Adaptive Immunity = Specific, acquired immunity. The Atlantic cod does, however, contain more genes related to the MHC I component of the immune system, as well as the expansion of some TLR clades, compared to other vertebrates, which may help compensate for the missing MHC II and CD4 (87, 220). Once recognized, the innate immune cell will become activated and can participate in several responses depending on their cell subtype including, but not limited to, phagocytosis and subsequent destruction of the pathogen, production of various cytokines and activation of the adaptive immune system via antigen presentation along with cytokine stimulation.

Due to an alternative splicing pathway, the transmembrane form of IgM is one domain shorter than the secreted form in teleost fish, resulting in a shortened IgM receptor on the B cell surface (178). Fast MD, Sims DE, Burka JF, Mustafa A, Ross NW. While tetrapods contain a single CD4 molecule with four Ig domains, two types of CD4 molecules have been described in bony fish: CD4-1 containing four Ig domains and CD4-2 which contains either two or three Ig domains, depending on the species (255). doi: 10.1002/jez.10124, 24. Affinity maturation is generated during immune responses in bony fish, as evidenced by the replacement of low-affinity Ab by intermediate-affinity Ab and eventually by high-affinity Ab in rainbow trout (229). Criscitiello MF. Boshra H, Li J, Sunyer JO. Moreover, innate immunity is present at birth, while adaptive immunity … J Immunol.

Studies in shark, skate, lungfish and teleost fish have demonstrated both ROS and NO production in various leukocytes (65, 101). (2005) 57:458–63. (surface barriers) Adaptive immunity is specific defense and has a delayed response. Innate immunity provides the first line defense against pathogens through physical and chemical barriers such as skin, mucus layers, and saliva. (2012) 2012:853470. doi: 10.5402/2012/853470, 17. Saliva, tears, skin, mucus linings, stomach acid, and some of the bacteria in the gut serve as barriers, preventing the entering of pathogens to the tissues of the body. By MHC class I and MHC class II molecules. Characterization of a divergent non-classical MHC class I gene in sharks. The Actinopterygii have fins that are composed of webs of skin supported by bony spines, known as lepidotrichia. Both bony and cartilaginous fish lack bone marrow, the main site of hematopoiesis in mammals, and germinal centers (GC), specialized sites where mature B cells proliferate, differentiate, and selection of high affinity BCR occurs in mammals.

New insights into the evolution of IFNs: zebrafish group II IFNs induce a rapid and transient expression of IFN-dependent genes and display powerful antiviral activities. Dietary administration of probiotics to the gilthead seabream (Sparus aurata) enhanced the intestinal microbiota and increased expression of various immune genes in the intestine including MHCII and TNF-α, while administration of probiotics to the Nile Tilapia (Oreochromis niloticus) and rainbow trout promoted greater development of the intestine, as measured by villous height, and increased the population of intestinal granulocytes (39–41). Innate Immunity: Innate immunity does not produce allergic reactions. (2011) 6:e18832. Catfish and zebrafish AID have been demonstrated to mediate SHM in mouse fibroblasts (NIH3T3PI19) (225), while zebrafish AID can efficiently deaminate methylated deoxycytidines (226). Modified from Criscitiello et al. J Immunol. The clusters can be repeated as many as 100 times in the genome, depending on the species. T cells are classified into 2 main populations: CD8+ cytotoxic T-cells (Tc) which interact with MHC class I and CD4+ helper T cells (Th) which interact with MHC class II. (2002) 54:570–81. The African coelacanth genome provides insights into tetrapod evolution. While the innate immune system is assumed to have arisen >600 million years ago (MYA), specific components of the adaptive immune system, including immunoglobulins (Igs), T cell receptors (TCR), and major histocompatibility complex (MHC), are comparatively newer and are assumed to have arisen approximately 450 MYA in the first jawed vertebrates (i.e., Gnathostomata) (3–5). doi: 10.1093/intimm/dxh347, 226. This c-type lysozyme was characterized in the nurse shark and found to hydrolyze the cell wall of M. lysodeikticus and inhibit the growth of Gram-positive bacteria, suggesting a similar function for lysozyme as in teleost fish and higher vertebrates (129). Comparative studies in fish such as those discussed here are essential for developing a comprehensive understanding of the evolution of the immune system. PLoS ONE. The evolution of multiple isotypic IgM heavy chain genes in the shark. Proc Natl Acad Sci USA. (2002) 169:2488–97. However, not all fish species contain all three pathways. Lysozyme is a lytic enzyme that acts on the peptidoglycan layer of bacterial cell walls by hydrolyzing 1–4 β-linked glycoside bonds resulting in lysis of the bacterium. doi: 10.1002/(SICI)1097-010X(19960601/15)275:2/3<125::AID-JEZ6>3.0.CO;2-F, 216.

In addition, two g-type lysozyme genes were discovered in the coelacanth genome, although no functional studies on lysozymes have been completed in coelacanth or lungfish to date (130). (1997) 61:141–6. In most bony fish characterized to date, IgT/Z contain four C domains, although this is known to vary in a number of species (204–206). Teleost fish contain many forms of IgD, with constant domains ranging from 2 to 16 (191–193). Zapata AG, Torroba M, SacedÃ3n R, Varas A, Vicente A. doi: 10.4049/jimmunol.175.4.2484, 282. Difference between Innate and Adaptive Immunity. Characterization of γδ T cells from zebrafish provides insights into their important role in adaptive humoral immunity. Adaptive Immunity: Adaptive immunity exhibits a higher potency. CD8+ T cells are activated by peptides presented via MHC-I molecules and secrete cytotoxins such as perforin and granzymes that initiate apoptosis in the target cells. The function of IgW and IgD, however, is poorly understood in both fish and mammals. (2012) 336:1268–73. Innate immunity and adaptive immunity are the two categories of the immune system of animals. The results demonstrated that, following immunization, pentameric IgM, which localizes mainly in the plasma, was induced before other isotypes, but with a low-affinity interaction with antigens.

Thus here, we will endeavor to provide a comprehensive comparison of the innate and adaptive immune systems in cartilaginous fish, lobe-finned fish (focusing on coelacanths and lungfish), and ray-finned fish, with a focus on Teleost fish. Unprecedented multiplicity of Ig transmembrane and secretory mRNA forms in the cartilaginous fish. Innate Immunity: Adaptive Immunity: Specificity: Non-specific: Highly specific: Action: For structures shared by a group of microbes: For special antigens of microbial and non-microbial agents: Used against: For microbes: Microbes and non-microbial substances called antigens: Memory: No memory: Long term memory : … Various types of phagocytes serve as internal barriers, preventing the growth and reproduction of pathogens inside the tissues. Immunobiology of the Shark. 2. Inoue JG, Miya M, Lam K, Tay BH, Danks JA, Bell J, et al. Front Immunol. Identification and bioactivities of IFN-γ in rainbow trout Oncorhynchus mykiss: the first Th1-type cytokine characterized functionally in fish. Innate Immunity: Innate immunity is always present in the body. (2016) 8:3508–15. doi: 10.1016/j.dci.2004.05.005, 225. doi: 10.1016/j.fsi.2004.09.006, 16. doi: 10.1016/j.fsi.2017.03.037, 152. These studies in different fish classes/subclasses suggest that some components of the complement system are evolutionarily conserved and similar to those of higher vertebrates (102).
