Abstract: In certain embodiments, described herein is a method of treating a subject infected with a pathogen encoding an Fc-binding protein comprising administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising an Fc region of an immunoglobulin G antibody. Also described herein is a method for treating cancer in a subject undergoing oncolytic viral therapy comprising administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising an Fc region of an immunoglobulin G antibody. Further described herein is a method of activating natural killer (NK) cells in a subject infected with a pathogen, comprising administering to the subject a pharmaceutical composition comprising an Fc region of an immunoglobulin G antibody.

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: Provided herein are methods of treating cancer in a subject including detecting an amount of PD-L1(+) natural killer (NK) cells in a biological sample from the subject and treating the subject with an anti cancer therapy. Provided herein are methods of treating cancer in a patient including isolating natural killer (NK) cells from a subject, producing a population of PD-L1(+) NK cell from the isolated NK cells, and administering the population of PD-L1(+) NK cells into the patient.

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.
