A Novel Hemocyte-Derived Peptide and Its Possible Roles in Immune Response of Ciona intestinalis Type A.

Shin Matsubara Rin Iguchi Michio Ogasawara Hiroya Nakamura Tatsuki R Kataoka Akira Shiraishi Tomohiro Osugi Tsuyoshi Kawada Honoo Satake

International journal of molecular sciences 25(4) 2024年2月

A wide variety of bioactive peptides have been identified in the central nervous system and several peripheral tissues in the ascidian Ciona intestinalis type A (Ciona robusta). However, hemocyte endocrine peptides have yet to be explored. Here, w...

scRNA-seq analysis of cells comprising the amphioxus notochord.

Hiroki Takahashi Kanako Hisata Rin Iguchi Sakura Kikuchi Michio Ogasawara Noriyuki Satoh

Developmental biology 2024年1月

Cephalochordates occupy a key phylogenetic position for deciphering the origin and evolution of chordates, since they diverged earlier than urochordates and vertebrates. The notochord is the most prominent feature of chordates. The amphioxus notoc...

CatSper mediates not only chemotactic behavior but also the motility of ascidian sperm

Taiga Kijima Daisuke Kurokawa Yasunori Sasakura Michio Ogasawara Satoe Aratake Kaoru Yoshida Manabu Yoshida

Frontiers in Cell and Developmental Biology 11 2023年11月

Introduction: Sperm motility, including chemotactic behavior, is regulated by changes in the intracellular Ca²⁺ concentration, and the sperm-specific Ca²⁺ channel CatSper has been shown to play an important role in the regula...

Multi-regional expression of pancreas-related digestive enzyme genes in the intestinal chamber of the ascidian Ciona intestinalis type A.

Rin Iguchi Kanae Usui Satoshi Nakayama Yasunori Sasakura Toshio Sekiguchi Michio Ogasawara

Cell and tissue research 2023年10月

Bilateria share sequential steps in their digestive systems, and digestion occurs in a pre-absorption step within a chamber-like structure. Previous studies on the ascidian Ciona intestinalis type A, an evolutionary research model of vertebrate or...

Repetitive and zonal expression profiles of absorption-related genes in the gastrointestinal tract of ascidian Ciona intestinalis type A.

Rin Iguchi Satoshi Nakayama Yasunori Sasakura Toshio Sekiguchi Michio Ogasawara

Cell and tissue research 2023年9月

Intestinal absorption is essential for heterotrophic bilaterians with a tubular gut. Although the fundamental features of the digestive system were shared among chordates with evolution, the gut morphologies of vertebrates diverged and adapted to ...
