Active infection with torquetenovirus (TTV) has been associated with an increased severity of diseases in which inflammation plays a particularly important pathogenetic role. Here, we report that cloned DNA of a genogroup 4 TTV (ViPiSAL) is an activator of proinflammatory cytokine production by murine spleen cells and that the effect is mediated via toll-like receptor (TLR)9. The same DNA also ...

The signalling molecule Hedgehog (Hh) functions as a morphogen to pattern a field of cells in animal development. Previous studies in Drosophila have demonstrated that Tout-velu (Ttv), a heparan sulphate polymerase, is required for Hh movement across receiving cells. However, the molecular mechanism of Ttv- mediated Hh movement is poorly defined. We show that Dally and Dally-like (Dly), two Dro...

An infectious etiology has been proposed for many human cancers, but rarely have specific agents been identified. One difficulty has been the need to propagate cancer cells in vitro to produce the infectious agent in detectable quantity. We hypothesized that genome amplification from small numbers of cells could be adapted to circumvent this difficulty. A patient with concomitant chronic lympho...

The objectives of this study were to investigate the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), human T-lymphotropic virus types 1 and 2 (HTLV-1/2), Torque teno virus (TTV) and Toxoplasma gondii (T. gondii) infection among men who have sex with men (MSM) in Surakarta, Indonesia, and the risk factors and sexual beh...

OBJECTIVE To determine the prevalence of GB virus-C (GBV-C) RNA and TT virus (TTV) DNA in patients with systemic sclerosis (SSc), rheumatoid arthritis (RA), and osteoarthritis (OA) as well as to compare the autoantibody pattern in patients with SSc with and without evidence of viral infection. PATIENTS AND METHODS The study included 168 patients (84 SSc, 41 RA, and 43 OA) diagnosed according ...

OBJECTIVE To assess associations between nonalcoholic fatty liver disease (NAFLD) and measures of brain health in a population-based sample of adults. METHODS Participants from the CARDIA study (Y25 exam; age 43-55 years) with concurrent computed tomography quantification of liver fat, visceral adipose tissue (VAT), and brain magnetic resonance (MR) images were included (n = 505). NAFLD was i...

SEN virus (SENV) is a circular, single stranded DNA virus that has been first characterized in the serum of a human immunodeficiency virus type 1 (HIV-1)-infected patient. Eight genotypes of SENV (A-H) have been identified and further recognized as variants of TT virus (TTV) in the family Circoviridae. Here we describe the first genomic characterization of a SENV isolate (5-A) from South Americ...

مقدمه: ویروس TT ( TTV ) یک ویروس بدون پوشش با DNA تک‌رشته‌ای حلقوی است که مطالعات صورت گرفته با استفاده از سیستم‌های PCR (واکنش زنجیره‌ای پلیمراز) حساس، همراه با پرایمرهای طراحی شده برای مناطق بسیار محافظت شده ژنوم ویروسی( UTR ) حاکی از شیوع بسیار بالای (بیش از90 ٪ ) آلودگی TTV در بین جمعیت‌های عمومی سراسر جهان می‌باشد. بررسی‌ها نتوانسته‌اند نقش TTV را در بدن و همچنین ارتباط آن را با بیماری کبد...

  چکید ه   سابقه و هدف   امروزه انتقال خون به عنوان یک درمان حیاتی، نقش مهمی در پزشکی بالینی پیدا کرده‌است اما این روش درمانی همیشه با خطر انتقال عوامل عفونت‌زای ویروسی مانند هپاتیت و رتروویروس‌ها همراه می‌باشد. در سالیان اخیر، تحقیقات زیادی با هدف شناسایی این عوامل صورت گرفته‌ است. نتیجه این تحقیقات در سال 1997 موجب شناسایی ویروس TTV توسط نیشیزاوا گردید. هدف از انجام مطالعه با توجه به عدم وجود...

The Anelloviridae family consists of non-enveloped, circular, single-stranded DNA viruses. Three genera of anellovirus are known to infect humans, named TTV, TTMDV, and TTMV. Although anelloviruses were initially thought to cause non-A-G viral hepatitis, continued research has shown no definitive associations between anellovirus and human disease to date. Using high-throughput sequencing, we in...
