  • Patent number: 6191112
    Abstract: Disclosed are methods for treatment of humans exposed to bacterial endotoxin in circulation by administration of bactericidal/permeability-increasing (BPI) protein products. Serologically and hematologically verifiable alleviation of endotoxin mediated increases in circulating cytokines, fibrinolysis and coagulation factors and changes in lymphocyte counts are observed upon such treatment. Also observed is alleviation of endotoxin mediated decreases in systemic vascular resistance index (SVRI) and concomitant increases in cardiac index (CI).

  • Patent number: 6146631
    Abstract: The present invention provides purified and isolated polynucleotides encoding Type I ribosome-inactivating proteins (RIPS) and analogs of the RIPs having a cysteine available for disulfide bonding to targeting molecules. Vectors comprising the polynucleotides and host cells transformed with the vectors are also provided. The RIPs and RIP analogs are particularly suited for use as components of cytotoxic therapeutic agents of the invention which include gene fusion products and immunoconjugates. Cytotoxic therapeutic agents or immunotoxins according to the present invention may be used to selectively eliminate any cell type to which the RIP component is targeted by the specific binding capacity of the second component of the agent, and are suited for treatment of diseases where the elimination of a particular cell type is a goal, such as autoimmune disease, cancer and graft-versus-host disease.
