摘要:
Anti-viral therapeutics for use in viral targets having VPg unlinkase activity, including the broad class of picornaviruses, and therapeutic methods directed at suppression of such activity are provided. Such anti-viral therapies for use against human rhinovirus, for example, are particularly desirable as they would lessen both the severity and duration of upper respiratory distress in both normal and asthmatic individuals. Assays and purification protocols for detecting and purifying VPg unlinkase are also provided.

The invention provides an attenuated polio virus having a 5′ non-coding region consisting of the 5′ non-coding region of Sabin 3, modified so that it does not have a base pair mismatch in stem (a) or (b) of domain V, wherein seven or eight of the base pairs in stems (a) and (b) are U-A or A-U base pairs; and a capsid protein from the Sabin 1, Mahoney, MEF or Saukett strain.
摘要:
The inventors discovered that the adhesion molecule CAR, known to be localized in intracellular adhesion sites, functioned as an adhesion molecule for activated lymphocytes. Further, the inventors identified CARL, a novel CAR ligand expressed in lymphocytes, and clarified that the ligand was expressed selectively in Th1 cells. In addition, they found that anti-CAR antibodies could inhibit the adhesion of activated lymphocytes to CAR molecules. Thus, the present invention provides methods for detecting Th1 cells using CAR or anti-CARL antibodies, and methods of screening for inhibitors suppressing the adhesion of Th1 cells using the binding between CAR and CARL as an index. Furthermore, the present invention relates to methods of screening for inhibitors of the binding between CAR and CARL, antibodies that inhibit the binding between CAR and CARL, and therapeutic compositions comprising these antibodies. These are expected to be useful in diagnosing diseases, such as inflammation, in which infiltration of Th1 cells is involved, and in providing pharmaceutical agents for alleviating such diseases.
摘要:
The present invention relates to a novel RNA picornavirus that is called Seneca Valley virus (“SVV”). The invention provides isolated SVV nucleic acids and proteins encoded by these nucleic acids. Further, the invention provides antibodies that are raised against the SVV proteins. Because SVV has the ability to selectively kill some types of tumors, the invention provides methods of using SVV and SVV polypeptides to treat cancer. Because SVV specifically targets certain tumors, the invention provides methods of using SVV nucleic acids and proteins to detect cancer. Additionally, due to the information provided by the tumor-specific mechanisms of SVV, the invention provides methods of making new oncolytic virus derivatives and of altering viruses to have tumor-specific tropisms.

摘要:
The present disclosure relates to chimeric tymovirus-like particles (TVLPs) comprising a fusion protein that further comprises of a first protein that is a truncated tymovirus coat protein and a second protein. These chimeric TVLPs are useful as antigens. The present disclosure provides a highly efficient means for differentiating Foot and Mouth Disease Virus (FMDV) infected animals from vaccinated animals. The present disclosure further provides a process for the production of chimeric TVLPs and a diagnostic kit for the determination of specific antibodies of FMDV to differentiate FMDV infected from vaccinated animals. The present disclosure also provides the use of the chimeric TVLPs for diagnostic purposes.
摘要:
A method for preparing selected peptide substrates for detecting the activity of virus-specified proteases is provided. Specific tetrapeptide substrates are disclosed which are conjugates of protease-cleavable indicator groups and peptide sequences resembling picornavirus protease cleavage recognition sites.
