Open AccessEvolution of Th2 responses: characterization of IL-4/13 in sea bass (Dicentrarchus labrax L.) and studies of expression and biological activity
Th2 immunity is a primary host defence against metazoan pathogens and two of the important cytokines involved in this immune response in mammals are IL-4 and IL-13. Recently the origin and evolution of Th2 imm...

Open AccessImmunoglobulin T from sea bass (Dicentrarchus labrax L.): molecular characterization, tissue localization and expression after nodavirus infection
Immunoglobulins (Igs) are fundamental components of the adaptive immune system of vertebrates, with the IgT/IgZ isotype specific of Teleosts. In this paper we describe the identification of an IgT heavy chain ...

The cytokine IL-1β from the crocodile icefish Chionodraco hamatus (Perciformes: Channichthyidae)
The immune system of the so-called crocodile icefishes, members of the family Channichthyidae, has been recently investigated to study its morphological and functional organisation, to evidence the presence of...

Biological Activity of Sea Bass (Dicentrarchus labrax L.) Recombinant Interleukin-1β
Biological activities of a putative mature sea bass interleukin-1β peptide, produced as a recombinant protein (rIL-1β) in Escherichia coli, have been investigated. The rIL-1β contains a 6-...

Expression in Escherchia coli and Purification of Sea Bass (Dicentrarchus labrax) Interleukin 1β, a Possible Immunoadjuvant in Aquaculture
Interleukin 1β (IL-1β) is a pleiotropic cytokine that plays a pivotal role in regulating immune responses. Our group has recently cloned IL-1β from sea bass (Dicentrarchus labrax), one of the main Mediterranean a...
