The present disclosure relates to the composition of one or more agents, therapies, treatments, and methods of use of the agents and/or therapies and/or treatments for upregulating production of two or more antibodies, one or more bi-specific antibodies, or combinations thereof. Embodiments of the present disclosure can be used as a therapy or a treatment of a conditions including: sepsis, parasites, and active and chronic infections caused by bacteria, non-hemorrhagic viruses, amoeba, mycoplasma, fungus, prions or combinations thereof.

The present invention, in at least some embodiments, is of a system, method, apparatus and diagnostic test for monitoring infections by Plasmodium falciparum that is specific for pregnant women. The monitoring is performed by examining samples from the pregnant women, typically blood samples, for the presence of antibodies to a known P. falciparum protein, VAR2CSA. Preferably, the antibodies bind specifically to p5 and/or p8.

Described herein are binding proteins that specifically bind to human CD33, and in particular to bispecific binding proteins that specifically bind to human CD33 and human CD3. Also described herein are bispecific tandem diabodies that bind to CD33 and CD33, and their uses for immunotherapy of CD33.sup.+ cancers, diseases and conditions such as acute myeloid leukemia (AML).

The present invention relates to a vaccine V comprising (A) at least one isolated polypeptide strand P comprising or consisting of at least nine consecutive amino acid moieties of the repetitive organellar protein, putative of Plasmodium falciparum or the hypothetical protein PVNG_04523 of Plasmodium vivax or a polynucleotide strand encoding for such polypeptide; and (B) at least one pharmaceutically acceptable carrier or excipient. Furthermore, the present invention refers to an antibody binding to the repetitive organellar protein,putative of Plasmodium falciparumor the hypothetical protein PVNG_04523 of Plasmodium vivax or a polynucleotide strand encoding therefor, to a method of generating such antibody and uses thereof.

The present invention provides a fragment of plasmodium circumsporozoite protein according to SEQ ID NO: 1, for example for use in a malaria vaccine. The present invention also provides nucleic acids encoding a fragment of plasmodium circumsporozoite protein according to SEQ ID NO: 1, compositions comprising a fragment of plasmodium circumsporozoite protein according to SEQ ID NO: 1 and antibodies binding to a fragment of plasmodium circumsporozoite protein according to SEQ ID NO: 1. The antibodies according to the present invention bind specifically to P. falciparum sporozoites and may be used in the treatment and/or prevention of malaria.

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.

The present description relates to malaria vaccines comprising Plasmodium falciparum (Pf) polypeptide complexes and methods of producing the same. The Pf polypeptides in complexes or in a partially complexed arrangement may comprise two or more of the following polypeptides: PfRipr, PfCyrPa and PfRh5. Drosophila cells and expression vectors are also described.

The invention provides compositions and methods for preventing or reducing the severity of malaria.

The present invention provides CD20-binding proteins that bind to and rapidly internalize CD20 antigens from a cell surface location to the interior of a cell. CD20-binding proteins of the invention comprise a CD20 binding region and a Shiga toxin effector region. Certain of the disclosed CD20-binding proteins kill cells that express CD20 on their surface. Further, the presently disclosed CD20-binding proteins can comprise additional exogenous materials and are capable of targeted delivery of these additional exogenous materials into the interior of CD20 expressing cells. Such additional materials may include peptides, antigens, enzymes, and polynucleotides. These CD20-binding proteins have uses in methods of internalizing themselves, targeted killing of CD20 expressing cells, delivering exogenous materials into CD20 expressing cells, and treating a variety of diseases involving CD20 expressing cells, such as cancers and immune disorders.
