  • Patent number: 11667890
    Abstract: In some embodiments, compositions and methods relating to isolated artificial antigen presenting cells (aAPCs) are disclosed, including aAPCs comprising a myeloid cell transduced with one or more viral vectors, such as a MOLM-14 or a EM-3 myeloid cell, wherein the myeloid cell endogenously expresses HLA-AB/C, ICOS-L, and CD58, and wherein the one or more viral vectors comprise a nucleic acid encoding CD86 and a nucleic acid encoding 4-1BBL and/or OX40L and transduce the myeloid cell to express CD86 and 4-1BBL and/or OX40L proteins. In some embodiments, methods of expanding tumor infiltrating lymphocytes (TILs) with aAPCs and methods of treating cancers using TILs after expansion with aAPCs are also disclosed.

  • Patent number: 11648278
    Abstract: The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. Such TILs find use in therapeutic treatment regimens.

  • Publication number: 20230117388
    Abstract: This document provides methods and materials for expanding tumor infiltrating ?? T cells (e.g., tumor infiltrating ?? T cells) in culture. For example, methods and materials for expanding large numbers of tumor infiltrating ?? T cells (e.g., tumor infiltrating ?? T cells that are predominantly V?1+) from tissue obtained from a mammal having cancer (e.g., a tumor sample), an autoimmune condition, or an infection are provided. Populations of such tumor infiltrating ?? T cells and methods and materials for using such tumor infiltrating ?? T cells and/or such populations to treat cancer within a mammal (e.g., a human) also are provided.
