The complement system in Botryllus schlosseri [PDF]

, 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 the evolution of the main complement components can provide clues to understand changes ...

Speed vs completeness: a comparative study of solitary and colonial tunicate embryogenesis [PDF]

Frontiers in Cell and Developmental Biology
Solitary ascidians, such as Ciona robusta, have been used for over a century as model systems for embryological studies. These species are oviparous, producing many relatively small and transparent eggs, which are released and fertilized outside the ...

Proteome-Wide 4-Hydroxy-2-Nonenal Signature of Oxidative Stress in the Marine Invasive Tunicate Botryllus schlosseri. [PDF]

Proteomics
ABSTRACT The ascidian Boytryllus schlosseri is a marine chordate that thrives under conditions of anthropogenic climate change. The B. schlosseri expressed proteome contains unusually high levels of proteins adducted with 4‐hydroxy‐2‐nonenal (HNE). HNE represents a prominent posttranslational modification resulting from oxidative stress.

Aging in the colonial chordate, Botryllus schlosseri. [PDF]

Invertebr Reprod Dev, 2015
What mechanisms underlie aging? One theory, the wear-and-tear model, attributes aging to progressive deterioration in the molecular and cellular machinery which eventually lead to death through the disruption of physiological homeostasis. The second suggests that life span is genetically programmed, and aging may be derived from intrinsic processes ...

Histocompatibility in Botryllus schlosseri and the origins of adaptive immunity. [PDF]

Immunogenetics
Abstract The basal chordate, Botryllus schlosseri , undergoes a natural transplantation reaction that is controlled by a single, highly polymorphic locus called the fuhc .

Mechanical resilience of the sessile tunicate Botryllus schlosseri.

J Exp Biol, 2023
ABSTRACT We demonstrate that the sessile tunicate Botryllus schlosseri is remarkably resilient to applied loads by attaching the animals to an extensile substrate subjected to quasistatic equiradial loads. Animals can withstand radial extension of the substrate to strain values as high as 20% before they spontaneously detach.

Extensive Fouling of Eelgrass (<i>Zostera marina</i> L.) Reproductive Shoots by Invasive Tunicates-A Potential Threat to Meadow Reproductive Output? [PDF]

Ecol Evol
Here, we document through field observations and photographs, the extensive fouling of seed‐bearing Z. marina reproductive shoots by invasive tunicates in a Cape Cod meadow during late spring/early summer 2025. Such fouling may block seed release and/or inhibit dispersal which may reduce meadow reproductive success.

Urochordate histoincompatible interactions activate vertebrate-like coagulation system components. [PDF]

PLoS ONE, 2008
The colonial ascidian Botryllus schlosseri expresses a unique allorecognition system. When two histoincompatible Botryllus colonies come into direct contact, they develop an inflammatory-like rejection response.

Transcriptome dynamics in the asexual cycle of the chordate Botryllus schlosseri. [PDF]

BMC Genomics, 2016
We performed an analysis of the transcriptome during the blastogenesis of the chordate Botryllus schlosseri, focusing in particular on genes involved in cell death by apoptosis. The tunicate B. schlosseri is an ascidian forming colonies characterized by the coexistence of three blastogenetic generations: filter-feeding adults, buds on adults, and ...

Whole-mount fluorescent in situ hybridization staining of the colonial tunicate Botryllus schlosseri. [PDF]

Genesis, 2015
Botryllus schlosseri is a colonial ascidian with characteristics that make it an attractive model for studying immunology, stem cell biology, evolutionary biology, and regeneration.
