摘要:
A monoclonal or polyclonal antibody directed against urokinase plasminogen activator receptor (u-PAR), or a subsequence, analogue or glycosylation variant thereof. Antibodies are disclosed which react with free u-PAR or with complexes between u-PA and u-PAR and which are capable of 1) catching u-PAR in ELISA, or 2) detecting u-PAR, e.g. in blotting, or 3) in radioimmunoprecipitation assay precipitate purified u-PAR in intact or fragment form, or 4) is useful for immunohistochemical detection of u-PAR, e.g. in immunostaining of cancer cells, such as in tissue sections at the invasive front, or 5) inhibits the binding of pro-u-PA and active u-PA and thereby inhibits cell surface plasminogen activation. Methods are disclosed 1) for detecting or quantifying u-PAR, 2) for targeting a diagnostic to a cell containing a u-PAR on the surface, 3) for preventing or counteracting proteolytic activity in a mammal. Methods for for selecting a substance suitable for inhibiting u-PA/u-PAR interaction, for preventing or counteracting localized proteolytical activity in a mammal, for inhibiting the invasion and/or metastasis comprise the use of the antibodies and of nude mice inoculated with human cancer cells which are known to invade and/or metastasize in mice and having a distinct color, f.x. obtained by means of an enzyme and a chromogenic substrate for the enzyme, the color being different from the cells of the mouse.
摘要:
Activation of plasminogen to plasma is inhibited by preventing the binding of a receptor binding form of urokinase-type plasminogen activator to a urokinase-type plasminogen activator receptor in a mammal, thereby preventing the urokinase-type plasminogen activator from converting plasminogen into plasmin. DNA fragments which encode for soluble, active fragments of the urokinase-type plasminogen activator are provided.

摘要:
The present invention relates to methods for inhibiting malignant tumour growth, invasion and/or metastasis in a patient, the method comprising suppressing the inhibitory activity of an inhibitor of a protease or of a non-proteolytic matrix-degrading enzyme (IPNME) in malignant tumour tissue or potential malignant tumour tissue. The suppression may be brought about by administering compounds interacting with the IPNME, but also administration of compounds interacting with transcription of genes encoding the IPNME is a possibility. The invention also relates to methods of selecting and identifying compounds in the therapeutical methods, as well of the use of such compounds in the treatment of malignancies.

The invention relates to the field of recombinant antibodies for use in human cancer therapy. More specifically the invention provides compositions or mixtures of antibodies capable of binding human EGFR. Antibody compositions with 3 or more antibodies showed synergy in reduction of proliferation of representative cancer cell lines. Advantageous results have also been obtained with a composition comprising two different chimeric anti-hEGFR antibodies which show a new mechanism of action based on rapid and efficient receptor internalisation, induction of terminal differentiation and subsequent tumour eradication in an animal model. The antibodies of the invention can be manufactured in one bioreactor as a polyclonal antibody.

The invention relates to a procedure for linking cognate pairs of VH and VL encoding sequences from a population of avian cells enriched in particular surface antigen markers. The linking procedure involves a multiplex molecular amplification procedure capable of linking nucleotide sequences of interest in connection with the amplification (multiplex PCR). The method is particularly advantageous for the generation of cognate pair libraries as well as combinatorial libraries of antibody variable region encoding sequences from chickens or other birds. The invention also provides methods for generation of chimeric human/avian antibodies and expression libraries generated by such methods.

The present invention relates to the field of compositions comprising anti-CD5 antibodies. In particular, the present invention concerns an antibody composition comprising at least two anti-CD5 antibodies capable of binding distinct CD5 epitopes. The invention further concerns bi-specific molecules having the binding specificities of said antibody compositions. The invention also relates topharmaceutical compositions, use of antibody compositions and methods for manufacturing antibody compositions. The invention further relates to cell banks and a method for killing cells.
