| 20100279401 | T Cell Hybridomas And Related Compositions And Methods For Assaying And Modulating T Cell Receptor-Mediated Immune Responses - The present invention provides T cell hybridomas and related compositions and assay systems for investigative, diagnostic, and therapeutic use in modulating T cell receptor (TCR)-mediated immune response. The T cell hybridomas of the invention are typically constructed by fusing a naïve or early central memory T cell isolated from a mammalian subject with an immortalizing fusion partner (e.g. mammalian lymphoid tumor cell) to yield clonal T cell hybrids.

These hybridomas are useful for screening, identifying, and characterizing T cell immune modulatory agents, for example recombinant T cell receptor ligands (RTLs) and other agents that can modulate TCR-mediated T cell immune responses. Ag-specific proliferative response profiles exhibited by the T cell hybridomas of the invention show sufficient amplitude, sensitivity and fidelity to distinguish and/or quantify the presence and/or activity of a test RTL or other test modulatory agent in screening and sensitivity assays employing the hybridomas. These and other aspects of the invention yield powerful tools and methods for developing and characterizing novel RTLs and other immune modulatory agents for use in treating immune disorders, including a wide range of autoimmune diseases, in mammals. | 11-04-2010 |

| 20110275496 | Exerciser - An exerciser includes a board, a frame, a swing rod, an upper foot rest, a lower foot rest and a resilient rope. An upper end of the swing rod is articulated to an upper end of the vertical support and a lower end of the swing rod is fixed to a central portion of the lower foot rest. The resilient rope is connected between the swing rod and the vertical support. The board is fixed on the lengthwise beam of the frame. The lengthwise beam and the vertical support of the present invention form a triangular support. The board installed on the lengthwise beam is arranged obliquely. When the pin is inserted in the pin holes of the upper portion of the vertical support and the upper end of the swing rod, the swing rod won't swing relative to the vertical support of the frame for doing sit-ups. When the pin is pulled out from the pin holes of the upper portion of the vertical support and the upper end of the swing rod, the swing rod will swing relative to the vertical support of the frame. The resilient rope provides a damping force for doing exercise to get stronger leg muscles. The present invention has a simple structure and multiple functions. | 11-10-2011 |
