The invention disclosed herein relates to improved methods for expanding cell populations, particularly B cell populations. The invention further relates to improved B-cell expansion media, compositions comprising expanded B cells and methods of using such expanded B cells. The invention further relates to methods of treating diseases or disorders wherein a population of B cells is obtained and cultured, and wherein said B cells are engineered to express a payload and/or a chimeric receptor, and wherein said B cells are administered to a subject.

Provided herein are recombinant poxviruses that are stable through successive passaging of the recombinant poxviruses. More particularly, the recombinant poxviruses comprise one or more modified nucleic acids encoding MUC1, CEA, and/or TRICOM antigens, wherein the recombinant poxviruses are stable through successive passaging. Also, provided herein are compositions and method related thereto.

Disclosed herein are a pharmaceutical composition and a disease therapy method. The pharmaceutical composition relates to an artificial chimeric antigen receptor (CAR). Specifically, the pharmaceutical composition includes a CAR protein that is highly specific to CD19 antigen, a vector that is capable of inducing a cell to generate the certain CAR 19 protein and a population of a modified mammal cell including the CAR19 protein, the vector or combination thereof. Furthermore, the artificial CAR19 includes a CD19 antigen-binding fragment, a transmembrane domain, and a signaling domain. The CD19 antigen-binding fragment is a single-chain variable fragment (scFv) having specific amino acid sequences. Additionally, the method relates to a cancer therapy by using said modified mammal cells. Furthermore, the method includes the steps of purifying a population of autologous cells, modifying the population of autologous cells with an artificial CAR, and administrating the modified autologous cells.

Disclosed herein are novel compositions and methods for stimulation of and the production or expansion of natural killer (NK) cells.

The disclosure provides liposomes (e.g., cancer-targeting liposomes) with ligands (e.g., EGFR ligands and ICAM-1 ligands) conjugated to liposome surfaces. In some embodiments, the molecular ratio of different ligands complement the relative molecular density (i.e., ratio) of overexpressed protein on the surface of a cell targeted by the liposome (e.g., cancer cell).

The present invention demonstrated that soluble fibrin binds to both Mac-1 and ICAM-1-expressing cells and inhibited adherence of these cells and immune cytotoxicity, thus inducing immune suppression in cancer. Additionally, the present invention also demonstrated that soluble fibrin enhanced metastasis in an in vivo model. Furthermore, the present invention demonstrated the utility of specific peptides that block binding of soluble fibrin to these cells as therapeutic agents in cancer progression and metastasis. It is further contemplated that these peptides can also be used to treat other diseases such as cardiovascular disease, arthritis and in many inflammatory responses where there is increased levels of soluble fibrin.

Chimeric antigen receptors containing ROR1 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.
