Publication number: 20110045091Abstract: Recent studies have demonstrated that lymphocyte-derived microparticles (LMPs) impair endothelial cell function. The present invention concerns the use of LMPs in the regulation of angiogenesis or diseases such as cancer or retinopathy of prematurity (ROP). Having long been considered as cellular debris, microparticles constitute reliable markers of vascular damage. Released into biological fluids, microparticles are involved in the modulation of key functions including immunity, inflammation, vascular remodeling and angiogenesis. The present data demonstrates that LMPs have considerable impact on angiogenesis in vitro and in vivo. In view of this, LMPs may be important contributors to the pathogenesis of diseases that are accompanied by impaired angiogenesis and could thus influence vascular function (microvascular angiogenesis and vasopermeability of ischemic tissue, alerting the body for special attention and the need for emergency repair procedures.Type: ApplicationFiled: April 9, 2009Publication date: February 24, 2011Inventors: Pierre Hardy, Chun Yang

Publication number: 20020187135Abstract: Methods for inducing antigen-specific T cell tolerance are disclosed. The methods involve contacting a T cell with: 1) a cell which presents antigen to the T cell, wherein a ligand on the cell interacts with a receptor on the surface of the T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor on the surface of the T cell which inhibits interaction of the ligand on the antigen presenting cell with the receptor on the T cell. In a preferred embodiment, the cell which presents antigen to the T cell is a B cell and the receptor on the surface of the T cell which mediates contact-dependent helper effector function is gp39. Preferably, the antagonist is an anti-gp39 antibody or a soluble gp39 ligand (e.g., soluble CD40). The methods of the invention can be used to induce T cell tolerance to a soluble antigen or to an allogeneic cell.Type: ApplicationFiled: October 1, 1998Publication date: December 12, 2002Inventors: RANDOLPH J.

Patent number: 6352694Abstract: Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR)/CD3 complex or the CD2 surface protein. To induce proliferation of an activated population T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.Type: GrantFiled: March 10, 1995Date of Patent: March 5, 2002Assignees: Genetics Institute, Inc., The Regents of the University of MichiganInventors: Carl H.

Patent number: 6270756Abstract: The invention is based on the discovery that substances which release ZAG proteins from lymphocytes also cause accelerated weight loss in humans. By administering an amount of the substance which is effective to cause the weight loss but is beneath an amount which causes side effects, a very desirable “dieter's aid” is provided. A dilute mixture of alfa interferon and gamma interferon in an aqueous medium is highly suitable for this purpose. It is administered at a much lower dosage than is generally employed for antibiotic purposes, thereby avoiding generally universal side effects. For periods of time extending at least for a few days, the weight loss composition of the invention causes weight loss at a greater weight than would be expected from fasting, at least for seriously overweight individuals.Type: GrantFiled: August 30, 1999Date of Patent: August 7, 2001Assignee: RX/IBR CorporationInventor: Arthur Dale Ericsson

Patent number: 6221352Abstract: The present invention provides vaccines and a means of vaccinating a vertebrate so as to prevent or control specific T cell mediated pathologies, including autoimmune diseases and the unregulated replication of T cells. The vaccine is composed of a T cell receptor (TCR) or a fragment thereof corresponding to a TCR present on the surface of T cells mediating the pathology. The vaccine fragment can be a peptide corresponding to sequences of TCRs characteristic of the T cells mediating said pathology. Such a peptide can bind to conventional antigens completed to MHC antigen presenting cells or to superantigens. Means of determining appropriate amino acid sequences for such vaccines are also provided. The vaccine is administered to the vertebrate in a manner that induces an immune response directed against the TCR of T cells mediating the pathology. This immune response down regulates or deletes the pathogenic T cells, thus ablating the disease pathogenesis.Type: GrantFiled: June 6, 1995Date of Patent: April 24, 2001Assignee: The Immune Response CorporationInventors: Mark D. Howell, Steven W. Brostoff, Dennis J. Carlo
