Purified recombinant polypeptides isolated from Chinese hamster ovary host cells, including antibodies, such as therapeutic antibodies, and methods of making and using such polypeptides are provided.

The invention relates to neutralizing antibodies, and antibody fragments thereof, having high potency in neutralizing hCMV, wherein said antibodies and antibody fragments are specific for one, or a combination of two or more, hCMV gene UL products. The invention also relates to immortalized B cells that produce, and to epitopes that bind to, such antibodies and antibody fragments. In addition, the invention relates to the use of the antibodies, antibody fragments, and epitopes in screening methods as well as in the diagnosis, prevention, and therapy of disease.

The invention relates to a novel class of antagonistic and inverse agonistic anti-US28 antibodies, more specifically to single heavy chain variable domain antibodies (VHH) and variants and modifications thereof. The invention further relates to methods for producing these antibodies and to the use of the antibodies in methods for diagnostic and therapeutic purposes, especially for treatment of an individual suffering from a CMV-positive tumor such as glioblastoma.

The present invention provides protease-cleavage resistant molecules comprising Shiga toxin effector polypeptides capable of exhibiting potent, Shiga toxin functions (e.g. subcellular routing and cytotoxicity). The present invention also provides protease-cleavage resistant, cell-targeting molecules for targeting specific cell types, e.g., infected or malignant cells. Certain molecules of the present invention are cytotoxic, and certain cell-targeting molecules of the present invention may be used for the targeted killing of specific cell types and the treatment of a variety of diseases, disorders, and conditions, including cancers, tumors, growth abnormalities, immune disorders, and microbial infections. Certain cell-targeting molecules of the invention exhibit improved, in vivo tolerability as compared to related cell-targeting molecules comprising protease-cleavage sensitive, wild-type, Shiga toxin effector polypeptides. The cell-targeting molecules of the invention can deliver additional materials, such as, e.g., antigens, cytotoxic agents, and detection-promoting agents, into the interiors of target cells.

Methods for treating or reducing the risk of a cytomegalovirus infection in a subject that include administering one or more of an inhibitor of Deleted in Malignant Brain Tumors 1 (DMBT1), an inhibitor of OR14I1, or an inhibitor of adenylyl cyclases.

A method of use of plasma immunoglobulin, such as intramuscular immunoglobulin, in combination with polyclonal antigen-specific immunoglobulin in the treatment or prevention of allergic disease is provided. Also provided is a pharmaceutical composition including plasma immunoglobulin in combination with polyclonal antigen-specific immunoglobulin.
