Disclosed herein are cytomegalovirus vectors encoding fusion proteins comprising Mycobacterium tuberculosis (Mtb) antigens, nucleic acid molecules encoding the same, cytomegalovirus vectors comprising nucleic acid molecules, compositions comprising the same, and methods of eliciting an immune response against tuberculosis.

The present disclosure relates to recombinant rhesus cytomegalovirus (RhCMV) and human cytomegalovirus (HCMV) vectors encoding heterologous antigens, such as pathogen-specific antigens or tumor antigens, which may be used, for example, for the treatment or prevention of infectious disease or cancer. The recombinant RhCMV or HCMV vectors elicit and maintain high level cellular immune responses specific for the heterologous antigen while including deletions in one or more genes essential or augmenting for CMV replication, dissemination or spread.

Aspects of the disclosure relate to methods for producing an antigen-specific immune response to human cytomegalovirus (hCMV) in a subject by administering mRNA vaccines.

The present disclosure provides cytomegalovirus vectors encoding fusion proteins comprising Mycobacterium tuberculosis (Mtb) antigens, nucleic acid molecules encoding the same, cytomegalovirus vectors comprising nucleic acid molecules, compositions comprising the same, and methods of eliciting an immune response against tuberculosis.

The invention is directed to multivalent HCMV immunogenic compositions and their use.

Provided are antigenic compositions and uses thereof that include at least two human herpesvirus (HHV) polypeptides involved in mediating HHV binding, fusion, and entry into host cells, such as gp350, gH, gL, and gB, or nucleic acids encoding the polypeptides. The two HHV polypeptides comprise any combination of: a gB polypeptide; a gp350 polypeptide; a gL polypeptide; and a gH polypeptide, and optionally any one or more of the following polypeptides: gp42, gM, gN, gl, gC, gE, gD, ORF68, BMRF-2, BDLF2, UL128, UL130, UL131A, and gpK8.1. Also disclosed are methods of inducing an immune response or treating or preventing an HHV infection in a subject by administering to the subject at least two of the HHV polypeptides or nucleic acid(s) encoding the same. Methods of passively transferring immunity using high-titer anti-HHV antibodies or immune cells are also disclosed.

The present disclosure is in the field of genome engineering, particularly targeted integration of a functional SCID-related genes (e.g., IL2RG, RAG1 and/or RAG2 gene) into an IL2RG gene of a cell for provision of proteins lacking or deficient in SCID.

In one aspect, the present invention provides recombinant polynucleotides. In some embodiments, the recombinant polynucleotides comprise a cytomegalovirus (CMV) genome, or a portion thereof, and a nucleic acid sequence encoding an antigen, wherein the CMV genome or portion thereof comprises a mutation within a interleukin-10-like gene sequence. Methods for preventing and treating diseases such as infectious diseases and cancer are also provided herein.

The present disclosure provides compositions and methods useful for treating Glioblastoma Multiforme (GBM), e.g., compositions comprising virus-like particles (VLPs) comprising Moloney Murine leukemia virus (MMLV) core proteins and the human cytomegalovirus epitopes, gB and pp65, formulated with GM-CSF, which, at dose of at least 10 g gB/pp65Gag, reverse dysregulation of anti-HCMV immunity in GBM patients.

The disclosure relates to HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.
