  • Patent number: 6524807
    Abstract: Modified forms of human interleukin-1&bgr; converting enzyme (ICE) that display proteolytic activity and, furthermore, have increased stability compared to unmodified human ICE are disclosed. Nucleic acid molecules encoding a modified p10 subunit of ICE, and recombinant vectors and host cells incorporating such nucleic acid molecules, are also disclosed. A modified ICE protein of the invention can be used to cleave proteolytically ICE substrates and to identify modulators of ICE activity in screening assays. Moreover, due to its enhanced stability, the modified ICE of the invention is particularly suitable for use in the preparation of ICE crystals for X-ray crystallography.

  • Patent number: 6509015
    Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor &agr; (hTNF&agr;) are disclosed. These antibodies have high affinity for hTNF&agr; (e.g., Kd=10−8 M or less), a slow off rate for hTNF&agr; dissociation (e.g., Koff=10−3 sec−1 or less) and neutralize hTNF&agr; activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNF&agr; and for inhibiting hTNF&agr; activity, e.g., in a human subject suffering from a disorder in which hTNF&agr; activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.

  • Patent number: 6504008
    Abstract: The present invention makes available a rapid, reproducible, robust assay system for screening and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular protein, e.g., a receptor or ion channel. The subject assay enables rapid screening of large numbers of compounds to identify those which act as an agonist or antagonist to the bioactivity of the cellular protein. In particular, the assay of the invention makes use of a cell that harbors a protein that is responsive to a cellular signal transduction pathway. The protein is operatively linked to a polypeptide which causes a detectable signal to be generated upon stimulation of the pathway, e.g., when a compound interacts with and modulates the activity of a cellular receptor or ion channel of the cell.

  • Patent number: 6491912
    Abstract: Porcine cardiomyocytes and methods for using the cardiomyocytes to treat disorders characterized by insufficient cardiac function are described. The porcine cardiomyocytes are preferably embryonic porcine cardiomyocytes. The porcine cardiomyocytes can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine cardiomyocytes can be modified such that an antigen (e.g., an MHC class I antigen) on the cardiomyocyte surface which is capable of stimulating an immune response against the cardiomyocytes in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cardiomyocyte when introduced into the subject. In one embodiment, the porcine cardiomyocytes are obtained from a pig which is essentially free from organisms or substances which are capable of transmitting infection or disease to the recipient subject.

  • Patent number: 6445941
    Abstract: A novel method and apparatus for obtaining the electrocardiogram (ECG) in small conscious animals, such as mice, without the need to anesthetize or instrument the animal, are described. The apparatus includes an array of conductive pads, embedded in a platform, the pads sized and spaced to advance contact between an animal's paws and the pads as the animal freely moves upon the platform. Electrical circuitry to the pads is configured to sense the parings of pads and paws that render an interpretable ECG signal and to activate or deactivate recording of the signals. The apparatus is suspended above a surface to minimize the range of motion of the animal without physical restraint.

  • Patent number: 6444205
    Abstract: Methods for using neural cells to treat chronic pain and/or spasticity are described. The neural cells can be derived from any mammal, and are preferably human or porcine in origin. The neural cells preferably are serotonergic cells or are gamma-aminobutryic acid (GABA)—producing cells. Neural cells can be obtained from adult, juvenile, embryonic or fetal donors. Neural cells can be modified to be suitable for transplantation into a subject. For example, the neural cells can be modified such that an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject or can be genetically modified to produce a factor.

  • Patent number: 6416948
    Abstract: The invention provides methods for the identification of members of a malignant lymphocyte clone by analysis of clonotypic DNA rearrangements of T cell or B cell receptor genes. The DNA or RNA from isolated single tumor cells is amplified by PCR using consensus primers to the VDJ region of the receptor genes, and the sequence of the VDJ region is obtained from each. The clonotypic sequence of the malignant clone is identified as the most frequent VDJ sequence amplified. Individual-specific PCR primers for the VDJ region are then designed based upon the clonotypic sequence. These specific PCR primers are used to detect and quantitate clonotypic cells in subsequent patient samples using in situ PCR or in situ RT-PCR. Fractionated or unfractionated samples of blood or bone marrow, as well as tissue sections can be analyzed.
