Abstract: Described herein are single vectors that, when expressed in cytolytic immune cells, results in both the expression of (1) a CAR targeting tumor-associated antigens and (2) secretion of a bispecific antibody that on one end recognizes NKG2D expressed on both innate and antigen specific cytolytic immune cells and on the other end targets tumor associated antigens. Unexpectedly, these modifications to the T cells result in enhanced survival and proliferation in vivo. Thus, therapeutic and diagnostic uses are disclosed.

Abstract: Glioblastoma (GB) remains the most aggressive primary brain malignancy; brain metastasis, such as breast cancer brain metastases (BCBMs), are also aggressive and are associated with poor prognosis. Adoptive transfer of chimeric antigen receptor (CAR)-modified immune cells has emerged as a promising anti-cancer approach, yet the potential utility of CAR-engineered cells to treat brain cancers has not been explored. The present disclosure presents compostions and methods for using CAR expressing cells in the treatment of various cancers, including brain cancers such as GB and BCBMs.

Abstract: CAR cells targeting FLT3 antigens in combination with a secreted anti-PD-1 and anti-PD-L1 antibodies or anti-PD-1-anti-PD-L1 bispecific antibodies are described as a new method of cancer treatment. It is proposed that these combination therapies are safe and effective in patients and can be used to treat human tumors and cancer.

Abstract: CAR cells targeting FLT3 relevant antigens are described as a new method of cancer treatment. It is proposed that FLT3 CAR cells are safe and effective in patients and can be used to treat human tumors and cancer.
