    Abstract: The invention provides immunostimulatory compositions and methods for their use. In particular, the immunostimulatory compositions of the invention include RNA-like polymers that incorporate an immunostimulatory sequence motif and at least one chemical modification to confer improved stability against nuclease degradation and improved activity. Specific modifications involving phosphate linkages, nucleotide analogs, and combinations thereof are provided. Compositions of the invention optionally include an antigen and can be used to stimulate an immune response. Also provided are compositions and methods useful for treating a subject having an infection, a cancer, an allergic condition, or asthma. Modified oligoribonucleotide analogs of the invention are believed to stimulate Toll-like receptors TLR7 and TLR8.

    Abstract: A new method for an antibiotic-free selection of genetically modified cells is described. It is shown that antisense molecules targeted to an essential cellular gene inhibits growth and is suited as an agent for growth selection of cells transformed with a plasmid carrying an altered version of the essential gene. The results show that antisense molecules may be used for antibiotic-free selection of desired transformed microbes when targeted against an essential microbial gene. This technology is useful in genetic engineering for research growth and isolation of transformed organisms, and for industrial growth maintenance of transformed organisms, e.g. in the production of genetically engineered proteins as an environmentally safer alternative to traditional selection methods based on antibiotics.
