Novel rhamnose-binding lectins from the colonial ascidian Botryllus schlosseri
Developmental & Comparative Immunology, 2008In a full-length cDNA library from the compound ascidian Botryllus schlosseri, we identified, by BLAST search against UniProt database, five transcripts, each with complete coding sequence, homologous to known rhamnose-binding lectins (RBLs). Comparisons of the predicted amino acid sequences suggest that they represent different isoforms of a novel RBL,

Cellular aspects of allorecognition in the compound ascidian Botryllus schlosseri
Developmental & Comparative Immunology, 2004We studied changes in the morphology of morula cells, a common haemocyte type in botryllid ascidians, during both the rejection reaction (occurring between contacting, genetically incompatible colonies) and fusion (occurring between compatible colonies), and in short-term cultures of haemocytes incubated with heterologous or autologous blood plasma.

The complement system in Botryllus schlosseri
2017Among the various effector mechanisms involved in immune responses, the complement system is one of the most ancient, deeply-rooted and important for its ability to orchestrate different cells and factors of both innate and adaptive immunity. The comprehension of the evolution of the main complement components can provide clues to understand changes ...

Phagocytosis-induced apoptosis in the compound ascidian Botryllus schlosseri.
2014Colonies of the ascidian Botryllus schlosseri contain three blastogenetic generations: functional zooids, their buds and budlets on buds. Generation change or take-over (TO) occur cyclically and assure the recurrent renewal of the colony. During these events, lasting 24-36 h, diffuse apoptosis occurs in zooid tissues, as indicated by morphological ...

Cooperazione tra immunociti nell'ascidia coloniale Botryllus schlosseri
2004Nell’ascidia Botryllus schlosseri abbiamo studiato gli effetti conseguenti all’esposizione in vitro degli emociti con cellule estranee, quali spore batteriche e cellule di lievito. In queste condizioni le cellule a morula, un tipodi emociti comune nei botrillidi, modificano la propria morfologia, rilasciano l’enzima fenolossidasi nel mezzo determinando

Preliminary studies of the complement system in Botryllus schlosseri.
2012The complement system represents an important humoral component of the mammalian immune system. Complement components can be subdivided in 5 gene families: C3/C4/C5, Bf/C2, MASP/C1r-s, C6/C7/C8A/C8B/C9 and Factor I. Until 1884, it was generally believed that the complement system was an unique feature of vertebrates since all attempts to identify ...

Modeling of semelparous/iteroparous polymorphism in Botryllus Schlosseri
2010This thesis describes and models the age of first sexual reproduction in Botryllus schlosseri. B. schlosseri is a sessile, colonial fouling organism that lives mainly in the low intertidal zone of temperate waters. In Eel Pond, Woods Hole, Massachusetts, semelparous (reproduces only once) and iteroparous (reproduces several times) morphs apparently co ...
