Publication number: 20220356462Abstract: A nucleic acid amplification method using a solid-phase carrier according to the present invention comprises: capturing a target nucleic acid comprising mRNA on a solid-phase carrier; carrying out complementary-strand synthesis on the solid phase; carrying out exonuclease treatment to degrade and remove unreacted target- capturing nucleic acid on the solid phase; and then carrying out mRNA degradation and homopolymer addition by TdT reaction in the presence of a chain-terminating nucleotide triphosphate. According to the method of the present invention, cDNA can be stably and highly efficiently amplified even from a small amount of sample even in cases where the ratio of the amount of enzyme to the DNA substrate on the solid phase is excessive, where the reaction time is excessive, and/or where reagents show lot-to-lot variation.Type: ApplicationFiled: July 10, 2020Publication date: November 10, 2022Applicant: TOKYO UNIVERSITY OF SCIENCE FOUNDATIONInventors: Kouji MATSUSHIMA, Satoshi UEHA, Shigeyuki SHICHINO, Satoru ITO, Hiroyasu AOKI

Patent number: 10746726Abstract: Means that enables monitoring of an anticancer effect of an anti-CD4 antibody or an anticancer drug targeting an immune checkpoint is disclosed. The method for testing a therapeutic effect of a cancer therapy of the present invention is a method for testing a therapeutic effect of an anticancer drug comprising as an effective ingredient an anti-CD4 antibody or an anticancer drug targeting an immune checkpoint, which method comprises investigation of expression of (1) at least one immune checkpoint receptor, (2) CD8, and (3) at least one cell surface molecule selected from the group consisting of CD44 and CD45RO, on T cells using a sample derived from a patient who received the anticancer drug. Induction of a T cell population which is positive for the immune checkpoint molecule (1) and positive for CD8, and which shows high expression of CD44 and/or high expression of CD45RO, indicates that said anticancer drug is producing a therapeutic effect in said patient.Type: GrantFiled: December 2, 2015Date of Patent: August 18, 2020Assignees: THE UNIVERSITY OF TOKYO, IDAC THERANOSTICS, INC.Inventors: Kouji Matsushima, Satoshi Ueha, Satoru Ito, Shoji Yokochi, Yoshiro Ishiwata

Patent number: 9156912Abstract: The object of the invention is to provide an immunological reconstitution promoter or a prophylactic agent for infections for use in allogeneic hematopoietic stem cell transplantation therapy for tumors. The promoter or prophylactic agent enables the amelioration of delayed immune reconstitution or the prevention of infection following transplantation, while maintaining the GVT effect of allogeneic hematopoietic stem cell transplantation. Specifically, in a transplant patient in whom immune reconstitution is delayed, such reconstitution can be promoted by administering, at an early stage following transplantation, a substance capable of depleting CD4+ cells. Early completion of infection management in the patient and improvement in the survival rate are anticipated as a result. In addition, the risk of complications associated with allogeneic hematopoietic stem cell transplantation is reduced, enabling more widespread use of this therapy.Type: GrantFiled: November 4, 2009Date of Patent: October 13, 2015Assignee: The University of TokyoInventors: Kouji Matsushima, Satoshi Ueha, Yusuke Shono
