The present invention relates to targeted prevention of vertical transmission of infection between mother and foetus. More particularly, the invention relates to methods of preventing neonatal Fc receptor (FcRn)-mediated transmission of virus, preferably flavivirus, more preferably Zika virus (ZIKV), from a mother immune to a cross-reactive virus e.g. Dengue virus (DENY) to her foetus, and to reagents that block or inhibit said FcRN-mediated transmission of virus.

OX40 is a potent immune stimulating target. Provided herein are methods for the treatment of cancer patients using (3X40 agonists methods to predict clinical outcome of the treatment by correlation of the treatment and an increase in OX40-induced T cell proliferation.

Provided are compositions for increasing the half-life of a polypeptide or polypeptides in a feline and methods of their use. The compositions involve variant feline IgG Fc regions.

Mice having a restricted immunoglobulin heavy chain locus are provided, wherein the locus is characterized by a single polymorphic human V.sub.H gene segment, a plurality of human D.sub.H gene segments and a plurality of J.sub.H gene segments. Methods for making antibody sequences that bind an antigen (e.g., a viral antigen) are provided, comprising immunizing a mouse with an antigen of interest, wherein the mouse comprises a single human V.sub.H gene segment, a plurality of human D.sub.H gene segments and a plurality of J.sub.H gene segments, at the endogenous immunoglobulin heavy chain locus.

The present invention provides an anti-HPV E7 protein monoclonal antibody and the use thereof. The antibody can detect the HPV16 E7 protein with high specificity and recognize the HPV18 E7 protein, thereby it can distinguish between the cancerous cervical epithelial cells and the cervical abnormal or non-cancerous cervical epithelial cells.

The present invention relates to engineered Clostridium difficile type IV pilin (tfp) genes, type IV pilin proteins which can serve as a diagnostic marker for identification of patients infected with C. difficile, and vaccines comprising type IV pilin proteins, antigenic fragments and variants thereof for therapeutic interventions.

The present invention relates to a pharmaceutical composition for preventing and treating cancer or inflammatory disease, containing an NDRG3 expression or activity inhibitor as an active ingredient. Furthermore, the present invention relates to an NDRG3 protein-specific antibody and a use thereof. Specifically, the antibody to the NDRG3 protein is prepared, and the antibody is used to verify that NDRG3 mediated by lactate generated from a hypoxia reaction promotes cell proliferation, angiogenesis, and cytokine expression through the lactate-NDRG3-c-Raf-ERK signaling pathway, and thus the antibody binding to the epitope of the NDRG3 or a fragment of the antibody can be favorably used in the research of cancer or inflammation occurrence mechanism, the development of novel genes involved in the mechanism, and the development of therapeutic agents and new pharmaceuticals.

The present invention relates to transgenic mammals that express canine-based immunoglobulins, including transgenic rodents that express canine-based immunoglobulins for the development of canine therapeutic antibodies.

The invention refers to a non-therapeutic method for producing antigen-specific B cells by using the adoptive cell transfer of primed B cells, especially of spleen cells including B cells of a previously immunized non-human animal and by administering an antigen of interest to a naïve non-human animal.

This disclosure relates to immunogens and monoclonal antibodies useful in the identification and/or treatment of cancer cells, including those of the dog. In one example, chimeric anti-canine CD20 antibodies are provided. The antibodies can be used therapeutically to treat lymphoma in dogs.
