45 results about "Cartilage degradation" patented technology

Cartilage degradation is attributed to different classes of catabolic factors, including proinflammatory cytokines, aggrecanases, matrix metalloproteinases, and nitric oxide. Recently, matrix degradation products generated by excessive proteolysis in arthritis have been found to mediate cartilage destruction.

Viral vectors to inhibit leukocyte infiltration or cartilage degradation of joints

Methods for treating a connective tissue disorder by introducing at least one gene encoding a product into at least one target cell of a mammalian host for use in treating the mammalian host are disclosed. These methods include employing recombinant techniques to produce a vector molecule containing the DNA sequence encoding for the product and infecting the target cell of the mammalian host using the vector. The injection can be done in vivo, by directly injecting the vector into the host, or can be done in vitro by transfecting a population of cultured target cells with the vector and transplanting them each into the host. Nonviral means can also be used to introduce the DNA sequence to the host. Administration of more than one gene of interest results in an enhanced therapeutic benefit. Also disclosed is a method for treating a connective tissue disorder by introducing at least one gene encoding a product into at least one target cell of a joint of a host for use in treating multiple joints of the host. Injection of a vector molecule containing the DNA sequence encoding for a product of interest, or non-viral introduction of such a DNA sequence, to one join of a mammalian host results in a therapeutic benefit in that joint as well as other joints in the host
