摘要:
The present invention provides a composition of matter comprising a defective interfering virus particle, wherein said particle naturally occurs in a human infection and wherein said particles has a naturally occurring core antigen internal deletion. Provided is a pharmaceutical composition, comprising defective interfering virus particle and a pharmaceutically acceptable carrier. Provided is a method for preparing defective interfering virus, comprising the steps of: (1) introduce a defective interfering virus and a complementing plasmid expressing a wild type virus core antigen and optionally containing a drug resistance gene, into a recipient cell; (2) selecting for stably transfected colonies; (3) growing the drug resistant cells and screening for the production of virus DNA replication; and (4) collecting defective interfering virus particles from the medium. Further provided is a vaccine, comprising a defective interfering virus particle.
摘要:
Trans-differentiation induced by dexamethasone with or without oncostatin M results in cells that are capable of propagating and replicating hepatitis virus. Such trans-differentiated cells are useful for screening drugs that may affect the propagation and replication of hepatitis virus such as hepatitis B virus or hepatitis C virus.
摘要:
Novel methods for stable in vitro propagation of human hepatitis virus using non-human hepatocytes are disclosed. Also discussed are novel systems for efficient expression and secretion of foreign genes employing particular rat hepatoma cells.
摘要:
An antimicrobial peptide, the peptide comprising 2 to 20 variable domains, each variable domain is a sequence of 2 to 20 consecutive basic amino acids, wherein (a) the variable domains are separated from each other by a variable linker, (b) the variable linker can have 1 to 20 any amino acids other than two or more consecutive basic amino acids, and (c) the peptide has no more than 100 amino acids.
