Abstract: The present invention relates to novel immunoconjugates that are devoid of light chains and comprise at least one variable domain of a heavy chain antibody. The immunoconjugates of the present invention can be used, for example, for the preparation of a medicament to treat tumors.

Abstract: The present invention is based on the finding that peptides derived from a specific domain of tumor necrosis factor-alpha (TNF-&agr;) can efficiently be used to treat oedema. More specifically, the present invention relates to the usage of peptides derived from the region of human TNF-&agr; from Ser100 to Glu116 to treat pulmonary oedema. For example, the circularized peptide having amino acid sequence CGQRETPEGAEAKPWYC is shown to be very efficient in inducing oedema resorption.

Abstract: The present invention relates to the use of the major OprI lipoprotein of Pseudomonas aeruginosa to elicit a Type-1 immune response towards a heterologous antigen. The invention relates specifically to the use of OprI—antigen fusion proteins to elicit the Type-1 response. More particularly, the present invention is directed to pharmaceutical formulations comprising OprI and/or OprI fusion proteins, optionally together with a suitable excipient, to stimulate the Th1 dependent, cellular immune response.

Abstract: The invention relates to tumor necrosis factor muteins characterized in that the TNF-.alpha. amino acid sequence is mutated, or deleted totally or partially, in the region containing position 101 to 116 in such a way that:either the lectin-like activity is reduced with respect to TNF-.alpha.,or the toxic activity is reduced with respect to TNF-.alpha.; and providing that said muteins have largely retained the tumoricidal activity of TNF-.alpha.; and with said muteins possibly containing in their peptidic chain additional modifications consisting of substitutions and/or deletions and/or additions of one or several amino acid residues, and with said muteins being characterized in that they have retained the aforementioned activities; or a pharmaceutically acceptable salt thereof.

Abstract: The property of phagocyte cells to show chemiluminescence when activated by certain chemical or immunological agents is used for a qualitative and quantitative analysis of such agents in biological fluids. A variety of factors such as opsonizing anti-bodies, complement, inhibitors, membrane-specific anti-bodies, and their antigens, membrane-specific lectins, lymphokines, endotoxins, toxic substances and others can be analyzed in this way. The new method finds application in the biotechnical, clinical, immunological and pharmacological fields, with a special preference for toxicological screening of pharmaceuticals. The phagocyte cells needed for the analysis can be derived from a continuous phagocyte cell line and a method of producing such a cell line is provided.
