OBJECTIVE The inhibitory effect of active ingredients of Tripterygium wilfordii Hook.F.(TWHF)(celastrol,triptolide,triptonide,wilforlide A,wilforgine and wilforine)on human carboxylester⁃ase 1(CES1)and CES2 was detected to investigate the herb-drug interactions(HDIs)of TWHF.METHODS Human liver microsomes catalysed hydrolysis of 2-(2-benzoyl-3-methoxyphenyl)benzothi⁃azole(BMBT)and fluorescein diacetate(FD)were used as the probe reaction to phenotype the activity of CES1 and CES2,respectively.The residual activities of CES1 and CES2 were detected by ultrahigh performance liquid chromatography(UPLC)after intervention with celastrol,triptolide,triptonide,wilforlide A,wilforgine and wilforine(100μmol·L^(-1)).Kinetics analysis,involving half inhibitory concentra⁃tion(IC_(50)),inhibition type and kinetic parameter(Ki),and in vitro-in vivo extrapolation(IVIVE),was carried out to predict the HDIs between these compounds and CES-metabolizing drugs.Molecular docking was performed to analyze the ligand-enzyme interaction.RESULTS Out of the six main con⁃stituents of TWHF,only celastrol exhibited strong inhibition towards both CES1 and CES2,with the inhibitory rates of 97.45%(P<0.05)and 95.62%(P<0.05),respectively.The IC_(50)was 9.95 and 4.02 mol·L^(-1),respectively,and the types of inhibition were all non-competitive inhibition.Based on the kinetics analysis,the Ki values were calculated to be 5.10 and 10.55μmol·L^(-1)for the inhibition of celastrol on CES1 and CES2,respectively.IVIVE indicated that celastrol might disturb the metabolic hydrolysis of clinical drugs in vivo by inhibiting CES1.Molecular docking results showed that hydrogen bonds and hydrophobic contacts contributed to the interaction of celastrol and CESs.CONCLUSION The inhibitory effect of celastrol on CES1 and CES2 might cause HDIs with clinical drugs hydrolysed by CESs. 展开更多

In this study a reliable protocol was developed for the establishment of commercial in vitro cultures of Tripterygium wilfordii Hook f.. Juvenile shoots from one-year-old elite plants were used as the source of explants. New axillary shoots were obtained after 30 days of culture on a MS medium supplemented with BAP (2.0 mg.L^-1) and NAA (0.1 mg.L^-1). The optimal multiplication medium was a modified MS medium supplemented with BAP (1.0 mg.L^-1) and NAA (0.1 mg.L^-1). This yielded a multiplication rate of 2.4 for each subculture. Slightly more than 92% of shoots rooted when cultured on a modified MS medium containing IBA (0.2 mg.L^-1) and activated charcoal (0.5 mg.L^-1). Activated charcoal promoted both a strong and a high rooting rate during the rooting phase. Plantlets were transferred to pots for a short acclimatization stage in a greenhouse where 95% of the plantlets survived. This highly reproducible procedure can be adopted for large-scale propagation of T. wilfordii. 展开更多

Purpose:Toexamine the effect of Tii treatment of cornea graft survival in a rab-bit model.Methods:Tii was administrated orally after eccentrical corneal transplantation.Survival times were determined by biomicroscopy.Cytotoxic T lymphocytes(CTL)and delayed-type hypersensitivity(DTH)responses to donor alloantigens were assessed at ady 16after heterotopic corneal grafts.Results:Administration of Tii reduced the incidence and prologed the graft sur-vival time.Both CTLand DTH responses to donor alloantigens were severely ed-pressed in hosts treated with Tii.However,combination of Tii and cyclosporine further enhanced the immunosuppressive effects described above.Conclusions:Tii is a potent immunosuppressant with the ability to prolong allo-graft survival in the rabbit penetrating keratoplasty model and may have coordi-native effects with CsA through different mechanisms.Further studies are neces-sary to define any potentially coordinative role in the prevention of allograft rejec-tion in human keratoplasty.Eye Science 1995;11:168-172. 展开更多

AIM: To analyze the gene expression profiles of mice livers injured by Leigongteng and explore the relationship between the differentially expressed genes and liver damage. METHODS: The experimental mice were randomly divided into a control group and a liver-injured group in which the mice were administrated 33 μγ, of triptolide/ kg per day for 30 d. Liver mRNAs were extracted from animals in both groups and were reverse-transcribed to cDNA with dUTP labeled by different fluorescence (Cy3, Cy5) as hybridization probes. The mixed probes were hybridized with oligonucleotide microarray chips. The fluorescent signal results were acquired by scanner and analyzed with software. RESULTS: Among the 35852 target genes, 29 genes were found to be significantly differentially expressed, with 20 genes up-regulated and 9 genes down-regulated. The reliability of the differentially expressed genes was validated by RT-PCR experiments of 5 randomly selected differentially expressed genes. CONCLUSION: Based on the biological functions of the differentially expressed genes, it is obvious that the occurrence and development of liver damage induced by Leigongteng in mice are highly associated with immune response, metabolism, apoptosis and the cell skeleton of liver cells. This might be important for elucidating the regulatory network of gene expression associated with liver damage and it may also be important for discovering the pathogenic mechanisms of liver damage induced by Leigongteng. 展开更多

The principal pathology of Alzheimer's disease includes neuronal extracellular deposition of amyloid-beta peptides and formation of senile pl aques, which in turn induce neuroinflammation in the brain. Triptolide, a natural extract from the vine-like herb Tripterygium wilfordii Hook F, has potent anti-inflammatory and immunosuppressive efficacy. Therefore, we determined if triptolide can inhibit activation and proliferation of microglial cells and astrocytes in the APP/PS1 double transgenic mouse model of Alzheimer's disease. We used 1 or 5 μg/kg/d triptolide to treat APP/PS1 double transgenic mice (aged 4-4.5 months) for 45 days. Unbiased stereology analysis found that triptolide dose-dependent- ly reduced the total number of microglial cells, and transformed microglial cells into the resting state. Further, triptolide (5 μg/kg/d) also reduced the total number of hippocampal astrocytes. Our in vivo test results indicate that triptolide suppresses activation and proliferation of microglial cells and astrocytes in the hippocampus of APP/PS 1 double transgenic mice with Alzheimer's disease. 展开更多

Tripterygium wilfordii Hook F (TwHF) and its extracts have long been used for the treatment of rheumatoid arthritis, autoimmune diseases, and kidney disease due to their anti-inflammatory, immunoregulatory, and other pharmacological effects. However, the clinical immunoregulatory effects of TwHF and its extracts remain unclear, so we reviewed their effects for use in clinical practice. This review provides a comprehensive summary of the recent literature on the immunoregulatory effects of TwHF and its extracts in clinical studies. TwHF and its extracts affect the proliferation and activation of T and B cells;ratio of T cell subsets;inflammatory response of monocytes, macrophages, and immunoglobulins;and secretion of many cytokines. Together, these effects dictate immune function in a variety of diseases. TwHF and its extracts can be used alone or in combination with existing therapies against many immune disorders through immunomodulation. 展开更多

(TWH) users were investigated by electron microscopy. No macrophages were demonstrated in the 21 specimens collected prior to the administration of TWH. However, it was found in 23 out of the 48 semen specimens obtained following the TWH administration. The macrophages were functionally active as shown by the presence of a large number of cytoplasmic processes and pseudopodia on the surface, and primary and secondary lysosomes in the cytoplasm. The macrophages phagocytized sperm debris and degenerated or dead spermatids with formation of specific phagosomes. Around those macrophages, lymphocytes were commonly noted. The cytoplasmic processes of the two cell types could come into contact or even fuse with each other, leading to tight junction-like structure; in some of the contacts, the plasma membranes were found dissolved so as to form direct cytoplasmic linkage. 展开更多

Prolonged antiretroviral therapy(ART)-free remission post-treatment has been observed and reported in human immunodeficiency virus-1(HIV-1)infection.The primary factors for such achievement have been linked to the transcriptional inactivation of HIV-1 DNA and immune recovery.Here,we reported a patient with acute HIV-1 infection who immediately received intensified quadruple ART.At month 9(M9),an old CFDA-approved immuno-suppressive herbal medicine,Tripterygium Wilfordii Hook F(TwHF),was used in addition to ART.The patient was closely monitored.Virological and immunological tests as well as transcriptome analysis were carried out at each visit.The results showed that TwHF reduced serum IP-10 level and inhibited T cell activation.Both ART and TwHF were discontinued in M24,and levels of peripheral blood HIV-1 RNA and DNA remained suppressed for consecutive 12months.With transcriptome analysis,we found pattern changes linking immuno-activation and amino acid metabolism with viral suppression and rebound.This indicates that the intentional suppression of immuno-activation is a promising approach for a functional cure of HIV-1 infection. 展开更多

To examine the effect of multi-glycoside of Tripterygium wilfordii Hook. f. (GTW) on proteinuria and acute glomerular immune lesion in experimental mesangial proliferative glomerulonephritis (MsPGN) induced by anti-Thyl. 1 monoelonal antibody (mAb) 1-22-3. The reversible model of MsPGN with anti-Thyl. 1 mAb 1-22-3 was established. After 7 days of oral treatment with GTW ( 100 mg/kg per day) and vehicle (distilled water, 5 ml/kg per day), its effects on proteinuria, renal functions, mesangial morphological change, glomerular macrophage accumulation, and mRNA expressions of cytokines (PDGF-BB and MCP-1 ) were evaluated by light microscope (LM), immunofluorescence (IF), and reverse transcription polymerase chain reaction (RT-PCR). It was found that GTW ameliorated proteinuria (on day 3 and day 7), mesangial proliferation (total cell number, matrix expansion, a-smooth muscle actin expression, and collagen type Ⅰ expression) and macrophage accumulation (ED3^+ ) in experimental MsPGN. In addition, GTW significantly suppressed the increased mRNA expressions for MCP-1 (67.6% to eontrol group, P 〈 0.01) together with the tendency to reduce the expression of PDGF (24.44% to control group) on day 7. It is concluded that GTW can not only decrease proteinuria, but also ameliorate acute mesangial alterations and glomerular activated macrophage accumulation probably by reduction of cytokines. These data indicate that GTW is an effective agent for early MsPGN. 展开更多
