Inflammatory Response of the Ascidian Ciona intestinalis
Abstract The Ciona intestinalis inflammatory response to several irritants appears to be composed of a complex reaction set. The cellular reactions in the tunic involve hemocyte infiltration, hemocyte and epidermis activities, vacuolization, and cell disruption, while cell products can contribute to form capsule components and/or cause a tunic wound. In this response, the involvement of the pharynx, as the main immune-competent organ, has been disclosed by a lipopolysaccharide challenge that upregulates innate immunity genes and transcription activation genes. The pharynx responds through hemocyte recruitment into the pharynx vessels, enhancement of galectin-like lectins in the serum hemoly…
Biological activities of the extracts from macroalgae Carpodesmia crinita, Carpodesmia brachycarpa, Asparagopsis taxiformis
Marine species represent a rich source of biologically active products that can be used in various fields. Among them, marine algae produce numerous secondary metabolites responsible for different biological activities such as: immunomodulatory [1], antioxidant [2], and antimicrobial [3]. The aim of this study was chemically characterizing the extracts of three macroalgae species: Carpodesmia crinite (Duby) Orellana & Sansón, 2019, Carpodesmia brachycarpa (J. Agardh) Orellana & Sansón 2019, Asparagopsis taxiformis (Delile) Trevisan 1845 and evaluate their biological activities. The characterization of the secondary metabolites was performed by HPLC-MS and the results obtained showed…
