Comp Biochem Physiol A Comp Physiol. Adaptive Immunity has Virology. Initiation of the innate immune response begins when germline-encoded intracellular or extracellular pattern recognition receptors (PRRs) of an immune cell bind to a PAMP found on a pathogen, such as bacteria-derived LPS, viral RNA, bacterial DNA, or a danger-associated molecular pattern (DAMP) found on proteins or other biomolecules that are released from stressed cells or injured cells. Results Probl Cell Differ. Adaptive Immunity: Adaptive immunity only occurs in response to exposure to an external factor. Recombinant (r-) c-type and g-type lysozymes have been found to have high bacteriolytic activity against a variety of pathogens of teleost fish such as V. anguillarum, Aeromonas hydrophila, and Micrococcus lysodeikticus (125, 126).

IgH genes in lungfish are organized in a transiting form, having both cluster (like cartilaginous fish) and translocon (like teleost fish) configurations (160). They are subdivided into two classes, the Actinopterygii (ray-finned fish) and the Sarcopterygii (lobe-finned fish) (Figure 1). (2006) 109:183–7. In: Malagoli, editor. Adaptive immunity uses a more specific ray of pathogens & receptors but detects the same way innate immunity does. Two rounds of genome duplication (1R and 2R) are thought to have occurred early in vertebrate evolution, before the Cyclostome/Gnathostome divergence, ~500–800 MYA (Figure 1) (10, 11).

In addition, while the gut microbiome of some shark species has been identified (47), it is unknown how the microbiota effects the development of the GALT and its immune response in both cartilaginous fish and lobe-finned fish. The development of antibodies that specifically detect fish proteins, such as CD4 and CD8, is necessary to fully understand the homing and recirculation of B and T cells in fish. **Absence of mannose-binding lectin (MBL), ficolin, C1qA, and C1qC from genomes of any cartilaginous fish studied to date ***MASP2 transcript with no serine protease domain in hammerhead shark genome; MASP2 missing from elephant shark, little skate, and catshark genomes (102–109).

Due to its ability to respond to a large number of pathogens, adaptive immunity is considered as possessing a higher diversity. (2003) 23:601–12. This study also demonstrated that, following intestinal parasitic infection, the number of IgT+ B cells increased in the gut, but the number of IgM+ B cells in the gut did not change (207). doi: 10.1073/pnas.0538029100, 186.

Large accumulations of lymphoid cells have been found in the gut of the Australian lungfish (Neoceratodus forsteri); however the cellular and molecular composition of these lymphoid masses is currently unknown (46).

The genes for TCR-α, β, γ, and δ are diversified using V(D)J rearrangement and have been identified in teleost fish, cartilaginous fish, and coelacanths (173, 255, 257, 258). Sequences with homology to IL-10 were found in the spiny dogfish (S. acanthias), elephant shark, and coelacanth genomes (173, 275). Nature.

(2014) 505:174–9. One copy of the IL-10 gene, produced by Treg cells, is found in most species of teleost fish, although two copies have been identified in rainbow trout and European common carp (291, 292). (2011) 31:644–54. The external defense serves as the first line defense against pathogens, and it is achieved by the physical and chemical barriers. Boca Raton, FL: CRC Press (2014). Nat Rev Immunol. For example, B cells and T cells have been identified in the gills of rainbow trout (Oncorhynchus mykiss) and channel catfish (Ictalurus punctatus) while a specific B cell Ig transcript was observed in the gills of nurse shark (see adaptive immune section for a discussion on B cells, Ig, and T cells). Several of these AMPs have been cloned and subsequent functional studies have demonstrated antiviral and antibacterial activities against a variety of pathogens, demonstrating that AMPs from teleost fish exhibit many if not all of the characteristics of other vertebrate AMPs (131–134).

Always a model system, today as yesterday. In: Molecular Biology of the Cell. T cells have also been identified in the GALT of several teleost species (32–34). The mammalian complement system is composed of ~30 proteins that make up three activation pathways: the classical pathway, activated by antibody-antigen complexes and thus a bridge between innate and adaptive immunity; the alternative pathway, which is independent of antibodies and activated directly by pathogens; and the lectin pathway which is activated by the binding of the mannose-binding lectin (MBL), or ficolin, to mannose (or other sugar) residues present on the pathogen surface (102). In addition to TLRs, differences in several other PRRs between ray-finned, lobe-finned and cartilaginous fish have been noted. Annu Rev Immunol.

Antigens that are to be presented by MHC I are processed via the immunoproteasome and transferred to the endoplasmic reticulum (ER) by transporter associated with antigen processing (TAP) where they associate with MHC I and are eventually transported to the cell membrane. Lee PT, Bird S, Zou J, Martin SAM. Flajnik MF. The secretion of EVs was not induced by CpG in a splenocyte culture (containing mostly B cells) suggesting that the EVs were likely produced by macrophages or dendritic cells in the head kidney leukocyte culture (64).
