Publication number: 20240166736Abstract: An objective of the present invention is to provide an anti-TSPAN8/anti-CD3 bispecific antibody and an anti-TSPAN8 antibody usable in treatment or prevention in human. A human monoclonal antibody producing mouse was immunized with a peritoneal disseminated cancer cell isolated from a patient, to obtain an antibody 16B11 and an antibody 16B12 that selectively bind to a peritoneal disseminated cancer cell. These antibodies were anti-TSPAN8 antibodies that bind to the region from amino acid positions 126 to 155 of TSPAN8 and exhibited strong binding activity to TSPAN8 expressed in the peritoneal disseminated cancer cell. Further, an anti-TSPAN8(16B11)-anti-CD3 bispecific antibody produced based on the sequence of 16B11 exhibited a cytotoxic activity against the TSPAN8-expressing cancer cell in vitro, exerted an anti-tumor action on TSPAN8-expressing cancer cell-bearing mice in vivo, and extended the lifetime of peritoneal dissemination model mice.Type: ApplicationFiled: December 26, 2023Publication date: May 23, 2024Applicants: Astellas Pharma Inc., National Cancer CenterInventors: Yoshiyuki TENDA, Masatoshi YURI, Daisuke YAMAJUKU, Takeshi TSUTSUMI, Yuko KUSUZAKI, Hiroki SASAKI, Fumiko CHIWAKI, Masayuki KOMATSU

Patent number: 11736830Abstract: A solid-state imaging element includes a pixel and an image processing unit. The pixel has a common transistor, a charge accumulation unit, and a power supply. The common transistor has a first terminal and a second terminal. The common transistor maintains a voltage of the first terminal at a predetermined voltage with a voltage applied from the power supply and outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the second terminal, based on a condition that an element voltage is a ground voltage. The common transistor outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the first terminal, based on the element voltage is higher than the ground voltage. The image processing unit generates a luminance image according to a change in the voltage output from the second terminal of the common transistor.Type: GrantFiled: September 28, 2022Date of Patent: August 22, 2023Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, MIRISE Technologies CorporationInventor: Hiroki Sasaki
