Publication number: 20150298632Abstract: A vehicle exterior member attaching structure for attaching a vehicle exterior member onto a protruding target location of a vehicle includes a vehicle engagement portion, an attachment hole, a covering portion, an engagement portion, and an attachment piece. When inserted into the attachment hole, the attachment piece positions the covering portion at a temporary position with respect to the target section. When the covering portion is pulled toward the vehicle engagement portion and the attachment piece is pressed against the rim of the attachment hole, the attachment piece is rotated in a direction opposite to the direction in which the covering portion is pulled. In a state in which the covering portion is positioned at a desired position, the attachment piece returns to an original position to maintain engagement between the vehicle engagement portion and the engagement portion.Type: ApplicationFiled: November 25, 2013Publication date: October 22, 2015Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Kenji CHIBA, Muneaki INAGAKI

Publication number: 20050090558Abstract: The methods and compositions of the invention and the compounds used in the invention involve a novel immunosuppression mechanism, accelerated lymphocyte homing immunosuppression (ALH-immunosuppression). For example, the compound FTY720 specifically directs lymphocytes to the peripheral lymph nodes, mesenteric lymph nodes, and Peyer's patches. By reversibly sequestering lymphocytes in these tissues, the compounds can inhibit an immune response in a mammal. Understanding these mechanisms provides a novel immunosuppression therapy that can synergistically interact with other immunosuppressive compounds. Screening methods for identifying similar ALH-immunosuppression compounds are also described. The invention allows better treatments and therapies wherever an immunosuppression regimen is desired.Type: ApplicationFiled: June 27, 2003Publication date: April 28, 2005Inventors: Kenji Chiba, Kunitomo Adachi
