The complement system of Botryllus schlosseri [PDF]

open access: yes, 2017
Among 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 its roots in the evolution is useful to understand how the main complement-related ...

Whole body regeneration and developmental competition in two botryllid ascidians

open access: yesEvoDevo, 2021
Background Botryllid ascidians are a group of marine invertebrate chordates that are colonial and grow by repeated rounds of asexual reproduction to form a colony of individual bodies, called zooids, linked by a common vascular network.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Unconventional secretion of a rhamnose-binding lectin by Botryllus schlosseri phagocytes

open access: yesThe European Zoological Journal
Botryllus schlosseri is a colonial tunicate diffuse in shallow waters of all seas and oceans. When B. schlosseri haemocytes are challenged with nonself, circulating phagocytes respond to the recognition of foreign molecules with the synthesis and ...

Fission in a colonial marine invertebrate signifies unique life history strategies rather than being a demographic trait

open access: yesScientific Reports, 2022
Each of the few known life-history strategies (e.g., r/K and parity [semelparity and iteroparity]), is a composite stratagem, signified by co-evolved sets of trade-offs with stochastically distributed variations that do not form novel structured ...

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, Volume 35, Issue 30, July 24, 2025.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Morula cells and non-self recognition in the compound ascidian Botryllus schlosseri [PDF]

open access: yesInvertebrate Survival Journal, 2005
In the ascidian Botryllus schlosseri, we studied the effects of hemocyte incubation with foreign cells, such as bacteria, bacterial spores and yeast. In the presence of yeast and bacterial spores, morula cells, a common cell type in botryllid ascidians ...
