Publication number: 20210163934Abstract: The object of the present invention is to provide a nucleic acid agent that can be efficiently delivered to the nervous system, particularly the central nervous system to which the BBB mechanism prevents drug delivery, and can produce an antisense effect on a target transcriptional product at the delivered site, and a composition comprising the same. Provided is a double-stranded nucleic acid complex formed by annealing a first nucleic acid strand capable of hybridizing to part of a target transcriptional product, and has an antisense effect on the target transcriptional product, to a second nucleic acid strand comprising a base sequence complementary to the first nucleic acid strand, and is bound to tocopherol or an analog thereof, cholesterol or an analog thereof, or a substituted or unsubstituted C1-30 alkyl group, a substituted or unsubstituted C2-30 alkenyl group, or a substituted or unsubstituted C1-30 alkoxy group.Type: ApplicationFiled: March 22, 2019Publication date: June 3, 2021Applicant: NATIONAL UNIVERSITY CORPORATION TOKYO MEDICAL AND DENTAL UNIVERSITYInventors: Takanori YOKOTA, Tetsuya NAGATA, Hideki FURUKAWA, Yasuo NAKAGAWA, Takatoshi YOGO, Ryosuke TOKUNOH, Shigekazu SASAKI, Kosuke HIDAKA, Tomohiro SEKI, Kenichi MIYATA, Yusuke ADACHI, Naoto ARIMURA

Publication number: 20210033901Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.Type: ApplicationFiled: October 8, 2020Publication date: February 4, 2021Inventors: Takahiro OCHIAI, Tohru SASAKI, Tetsuya NAGATA

Publication number: 20210024929Abstract: Developed and provided is: a nucleic acid agent that is efficiently delivered to the central nervous system, to which drug delivery is inhibited by the blood brain barrier mechanism, and that provides an antisense effect to a target transcription product at the delivery site; and a composition containing such a nucleic acid agent. Provided is a double-stranded nucleic acid complex consisting of a first nucleic acid strand and a second nucleic acid strand that are annealed to each other; wherein the first nucleic acid strand hybridizes with part of a target transcription product and has an antisense effect on the target transcription product; and wherein the second nucleic acid strand includes a base sequence complementary to the first nucleic acid strand and is conjugated to a phosphatidylethanolamine or an analog thereof.Type: ApplicationFiled: March 13, 2019Publication date: January 28, 2021Applicants: National University Corporation Tokyo Medical and Dental University, Takeda Pharmaceutical Company LimitedInventors: Takanori Yokota, Tetsuya Nagata, Hideki Furukawa, Yasuo Nakagawa, Takatoshi Yogo, Ryosuke Tokunoh, Shigekazu Sasaki, Kosuke Hidaka, Tomohiro Seki, Kenichi Miyata, Akio Uchida
