    摘要: 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.

    摘要: The present invention relates to genetically modified B cells and their uses thereof, for example, for the treatment of a variety of diseases and disorders, including cancer, heart disease, inflammatory disease, muscle wasting disease, neurological disease, and the like. In certain embodiments, the invention relates to an isolated modified B cell (“CAR-B cell), capable of expressing a chimeric receptor (“CAR-B receptor”), wherein said chimeric receptor comprises (a) an extracellular domain; (b) a transmembrane domain; and (c) a cytoplasmic domain that comprises at least one signaling domain. In various embodiments, the invention comprises an isolated modified B cell, wherein said B cell is capable of expressing and secreting a payload, wherein the payload is not naturally expressed in a B cell or is expressed at higher levels than is naturally expressed in a B cell. In various embodiments, the payload is an antibody or fragment thereof.
