Tuftsin–phosphorylcholine (TPC) equally effective to methylprednisolone in ameliorating lupus nephritis in a mice model 下载免费PDF全文
S. Kivity O. Shovman T. Bashi O. Perry A. Watad D. Ben‐Ami Shor A. Volkov I. Barshack N. L. Bragazzi A. Krule M. Fridkin H. Amital M. Blank Y. Shoenfeld 《Clinical and experimental immunology》2018,193(2):160-166
The role of helminth treatment in autoimmune diseases is growing constantly. Systemic lupus erythematosus (SLE) is a multi‐system autoimmune disease with challenging treatment options. Tuftsin–phosphorylcholine (TPC) is a novel helminth‐based compound that modulates the host immune network. This study was conducted to evaluate the potential value of TPC in ameliorating lupus nephritis in a murine model and specifically to compare the efficacy of TPC to the existing first‐line therapy for SLE: corticosteroids (methylprednisolone). Lupus‐prone NZBxW/F1mice were treated with TPC (5 µg/mouse), methylprednisolone (MP; 5 mg/body weight) or phosphate‐buffered saline (PBS) (control) three times per week once glomerulonephritis, defined as proteinuria of grade > 100 mg/dl, was established. Levels of anti‐dsDNA autoantibodies were evaluated by enzyme‐linked immunosorbent assay (ELISA), splenic cytokines were measured in vitro and the kidney microscopy was analysed following staining. TPC and MP treatments improved lupus nephritis significantly and prolonged survival in NZBxW/F1 mice. TPC‐treated mice showed a significantly decreased level of proteinuria (P < 0·001) and anti‐dsDNA antibodies (P < 0·001) compared to PBS‐treated mice. Moreover, TPC and MP inhibited the production of the proinflammatory cytokines interferon IFN‐γ, interleukin IL‐1β and IL‐6 (P < 0·001) and enhanced expression of the anti‐inflammatory cytokine IL‐10 (P < 0·001). Finally, microscopy analysis of the kidneys demonstrated that TPC‐treated mice maintained normal structure equally to MP‐treated mice. These data indicate that the small molecule named TPC hinders lupus development in genetically lupus‐prone mice equally to methylprednisolone in most of the cases. Hence, TCP may be employed as a therapeutic potential for lupus nephritis. 相似文献

Immotile-cilia syndrome with azoospermia: a case report and review of the literature 总被引:2,自引:0,他引:2

A case of immotile-cilia syndrome associated with azoospermia is presented. This diagnosis is based on a typical history of bronchitis, sinusitis, situs inversus, impaired nasal mucociliary clearance and characteristic ultrastructural defect in the respiratory tract cilia and in the sperm tail. Semen analysis showed azoospermia with no evidence of obstruction in the epididymis or vas deferens; there was normal spermatogenesis. 相似文献

Fortyfive patients underwent combined valve replacement and coronary revascularisation from June 1987 to May 1993. Twentytwo
patients underwent MVR and CABG, 21 patients A V Rand CABG and 2 had both aortic and mitral valve replacement in addition
to CABG. Cold potassium blood cardioplegla was used for intraoperative myocardial protection in all the patients. Among those
who underwent A V R and CABG, 3 patients died and 3 others died from among those who underwent MVR and CABG. Both patients
who underwent double valve replacement and CABG did well. Rheumatic mitral lesions were the common indication for MVR in patients
with combined mitral lesions and coronary artery diseases. This is in contrast to western patients, where ischaemic and degenerative
lesions are more common. 相似文献

Novel therapeutic compound tuftsin–phosphorylcholine attenuates collagen‐induced arthritis 下载免费PDF全文

Treatment with helminthes and helminthes ova improved the clinical symptoms of several autoimmune diseases in patients and in animal models. Phosphorylcholine (PC) proved to be the immunomodulatory molecule. We aimed to decipher the tolerogenic potential of tuftsin–PC (TPC), a novel helminth‐based compound in collagen‐induced arthritis (CIA) a mouse model of rheumatoid arthritis (RA). CIA DBA/1 mice were treated with TPC subcutaneously (5 µg/0.1 ml) or orally (250 µg/0.1 ml), starting prior to disease induction. The control groups were treated with PBS. Collagen antibodies were tested by enzyme‐linked immunosorbent assay (ELISA), cytokine protein levels by ELISA kits and regulatory T (Treg) and regulatory B (Breg) cell phenotypes by fluorescence‐activated cell sorter (FACS). TPC‐treated mice had a significantly lower arthritis score of 1.5 in comparison with control mice 11.8 (P < 0.0001) in both subcutaneous and orally treated groups at day 31. Moreover, histology analysis demonstrated highly inflamed joints in control mice, whereas TPC‐treated mice maintained normal joint structure. Furthermore, TPC decreased the titres of circulating collagen II antibodies in mice sera (P < 0.0001), enhanced expression of IL‐10 (P < 0.0001) and inhibited production of tumour necrosis factor (TNF)‐α, interleukin (IL)?17 and IL‐1β (P < 0.0001). TPC significantly expanded the CD4+CD25+ forkhead box protein 3 (FoxP3+) Treg cells and CD19+IL‐10+CD5highCD1dhighT cell immunoglobulin mucin‐1 (TIM‐1+) Breg cell phenotypes (P < 0.0001) in treated mice. Our data indicate that treatment with TPC attenuates CIA in mice demonstrated by low arthritic score and normal joints histology. TPC treatment reduced proinflammatory cytokines and increased anti‐inflammatory cytokine expression, as well as expansion of Treg and Breg cells. Our results may lead to a new approach for a natural therapy for early rheumatoid arthritis onset. 相似文献
