereas IL-4 and IL-10 from opera-exposed recipients were up-regulated. Flow cytometry studies showed an increased CD4(+)CD25(+)Foxp3(+) cell population in splenocytes from opera-exposed mice. In conclusion, exposure to some types of music may induce prolonged survival of fully allogeneic cardiac allografts and generate CD4(+)CD25(+)Foxp3(+) regulatory cells.

Abstract
We investigated Inchingorei-san (TJ-117), a 6-component Japanese herbal medicine, on alloimmune responses in murine cardiac allograft transplantation. CBA mice underwent transplantation of a C57BL/6 (B6) heart and received oral administration of TJ-117 or each component of TJ-117 from the day of transplantation until 7 days afterward. Naive CBA mice rejected B6 cardiac grafts acutely (median survival time (MST), 7 days). CBA recipients given 1 g/kg/day of TJ-117 had prolonged B6 allograft survival (MST, 37 days). Moreover, given 1 g/kg/day of Artemisiae Capillaris Herba (ACH), one component of TJ-117, indefinitely prolonged B6 allograft survival (MST, >100 days). However, other five components of TJ-117 were less effective than TJ-117 and ACH. Secondary CBA recipients given whole splenocytes, CD4+, and CD4+CD25+ cells from primary ACH-treated CBA recipients with B6 cardiac allografts 30 days after grafting had prolonged survival of B6 hearts (MSTs, 57, >100, and >100 days, resp.). Flow cytometry studies showed that the CD4+CD25+Foxp3+ regulatory cell population was increased in transplant recipients given ACH. Cell proliferation, interleukin-2, and interferon-γ were suppressed in ACH-treated mice, whereas interleukin-4 and interleukin-10 were upregulated. In conclusion, ACH, one component of TJ-117, as well as TJ-117 induced hyporesponsiveness to fully allogeneic cardiac allografts and may generate CD4+CD25+Foxp3+ regulatory cells.

Abstract
BACKGROUND Interactions between the immune response and brain functions such as olfactory, auditory, and visual sensations are likely. This study investigated the effect of sounds on alloimmune responses in a murine model of cardiac allograft transplantation. METHODS Naïve CBA mice (H2k) underwent transplantation of a C57BL/6 (B6, H2b) heart and were exposed to one of three types of music--opera (La Traviata), classical (Mozart), and New Age (Enya)--or one of six different single sound frequencies, for 7 days. Additionally, we prepared two groups of CBA recipients with tympanic membrane perforation exposed to opera for 7 days and CBA recipients exposed to opera for 7 days before transplantation (pre-treatment). An adoptive transfer study was performed to determine whether regulatory cells were generated in allograft recipients. Immunohistochemical, cell-proliferation, cytokine, and flow cytometry assessments were also performed. RESULTS CBA recipients of a B6 cardiac graft that were exposed to opera music and Mozart had significantly prolonged allograft survival (median survival times [MSTs], 26.5 and 20 days, respectively), whereas those exposed to a single sound frequency (100, 500, 1000, 5000, 10,000, or 20,000 Hz) or Enya did not (MSTs, 7.5, 8, 9, 8, 7.5, 8.5 and 11 days, respectively). Untreated, CBA mice with tympanic membrane perforations and CBA recipients exposed to opera for 7 days before transplantation (pre-treatment) rejected B6 cardiac grafts acutely (MSTs, 7, 8 and 8 days, respectively). Adoptive transfer of whole splenocytes, CD4+ cells, or CD4+CD25+ cells from opera-exposed primary allograft recipients resulted in significantly prolonged allograft survival in naive secondary recipients (MSTs, 36, 68, and > 100 days, respectively). Proliferation of splenocytes, interleukin (IL)-2 and interferon (IFN)-γ production was suppressed in opera-exposed mice, and production of IL-4 and IL-10 from opera-exposed transplant recipients increased compared to that from splenocytes of untreated recipients. Flow cytometry studies showed an increased CD4+CD25+ Forkhead box P3 (Foxp3)+ cell population in splenocytes from those mice. CONCLUSION Our findings indicate that exposure to opera music, such as La traviata, could affect such aspects of the peripheral immune response as generation of regulatory CD4+CD25+ cells and up-regulation of anti-inflammatory cytokines, resulting in prolonged allograft survival.

Abstract
Danazol, a derivative of testosterone, is useful for treatment of endometriosis as well as pretreatment for in vitro fertilization and embryo transfer, although its mechanisms of action are unclear. The aim of this study was to investigate the effect of danazol on alloimmune responses in murine heart transplantation. CBA male mice (H2(k) ) underwent transplantation of C57BL/6 male (H2(b) ) hearts and received a single dose of danazol (0.4, 1.2 or 4mg/kg/day) by intraperitoneal injection on the day of transplantation and for 6days thereafter. An adoptive transfer study was performed to determine whether regulatory cells were generated. The median survival time (MST) of allografts in danazol-treated (1.2 and 4mg/kg/day) mice was 28 and 63days, respectively, compared with 7days in untreated mice. Moreover, secondary CBA recipients given whole splenocytes or CD4(+) cells from primary danazol-treated (4mg/kg/day) CBA recipients 30days after transplantation had prolonged allograft survival (MSTs, 29 and 60days, respectively). Cell proliferation, interleukin (IL)-2 and interferon-γ were suppressed in danazol-treated mice, whereas IL-4 and IL-10 were up-regulated. Moreover, danazol directly suppressed allo-proliferation in a mixed leukocyte culture. Flow cytometry showed an increased CD4(+) CD25(+) Foxp3(+) cell population in splenocytes from danazol-treated mice. Danazol prolongs cardiac allograft survival and generates regulatory CD4(+) cells.

Depletion of alveolar macrophages abrogates prolongation of cardiac allograft survival induced by intratracheal delivery of alloantigen. Transplantation 2011; 91:413-24.

Abstract
BACKGROUND We previously showed that pretreatment with intratracheal delivery (ITD) of alloantigen induced prolonged cardiac allograft survival and generated regulatory cells in mice. In this study, we examined the role of alveolar macrophages (AM) in our ITD model. METHODS Some CBA mice were given ITD of C57BL/6 splenocytes and underwent transplantation of C57BL/6 hearts 7 days later. In others, AM were depleted with clodronate-loaded liposomes 3 days before ITD. In adoptive transfer studies, whole splenocytes were obtained from ITD-treated CBA mice and administered to naïve CBA secondary recipients, which were given C57BL/6 hearts immediately afterward. Interleukin-10 concentrations in bronchoalveolar lavage fluid were assessed by enzyme-linked immunosorbent assays. Immunohistologic and flow cytometric studies were performed after ITD. RESULTS C57BL/6 splenocytes given by ITD were ingested by AM in 2 days and undetectable in paratracheal lymph nodes or spleen tissue. CBA mice given ITD of C57BL/6 splenocytes had markedly prolonged allograft survival (median survival time [MST], 86 days), whereas naïve CBA mice rejected allografts acutely (MST, 8 days). AM-depleted, ITD-treated mice also rejected allografts (MST, 5.5 days). Naïve secondary recipients given adoptive transfer of splenocytes from ITD-treated mice had prolonged allograft survival (MST, >100 days), whereas secondary recipients given adoptive transfer of splenocytes from AM-depleted, ITD-treated mice rejected the grafts (MST, 15.5 days). Interleukin-10 expression in bronchoalveolar lavage fluid was down-regulated in AM-depleted mice compared with naïve mice. CONCLUSIONS AM have an important role in the induction of regulatory cells in our model of ITD of alloantigen.

Abstract
BACKGROUND Ursodeoxycholic acid (UDCA) has been used to treat patients with cholestatic and autoimmune liver diseases. Several studies have addressed whether UDCA can inhibit graft rejection in experimental and clinical transplantation, but the results have varied. We investigated the effect of UDCA and the mechanism of its effect on alloimmune responses in a murine model of cardiac transplantation. METHODS CBA mice underwent transplantation of a C57BL/10 heart and received a single dose of UDCA. Survival times of the allografts were recorded. An adoptive transfer study was conducted to determine whether regulatory cells were generated. The effects on graft survival of adding FK506 or cyclosporine A (CyA) to UDCA treatment were assessed. Histologic, cell proliferation, and cytokine assessments were performed. RESULTS CBA recipients given UDCA (25 mg/kg) had indefinite allograft survival (median survival time [MST], >100 days). UDCA also suppressed proliferation of splenocytes and production of interleukin (IL)-2, IL-6, and interferon-gamma, and up-regulated IL-10 production. Adoptive transfer of either whole splenocytes or CD4+ cells from UDCA-treated allograft recipients resulted in indefinite survival of allografts in naive secondary recipients (MST, >100 days). Adoptive transfer of CD4+ CD25+ cells from UDCA-treated recipients significantly prolonged allograft survival in naive secondary recipients (MST, >80 days). FK506 (0.1 mg/kg/day) was compatible with the induction of indefinite allograft survival by UDCA, whereas CyA (10 mg/kg/day) abrogated the effect of UDCA. CONCLUSION UDCA induced unresponsiveness to fully allogeneic cardiac allografts and generated CD4+ CD25+ regulatory cells in our model. FK506, but not CyA, was compatible with UDCA treatment.

Abstract
Fish oil, which is rich in eicosapentaenoic acid (EPA), has been found to have immunomodulatory effects. We examined whether administration of purified EPA affected survival of fully mismatched murine cardiac allografts. Hearts from C57BL/10 (H-2(b)) mice were transplanted into CBA (H-2(k)) recipients treated with one intraperitoneal dose of purified EPA the day of transplantation. Untreated CBA recipients and recipients given 0.1 g/kg of EPA rejected C57BL/10 hearts (median survival time [MST], 8 and 13 days, respectively). With a 1.0 g/kg dose of EPA, graft survival was markedly prolonged (MST >100 days). To determine whether regulatory cells were generated, naïve mice (secondary recipients) underwent adoptive transfer of splenocytes from EPA-treated primary recipients and cardiac allograft transplantation. Adoptive transfer of whole, CD4(+) and CD4(+)CD25(+) splenocytes from EPA-treated recipients induced indefinite survival in secondary recipients. Flow cytometry showed that the CD4(+)CD25(+) cells were Foxp3(+). In reverse transcriptase-polymerase chain reaction (RT-PCR) studies, the expression of peroxisome proliferator-activated receptor gamma (PPARgamma) mRNA was upregulated by EPA treatment. A PPARgamma antagonist abrogated the prolongation of graft survival induced by EPA treatment (MST, 13 days). Thus, in our model, purified EPA induced prolonged survival of fully mismatched cardiac allografts and generated regulatory T cells dependent on PPARgamma activation.
