Chinese hamster ovary (CHO) cells have recently been used for identification of receptors for several alphaherpesviruses, including pseudorabies virus (PrV) (R. J. Geraghty, C. Krummenacher, G. H. Cohen, R. J. Eisenberg, and P. G. Spear, Science 280:1618-1620, 1998). The experiments were based on the fact that CHO cells are inefficient target cells for PrV. However, a detailed analysis of the i...
A previous study (Ding et al., 2003) showed that the homeodomain transcription factor DRG11 is necessary for pattern formation in the trigeminal nucleus principalis (PrV), the requisite brainstem nucleus for development of the whisker-to-barrel cortex pathway. However, it is not known how DRG11 contributes to pattern formation. Anatomical studies were performed in DRG11 knock-out (-/-) and DRG1...
Protection of mice and swine from pseudorabies virus conferred by vaccinia virus-based recombinants.
Glycoproteins gp50, gII, and gIII of pseudorabies virus (PRV) were expressed either individually or in combination by vaccinia virus recombinants. In vitro analysis by immunoprecipitation and immunofluorescence demonstrated the expression of a gII protein of approximately 120 kDa that was proteolytically processed to the gIIb (67- to 74-kDa) and gIIc (58-kDa) mature protein species similar to t...
Pseudorabies virus (PRV) is endemic in some regions of Japan. We investigated the effects of PRV infection status on herd productivity. Serum samples were obtained from 48 swine herds in Japan. Within each herd, three serum samples were obtained from growing pigs at four different ages, as well as from sows in low and high parity groups. Sera were tested for antibodies against wild-type PRV via...
Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed salmon frequently experience environmental hypoxia, the current study examined mutual effects of PRV infection and hypoxia on pathogenesis and fish performance. Furthermore, effe...
We compared the levels of latent pseudorabies virus (PRV) DNA in trigeminal ganglia (TG) of pigs after intranasal inoculation of different PRV strains by using quantitative DNA PCR. The extent of colonization attained in each case varied significantly according to the type of strain and inoculum dose, wild-type (WT) PRV being the most efficient strain in colonizing TG. When groups of pigs repre...
Herpesvirus glycoproteins play dominant roles in the initiation of infection of target cells in culture and thus may also influence viral tropism in vivo. Whereas the relative contribution of several nonessential glycoproteins to neurovirulence and neurotropism of Pseudorabies virus (PrV), an alphaherpesvirus which causes Aujeszky's disease in pigs, has recently been uncovered in studies using ...
To evaluate the feasibility of using pseudorabies virus (PrV) glycoprotein B (gB) as a carrier of foot and mouth disease virus (FMDV) antigens in DNA immunization, FMDV B- and T-cell epitopes were inserted either between the two B-cell epitopes of the N-term subunit of PrV-gB (BT-PrV-gB-N-term construct) or within the B-cell epitope of the C-term subunit of PrV-gB (BT-PrV-gB-C-term construct). ...
The cDNA for polycythemia rubra vera 1 (PRV-1), a novel hematopoietic receptor, was recently cloned by virtue of its overexpression in patients with polycythemia vera. PRV-1 is a member of the uPAR/CD59/Ly6 family of cell surface receptors, which share a common cysteine-rich domain and are tethered to the cell surface via a glycosylphosphatidylinositol (GPI) link. We have determined the intron-...
نظر به رشد جمعیت و بحران منابع آب در بخش وسیعی از کشورهای دنیا، مقوله نشت در شبکه های آبرسانی شهری اهمیت زیادی یافته است. در سالیان اخیر راهکارهای مختلفی که منجر به کاهش نشت می گردند مورد توجه محققین و مدیران صنعت آب قرار گرفته است. مدیریت فشار یکی از کاراترین و مقرون به صرفه ترین روشهای کاهش نشت می باشد. مقاله حاضر روشی را جهت کاهش نشت در شبکه های توزیع آب شهری از طریق کمینه نمودن مجموع مربع...
