Neutralization of Hepatitis C Virus (HCV)
Description of Technology: Available for licensing and commercial development are anti-hepatitis C virus (HCV) vaccines, therapeutics and inhibitors. The invention is based on mapping studies conducted by the inventors of two epitopes within HCV E2: epitope I and epitope II. It has been discovered that epitope I is involved in virus neutralization but that epitope II mediates antibody interference; probably an adaptation of the virus to obfuscate the immune system. The present invention provides compositions and methods for treating and or preventing HCV infection caused by HCV. The invention is directed to a HCV E2 polypeptide substitution of Start Printed Page 40586amino acids LFY of the skein LFY in epitope II. In certain embodiments, the invention is directed to a HCV E2 polypeptide deletion of amino acids LFY of the skein LFY in epitope II. In additional embodiments, the invention is directed to a HCV E2 polypeptide addition of amino acids between LFY of the skein LFY in epitope II. The above are directed to attenuating or disabling the interference effect of HCV-E2 epitope II.
In additional embodiments, the invention is directed to use of epitope II as a molecular decoyant. In further embodiments, the invention is directed to use of epitope II to affinity purify an immune globulin to deplete interfering antibodies from and enrich neutralizing antibodies in the preparation.
Applications: Antiviral; Hepatitis C Virus (HCV) therapy.

Treatment of Skin Conditions Using DKK1
Description of Technology: This invention discloses a method for inducing non-palmoplantar skin (skin of the trunk, arms, and face etc.) to develop characteristics of palmoplantar skin (skin of the soles and palms). This effect is achieved by use of Dickkopf 1 (DKK1), a protein which is highly expressed by palmoplantar fibroblasts and is a known antagonist of the Wnt signaling pathway. Topical application of DKK1 to non-palmoplantar skin induces the development of increased skin thickness, decreased pigmentation, and decreased hair growth. These characteristics are desirable for treating several dermatological conditions.
The skin thickening caused by topical application of DKK1 can be useful for skin grafts, and skin ulcers or abrasions. Decreased skin pigmentation, experimentally achieved by either topical or in vitro application of DKK1, may be desirable for conditions such as uneven skin pigmentation, pigmented birthmarks, or post inflammatory pigmentation. Suppressed hair growth may be cosmetically desirable for some areas of the skin, and in conditions such hypertrichosis, adrenal hyperplasia, or polycystic ovarian syndrome. DKK1 treatment may also be important for treating or preventing certain melanomas which involve hyperplastic or pre-malignant lesions.
Applications: Useful for skin grafts, skin ulcers, skin abrasions, fragrance dermatitis, vitiligo, etc.; Treatment of several conditions which require decreased skin pigmentation; Decreased hair growth for cosmetic or therapeutic purposes.
Development Status: Early stage.

Flow-Through Thermal-Expansion-Compensated Microcells for Analytical Transmission Infrared Spectroscopy
Description of Technology: Available for licensing and commercial distribution are optical cells spectroscopically stable and can be used for spectroscopic measurement in transmission, sample reflection, back plate reflection, emission, or scattering modes. The cell allows fluid in a sample space to be exchanged without separating a front or a back plate from a spacer, allows a solid sample to be placed in or removed from the sample space, requires only a small amount of sample, and allows for different sample gaps to be easily and inexpensively set. Alternatively, the spacers can be manufactured using a hydrocarbon-resistant polymer so that samples dissolved in organic solvents can be used without the risk of changing the spectral properties of the microcell and solvent leakage from the sample space. The inventive cell and methods allow spectral measurements to be taken over wavelengths ranging at least from the mid-infrared to the vacuum ultraviolet, provide a simple path for light traveling through a sample, and allow fast kinetic processes to be detected and monitored reproducibly and sensitively.Start Printed Page 40587

Rapid and Sensitive Detection of Nucleic Acid Sequence Variations
Description of Technology: The ability to easily detect small mutations in nucleic acids, such as single base substitutions, can provide a powerful tool for use in cancer detection, perinatal screens for inherited diseases, and analysis of genetic polymorphisms such as genetic mapping or for identification purposes. Current approaches make use of the mismatch that occurs between complimentary strands of DNA when there is a genetic mutation, the electrophoretic mobility differences caused by small sequence changes, and chemicals or enzymes that can cleave heteroduplex sites. Some of these methods, however, prove to be too cumbersome, are unable to pinpoint mutations, only detect a subset of mutations, or involve the use of hazardous materials.
The current invention takes advantage of the ability of transposons, or mobile genetic elements, to move from one part of the genome to another by the cleavage and joining of their sequences into the target site; a reaction facilitated by a transposase enzyme. The phage Mu transposase is capable of inserting the right end sequence of the Mu transposon into any DNA sequence both in vitro and in vivo. The surprising discovery that the Mu transposase displays a strong preference for inserting Mu-end DNA into mismatched sites, the very sites which occur when DNA is mutated and paired with its complementary strand that does not have the corresponding mutation, makes it a powerful tool for detecting variations in nucleic acid sequences. In this system, the transposition of Mu-end DNA at a site is used to indicate the presence of a nucleic acid mismatch or mutation at that site. The invention can be used with labeled Mu-end DNA to further facilitate the precise mapping of the mutations. This specificity allows Mu to detect even single base mutations among a large quantity of non-specific DNA. The Mu detection system is simple, rapid, and highly sensitive compared to current methods and can find a broad range of use in genetic research and the diagnosis of several diseases such as cystic fibrosis, spinal and bulbar muscular dystrophy, human fragile-X syndrome, and Huntington's disease.
