Blockade of immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-1 (PD-1) shows promise in patients with cancer. Inhibitory antibodies directed at these receptors have been shown to break immune tolerance and promote anti-tumor immunity. These agents work particularly well in patients with a certain category of tumor. Such tumors may be particularly susceptible to treatment because of the multitude of neoantigens which they produce.

The present invention provides compositions and methods for treating cancer in a human. The invention relates to targeting the stromal cell population in a tumor microenvironment. For example, in one embodiment, the invention provides a composition that is targeted to fibroblast activation protein (FAP). The invention includes a chimeric antigen receptor (CAR) which comprises an anti-FAP domain, a transmembrane domain, and a CD3zeta signaling domain.

Blood-brain barrier permeable peptide compositions that contain variable antigen binding domains from camelid and/or shark heavy-chain only single-domain antibodies are described. The variable antigen binding domains of the peptide compositions bind to therapeutic and diagnostic biomarkers in the central nervous system, such as the amyloid-beta peptide biomarker for Alzheimer's disease. The peptide compositions contain constant domains from human IgG, camelid IgG, and/or shark IgNAR. The peptide compositions include heavy-chain only single-domain antibodies and compositions with one or more variable antigen binding domain bound to one or more constant domains.

Bifunctional fusion proteins having Tumstatin active fragments and CD137L extracellular regions are provided. The proteins exhibit activities to inhibit the proliferation of human umbilical vein endothelial cells and to costimulate the proliferation of T cells. They can be used for the treatment of various tumor-related diseases and the regulation of angiogenesis and immunological effects in humans.

The present invention relates to a novel antibody against HERV-K envelope that targets a conserved region not affected by glycosylation or by native conformation, and its use in diagnostics and/or is therapy.
