Determination of the boundary lipids of sticholysins using tryptophan quenching
Scientific Reports, 2022 Sticholysins are α-pore-forming toxins produced by the sea-anemone Stichodactyla helianthus. These toxins exert their activity by forming pores on sphingomyelin-containing membranes.

Ecology and Evolution, Volume 10, Issue 21, Page 12348-12363, November 2020., 2020 We investigated the abundance and gene expression of scavenger receptors and thrombospondin‐type‐1 repeat protein superfamily, known to be involved in symbiont recognition, in three plastid‐bearing sea slugs. We could identify candidate receptors, similar to those found in cnidarians for Symbiodinium recognition, that might be relevant in plastid ...

Revista de Investigaciones Marinas, 2023 Sticholisina II (St II) es una citolisina aislada de la anémona marina Stichodactyla helianthus. Esta proteína hidrofilica forma poros en las membranas celulares, lo que provoca el desbalance osmótico que conduce a la lisis celular.

Functional characterization of sticholysin I and W111C mutant reveals the sequence of the actinoporin's pore assembly. [PDF]
PLoS ONE, 2014 The use of pore-forming toxins in the construction of immunotoxins against tumour cells is an alternative for cancer therapy. In this protein family one of the most potent toxins are the actinoporins, cytolysins from sea anemones.

Sea Anemones: Quiet Achievers in the Field of Peptide Toxins
Toxins, 2018 Sea anemones have been understudied as a source of peptide and protein toxins, with relatively few examined as a source of new pharmacological tools or therapeutic leads. This is surprising given the success of some anemone peptides that have been tested,

BioMed Research International, Volume 2017, Issue 1, 2017., 2017 Many studies have comprehensively examined the venom of Ophiophagus hannah snake. Its venom comprises different compounds exhibiting a wide range of pharmacological activities. In this investigation, four peptide fractions (PFs), ranging from 3 kDa to 10 kDa, isolated from the Vietnamese snake venom of O.

BioMed Research International, Volume 2016, Issue 1, 2016., 2016 In the last few years, marine species have been investigated for the presence of natural products with anticancer activity. Using reversed phase chromatography, low molecular weight proteins were fractionated from the sea anemone Anemonia viridis. Four different fractions were evaluated for their cytotoxic activity by means of erythrocyte haemolysis ...

Mediators of Inflammation, Volume 2015, Issue 1, 2015., 2015 Delayed rectifier K+‐channels (Kv1.3) are predominantly expressed in T lymphocytes. Based on patch‐clamp studies, the channels play crucial roles in facilitating the calcium influx necessary to trigger lymphocyte activation and proliferation. Using selective channel inhibitors in experimental animal models, in vivo studies then revealed the clinically ...
