The invention is related to polynucleotide-based cytomegalovirus vaccines. In particular, the invention is plasmids operably encoding HCMV antigens, in which the naturally-occurring coding regions for the HCMV antigens have been modified for improved translation in human or other mammalian cells through codon optimization. HCMV antigens which are useful in the invention include, but are not limited to pp65, glycoprotein B (gB), IE1, and fragments, variants or derivatives of either of these antigens. In certain embodiments, sequences have been deleted, e.g., the Arg435-Lys438 putative kinase in pp65 and the membrane anchor and endocellular domains in gB. The invention is further directed to methods to induce an immune response to HCMV in a mammal, for example, a human, comprising delivering a plasmid encoding a codon-optimized HCMV antigen as described above. The invention is also directed to pharmaceutical compositions comprising plasmids encoding a codon-optimized HCMV antigen as described above, and further comprising adjuvants, excipients, or immune modulators.

A combination of HKI-272 compound and a vinorelbine compound in the treatment of a neoplasm is provided. Regimens, kits, and methods for treatment of neoplasm, including breast cancer including metastatic breast cancer, and lung cancer, using this combination, optionally in combination with other anti-neoplastic agents, or immune modulators are also described.

A method for the treatment of myeloma and thymoma by administering a therapeutically effective dose of Mycobacterium indicus pranii with Cyclophosphamide. This disclosure generally relates to the field of cancer biology. More specifically, this disclosure relates to the immunotherapeutic treatment of myeloma and thymoma, using a combination of heat killed Mycobacterium indicus pranii and the widely administered chemotherapeutic drug, Cyclophosphamide. Mycobacterium indicus pranii has already shown its efficacy as an immunomodulator and has been safely administered to humans. The most common method of cancer management is the application of chemotherapeutic drugs which results in side-effects. At lower non-toxic doses Cyclophosphamide is not effective. The present disclosure discloses a method of improving efficacy of non-toxic doses of Cyclophosphamide by administrating it together with Mycobacterium indicus pranii. This disclosure is relevant for the treatment of other lymphomas as well.

A preparation containing lipopolysaccharide (LPS) of Porphyromonas gingivalis having a molecular negative mass ion of 1435 or 1449 is used as an immune system modulator to redirect a host's immune system against an antigen of interest. The 1435 / 1449 LPS preparation can be isolated from P. gingivalis or prepared as a derivative or mimetic thereof. The immunomodulating preparations of P. gingivalis 1435 / 1449 can be used as a vaccine adjuvant, and can be used to stimulate an immune response against a selected antigen associated with a disease of interest, such an antigen associated with a tumor, infectious disease, autoimmune disease, MHC antigen, or to modulate asthma or other inflammatory conditions.

The present invention relates to intracellular signaling molecules, in particular the Nod2 protein and nucleic acids encoding the Nod2 protein. The present invention provides methods of identifying modulators of Nod2 signaling. In particular, the present invention additionally provides methods of screening immune modulators such as adjuvants using Nod2. The present invention further provides methods of altering Nod2 signaling.

Eliciting a systemic antitumor immune response, in a patient who presents with or who is at risk of developing multiple metastatic tumors of a given cell type, entails, in one embodiment, inoculating a tumor in the patient with a pharmaceutical composition consisting essentially of (A) a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells and (B) a pharmaceutically acceptable vehicle for the virus, such that an immune response is induced that is specific for the tumor cell type and that kills cells of the inoculated tumor and of a non-inoculated tumor. In another embodiment, the pharmaceutical composition also comprises a defective HSV vector which contains an expressible nucleotide sequence encoding at least one immune modulator. In another embodiment, the pharmaceutical composition contains a second HSV that infects tumor cells but that does not spread in normal cells. According to the latter approach, both the first HSV and the second HSV may have genomes that comprise, respectively, an expressible nucleotide sequence coding for at least one immune modulator. In another embodiment, the pharmaceutical composition comprises, in addition to a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells, a viral vector comprising at least one expressible nucleotide sequence coding for at least one immune modulator.

Disclosed are compounds based on C- and D-ring modifications of triptolide and hydroxylated triptolide, for use in therapy, such as antiproliferative, anticancer, and immunosuppressive therapy.

The invention discloses an application of a human polypeptide in preparation of an immune regulator. The invention is characterized in that a human polypeptide of which the amino acid sequence is KCNTATCATQRLANFLVHSSNNFGAILSSTNVGSNTY is prepared into an immune regulator for inducing CD4+CD25+Foxp3+regulatory T cells. The polypeptide preprocesses human peripheral blood mononuclear cells (PBMC) in vitro, thereby obviously increasing the quantity of human CD4+CD25+Foxp3+regulatory T cells; and the polypeptide immunizes non-obese diabetic (NOD) mice in vivo, thereby effectively preventing and treating autoimmune diabetes, improving immune pathological reaction and preventing and treating autoimmune diseases. The human polypeptide has wide application prospects in the aspects of autoimmune diseases, tissue and organ transplantation, inflammatory pathology and the like.
