The technology provided herein relates to novel human antibodies against Plasmodium parasites, in particular against the malaria parasite Plasmodium falciparum. The present disclosure pertains to antibodies against apical membrane antigen 1 (AMA-1). These antibodies have high affinity e.g. to Plasmodium falciparum schizonts and merozoites, inhibit the reinvasion of merozoites into erythrocytes and thereby neutralize parasitic multiplication.

Complexes suitable for targeting and killing a human target cell comprising a first polypeptide with a binding structure for binding the complex to the cellular surface receptor CD89 (e.g. with an anti CD89 antibody) presented on the cell surface of the human target cell and a second polypeptide comprising a toxic effector domain, preferably Pseudomonas exotoxin A); to nucleic acid molecules encoding said complexes, vectors, host cells containing the nucleic acids and methods for preparation and producing such complexes; compositions and methods for using said complexes for the treatment of diseases, in particular of cancer diseases like leukemia.
摘要:
To provide a series of techniques capable of producing isoprene from syngas or the like. Provided is a recombinant cell prepared by introducing a nucleic acid encoding isoprene synthase into a host cell having an isopentenyl diphosphate synthesis ability by a non-mevalonate pathway, wherein the nucleic acid is expressed in the host cell, and the recombinant cell is capable of producing isoprene from at least one C1 compound selected from the group consisting of carbon monoxide, carbon dioxide, formic acid, and methanol. As the host cell, a Clostridium bacterium or a Moorella bacterium is exemplified. Also provided is a method for producing isoprene using the recombinant cell.
摘要:
The invention relates to an artificial forisome body which comprises a fusion protein consisting of at least one SEO-F protein or a section thereof that comprises at least 50 amino acids, and at least one additional protein or peptide with the exception of the GFP and Venus proteins, in which (a) said additional protein or peptide has a mass of no more than 30 kDa, and/or (b) the forisome body also comprises a non-fusion SEO-F protein or a form of this protein that is C-terminally deleted by up to 45 amino acids and/or N-terminally deleted by up to 13 amino acids, the non-fusion SEO-F protein being selected from those proteins which have the property of being able to form homomeric forisome bodies in the absence of additional SEO-F proteins, or (c) the additional protein or peptide is a section of a second SEO-F protein provided that one of the two SEO-F proteins, in a non-fusion form, is capable of forming homomeric forisome bodies, and the fusion protein consists of an N-terminal SEO-F protein section and a C-terminal SEO-F protein section, said sections constituting an SEO-F protein that is complete or C-terminally deleted by up to 50 amino acids and/or N-terminally deleted by up to 13 amino acids, provided that, if required, any number of the four cysteines present in the native SEO-F proteins in the C-terminal section between AS 600 and AS 670 may be exchanged for amino acids that are unable to form an S-S bridge bond. The invention also relates to a plant cell or yeast cell comprising a vector that codes for the given fusion protein and, if required, also for the non-fusion SEO-F protein or its deleted form as defined in (b), as well as to a vector that can be multiplied in a yeast cell and that comprises a section which codes for the given fusion protein. The artificial forisome body of the invention is suitable for protein-chemical purposes, in particular for providing immobilised enzymes, antibodies, antigens and such proteins or peptides that can be immobilised, on a substrate, on the basis of an affinity reaction with a substrate-bound biological or biochemically-produced material.

A method is disclosed permitting the determination of comprehensive immunoglobulin-specific reaction profiles of people with immuno-functional disorders by means of the individual V gene repertory of Ig-expressing B-cells. The method comprises the isolation of B-cells from body fluids, the isolation of individual B-cells and the genetic material thereof, the amplification of nucleic acids, coding for the variable regions of an antibody expressed by a B-cell, the recombinant production of antibodies by expression of the amplified material and the determination of the binding of the recombinant antibody to antigens.
