Chimerism a natural ability to tolerate kin, evolutionary traits connecting mammalian and protochordates [PDF]

open access: yesInvertebrate Survival Journal, 2009
In the middle of the 20th century, Owen (1945, 1954) and Billingham et al. (1953) immunological studies suggested that fetal exposure to foreign antigens during pregnancy induce immunologic tolerance in the fetus. Recently, Mold et al.

Identifying marine invasion threats and management priorities through introduction pathway analysis in a remote sub‐Antarctic ecosystem

open access: yesEcology and Evolution, Volume 14, Issue 4, April 2024.
South Georgia and the South Sandwich Islands (SGSSI) currently has only one documented established non‐native species. However, the combination of a rapidly changing climate and an increase in tourism activities make these previously isolated islands now at risk, and in need of evidence‐based knowledge of key locations and vectors for assessing ...

Immunotoxicity in Ascidians: Antifouling Compounds Alternative to Organotins—V. the Case of Dichlofluanid

open access: yesJournal of Marine Science and Engineering, 2020
Dichlofluanid has long been employed as a fungicide in agriculture and has been massively introduced in antifouling paints for boat hulls over the last two decades.

Variation in Whole‐Body Regeneration Between Botrylloides Morphs and Species

open access: yesJournal of Marine Sciences, Volume 2024, Issue 1, 2024.
Marine invertebrates exhibit an impressive regenerative capacity. Among these lineages, colonial ascidians possess the unique ability of whole‐body regeneration (WBR), in which a new adult (zooid) body is restored. Botrylloides species exemplify this regenerative capacity by regenerating new adults solely from vascular tissue within approximately 2 ...

Allogeneic Responses between Three Remote Populations of the Cosmopolitan Ascidian Botryllus schlosseri(Immunology) [PDF]

open access: yes, 1992
Colony allorecognition assays (CAAs) were performed between colonies of the world-wide distributed tunicate Botryllus schlosseri, sampled from the Mediterranean coast of Israel (Is), from Monterey, California (Mon) and from Mutsu Bay, Japan (Ja).

Evidence that ABC transporter-mediated autocrine export of an eicosanoid signaling molecule enhances germ cell chemotaxis in the colonial tunicate Botryllus schlosseri

open access: yesDevelopment, 2020
The colonial ascidian Botryllus schlosseri regenerates the germline during repeated cycles of asexual reproduction. Germline stem cells (GSCs) circulate in the blood and migrate to new germline niches as they develop and this homing process is directed ...

REGENERATION OF BUDS IN BOTRYLLUS

open access: yesThe Biological Bulletin, 1958
1. The degeneration of the adult zooid of Botryllus schlosseri, which normally occurs when the buds become functional, occurred even after all buds were removed.2. All stages of the growing buds of Botryllus have considerable regenerative ability.3. Buds damaged in the hemisphere stage became adult zooids with the same length as undamaged zooids of the

Tunic Cell Morphology and Classification in Botryllid Ascidians(Morphology) [PDF]

open access: yes, 1991
The morphology of tunic cells was investigated in ten botryllid ascidians, six Botryllus and four Botrylloides species, by means of light and electron microscopy. Three types of tunic cells were described, I.e.

Antimicrobial and Cytotoxic Properties of the Ascidians Lissoclinum patella, Oxycoryna fascicularis, Didemnum molle and Botryllus schlosseri

open access: yesPharmaceutical Sciences and Research, 2018
The aim of this research is to investigate antimicrobial and cytotoxic activity from Indonesian ascidians. Extracts prepared from the Indonesian ascidians Lissoclinum patella, Oxycoryna fascicularis, Didemnum molle and Botryllus schlosseri were assessed ...
