Bela-Ong DB, Kim J, Thompson KD, Jung TS. Leveraging the biotechnological promise of the hagfish variable lymphocyte receptors: tools for aquatic microbial diseases. FISH & SHELLFISH IMMUNOLOGY 2024; 150:109565. [PMID: 38636740 DOI: 10.1016/j.fsi.2024.109565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/02/2024] [Accepted: 04/15/2024] [Indexed: 04/20/2024]
Abstract
The jawless vertebrates (agnathans/cyclostomes) are ancestral animals comprising lampreys and hagfishes as the only extant representatives. They possess an alternative adaptive immune system (AIS) that uses leucine-rich repeats (LRR)-based variable lymphocyte receptors (VLRs) instead of the immunoglobulin (Ig)-based antigen receptors of jawed vertebrates (gnathostomes). The different VLR types are expressed on agnathan lymphocytes and functionally resemble gnathostome antigen receptors. In particular, VLRB is functionally similar to the B cell receptor and is expressed and secreted by B-like lymphocytes as VLRB antibodies that bind antigens with high affinity and specificity. The potential repertoire scale of VLR-based antigen receptors is believed to be at least comparable to that of Ig-based systems. VLR proteins inherently possess characteristics that render them excellent candidates for biotechnological development, including tractability to recombinant approaches. In recent years, scientists have explored the biotechnological development and utility of VLRB proteins as alternatives to conventional mammalian antibodies. The VLRB antibody platform represents a non-traditional approach to generating a highly diverse repertoire of unique antibodies. In this review, we first describe some aspects of the biology of the AIS of the jawless vertebrates, which recognizes antigens by means of unique receptors. We then summarize reports on the development of VLRB-based antibodies and their applications, particularly those from the inshore hagfish (Eptatretus burgeri) and their potential uses to address microbial diseases in aquaculture. Hagfish VLRB antibodies (we call Ccombodies) are being developed and improved, while obstacles to the advancement of the VLRB platform are being addressed to utilize VLRBs effectively as tools in immunology. VLRB antibodies for novel antigen targets are expected to emerge to provide new opportunities to tackle various scientific questions. We anticipate a greater interest in the agnathan AIS in general and particularly in the hagfish AIS for greater elucidation of the evolution of adaptive immunity and its applications to address microbial pathogens in farmed aquatic animals and beyond.

Effects of feeding chicken egg yolk antibodies on intestinal cell apoptosis, oxidative stress and microbial flora of tilapia (Oreochromis niloticus) infected with Streptococcus agalactiae. FISH & SHELLFISH IMMUNOLOGY 2024; 150:109596.

Abstract
Streptococcosis, the most common bacterial disease of fish in recent years, is highly infectious and lethal, and has become an important factor hindering the healthy and sustainable development of aquaculture. Chicken egg yolk antibody (IgY) has the advantages of high antigen specificity, inexpensive and easy to obtain, simple preparation, no toxic side effects, and in line with animal welfare, which is a green and safe alternative to antibiotics. In this study, the potential of specific IgY in the treatment of gastrointestinal pathogens was explored by observing the effects of specific IgY on intestinal flora, pathological tissue, apoptosis, oxidative stress, and inflammatory response of tilapia. We used the specific IgY prepared in the early stage to feed tilapia for 10 days, and then the tilapia was challenged with Streptococcus agalactiae. The results showed that feeding IgY before challenge had a small effect on the intestinal flora, and after challenge specific IgY decreased the proportion of Streptococcus and increased the diversity of the intestinal flora; in histopathology, specific IgY decreased tissue damage and maintained the integrity of tissue structure. Further study found that specific IgY can reduce intestinal epithelial cell apoptosis and reduce caspase activity; at the same time, the content of MDA was decreased, and the activities of SOD, CAT, GSH-Px and GR were increased. In addition, specific IgY can down-regulate the expression levels of IL-8 and TNF-α genes and up-regulate the expression levels of IL-10 and TGF-β. The results of this study showed that specific IgY could improve the intestinal flora of tilapia infected with Streptococcus agalactiae, reduce intestinal cell apoptosis, oxidative stress injury and inflammatory response, thereby reducing tissue damage and protecting the health of tilapia. Overall, specific IgY can be further explored as a potential antibiotic alternative for gastrointestinal pathogen infections.

Abstract
Immunization of egg-laying hens with viral antigens efficiently produces large amounts of virus-specific IgY antibodies from egg yolks. A supply of practical and economical antibodies against the rabies virus is being desired worldwide. We immunized hens with the antigen gene DNA of the rabies virus, purified specific IgY antibodies from the egg yolk, and characterized the immuno-protein chemistry for use as a diagnosis. To prepare specific IgY antibodies against rabies virus nucleoprotein (RV-N) by DNA immunization, laying hens were pre-injected with λ-carrageenan or Freund's complete adjuvant to increase local immune activity (pre-immune stimulation), and then immunized with RV-N recombinant plasmid DNA. RV-N-specific IgY antibodies were prepared from egg yolks of immunized hens. For comparison, conventional protein antigen immunization was also used to induce the production of RV-N-specific IgY antibodies. Laying hens were immunized with an RV-N protein antigen and RV-N-specific IgY was purified from egg yolks. The binding activity against RV-N antigens was examined using IgY samples prepared by DNA (with pre-immune stimulation) and protein immunization. Immunohistochemical staining showed that IgY antibodies prepared by protein immunization strongly detected viral antigens in the brain sections of dogs infected with the virus, whereas IgY antibodies prepared by DNA immunization did not. Enzyme-linked immunosorbent assay was performed using a commercially available rabies vaccine (inactivated virus) treated with 10% formalin and heating (60°C, 30 min and 90°C, 5 min). IgY prepared by DNA immunization had weaker reactivity with denatured antigens and lower antigen concentrations than IgY prepared by protein immunization. These results suggest that it is necessary to develop a DNA immunization method for inducing IgY antibodies against the rabies virus that strongly bind to native and denatured antigens to prepare specific IgYs that can be used for antigen detection in clinical tests.

Abstract
Acute hepatopancreatic necrosis disease (AHPND), caused by a toxin-producing Vibrio parahaemolyticus strain, has become a serious threat to shrimp aquaculture. The need to regulate antibiotic use prompted the development of alternative ways to treat infections in aquaculture including the use of chicken egg yolk immunoglobulin (IgY) for passive immunization. This study evaluated the protective effect of IgY against AHPND infection in Litopenaeus vannamei (Boone). IgY was isolated from eggs laid by hens immunized with recombinant PirA-like (rPirA) and PirB-like (rPirB) toxins. Whole-egg powders having IgY specific to rPirA (anti-PirA-IgY) and rPirB (anti-PirB-IgY) and IgY from non-immunized hen (control-IgY) were mixed with basal diets at 20% concentrations and used to prefeed shrimp 3 days before the bacterial challenge test. Survival rates of the challenged shrimp fed the anti-PirA-IgY, anti-PirB-IgY and control-IgY diets were 86%, 14% and 0%, respectively. Only the feed containing anti-PirA-IgY protected shrimp against AHPND. Increasing the concentration of rPirA antigen to immunize hens and lowering the amount of egg powder in feeds to 10% consistently showed higher survival rates in shrimp fed with anti-PirA-IgY (87%) compared with the control (12%). These results confirm that addition of anti-PirA-IgY in feeds could be an effective prophylactic method against AHPND infection in shrimp.

Abstract
Severe burn injury and cirrhosis often cause the translocation of bacterial endotoxins into blood, leading to systemic damage and even death. Our previous studies have shown that anti‐lipopolysaccharide egg yolk antibody (anti‐LPS IgY) can neutralize bacterial endotoxins in vitro and in vivo effectively, thereby reducing endotoxin damage. Whether anti‐LPS IgY can be absorbed into the blood through the intestinal barrier and neutralize endotoxins in circulation remains unclear. In this study, we used in vivo small animal imaging techniques, protein purification, molecular biology, and mass spectrometry to show that intragastrically administered anti‐LPS IgY is detected in the blood of mice as an intact molecule and has the capacity to bind to LPS. Immunohistochemical analysis confirmed that anti‐LPS IgY is associated with the intestinal mucosa of mice. However, the route of absorption of this large protein molecule was not determined. This study suggests that anti‐LPS IgY can be absorbed into the circulation, with the same molecular mass as purified anti‐LPS IgY as a macromolecular protein, suggesting a new strategy for the prevention of damage caused by endotoxins.

Abstract
Skin ulceration syndrome in sea cucumbers is an infectious bacterial disease with fast and high mortality. This study investigated the protection of chicken egg yolk antibodies (IgY) on skin ulcer syndrome in sea cucumbers induced by intraperitoneally injecting Shewanella marisflavi AP629. Inactivated whole S. marisflavi AP629 cells were used as an immunogen to immunize laying hens. The highest titer of the obtained specific IgY by ELISA was 1:90000. Specific IgY significantly inhibited the growth of S. marisflavi AP629 in a liquid medium, dose-dependent manner at concentrations ranging from 0.5 to 2 mg/mL. Results obtained from scanning electron microscopy and confocal laser scanning microscopy showed that specific IgY could make bacteria agglutinate and damage the cell membrane of S. marisflavi AP629, resulting in a decrease of bacterial viability. Sea cucumbers treated with 25, 5, and 1 mg/mL anti-S. marisflavi AP629 IgY could achieve survival rates of 77.5%, 50%, and 22.5% at day 12 when the infection and injection therapy were carried out at the same time, respectively. However, survival rates of sea cucumbers treated with 25 mg/mL of nonspecific IgY were only 7.5% at day 12. All sea cucumbers in the positive control group died within twelve days after bacterial inoculation. Levels of the five humoral immune factors (LYZ, ACP, NOS, SOD, CAT) released by coelomocytes were significantly increased in the specific IgY group compared to the nonspecific IgY and positive control groups within 12 h. However, the activities of LYZ, ACP, and SOD decreased rapidly at the 48 h time point in the specific IgY group, indicating that specific IgY treatment could shorten the time needed to restore balance in sea cucumber immune systems. Oral prophylaxis with egg yolk powders was that all sea cucumbers were challenged with 4.2 × 106 CFU S. marisflavi AP629 by intraperitoneal injection after 60 days of feeding. Survival rates of diets containing 10%, 5%, and 1% specific egg yolk powder were 57.5%, 52.5%, and 30% by day 12, respectively, and the survival rate was 27.5% for the nonspecific group and 22.5% for the positive control group. After feeding for 60 days, enzyme activities of LZY, NOS, and SOD were all significantly enhanced in sea cucumbers fed with specific egg yolk powder when compared to the control group (p < 0.05). This study demonstrated that the phagocytic activities of coelomocytes were significantly stimulated after specific IgY treatment over that of nonspecific IgY or without IgY treatments in sea cucumbers (p < 0.05). Overall, our results revealed that anti-S. marisflavi AP629 IgY has a positive immunomodulatory effect on sea cucumbers infected with S. marisflavi AP629.

Abstract
Red-spotted grouper nervous necrosis virus (RGNNV) is one of the most important viruses which mainly infects the larva of marine and freshwater fish with high mortality and affects the fishery industry worldwide. Currently, there are no effective vaccines available for the fish larva infected with NNV. Immunoglobulin yolk (IgY) origin of oviparous animals is passed from the blood serum and concentrated in the egg yolk. With the advantages of high yield, cost-effectiveness, and high stability, IgY can be widely used in passive immunization, especially in young animals in which adaptive immunity is not fully developed. In this study, we have cloned and expressed the recombinant capsid protein of RGNNV in Escherichia coli and used as an immunogen for generating specific anti-RGNNV IgY antibody in laying hens. Water-soluble fractions (WSF) of the specific IgY were isolated from egg yolk and purified by two-step precipitation with saturated ammonium sulfate salting. By Enzyme linked immunosorbent assay (ELISA), the titer of the IgY reached a peak at the 6th week post of immunization and had a strong stability at a wide range of temperature, pH, and pepsin enzyme digestion. The purified IgY was competent to neutralize and completely inhibited the RGNNV replication in the grouper fin cell line (GF-1), indicating that it was highly specific and effectively recognized RGNNV. The results will pave a new way for the prevention of RGNNV infection.

Abstract
The emergence of multi antibiotic resistance by the pathogens and toxic impacts on host metabolism has opened new perspectives to rational novel vaccine techniques. Outbreaks of Aeromonas hydrophila in aquaculture caused high mortality throughout the world and resulted in the extensive economic loss in the aquaculture industry. In this study, we report the efficacy of anti-A. hydrophila IgY antibodies by passive vaccination and its prophylactic or therapeutic effects against A. hydrophila in blunt snout bream. Inactivated A. hydrophila immunized hens produced effective IgY antibodies that were stable at temperatures less than 60 °C or the pH value was >4. The specific IgY can be bound directly to A. hydrophila that efficiently agglutinated and inhibited the bacterial growth in a dose-dependent manner. The specific IgY had significantly enhanced the phagocytosis activity of macrophages and resulted in rapid bacterial clearance. Anti-A. hydrophila IgY antibodies significantly increased macrophage mediated respiratory burst, including nitric oxide and superoxide anion production and subsequently killed the pathogen. Histopathological studies of intestine and spleen from vaccinated blunt-snout bream challenged with A. hydrophila showed the structural integrity of the organs was maintained intact from the bacterial injury. In addition, the prophylactic and therapeutic immunization, protected the blunt snout bream and the survival is approximately about 60% and 50%, respectively. These data suggest that specific IgY has the potential for protecting blunt snout bream against A. hydrophila infection and show promise for the future development of harmless vaccines.

Abstract
Vibrio anguillarum is one of the most harmful pathogens associated with hemorrhage septicemia syndrome in the half-smooth tongue sole (C. semilaevis) due to its high virulence. In this study, we attempted to treat half-smooth tongue sole with anti-V. anguillarum egg yolk powder to elicit a passive immunity directly against V. anguillarum infection. Anti-V. anguillarum IgY was β-cyclodextrin encapsulated in egg yolk powders as feed, which could avoid antibody inactivation in the gastrointestinal tract of half-smooth tongue sole. The IgY had an inhibiting effect on the infection of V. anguillarum in vitro. The survival rate of half-smooth tongue sole fed with basal diet containing 15% anti-V. anguillarum egg yolk powder was 70% after 7 days post-V. anguillarum challenge (10(7) CFU), which was significantly higher than those fed without anti-V. anguillarum egg yolk powder. As well, the bacterial burden in blood, liver, spleen and kidney was significantly lower in half-smooth tongue sole fed with specific IgY than those fed with non-specific IgY. These results suggested that pathogen-specific IgY may provide a valuable treatment for vibriosis infection and can be a promising food additive.

Abstract
This paper investigates the efficacy of Gracilaria corticata, Saccharomyces cerevisiae and gamma irradiation WSSV as immunostimulants to white shrimp Litopenaeus vannamei. Seven hundred and twenty healthy shrimp SPF L. vannamei subadult with average weight of 10 ± 1.02 g were collected and divided into 8 groups. The first group (T1) was fed with commercial pellet, the second group (T2) fed with S. cerevisiae (2 g/kg), the third group (T3) fed with G. corticata powder mixed with shrimp feed (2 g/kg) and, finally, the fourth group (T4) was fed with commercial pellet and injected intramuscularly gamma irradiant WSSV (1 μl/gbw) for 10 days. The shrimps were then injected with WSSV and maintained for 25 days. The positive control group for each treatment was maintained in the same manner but without injection with WSSV. Moreover, survival rate and immune parameters such as total hemocyte count (THC), total protein plasma (TPP), superoxide dismutase (SOD) activity, peroxidase (POD) activity and phenoloxidase activity (PO) were determined. Results indicated that the survival rates for groups T4, T3 T2 and T1 were 57.05 ± 3.52%, 22.5 ± 0.5%, 15 ± 1.05% and 00.0 ± 0%, respectively. Ultimately, at the end of the study the shrimp group T4 showed higher hematological data: THC, TPP, SOD, POD and PO. The study concluded that gamma irradiant WSSV is effective immunostimulants in shrimp L. vannamei and the immunity has better performances than those of the G. corticata and S. cerevisiae.

Abstract
Vibrio spp. are major causes of mortality in white shrimp (Litopenaeus vannamei) which is lacking adaptive immunity. Passive immunization with a specific egg yolk antibody (IgY) is a potential method for the protection of shrimp against vibriosis. In this study, immune effects of the specific egg yolk powders (IgY) against both V. harveyi and V. parahaemolyticus on white shrimp were evaluated. The egg yolk powders against V. harveyi and V. parahaemolyticus for passive immunization of white shrimp were prepared, while a tube agglutination assay and an indirect enzyme-linked immunosorbent assay (ELISA) were used for detection of IgY titer. Anti-Vibrio egg yolk was encapsulated by β-cyclodextrin, which could keep the activity of the antibody in the gastrointestinal tract of shrimp. The results showed that the anti-Vibrio egg powders had an inhibiting effect on V. harveyi and V. parahaemolyticus in vitro. Lower mortality of infected zoeae, mysis, and postlarva was observed in groups fed with anti-Vibrio egg powders, compared with those fed with normal egg powders. The bacterial load in postlarva fed with specific egg powders in seeding ponds was significantly lower than those fed with normal egg powders in seeding ponds. These results show that passive immunization by oral administration with specific egg yolk powders (IgY) may provide a valuable protection of vibrio infections in white shrimp.

Abstract
Vibrio splendidus is one of the most harmful pathogens associated with skin ulceration syndrome in the sea cucumber (Apostichopus japonicus) due to its high virulence and frequency of appearance. The objective of this study was to determine the effectiveness of chicken egg yolk antibody (IgY) against V. splendidus infection in the sea cucumber. Whole V. splendidus cells were used as an immunogen to immunize 20 White Leghorn hens (25 weeks old). IgY was produced from egg yolks obtained from these immunized hens using water dilution, two-step salt precipitation and ultrafiltration. The purity of the IgY produced was approximately 83%. Enzyme-linked Immunosorbent Assay indicated a high specificity for IgY with a maximum antibody titer of 320,000. The growth of V. splendidus in liquid medium was significantly inhibited by IgY in a dose-dependent manner at concentrations ranging from 1 to 10 mg/mL. The protective effects of IgY were evaluated in sea cucumber by intraperitoneally injecting anti-V. splendidus IgY antibodies (10 mg/mL) or immersing the sea cucumber in aqueous IgY (1 g/L) after an intraperitoneal injection of V. splendidus. Intraperitoneal injection resulted in an 80% survival while immersion resulted in a 75% survival during the 11-day experimental period. The survival rates were significantly higher than the positive control and the non-specific IgY group (P < 0.05). As well, the bacterial burden in the respiratory tree, intestine and coelomic liquid was significantly (P < 0.05) lower in sea cucumber treated with specific IgY than those treated with non-specific IgY. The phagocytosis of coelomocytes for V. splendidus in the presence of specific IgY was significantly (P < 0.05) higher than that obtained with non-specific IgY or without IgY, suggesting that specific IgY enhanced phagocytic activity. The current work suggests that specific IgY has potential for protecting sea cucumbers against V. splendidus infection.

Abstract
Oral administration of chicken egg yolk immunoglobulins (IgY) has attracted much attention as a means for controlling infectious diseases caused by microorganisms. This study evaluated the protective effect of IgY against Vibrio anguillarum infection in ayu, Plecoglossus altivelis. IgY was isolated from egg yolks laid by hens initially immunized with formalin-inactivated V. anguillarum. Lower mortality of ayu was observed in groups treated with anti-V. anguillarum IgY (aVIgY), compared with those treated with saline or with nonspecific IgY (nspIgY). All fish in saline-treated groups died within seven days after bacterial inoculation. The bacterial load in blood, liver, and spleen was significantly lower in fish treated with aVIgY than in fish treated with nspIgY. aVIgY treatment significantly reduced tumor necrosis factor-α (PaTNF-α), interleukin-1β (PaIL-1β), transforming growth factor-β (PaTGF-β), and leukocyte cell-derived chemotaxin-2 (PaLECT2) transcript levels in the head kidney, spleen, and liver of ayu challenged by V. anguillarum, compared with nspIgY treatment. The phagocytic activity of macrophages for V. anguillarum in the presence of specific IgY was significantly higher than that seen for nonspecific IgY. These results suggest that passive immunization by oral intubation with pathogen-specific IgY may provide a valuable treatment for V. anguillarum infection in ayu.

Abstract
The generation and use of avian antibodies is of increasing interest in a wide variety of applications within the life sciences. Due to their phylogenetic distance, mechanisms of immune diversification and the way in which they deposit IgY immunoglobulin in the egg yolk, chickens provide a number of advantages compared to mammals as hosts for immunization. These advantages include: the one-step purification of antibodies from egg yolk in large amounts facilitates having a virtually continuous supply; the epitope spectrum of avian antibodies potentially grants access to novel specificities; the broad absence of cross-reactivity with mammalian epitopes avoids assay interference and improves the performance of immunological techniques. The polyclonal nature of IgY antibodies has limited their use since avian hybridoma techniques are not well established. Recombinant IgY, however, can be generated from mammalian monoclonal antibodies which makes it possible to further exploit the advantageous properties of the IgY scaffold. Moreover, cloning and selecting the immune repertoire from avian organisms is highly efficient, yielding antigen-specific antibody fragments. The recombinant approach is well suited to circumvent any limitations of polyclonal antibodies. This review presents comprehensive information on the generation, purification, modification and applications of polyclonal and monoclonal IgY antibodies.

Abstract
The worldwide shrimp culture is beset with diseases mainly caused by white spot syndrome virus (WSSV) and suffered huge economic losses, which bring out an urgent need to develop the novel strategies to better protect shrimps against WSSV. In the present study, CpG-rich plasmid pUC57-CpG, plasmid pUC57 and PBS were employed to pretreat shrimps comparatively to evaluate the protective effects of CpG ODNs on shrimps against WSSV. The survival rates, WSSV copy numbers, and antiviral associated factors (Dicer, Argonaute, STAT and ROS) were detected in Litopenaeus vannamei. There were higher survival proportion, lower WSSV copy numbers, and higher mRNA expression of Dicer and STAT in pUC57-CpG-pretreatment shrimps than those in pUC57- and PBS-pretreatment shrimps after WSSV infection. The Argonaute mRNA expression in pUC57-CpG-, pUC57- and PBS-pretreatment shrimps after WSSV infection was significantly higher than that of shrimps post PBS stimulation on the first day. The ROS levels in pUC57-CpG-pretreatment shrimps post secondary stimulation of PBS were significantly higher than those post WSSV infection on the first day. These results together demonstrated that pUC57-CpG induced partial protective immunity in shrimps against WSSV via intermediation of virus replication indirectly and could be used as a potential candidate in the development of therapeutic agents for disease control of WSSV in L. vannamei.
