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.

Passive antibody dependent cell-mediated activation

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.

EGFR-directed car therapy for glioblastoma

A polypeptide is disclosed that binds tumor-associated antigens (TAA) on the surface of cancer cells and a NKG2D receptor. The NKG2D receptor is expressed on the surfaces of killer cells such as natural killer cells, T cells, natural killer T cells, and gamma delta T cells. In some cases, the TAA is CS-1 or EGFRvIII. Also disclosed are polynucleotides encoding the disclosed polypeptides, vectors comprising the disclosed polynucleotides, and host cells comprising the disclosed vectors. Also disclosed are bivalent antibodies comprising the disclosed polypeptides. Also disclosed are pharmaceutical compositions comprising the disclosed antibodies. Also disclosed are methods of treating cancer in a subject using the disclosed bi-specific antibodies.

Bivalent antibody directed against NKG2D and tumor associated antigens

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.

FLT3 directed car cells for immunotherapy

Provided herein are boronic acid esters of boronic acid therapeutic agents, such as bortezomib. The boronic acid esters can be used to prepare liposomal formulations of boronic acid therapeutic agents with improved properties, such as enhanced stability. This disclosure, in one aspect, relates to compositions and methods of making and using the compositions.

Boronic acid esters and pharmaceutical formulations thereof

Methods and compositions involving miR-122, miR-15, miR-21, and miR-155, which are useful for the treatment of various diseases, such as cancers, are described. Further described are methods and compositions useful for increasing, activating, or regulating NK cells and surface antigens.

Activation of innate immunity by miRNA for cancer and infection treatment

Methods for stably transfecting mammalian natural killer cells comprising: transfecting a packaging cell line with a retroviral expression vector; culturing the transfected packaging cell line in a cell culture medium; and culturing the mammalian natural killer cells with the cell culture medium. Natural killer cells transfected according to the disclosed methods are also provided.

Methods for transfecting natural killer cells

The present invention provides isolated cells that are selectively enriched for hematopoietic progenitor cells that are precursors for natural killer (NK) cells. These cells are both CD34 and CD45RA positive and express C-integrin &#x3b2;, and are referred to as CD34CD45RAC-integrin &#x3b2;. The invention provides methods for isolating these cells, for inducing formation of CD56NK cells, and for treating diseases associated with immunodeficiency and cancer.

CD34(+) cells and their methods of use

Methods for treating a subject with a cancer that is characterized by overexpression of HER2 receptor protein using a combination of interleukin-2 (IL-2) or variant thereof and at least one anti-HER2 antibody or fragment thereof are provided. These anti-tumor agents are administered as two separate pharmaceutical compositions, one containing IL-2 (or variant thereof), the other containing at least one anti-HER2 antibody (or fragment thereof), according to a dosing regimen. Administering of these two agents together potentiates the effectiveness of the anti-HER2 antibody alone, resulting in a positive therapeutic response that is improved with respect to that observed with this anti-tumor agent.

Methods of therapy for cancers characterized by overexpression of the HER2 receptor protein

A method for treating a primary central nervous system lymphoma in an individual relates to administering intrathecally or intralesionally a therapeutically effective amount of a Fas-cross-linking composition thereby inducing the lymphoma cells to undergo Fas-mediated cytotoxicity. The Fas-cross-linking composition may be an agonist anti-human Fas monoclonal antibody or fragments thereof, soluble Fas-ligand (Fas-L), and a combination thereof. In another embodiment, the lymphoma is pretreated with a composition that enhances Fas-mediated cytotoxicity induced by a Fas-cross-linking composition, followed by treatment with the Fas-cross-linking composition.
