Abstract: An immunotherapeutic composition is contemplated that comprises subject-derived peripheral blood mononuclear cells (PBMC) and at least one recombinant adenovirus subtype 5 (Ad5) comprising a deletion in an E1 gene region, a deletion in an E2b gene region, and a nucleic acid sequence encoding a peptide antigen, wherein the PBMC are exposed ex-vivo to the at least one Ad5 vector. Advantageously, the same PBMC composition may also be used to prepare modified NK cells, and especially modified NK include CIML NK cells, CENK cells and mCENK cells.

Abstract: Two-component vaccine formulations and methods are contemplated where the vaccine has an adjuvant component and a therapeutic component. The therapeutic component comprises preferably a recombinant therapeutic virus encoding a therapeutic antigen while the adjuvant component comprises a non-host cell or immune stimulating portion thereof. Notably, use of the adjuvant component will result in significant uptake of the therapeutic component into immune competent cells, even in the absence of receptors for entry of the therapeutic component. In addition, such adjuvant also stimulates expression of the therapeutic antigen.

Abstract: Compositions, methods, and uses of recombinant IL-8 antibody, fragment thereof or single chain variable fragment (scFv) having high affinity to IL-8 to target tumor-expressed or endogenous IL-8 are presented. Preferably, the recombinant IL-8 antibody or scFv fragment includes a VH segment comprising a first amino acid sequence selected from SEQ ID NO. 1-15, 31-32, and/or a VL segment comprising a second amino acid sequence selected from SEQ ID NO. 16-30, 33-34. The recombinant IL-8 antibody or scFv fragment can be formulated as pharmaceutical compositions to administer to a patient having a tumor to reduce metastasis of the tumor, reduce immune suppression in the tumor microenvironment or reduce Th2 mediated immune response.

Abstract: Compositions, methods, and uses of recombinant B7-H4 protein or binding motifs to B7-H4 protein that can reduce the immune suppression effect of B7-H4 in relation to T cell activation, proliferation, and conversion. Preferably, the recombinant B7-H4 protein has a plurality of mutations in N-glycosylation residue to reduce its inhibitory effect to T cell activation and proliferation. The recombinant protein having binding motifs to B7-H4 protein preferably includes a binding motif to IgC domain and another binding motif to IgV domain such that the immune-suppressive effects by two Ig-like domains are concurrently reduced.

Abstract: A method for the production of proteins used in the in vitro transcription (IVT) of messenger RNA (mRNA), wherein the proteins are evaluated for purity and efficacy by the efficiency with which mRNA synthetically derived therefrom, subsequently transfects cells and produces encoded proteins.

Abstract: Methods for detecting the presence of sever acute respiratory coronavirus 2 (SARS-CoV-2) are provided. The methods comprise incubating a sample comprising T-cells from an individual with one or more SARS-CoV-2 antigens, each antigen having a T-cell epitope, and detecting a change in state of T-cells in the sample. The change in state may be detected by determining the presence or level of a secreted, immune response indicator, such as interferon-gamma (IFN-?).

Abstract: The invention relates to a composition comprising a peptide and an immunotherapeutic composition, and a method of inducing phagocytosis without inflammation comprising administering the composition.

Abstract: A pharmaceutical compositions and methods for immunotherapy are provided. The pharmaceutical composition includes a genetically-engineered bacterium expressing a human disease-related antigen(s), preferably two or more patient-specific tumor antigens as a polytope. The bacterium has genetically engineered lipopolysaccharide or a patient's own endosymbiotic bacterium so that the bacterium expresses endotoxin at a low level, which is insufficient to induce a CD-14 mediated sepsis. The genetically-engineered bacterium can be administered to the patient, either systemically or locally, to induce tumor-specific immune response.
