Isolation of a novel LPS-induced component of the ML superfamily in Ciona intestinalis
2015
ML superfamily represents a group of proteins playing important roles in lipid metabolism and innate immune response. In this study, we report the identification of the first component of the ML superfamily in the invertebrate Ciona intestinalis by means of a subtractive hybridization strategy. Sequence homology and phylogenetic analysis showed that this protein forms a specific clade with vertebrate components of the Niemann-Pick type C2 protein and, for this reason, it has been named Ci-NPC2. The putative Ci-NPC2 is a 150 amino acids long protein with a short signal peptide, seven cysteine residues, three putative lipid binding site and a three-dimensional model showing a characteristic b…

cytokines in the inflammatory response of the ascidian ciona intestinalis
2015
The Ciona intestinalis inflammatory response to several irritants have been demonstrated to be composed of a complex set reaction. The cellular reactions involve hemocyte infiltration, hemocyte and epidermis activities, vacuolization, cell disruption, while cell products can contribute to form capsule components and/or cause a wound. In this response the involvement of the pharynx, as the main immune-competent organ, has been disclosed by lipopolysaccharide (LPS) challenge that upregulates innate immunity genes. In vertebrate cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and responsiveness of cell populations that h…
Inflammatory hemocytes in Ciona intestinalis innate immune response
2009
In the present paper an attempt is carried out to revise Ciona intestinalis inflammatory hemocytes according to their morphology as formerly observed by light and electron microscopy, and taking in account recent reports on innate immunity gene expression. We also examine hemocyte morphofunctional aspects as derived from previous papers that refer to the tunic and body wall inflammatory responses challenged by corpusculate or soluble agents. LPS inoculation into the body wall or treating hemocytes in vitro with LPS have also been taken in account. LPS inoculation stimulated the expression of CiTNF alpha, CiFACIT- alpha chain collagen, CiC3a, CiCD94 and enhanced phenoloxidase activity. These…

Characterization and transcription studies of a phytochelatin synthase gene from the solitary tunicate Ciona intestinalis exposed to cadmium.

The major thiol-containing molecules involved in controlling the level of intracellular ROS in eukaryotes, acting as a nonenzymatic detoxification system, are metallothioneins (MTs), glutathione (GSH) and phytochelatins (PCs). Both MTs and GSH are well-known in the animal kingdom. PC was considered a prerogative of the plant kingdom but, in 2001, a phytochelatin synthase (PCS) gene was described in the nematode Caenorhabditis elegans; additional genes encoding this enzyme were later described in the earthworm Eisenia fetida and in the parasitic nematode Schistosoma mansoni but scanty data are available, up to now, for Deuterostomes. Here, we describe the molecular characteristics and transc…
