Abstract:
Substituted pyrazoles, imidazoles, triazoles, other 5-membered heteroaromatic ring compounds, substituted 6-membered heteroaromatic ring compounds, and fluorene and carbazole compounds, may be included in pharmaceutical central nervous system drug compositions to treat a condition mediated by an opioid receptor in a patient. Such compounds are designed to possess improved transport across the blood-brain barrier. These compounds possess an optimal combination of high lipophilicity, low polarity, limited conformational flexibility, and few hydrogen bonding groups. Such lipophilic opioid receptor active compounds are useful for treating pain, inflammation, arthritis, central nervous system disorders, and other diseases.
Abstract:
[00243] Described are compositions and methods useful for modulating the immune system of a subject. Also included are diagnostic methods for monitoring an immunologic condition. In particular the invention relates to antagonists of interferon proteins and associated methods of use as well as methods to develop neutralizing antibodies against IFN antagonists to treat viral infections.
Abstract:
The invention provides methods for identifying an agent which prevents or partially prevents an antitoxin from forming a complex with its cognate toxin, comprising contacting a potential agent with a labeled substrate in solution, whereby detection of the label indicates presence of an agent that prevents an antitoxin from forming complex with a toxin. The invention also provides agents capable of interfering with formation of a toxin-antitoxin complex. Such agents act as novel, non-conventional antibiotics against human pathogenic bacteria.
Abstract:
A composition comprising leukotoxin proteins isolated from a bacterium is provided. In this composition, greater than 85% of the leukotoxin proteins are chemically modified at a basic amino acid residue, and the proteins induce cell death in myeloid leukocytes, while remaining substantially non-toxic to lymphoid leukocytes, lymphocytes, and red blood cells. Also provided is a method of selectively inducing cell death in myeloid leukocytes. The method comprises contacting the myeloid leukocytes with a composition comprising leukotoxin proteins. These leukotoxin proteins may be isolated from the NJ4500 strain of Actinobacillus actinomycetemcomitans. A method of purifying leukotoxin protein from the NJ4500 strain of Actinobacillus actinomycetemcomitans is also provided.
Abstract:
Methods of inhibiting annexin 1 induced apoptosis by contacting a cell population containing a TRPM7/ChaK1 kinase with an effective amount of a composition containing an inhibitor for the kinase.
Abstract:
Isolated nucleic acid sequences and amino acid sequences for soluble, β-N-acetylglucosaminidase or active fragments or variants thereof which promote detachment of bacterial cells from a biofilm are provided. An isolated mutant bacteria which forms biofilm colonies which tightly adhere to surface but which are unable to release cells into the medium or spread over the surface is also provided. In additions, methods are described for modulating detachment of bacterial cells from biofilm by mutating soluble,β-N-acetylglucosaminidase or altering its expression or activity are also provided. Also provided are compositions, methods and devices for preventing, inhibiting and treating bacterial infections.
Abstract:
The present invention relates to a method of modulating synaptic growth or plasticity by increasing the expression of genes found to be induced by BNDF. Such genes include c-fos proto-oncogene, early growth response protein 1, activity-regulated cytoskeletal associated, fos-related antigen 2, G1/S-specific cyclin D1, voltagegated potassium channel protein, sodium channel beta 1 subunit, secretogranin II precursor, somatostatin receptor 4, transmembrane receptor UNC5 homology, neuropeptide Y, VGF protein precursor and protein-tyrosine phosphatase 1B. Methods of identifying agents which modulate the expression of these genes and the use of such agents for treating a disease or condition associated with damaged or diseased synapses are also provided.
Abstract:
Variants of the HIV-1 Tat protein exhibiting higher transcriptional activation and stronger P-TEFb binding than wild-type Tat are provided. In addition variants that can inhibit transcription activation by wild-type Tat are provided. Nucleic acid sequences encoding these variants, vectors and host cells for expression of these variants, and antibodies raised against these variants are also provided. In addition, methods for use of these variants and compositions containing these variants as research tools, as diagnostic tools and in the treatment of viral infections are provided.
Abstract:
The present invention relates to a method of manufacturing and using heat shock proteins containing a step of initiating a coagulative necrotic process in a tissue. In particular, a method of manufacturing and using heat shock proteins comprises the steps of heating a tissue to initiate the coagulative necrotic process for a period of time, cooling the tissue, incubating the tissue in an appropriate growth medium, and collecting the supernatant from the tissue. In a preferred embodiment, the coagulative necrotic process is initiated by heating the tissue to 60°; or more. The tissue is then cooled to room temperature before incubating the tissue in growth media for 48 hours or less. Heat shock proteins produced in accordance with this method may be complexed to peptides or antigens to produce autologous vaccines in the prevention and treatment of various diseases. Furthermore, heat shock proteins may be used in diagnostic assays for various autoimmune and inflammatory diseases. Heat shock proteins produced in accordance with this method may also be used to quantify antibody levels that serve as disease markers.
Abstract:
Methods and kits are provided for assessing the ovarian reserve and predicting the ovarian response to fertility treatments in a female subject. The serum levels of MIS are shown to be positively correlated with the production and retrieval of mature oocytes and serve as prognostic indicators for the female reponse to fertility treatment. The MIS levels can be monitored prior to and during fertility treatment and are useful to adjust the timing and dosage of treatments in order to produce optimal outcome in individual patients, to avoid ovarian hyperstimulation, or to indicate cancellation of an unsuccessful treatment. MIS can also be administered to women to stimulate follicle development and to prevent depletion of ovarian reserve.
