    摘要: Skin cells are genetically altered to express a gene product encoded by an introduced polynucleotide. Specifically, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide that is substantially free of liposomes or charged lipids, where the skin can be either treated or untreated prior to application. Similarly, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide formulation comprising a liposome or charged lipid, wherein the skin is not treated by removal of hair prior to application. The method of the invention serves as a platform for delivering polynucleotides to skin cells for expression therein for any of a variety of uses including, but not limited to genetic immunization.

    摘要: A two-step, scalable method is described for identifying the cellular function(s) of one or more genes of unknown function, and for identifying modulators or the gene(s). The method uses the reversal or alteration of a phenotype created by the expression of the heterologous gene, e.g., a human gene, to identify modulators of that gene's activity. That modulator is then used in an in vitro or in vivo disease model system to identify compounds which affect disease progression. The subset of compounds which influence disease in a therapeutic manner are drug leads. However, all compounds which influence disease progression are tools to at least partially characterize gene function. The inhibitor identification step or the method is preferably carried out using a plurality of microbial strains or cell lines expressing different heterologous DNA sequences in a single solution. The method is particularly useful for genes which have not been validated as good inhibitor targets.

    摘要: The present invention pertains generally to novel Neisseria meningitidis serogroup B glycoconjugates. More particularly, the invention pertains to glycoconjugates formed from a Neisseria meningitidis serogroup B capsular oligosaccharide derivative (MenB OS derivative) in which sialic acid residue N-acetyl groups are replaced with N-acyl groups. The invention also pertains to vaccine formulations containing the glycoconjugates, methods of making the vaccine formulations, and methods of using the vaccine formulations to treat or prevent Neisseria meningitidis serogroup B or E. coli K1 disease in a mammalian subject.
