摘要:
Disclosed herein are packaging cell lines, in which adenovirus (Ad) E1A is constitutively expressed, that also contain integrated AAV rep and cap genes. The packaging cell lines exhibit little to no expressed Rep protein until helper virus function, such as adenovirus (Ad) E4, E2A and/or VA RNA are provided by, for example, transduction of the cells with a virus, vector or plasmid, such as an Ad-AAV hybrid virus. The promoter driving expression of AAV rep gene can be positioned far enough upstream (5') of the rep coding sequence that E1A is unable to activate the promoter, activate substantial transcription of the rep gene and in turn produce Rep protein. Introduction of helper virus function, such as E2A, E4 and/or VA RNA into these packaging cells is able to drive AAV rep gene transcription, subsequent Rep protein expression and production of rAAV vector particles.

Provided are methods for producing recombinant adeno-associated virus (rAAV) vector particles at high recovery or high titer. Also provided are methods that concentrate rAAV vectors to a high concentration, for example, up to 5E+13 (5x10 13 ) vector genomes per milliliter (Vg/ml) with little if any rAAV aggregates.

A method of stimulating or promoting plant growth includes applying to a crop plant a composition of ipfencarbazone in an amount sufficient to stimulate or promote plant growth. In some aspects, embodiments herein provide methods of stimulating or promoting plant growth comprising applying to a crop plant a composition comprising ipfencarbazone in an amount sufficient to stimulate or promote plant growth.
摘要:
The invention relates to novel targets for immune response modulation, treatment of tuberculosis infection and epitopes of Mycobacterium tuberculosis, or subsequences, portions or modifications thereof, and methods and compounds for treatment and prevention of tuberculosis infection. The invention is based, in part, on the discovery of novel Mycobacterium tuberculosis and non-tuberculosis mycobacterium T cell epitopes and use of such epitopes in treatment and vaccination methods. In particular embodiments, the invention provides proteins and peptides comprising amino acid sequences of Mycobacterium tuberculosis and non-tuberculosis mycobacterium proteins, and subsequences, portions or modifications, and methods and compounds comprising such protein and peptides for the treatment, diagnosis and prevention of Mycobacterium tuberculosis and non-tuberculosis mycobacterium infection.
摘要:
Compounds, uses and methods for modulating an immune response are provided. In particular, modulating the interaction of PKCη with CTLA-4 can modulate an immune response. For example, modulating activity or expression of PKCη, and/or modulating activity or expression of CTLA-4, can be used to modulate interaction of PKCη with CTLA-4, thereby modulating an immune response.
