  • Publication number: 20210198667
    Abstract: The purpose of the present invention is to provide a molecule having a significant effect on the development of fibrosis and a substance capable of inhibiting fibrosis. This biomarker for fibrosis comprises RNA binding motif protein 7 (RBM7) and is useful as a biomarker for diagnosis of fibrosis. This fibrosis detection method comprising the step of detecting RBM7 in a biological sample from a subject preferably using an anti-RBM7 antibody is useful for diagnosis of fibrosis. This antifibrotic agent containing a substance which inhibits the expression of RBM7, preferably at least one nucleic acid drug selected from the group consisting of siRNAs, shRNAs, dsRNAs, miRNAs, and antisense nucleic acids against RBM7, is useful for treatment of fibrosis.

  • Patent number: 10172927
    Abstract: The instant invention is to provide a method for detecting and measuring malaria infection utilizing the induction by hemozoin (HZ); a method for screening a vaccine for malaria infection and a preventative or therapeutic agent for malaria infection using the method for detecting and measuring; and a means for regulating the induction of innate immunity using the HZ, synthetic HZ, or derivatives thereof as an adjuvant or immunostimulant. Malaria infection is detected and measured of by detecting and measuring HZ-induced, TLR9-mediated, and MyD88-dependent innate immune activity. The detection and measurement of malaria infection can be used to diagnose malaria infection. The method for detecting and measuring is also used for screening a vaccine for malaria infection and a preventative or therapeutic agent for malaria infection. Further, HZ, synthetic HZ, or derivatives thereof are used as an adjuvant or immunostimulant to regulate HZ-induced innate immune induction.
