there are many studies related to the production of a elisa kit for diagnosing virus infections. however, production of most kits depends on purification of whole virus particles, which involves the use of costly equipment and reagents. the purpose of this study was to check out if the anti-cp42 antibodies could be used as a diagnostic assay for detection of grapevine fanleaf virus (gflv). in t...

citrus tristeza virus (ctv) is among the most destructive pathogens of citrus and causes substantial economic losses in citrus-growing industry worldwide. considering recent distribution of this pathogen and its capability of transmission by existing aphid vectors in iran, detection of this virus is enforceable for controlling the damage caused by this pathogen in iran, as one of the major citr...

A 19-kDa lipoprotein from Mycobacterium tuberculosis was expressed as a recombinant antigen in the nonpathogenic mycobacterial host strain M. vaccae. Immunization of mice with the recombinant M. vaccae resulted in induction of a strong type 1 immune response to the 19-kDa antigen, characterized by immunoglobulin G2a (IgG2a) antibodies and gamma interferon (IFN-gamma) production by splenocytes. ...

The induction of strong CD8(+) T-cell responses against infectious diseases and cancer has remained a major challenge. Depending on the source of antigen and the infectious agent, priming of CD8(+) T cells requires direct and/or cross-presentation of antigenic peptides on major histocompatibility complex (MHC) class I molecules by professional antigen-presenting cells (APCs). However, both path...

Mannheimia haemolytica is responsible for considerable economic losses to cattle, sheep, and goat industries in many parts of the world. This bacterium isone of the causative agents of shipping fever in cattle. Current vaccines against M. haemolytica are moderately efficacious since they do not provide complete protection against the disease. Production of a...

objective(s): hepatitis c is a major cause of liver failure worldwide. current therapies applied for this disease are not fully effective and produce side effects in most cases. non-structural protein 3 helicase (ns3) of hcv is one of the key enzymes in viral replication and infection. therefore, this region is a promising target to design new drugs and therapies against hcv infection. the aim ...

background: the immunogenic brucella abortus ribosomal protein l7/l12 is a promising candidate antigen for the development of subunit vaccines against brucellosis. objective: this study was aimed to evaluate the protection of recombinant human serum albumin (has)-l7/l12 fusion protein in balb/c mice. methods: the amplified l7/l12 gene was cloned in pyhsa5 vector, pyhsa5-l7/l12 construct was tra...

The present study compared the efficacy of Microscopic Agglutination Test (MAT) with UpL32 and UpL41 recombinant antigen based Enzyme-linked immunosorbent assay (ELISA) for the diagnosis of bovine leptospirosis. The UpL32 and 41 genes were amplified using specific primers and the polymerase chain reaction products (peR) were cloned. The gene inserts from positive recombinant clones were inserte...

Objective(s): Breast cancer is one of the most common cancers in the world and is on the increase. MUC1 and HER2 as tumor-associated antigens (TAAs) are abnormally expressed to some extent in 75–80% of breast cancers.  In our present research, a novel chimeric MUC1-HER2 (HM) protein was designed and used to study whether an immune response can be generated against these TAAs. In vitro analysis ...
