Abstract: The present invention is a method for inhibiting Treg cell functional activities by blocking Treg cell-mediated mast cell activation. It has been found IL-9 produced by Treg cells activates mast cells, which in turn mediate an amplification loop critical for graft tolerance and immune responses to tumors. Thus, a method for enhancing an immune response to a vaccine, such as a cancer vaccine, is also provided as is a method for increasing cell and humoral immunity in a subject.

Abstract: The present invention relates to a fusion proteins comprising regulatory T cell protein, VISTA (V-domain Immunoglobulin Suppressor of T cell Activation (PD-L3) and an immunoglobulin protein (Ig). The invention also provides the use of VISTA polypeptides, multimeric VISTA polypeptides, VISTA-conjugates (e.g., VISTA-Ig), and VISTA antagonists for the treatment of autoimmune disease, allergy, and inflammatory conditions.

Abstract: The present invention relates to novel regulatory T cell proteins. One protein, designated PD-L3, resembles members of the PD-L1 family, and co-stimulates ?CD3 proliferation of T cells in vitro. A second, TNF-like, protein has also been identified as being upregulated upon ?CD3/?GITR stimulation. This protein has been designated Treg-sTNF. Proteins, antibodies, activated T cells and methods for using the same are disclosed. In particular methods of using these proteins and compounds, preferably antibodies, which bind or modulate (agonize or antagonize) the activity of these proteins, as immune modulators and for the treatment of cancer, autoimmune disease, allergy, infection and inflammatory conditions, e.g.

Abstract: Improved (safer and more effective) methods of therapy using TNF-R agonists, e.g., CD40 agonists are provided. These methods provide for the addition of an amount of a type 1 interferon and/or a TLR agonist that is effective to prevent or reduce the toxicity (liver toxicity) that may otherwise result in some patients of the TNF-R agonist is used as a monotherapy (without the type 1 interferon and/or TLR agonist).

Abstract: Improved anti-CD154 antibodies are provided herein which have ablated FcR binding and/or complement binding/activation. The use of these antibodies for inducing tolerance and treating immune diseases including autoimmunity, inflammation and allergic disorders is disclosed herein.

Abstract: The present invention relates to a novel regulatory T cell protein. This protein, designated PD-L3 OR VISTA resembles members of the PD-L1 family, identified a novel and structurally-distinct, Ig-superfamily inhibitory ligand, whose extracellular domain bears homology to the B7 family ligand PD-L1. This molecule is designated as PD-L3 OR VISTA or V-domain Immunoglobulin Suppressor of T cell Activation (VISTA). Expression of VISTA is primarily within the hematopoietic compartment and is highly regulated on myeloid APCs and T cells. Therapeutic intervention of the VISTA inhibitory pathway represents a novel approach to modulate T cell-mediated immunity for the treatment of a wide variety of cancers, e.g., ovarian, bladder cancer and melanomas. Also, VISTA proteins, especially multimeric VISTA proteins and antibodies may be used to suppress T cell immunity in autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis and arthritic conditions such as RA.

Abstract: The present invention relates to a method for producing adaptive regulatory T cells from effector T cells by contacting the effector T cells with retinoic acid. Adaptive regulatory T cells produced by this method are Foxp3+, home to the gut, and are refractory to reversion in vivo. As such, such cells find application in the treatment of autoimmune disease and facilitating transplantation tolerance.

Abstract: The present invention provides immunostimulatory combinations. Generally, the immunostimulatory combinations include a TLR agonist and a TNF/R agonist. Certain immunostimulatory combinations also may include an antigen.
