Disclosed are compositions related to synthetic PD-L1 peptides, chimeric PD-L1 peptides, anti-PD-L1 antibodies and N methods of treating cancers, autoimmune diseases, and Alzheimer's disease using said peptides or antibodies.

The invention relates to a virus-like particle (VLP) based vaccine. The virus-like particle constitutes a non-naturally occurring, ordered and repetitive antigen array display scaffold which can obtain a strong and long-lasting immune response in a subject. The VLP-based vaccine may be used for the prophylaxis and/or treatment of a disease including, but is not limited to, cancer, cardiovascular, infectious, chronic, neurological diseases/disorders, asthma, and/or immune-inflammatory diseases/disorders.

This document provides methods and materials relating to isolated polypeptides, polypeptide preparations, vaccine preparations (e.g., anti-cancer vaccine preparations), and methods for vaccinating mammals. For example, polypeptides (e.g., CMV, MUC1, HER2, Mesothelin (MESO), TRAG-3, or CALR polypeptides) having the ability to be processed into different polypeptides such that the processed polypeptides as a group are capable of being presented by different MHC molecules present in a particular mammalian population are provided.

The present invention provides combination therapies and methods of treating cancer, including, cancers that are resistant to PD-1 therapy. The combination therapies described herein comprise a DNA vaccine to a tumor antigen, anti-PD-1 therapy, and an anti-LAG-3 therapy, which provides an increased T cell response against the cancer.

The disclosure pertains to a recombinant adeno-associated virus (rAAV) comprising an Anc80L65 capsid for delivering a polynucleotide (e.g., a transgene) into the central nervous system (CNS). Further provided includes methods for treating CNS diseases using the rAAV and pharmaceutical compositions comprising the rAAV.

Cancer is treated using coordinated treatment regimens that uses various compounds and compositions that drive a tumor from the escape phase of cancer immunoediting to the elimination and equilibrium phase of cancer immunoediting.

This disclosure relates to methods of treating cancer using dendritic cells pulsed with tumor membrane vesicles as disclosed herein. In certain embodiments, the tumor membrane vesicles contain fusion proteins with a cytokine and a glycosyl phosphatidylinositol domain. In certain embodiments, the cytokine is granulocyte-macrophage colony-stimulating factor (GM-CSF). In certain embodiments, tumor membrane vesicles contain fusion proteins with IL-12 and a glycosyl phosphatidylinositol domain.

Fixed dose HER2 antibody formulations for subcutaneous administration are provided along with their use in the treatment of cancer. The formulations include fixed dose subcutaneous formulations of pertuzumab and subcutaneous co-formulations of pertuzumab and trastuzumab, and their use in the treatment of cancer.

The present disclosure provides compositions and methods for enhancing immunity (or immune response). The compositions and methods are particularly useful for potentiating immune response of a lymphoid cell. The compositions and methods are applicable for treating cancer and other diseases.

The present disclosure provides methods and compositions related to the modification of immune effector cells to increase therapeutic efficacy. In some embodiments, immune effector cells modified to reduce expression of one or more endogenous target genes, or to reduce one or more functions of an endogenous protein to enhance effector functions of the immune cells are provided. In some embodiments, immune effector cells further modified by introduction of transgenes conferring antigen specificity, such as exogenous T cell receptors (TCRs) or chimeric antigen receptors (CARs) are provided. Methods of treating a cell proliferative disorder, such as a cancer, using the modified immune effector cells described herein are also provided.
