The present invention is based on the seminal discovery that targeted immunomodulatory antibodies and fusion proteins can counter act or reverse immune tolerance of cancer cells. Cancer cells are able to escape elimination by chemotherapeutic agents or tumor-targeted antibodies via specific immunosuppressive mechanisms in the tumor microenvironment and such ability of cancer cells is recognized as immune tolerance. Such immune suppressive mechanisms include immunosuppressive cytokines (for example, Transforming growth factor beta (TGF-β) and regulatory T cells and / or immunosuppressive myeloid dendritic cells (DCs). By counteracting tumor-induced immune tolerance, the present invention provides effective compositions and methods for cancer treatment, optional in combination with another existing cancer treatment. The present invention provides strategies to counteract tumor-induced immune tolerance and enhance the antitumor efficacy of chemotherapy by activating and leveraging T cell-mediated adaptive antitumor immunity against resistant or disseminated cancer cells.

Methods and devices are described for the regulation of Transforming Growth actor (TGF)-β1, β2, and / or β3 protein gene expression in bone cells and other tissues via the capacitive coupling or inductive coupling of specific and selective electric fields to the bone cells or other tissues, where the specific and selective electric fields are generated by application of specific and selective electric and electromagnetic signals to electrodes or one or more coils or other field generating device disposed with respect to the bone cells or other tissues so as to facilitate the treatment of diseased or injured bone and other tissues. By gene expression is meant the up-regulation or down-regulation of the process whereby specific portions (genes) of the human genome (DNA) are transcribed into mRNA and subsequently translated into protein. Methods and devices are provided for the targeted treatment of injured or diseased bone and other tissue that include generating specific and selective electric and electromagnetic signals that generate fields in the target tissue optimized for increase of TGF-β1, β2, and / or β3 protein gene expression and exposing bone and other tissue to the fields generated by specific and selective signals so as to regulate TGF-β1, β2, and / or β3 protein gene expression in such tissue. The resulting methods and devices are useful for the targeted treatment of bone fractures, fractures at risk, delayed unions, nonunion of fractures, bone defects, spine fusions, osteonecrosis or avascular necrosis, as an adjunct to other therapies in the treatment of one or all of the above, in the treatment of osteoporosis, and in other conditions in which TGF-β1, β2, and / or β3 protein may be implicated.

Specific binding members, particularly antibodies and fragments thereof, which bind to transforming growth factor beta 1 (TGF-β1) are provided, particularly recognizing human and mouse TGF-β1 and not recognizing or binding TGF-β2 or TGF-β3. Particular antibodies are provided which specifically recognize and neutralize TGF-β1. These antibodies are useful in the diagnosis and treatment of conditions associated with activated or elevated TGF-β1, including cancer, and for modulating immune cells and immune response, including immune response to cancer or cancer antigens. The anti-TGF-β1 antibodies, variable regions or CDR domain sequences thereof, and fragments thereof may also be used in therapy in combination with chemotherapeutics, immune modulators, or anti-cancer agents and / or with other antibodies or fragments thereof. Antibodies of this type are exemplified by the novel antibodies hereof, including antibody 13A1, whose sequences are provided herein.
