Recently Barr et al. (2011) defined four major trout B cell subsets present during terminal B cell differentiation in rainbow trout spleen using the transcription factor XbpI, concluding that trout B cells follow a highly conserved activation pathway, albeit slower than that observed in mammalian species. M. Page 27 27 and Irwin 1985; Irwin and Kaattari 1986; Zapata and Cooper 1990; Zwollo et al. 2005; 2008) and IgM-secreting cells are generated in LPS-activated cultures derived from splenic B cells (Bromage et al.

The thymoids were found in the tips of the gill filaments and the neighbouring secondary lamellae (both within the gill basket) of lamprey larvae. Only in the thymoids the an expression of the orthologue of the gene encoding forkhead box N1 (FoxN1), a marker of the thymopoietic microenvironment in jawed vertebrates, accompanied by expression of genes encoding type A variable lymphocyte receptors (VLRA) and cytosine deaminase 1 (CDA1), found (Bajoghli et al. 2011). The thymus first appears as an identifiable organ in the chondrichthyes and osteichthyes (Rasmussen and Arnason 1999) and its emergence in evolution parallels the appearance of a VDJ recombination as a novel means of somatically diversifying antigen receptors (Boehm and Bleul 2007).

The adaptive immune system, by its very nature of developing more sophisticated antigen-specific defences, and taking into consideration the low temperature environment of these fish, is much slower to initiate and may take weeks to months to develop. This makes the innate immune system of utmost importance if a host is to survive primary stages of infection with a pathogen and be able to tailor a specific adaptive response that facilitates pathogen killing and clearance. Our understanding of functional development and elicitation of adaptive responses in teleost fish is predominantly derived from molecular and immunohistochemical characterization of adaptive markers and by inference from the wealth of understanding of mammalian adaptive systems.
