The present invention provides compositions of CD180 targeting molecules coupled to heterologous antigens, and their use in treating and/or limiting disease.

This disclosure is directed to methods of preparing dendritic cells or other CD40 bearing antigen-presenting cells and methods of treating an infectious disease by using the dendritic cells or other antigen-presenting cells in combination with anti-chemorepellant agents. This disclosure is further directed to methods of preparing T cells and methods of treating an infectious disease by using activated T cells optionally in combination with anti-chemorepellant agents. The antigen presenting cells of the disclosure are activated by incubation with a pathogen or pathogen-infected cells and fusion proteins. The T cells of the disclosures are activated by incubation with activated antigen-presenting cells that were activated by incubation with a pathogen or pathogen-infected cells and a fusion protein. In particular, the fusion protein comprises an antigen-binding domain, e.g., an antibody or antibody fragment, and a stress protein domain.

The present invention relates to a delivery system suitable for delivering a substance into a XCR1 positive professional antigen-presenting cell, one or more nucleic acids coding for the same, a vector comprising the nucleic acid(s), a medicament comprising the delivery system or the one or more nucleic acid(s) and an adjuvant comprising XCL1 or a functionally active fragment thereof.

Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include one or more RNA polynucleotides having an open reading frame encoding one or more Chikungunya antigen(s), one or more Zika virus antigens, and one or more Dengue antigens. Methods for preparing and using such vaccines are also described.

The present invention includes compositions and methods for the expression, secretion and use of novel compositions for use as, e.g., vaccine and antigen delivery vectors, to delivery antigens to antigen presenting cells. In one embodiment, the vector is an anti-CD40 antibody, or fragments thereof, and one or more antigenic peptides linked to the anti-CD40 antibody or fragments thereof, including humanized antibodies.

Provided is an application of a plant as a host in expressing a vaccine of Middle East respiratory syndrome. In particular, lettuce is utilized to transiently express fusion proteins to prepare a vaccine for Middle East respiratory syndrome.

This invention relates to antibody-albumin nanoparticle complexes comprising albumin, an antibody with binding specificity for a cancer antigen (e.g. panitumumab), and paclitaxel, wherein the nanoparticle complex has been pre-formed in vitro such that the nanoparticle complex has antigen-binding specificity (e.g. EGFR binding specificity), for the purpose of providing cancer (e.g. EGFR-related cancer) treatments in a subject in need thereof.

Herein is reported a conjugate comprising an antigen and an antibody that specifically binds to the antigen wherein a covalent bond is formed between the antigen and an amino acid residue in the CDR2 of the antibody, an antibody comprising a cysteine residue at amino acid position 53 (according to Kabat) in the heavy chain CDR2 and uses thereof.

The present invention relates to methods and pharmaceutical compositions of inducing immune tolerance by mucosal vaccination with Fc-coupled antigens. In particular, the present invention relates to a method for inducing tolerance to one antigen of interest in a subject in need thereof, comprising the mucosal administration to the subject of a therapeutically effective amount of a recombinant chimeric construct comprising a FcRn targeting moiety and an antigen-containing moiety.

The present invention relates to a fusion protein for cancer treatment and a use thereof.

The fusion protein for preventing or treating cancer of the present invention comprises a fusion polypeptide comprising: an antibody or fragment thereof binding to a tumor-associated antigen; a linker; and a NK cell-inducing protein of CXCL16, wherein a co-administration of the fusion polypeptide along with the NK cells, an immunocyte therapeutic agent, greatly increases an influx of the NK cells into cancer expressing a certain antigen, thereby having a remarkable effect on preventing or treating cancer.
