Hymeraphia vaceleti Morrow & Allcock & Mccormack 2018, sp. nov.
No full text<i>Hymeraphia vaceleti</i> sp. nov. Morrow <p>(Figure 3 a–b)</p> <p> <b>Material examined:</b> The holotype of <i>Hymeraphia vaceleti</i> <b>sp. nov.</b> (BELUM Mc2018.1) was collected during cruise CE13008, R.V. <i>Celtic Explorer</i> using the ROV <i>Holland I</i>, southwest off Ireland, 48.583, -10.46, 14/06/2013, 1541 m depth.</p> <p> <b>Diagnosis:</b> <i>Hymeraphia</i> with markedly bent acanthostyles with a large crown of stellate spines at their distal end.</p> <p> Holotype description: Thin encrustation measuring 8mm x 5 mm x 1.5 mm, growing on dead <i>Desmophyllum pertusum</i> (Linnaeus, 1758). Long tylostyles project through surface giving hispid appearance. Consistency soft and compressible. Colour white in ethanol.</p> <p>Skeleton: Choanosomal skeleton with hymedesmoid arrangement consisting of a basal membrane attached to substratum, bases of echinating acanthostyles and long tylostyles embedded in membrane and arranged perpendicular to it. Long tylostyles protrude a long way through ectosome, surrounded by bouquets of very fine hair-like, ectosomal styles.</p> <p> Spicules: Tylostyles are long and thin, gently curving and tapering to a fine point, with an asymmetric base, occasionally base is subtylote (125– <i>690</i> – 2000 x 7– <i>10</i> –12 µm n=3). Echinating acanthostyles have a markedly bent, slightly inflated smooth base, base frequently subtylote. Distal ends of acanthostyles have a large stellate crown composed of approximately 16 spines (acanthostyle length = 57– <i>69</i> –83 µm; base = 7– <i>10</i> –12.5 µm; crown = 12– <i>29</i> –45 µm n =20). Ectosomal styles, very fine and hair-like (340– <i>415</i> –460 µm x 1–2 µm n=20). See Fig. 2 for spicule morphology and Table 2 for spicule dimensions.</p> <p> <b>Etymology:</b> The specific epithet <i>vaceleti</i> is given in honour of our dear friend and colleague, Dr. Jean Vacelet, for the friendship and encouragement he has consistently shown and for his overwhelming contribution to sponge science.</p> <p> <b>Remarks:</b> <i>Hymeraphia vaceleti</i> <b>sp. nov.</b> differs from other species of <i>Hymeraphia</i> by the distinctive acanthostyles which are shorter than those of the other congeners and have a much larger stellate crown of spines. The shaft of the acanthostyle is markedly bent just above the tylote base (Table 1).</p>Published as part of <i>Morrow, Christine, Allcock, Louise A. & Mccormack, Grace, 2018, A new species of Hymeraphia Bowerbank, 1864 (Axinellida: Raspailiidae) from a deep-water canyon southwest off Ireland, pp. 61-68 in Zootaxa 4466 (1)</i> on page 64, DOI: 10.11646/zootaxa.4466.1.7, <a href="http://zenodo.org/record/1442108">http://zenodo.org/record/1442108</a>

Immunomodulatory properties of characellide A on human peripheral blood mononuclear cells.
No full textMarine sponges and their associated microbiota are multicellular animals known to produce metabolites with interesting pharmacological properties playing a pivotal role against a plethora of pathologic disorders such as inflammation, cancer and infections. Characellide A and B belong to a novel class of glycolipopeptides isolated from the deep sea marine sponge Characella pachastrelloides. In this study, we have evaluated the effects of characellide A and B on cytokine and chemokine release from human peripheral blood mononuclear cells (PBMC). Characellide A induces a concentration- and time-dependent CXCL8, IL-6 and TNF-α release from PBMC. This production is mediated by the induction of gene transcription. Moreover, cytokine/chemokine release induced by characellide A from PBMC is CD1d-dependent because a CD1d antagonist, 1,2-bis(diphenylphosphino)ethane [DPPE]-polyethylene glycolmonomethylether [PEG], specifically inhibits characellide A-induced activation of PBMC. In conclusion, characellide A is a novel modulator of adaptative/innate immune responses. Further studies are needed to understand its potential pharmacological application
