This invention provides peptides that might be potent inhibitors of HIV replication, in both macrophages and T lymphocytes. Specifically, the inventors have identified peptides, from the HIV-1 gp120 envelope protein, that share structural similarities with chemokines and are shown to block “docking” interactions between the HIV-1 envelope protein gp120 and chemokine receptors that function as “coreceptors” for HIV entry on the surface of target cells (macrophages and T lymphocytes). The inventors synthesized two peptides (designated 15K and 15D) based on this information and showed that both were effective in competing with chemokines for binding to CCR5- and CXCR4-expressing cells. These peptides efficiently inhibited infection of human monocyte derived macrophages and peripheral blood mononuclear cells by different strains of HIV. The synthesized peptides also inhibited chemotaxis of CCR5 expressing transfected cells stimulated by the chemokine RANTES. Thus, these peptides and other molecules based on their structure can be potentially used as inhibitors of HIV. Moreover, these peptides could also have anti-inflammatory and anti-tumor activity. Further, it has been determined that these peptides are multi-tropic in their effects (blocking HIV interactions with multiple co-receptors) for blocking both T cell tropic (lymphotropic) and macrophage tropic (m-tropic) HIV strains.

The inventors have isolated a number of previously unknown sRNAs found in E. coli. Previous scientific publications by the inventors and others regarding sRNAs have shown these sRNAs to serve important regulatory roles in the cell, such as regulators of virulence and survival in host cells. Prediction of the presence of genes encoding sRNAs was accomplished by combining sequence information from highly conserved intergenic regions with information about the expected transcription of neighboring genes. Microarray analysis also was used to identify likely candidates. Northern blot analyses were then carried out to demonstrate the presence of the sRNAs. Three of the sRNAs claimed in the invention regulate (candidates 12 and 14, negatively and candidate 31, positively) expression of RpoS, a major transcription factor in bacteria that is important in many pathogens because it regulates (amongst other things) virulence. The inventors' data show that these sRNAs are highly conserved among closely related bacterial species, including Salmonella and Klebsiella presenting a unique opportunity to develop both specific and broad-based antibiotic therapeutics. The invention contemplates a number of uses for the sRNAs, including, but not limited to, inhibition by antisense, manipulation of gene expression, and possible vaccine candidates.

Decoding Algorithm for Neuronal Responses

The invention is a new algorithm for decoding neuronal responses based on Start Printed Page 18100the discovery that neuronal spike trains can be described using order statistics. The device has applications in the direct control of prosthetic limbs by neuronal signals originating from electrodes placed in the brain. The method allows for decoding neuronal responses by monitoring sequences of potentials from neurons while specific motor tasks are carried out. The sequences are then characterized using the innovative technique of applying order statistics to the spike train, such that subsequent action potentials representing unidentified motor tasks can be decoded to determine the unknown task. The invention is of substantial importance because it appears to have achieved a closed form interpretation of neuronal responses upon which a motor prosthetic device might be based.

Expression Vectors Able to Elicit Improved Immune Response and Methods of Using Same

Pavlakis et al. (NCI)

Cellular immune responses against human immunodeficiency virus type 1 (HIV-1) and the related simian immunodeficiency virus (SIV) have been shown to play an important role in controlling HIV-1 and SIV infection and in delaying disease progression. This invention relates to nucleic acids (such as DNA immunization plasmids), encoding fusion proteins containing a destabilizing amino acid sequence which increases their immunogenicity. In order to make HIV gag or env more immunogenic, several signals for proteasomal degradation were selected and linked to the proteins. One of these destabilizing amino acid sequences was found to be particularly effective. The DNA construct expressing the HIV-1 gag fusion protein was more immunogenic in mice than the HIV gag protein. Compared with gag alone, the DNA expressing the gag fusion protein evoked much higher HIV-specific proliferative responses, elevated CTL response and a high level of CD8+ IFNg-secreting cells.
