Polar Constituents of the Tunicate Botryllus schlosseri

Russian Journal of Bioorganic Chemistry, 2002
Eighteen compounds were identified by GC-MS of their trimethylsilyl derivatives in n-butanolic extract from the biomass of Botryllus schlosseri. Three of them, 5-oxoproline, 5-hydroxyhydantoin, and kinurenic acid, were found in marine invertebrates for the first time. In addition to cellulose, the biomass was also shown to contain complex water-soluble

Interpopulational allogeneic reactions in the colonial protochordate Botryllus schlosseri

International Immunology, 1991
Botryllus schlosseri is a cosmopolitan encrusting colonial tunicate which undergoes a natural transplantation reaction. When the growing edges of two colonies come into direct contact by interaction between their extracorporeal blood vessel termini, the ampullae, they either reject each other or fuse.

Phagocyte dynamics in the blastogenetic cycle of the colonial ascidian Botryllus schlosseri: cell senescence, segregation and clearance after efferocytosis.

Developmental and Comparative Immunology
In the colonial ascidian Botryllus schlosseri, phagocytes are involved in the clearance of apoptotic cells and corpses during the periodical generation changes or takeovers (TOs) that assure the renewal of the colonial zooids.

Proteomic profiling of Botryllus schlosseri, an emerging model organism

Physiology
Botryllus schlosseri is a colonial chordate species that exhibits robust stem cell-mediated regeneration capacities throughout life. It grows through a process of colonial budding known as blastogenesis, in addition to its sexual reproduction mode ...

Toward a resolution of the cosmopolitan Botryllus schlosseri species complex (Ascidiacea, Styelidae): mitogenomics and morphology of clade E (Botryllus gaiae)

, 2020
Botryllus schlosseri is a model colonial ascidian and a marine invader. It is currently recognized as a species complex comprising five genetically divergent clades, with clade A globally distributed and clade E found only in Europe.

UV-B radiation bearings on ephemeral soma in the shallow water tunicate Botryllus schlosseri.

Ecotoxicology and Environmental Safety, 2020
Sedentary shallow water marine organisms acquire numerous protective mechanisms to mitigate the detrimental effects of UV radiation (UV-R). Here we investigated morphological and gene expression outcomes in colonies of the cosmopolitan ascidian Botryllus

Sixty years of experimental studies on the blastogenesis of the colonial tunicate Botryllus schlosseri.

Developmental Biology, 2019
In the second half of the eighteenth century, Schlosser and Ellis described the colonial ascidian Botryllus schlosseri garnering the interest of scientists around the world. In the 1950's scientists began to study B.

Functional amyloidogenesis in immunocytes from the colonial ascidian Botryllus schlosseri: Evolutionary perspective

Developmental and Comparative Immunology, 2019
Cytotoxic morula cells (MCs) and phagocytes are the circulating immunocytes of the colonial ascidian Botryllus schlosseri: Both these cells can synthesise amyloid fibrils, supporting the idea that physiological amyloidogenesis is involved in inflammation
