RESUMEN
CD47 is a transmembrane glycoprotein widely expressed on cells and an important signal molecule for immune escape of tumor cells. CD47, which is highly expressed in bladder cancer cells, can interact with signal regulatory proteins on the surface of macrophages- α (SIRPα). It combines and transmits immunosuppressive signals to protect tumor cells from phagocytosis, thereby mediating their immune escape. CD47-SIRPα signal pathways have become the focus of tumor cell immune checkpoint research at this stage. This article reviewed the research progress in the mechanism and clinical value of CD47 in bladder cancer.
RESUMEN
Triatoma rubrofasciata is a wide-spread vector of Chagas disease in Americas. In this study, we completed the mitochondrial genome sequencing of T. rubrofasciata. The total length of T. rubrofasciata mitochondrial genome was 17,150 bp with the base composition of 40.4% A, 11.6% G, 29.4% T and 18.6% C. It included 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and one control region. We constructed a phylogenetic tree on the 13 protein-coding genes of T. rubrofasciata and other 13 closely related species to show their phylogenic relationship. The determination of T. rubrofasciata mitogenome would play an important role in understanding the genetic diversity and evolution of triatomine bugs.
