Construction of recombinant murine retroviruses that express the human T-cell leukemia virus type II and human T-cell lymphotropic virus type III trans activator genes.
Recombinant retroviruses containing the trans activator genes of human T-cell leukemia virus (HTLV) type II and human T-cell lymphotropic virus type III were constructed. The trans activator genes tat II and tat III were inserted into the murine retroviral vector pZIPNEOSV(X)1. Recombinant plasmids were transfected into the psi 2 and psi AM packaging cell lines that produce murine leukemia viri...
متن کاملVaccination against δ−Retroviruses: The Bovine Leukemia Virus Paradigm
Bovine leukemia virus (BLV) and human T-lymphotropic virus type 1 (HTLV-1) are closely related d-retroviruses that induce hematological diseases. HTLV-1 infects about 15 million people worldwide, mainly in subtropical areas. HTLV-1 induces a wide spectrum of diseases (e.g., HTLV-associated myelopathy/tropical spastic paraparesis) and leukemia/lymphoma (adult T-cell leukemia). Bovine leukemia vi...
متن کاملOptimizing refolding condition for recombinant tissue plasminogen activator
Low molecular size additives such as L-arginine and the redox compounds have been used both in the culturemedium and in vitro refolding to increase recombinant proteins production. Additives increase proteinrefolding and yield of active proteins by suppressing aggregate formation or enhancing refolding process.In this work, a comparative study was performed on refolding of rec...
متن کاملA refined kinetic analysis of plasminogen activation by recombinant bovine tissue-type plasminogen activator indicates two interconvertible activator forms.
Bovine tissue-type plasminogen activator (tPA) was heterologously expressed in the methylotrophic yeast Pichia pastoris and characterized structurally and kinetically. The bovine single-chain tPA-mediated activation of bovine plasminogen was studied in the presence and absence of fibrinogen fragments. We have proposed a refined new method of kinetic analysis which allows examination of both sta...
متن کاملThe Outcome of Treatment With Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke
Background: Thrombolytic therapy is the recommended treatment of acute ischemic stroke. It is crucial to evaluate the treatment results with recombinant Tissue Plasminogen Activator (r-TPA) in patients with acute stroke. Objectives: This study aimed to evaluate treatment outcomes with r-TPA in patients with acute stroke in a referral stroke center in Iran. Materials & Methods: In this retrosp...
