Heat Stress Drives Rapid Viral and Antiviral Innate Immunity Activation in Hexacorallia [PDF]

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT The class Hexacorallia, encompassing stony corals and sea anemones, plays a critical role in marine ecosystems. Coral bleaching, the disruption of the symbiosis between stony corals and zooxanthellate algae, is driven by seawater warming and further exacerbated by pathogenic microbes.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux [PDF]

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

L’anémone de merNematostella vectensis [PDF]

médecine/sciences, 2021
Nematostella, petite anémone de mer, possède de fascinantes propriétés, telles que la régénération du corps entier, l’absence de signes de vieillissement et d’affections liées à l’âge comme, par exemple, le développement de cancers. Elle se cultive aisément et se reproduit en laboratoire.

Functional conservation of Nematostella Wnts in canonical and noncanonical Wnt-signaling [PDF]

Biology Open, 2011
Summary Cnidarians surprise by the completeness of Wnt gene subfamilies (11) expressed in an overlapping pattern along the anterior-posterior axis. While the functional conservation of canonical Wnt-signaling components in cnidarian gastrulation and ...

Functional characterization of specialized immune cells in a cnidarian reveals an ancestral antiviral program

Nature Communications
Examining early-branching animal phyla can help reconstruct the evolutionary origins of immune cells. Here, we characterize immune-related cell programs in embryos of the sea anemone Nematostella vectensis, a model of Cnidaria, which diverged ~600 ...

MAPK signaling is necessary for neurogenesis in Nematostella vectensis [PDF]

BMC Biology, 2016
The nerve net of Nematostella is generated using a conserved cascade of neurogenic transcription factors. For example, NvashA, a homolog of the achaete-scute family of basic helix-loop-helix transcription factors, is necessary and sufficient to specify a subset of embryonic neurons. However, positive regulators required for the expression of neurogenic

Contribution of Maternal and Paternal Transmission to Bacterial Colonization in Nematostella vectensis [PDF]

Frontiers in Microbiology, 2021
Microbial communities confer multiple beneficial effects to their multicellular hosts. To evaluate the evolutionary and ecological implications of the animal-microbe interactions, it is essential to understand how bacterial colonization is secured and maintained during the transition from one generation to the next.

Transcriptomic Analysis in the Sea Anemone Nematostella vectensis [PDF]

, 2020
The sea anemone Nematostella vectensis is an emerging research model to study embryonic development and regeneration at the molecular and global transcriptomic level. Transcriptomics analysis is now routinely used to detect differential expression at the genome level.

Cellular pathways during spawning induction in the starlet sea anemone Nematostella vectensis

Scientific Reports, 2021
In cnidarians, long-term ecological success relies on sexual reproduction. The sea anemone Nematostella vectensis, which has emerged as an important model organism for developmental studies, can be induced for spawning by temperature elevation and light ...

Some like it hot: population-specific adaptations in venom production to abiotic stressors in a widely distributed cnidarian

BMC Biology, 2020
Background In cnidarians, antagonistic interactions with predators and prey are mediated by their venom, whose synthesis may be metabolically expensive.
