Abstract
Lectins are a unique group of nonimmune carbohydrate-binding proteins or glycoproteins that exhibit specific and reversible carbohydrate-binding activity in a non-catalytic manner. Lectins have diverse sources and are classified according to their origins, such as plant lectins, animal lectins, and fish lectins. Marine organisms including fish, crustaceans, and mollusks produce a myriad of lectins, including rhamnose binding lectins (RBL), fucose-binding lectins (FTL), mannose-binding lectin, galectins, galactose binding lectins, and C-type lectins. The widely used method of extracting lectins from marine samples is a simple two-step process employing a polar salt solution and purification by column chromatography. Lectins exert several immunomodulatory functions, including pathogen recognition, inflammatory reactions, participating in various hemocyte functions (e.g., agglutination), phagocytic reactions, among others. Lectins can also control cell proliferation, protein folding, RNA splicing, and trafficking of molecules. Due to their reported biological and pharmaceutical activities, lectins have attracted the attention of scientists and industries (i.e., food, biomedical, and pharmaceutical industries). Therefore, this review aims to update current information on lectins from marine organisms, their characterization, extraction, and biofunctionalities.

Seasonal Changes of Growth, Immune Parameters and Liver Function in Wild Chinese Sturgeons Under Indoor Conditions: Implication for Artificial Rearing. Front Physiol 2022; 13:894729. [PMID: 35514333 PMCID: PMC9062076 DOI: 10.3389/fphys.2022.894729] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Accepted: 04/01/2022] [Indexed: 01/08/2023] Open
Abstract
Seasonality has a significant effect on the physiology of fish, especially the effect of water temperature changes. In the present study, the growth, innate immune parameters and liver function indices of two rescued wild adult Chinese sturgeons under captive conditions were monitored for 1 year. The results showed that the total annual weight loss rate of the male was −4.58% and the total weight gain rate of the female was 24.12%, in which the weight of both individuals registered highly significant differences in summer, fall and winter (p < 0.01). The male Chinese sturgeon also exhibited negative specific growth rates (−0.1 to −0.8%) during spring to fall, whereas positive specific growth rates, ranging from 0.03 to 0.11%, were recorded in the female. Seasonality also affected the innate immune parameters of the two Chinese sturgeons, in which leukocytes had been increasing since spring and C-reactive protein (CRP) content was significantly higher (p < 0.05) in summer than fall in both individuals. The CRP level of the male Chinese sturgeon showed a significant increase from fall to winter (p < 0.05), suggesting that it may have contracted infection or inflammation during this study period. With the analysis of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), transaminase (AST:ALT) ratio, alkaline phosphatase, albumin to globulin ratio and triglycerides, it was found that the liver function of the captive Chinese sturgeons was adversely affected along seasonal changes, with the highest degree of liver impairment in winter. In combining observations from growth performance and changes in innate immune and liver function parameters, the present findings deduced that the male Chinese sturgeon under study was more susceptible to seasonal changes than the female. For better indoor culture of adult Chinese sturgeons, monitoring of hematological parameters to detect early signs of inflammation and liver function abnormality should be conducted with routine veterinary care during prolonged captivity.

Abstract
Animal C-reactive protein (CRP) has a widespread existence throughout phylogeny implying that these proteins have essential functions mandatory to be preserved. About 500 million years of evolution teach us that there is a continuous interplay between emerging antigens and components of innate immunity. The most archaic physiological roles of CRP seem to be detoxication of heavy metals and other chemicals followed or accompanied by an acute phase response and host defense against bacterial, viral as well as parasitic infection. On the other hand, unusual antigens have emerged questioning the black-and-white perception of CRP as being invariably beneficial. Such antigens came along either as autoantigens like excessive tissue-stranded modified lipoprotein due to misdirected food intake linking CRP with atherosclerosis with an as yet open net effect, or as foreign antigens like SARS-CoV-2 inducing an uncontrolled CRP-mediated autoimmune response. The latter two examples impressingly demonstrate that a component of ancient immunity like CRP should not be considered under identical “beneficial” auspices throughout phylogeny but might effect quite the reverse as well.

Abstract
Tilapias are cultured globally and are rising in acceptance as the most important freshwater aquaculture species. Monitoring of serum biomarkers is a promising tool in aquaculture to screen the health status as they are virtuous indicators of extreme stress and organ dysfunction in fish. The present study examined the serum biomarkers of oxytetracycline (OTC)-dosed Nile tilapia Oreochromis niloticus at 0, 80 and 800 mg/kg biomass/day, i.e., 0X, 1X, and 10X the approved dose (X = 80 mg OTC/kg biomass/day) for 10 consecutive days. The fish biomass and levels of serum glucose, aspartate aminotransferase, alanine aminotransferase, creatinine and C-reactive protein (CRP) were determined at scheduled intervals. A significant dose-dependent reduction in fish biomass during the OTC-dosing (5.84%) and post-OTC dosing (8.16%) periods was observed. All the serum biomarkers of Nile tilapia increased significantly on day 10 OTC-dosing. Though their levels reduced significantly, normalcy was not achieved even after 42 days of cessation of OTC-dosing, except CRP. The CRP reached the normal level on day 25 post-OTC dosing in the 1X group. The results, thus, demonstrated that the oral OTC-dosing influences the physiological state of apparently healthy Nile tilapia in a dose-dependent manner. These changes were, however, reversible upon discontinuation of OTC-dosing. The set of data observed on growth reduction and elevated serum biomarker levels even after 42 days of cessation of OTC-dosing, thus, raises questions on the utility of oral OTC-dosing.

Abstract
Gabapentin (GPT) has become an emerging contaminant in aquatic environments due to its wide application in medical treatment all over the world. In this study, embryos of zebrafish were exposed to gabapentin at realistically environmental concentrations, 0.1 μg/L and 10 μg/L, so as to evaluate the ecotoxicity of this emergent contaminant. The transcriptomics profiling of deep sequencing was employed to illustrate the mechanisms. The zebrafish (Danio rerio) embryo were exposed to GPT from 12 hpf to 96 hpf resulting in 136 and 750 genes differentially expressed, respectively. The results of gene ontology (GO) analysis and the Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis illustrated that a large amount of differentially expressed genes (DEGs) were involved in the antioxidant system, the immune system and the nervous system. RT-qPCR was applied to validate the results of RNA-seq, which provided direct evidence that the selected genes involved in those systems mentioned above were all down-regulated. Acetylcholinesterase (AChE), lysozyme (LZM) and the content of C-reactive protein (CRP) were decreased at the end of exposure, which is consistent with the transcriptomics results. The overall results of this study demonstrate that GPT simultaneously affects various vital functionalities of zebrafish at early developmental stage, even at environmentally relevant concentrations.

Abstract
C-reactive protein (CRP) is an evolutionarily conserved protein. From arthropods to humans, CRP has been found in every organism where the presence of CRP has been sought. Human CRP is a pentamer made up of five identical subunits which binds to phosphocholine (PCh) in a Ca2+-dependent manner. In various species, we define a protein as CRP if it has any two of the following three characteristics: First, it is a cyclic oligomer of almost identical subunits of molecular weight 20–30 kDa. Second, it binds to PCh in a Ca2+-dependent manner. Third, it exhibits immunological cross-reactivity with human CRP. In the arthropod horseshoe crab, CRP is a constitutively expressed protein, while in humans, CRP is an acute phase plasma protein and a component of the acute phase response. As the nature of CRP gene expression evolved from a constitutively expressed protein in arthropods to an acute phase protein in humans, the definition of CRP became distinctive. In humans, CRP can be distinguished from other homologous proteins such as serum amyloid P, but this is not the case for most other vertebrates and invertebrates. Literature indicates that the binding ability of CRP to PCh is less relevant than its binding to other ligands. Human CRP displays structure-based ligand-binding specificities, but it is not known if that is true for invertebrate CRP. During evolution, changes in the intrachain disulfide and interchain disulfide bonds and changes in the glycosylation status of CRP may be responsible for different structure-function relationships of CRP in various species. More studies of invertebrate CRP are needed to understand the reasons behind such evolution of CRP. Also, CRP evolved as a component of and along with the development of the immune system. It is important to understand the biology of ancient CRP molecules because the knowledge could be useful for immunodeficient individuals.

Abstract
The expression of genes encoding the acute phase proteins (APP) during the course of Trypanasoma carassii infection in the goldfish was determined using quantitative PCR. Significant changes in the mRNA levels of ceruloplasmin (Cp), C-reactive protein (CRP), transferrin (Tf), hemopexin (Hx) and serum amyloid A (SAA) were observed in the kidney, liver and spleen at various days post infection (dpi). Of the five acute phase protein genes examined, CRP and SAA exhibited the highest expression in the tissues during the acute infection. Cp and Tf were up-regulated throughout the acute course of infection in the liver. During the chronic phase of the infection, APP expression in the liver was similar to that in the non-infected control fish. At 7 dpi, Cp, Tf and Hx were down-regulated in the spleen, and Cp and Tf kidney, but their mRNA levels gradually returned to those of control non-infected fish. In contrast, during the chronic phase of the infection, there was an up-regulation of Cp, Hx and Tf in the spleen, and Tf and SAA in the kidney. The goldfish CRP was cloned and functionally characterized. CRP was differentially expressed in normal goldfish immune cells, with highest expression in monocytes and lowest expression in mature macrophages. A recombinant goldfish CRP (rgfCRP) was generated using prokaryotic expression. rgfCRP enhanced complement-mediated killing of trypanosomes in vitro, and the lysis increased after addition of immune serum. rgfCRP did not affect the production of reactive oxygen and nitrogen intermediates by monocytes and macrophages, respectively.

Abstract
Intra-muscular injection of turpentine oil was used to induce acute phase response (APR) in Atlantic cod (Gadus morhua L.). The effects on the serum cortisol, total protein, IgM and pentraxin concentration were examined as well as the effects on natural antibody, anti-trypsin and leukocyte respiratory burst activity. The turpentine injection resulted in a 26 fold increase in the cortisol level after 72 h. Slightly reduced serum protein level in both groups was attributed to the restricted feeding during the experimental period. The IgM serum concentration was significantly reduced after 168 h in the turpentine treated fish while the natural antibody activity was not affected. The anti-trypsin activity was initially suppressed but recovered to normal levels at the end of the experiment. The turpentine injection had little effect on the serum level of the pentraxins, CRP-PI and CRP-PII. The respiratory burst activity was significantly suppressed after 72 h. It is concluded that 1) cod shows a relatively slow humoral and cellular response to APR induction, 2) the increase in serum cortisol level may be the key modulator of the mainly suppressive effects on the immune parameters and 3) pentraxins are not typical acute phase proteins in cod.

Abstract
Human C-reactive protein (CRP), as a mediator of innate immunity, removed damaged cells by activating the classical complement pathway. Previous studies have successfully demonstrated that CRPs are differentially induced as glycosylated molecular variants in certain pathological conditions. Affinity-purified CRPs from two most prevalent diseases in India viz. tuberculosis (TB) and visceral leishmaniasis (VL) have differential glycosylation in their sugar composition and linkages. As anemia is a common manifestation in TB and VL, we assessed the contributory role of glycosylated CRPs to influence hemolysis via CRP-complement-pathway as compared to healthy control subjects. Accordingly, the specific binding of glycosylated CRPs with erythrocytes was established by flow-cytometry and ELISA. Significantly, deglycosylated CRPs showed a 7-8-fold reduced binding with erythrocytes confirming the role of glycosylated moieties. Scatchard analysis revealed striking differences in the apparent binding constants (10(4)-10(5) M(-1)) and number of binding sites (10(6)-10(7)sites/erythrocyte) for CRP on patients' erythrocytes as compared to normal. Western blotting along with immunoprecipitation analysis revealed the presence of distinct molecular determinants on TB and VL erythrocytes specific to disease-associated CRP. Increased fragility, hydrophobicity and decreased rigidity of diseased-erythrocytes upon binding with glycosylated CRP suggested membrane damage. Finally, the erythrocyte-CRP binding was shown to activate the CRP-complement-cascade causing hemolysis, even at physiological concentration of CRP (10 microg/ml). Thus, it may be postulated that CRP have a protective role towards the clearance of damaged-erythrocytes in these two diseases.

Abstract
This study measures a whole series of biological endpoints, and histopathological and behavioral changes of carp (Cyprinus carpio L.) fingerlings in order to investigate the adverse effects of a sublethal concentration of 10 microg/L cyfluthrin for 48h and one week using the semi-static test system. The most significantly altered findings of this study was that total antioxidant status levels decreased in 48h, chloride levels decreased in one week, and sodium and phosphorous levels increased in the 48h-exposed group. Plasma cortisol increased in both the 48h-exposed and the one-week-exposed groups. The unique tissue was the brain that had an increased level of malondialdehyde after one week of exposure. Such biomarkers may be used in assessing adverse/toxic effects of pesticides as environmental stressors. Potential oxidative-stress-inducing effect of synthetic pyrethroid cyfluthrin, as lipid peroxidation, in addition to its sodium channel blocking, is reported for the first time as an additional mechanism of action.

Abstract
The potential of C-reactive protein (CRP)-like proteins to be used as a biomarker of health status in cultured carp obtained from various European fish lines has been assessed. Varying CRP-like protein levels in the serum of carp were monitored using an indirect competitive enzyme-linked immunosorbent assay. CRP-like protein basal levels in normal fish varied between carp lines, ranging on average from 2.9+/-0.15 to 12.57+/-1.19 microg ml(-1). Serum levels of CRP-like protein in carp were observed to increase several fold in fish infected with the pathogen Aeromonas hydrophila. However, carp injected with Escherichia coli lipopolysaccharide (LPS) serotype 0111:B4 did not exhibit an increase in CRP-like proteins levels.

Abstract
The decline in the fisheries of traditional marine species has been an incentive for the diversification of today's aquaculture sector into the intensive rearing of many finfish species. The increasing interest in commercial farming of different finfish species is expected to result in similar environmental and husbandry-related problems as have been experienced in the development of the salmonid farming industry. An understanding of the biology of the fish species being cultured, in particular the immune response is important for improved husbandry and health management of the species. The innate immune system of fish has generated increasing interest in recent years and is now thought to be of key importance in primary defence and in driving adaptive immunity. This review focuses on key components (cellular and humoral) of the innate immune responses of different fish species of commercial importance.

Abstract
Lectins are primordial molecules with multiple known functions. They have been known to exist in fish and other animals for decades and were initially identified as (hem)agglutinins. Demonstration of the importance of vertebrate lectins in innate immunity is a recent effort and is still largely unrealised for fish. This mini-review will tabulate those fish lectins identified since the last major review. In addition, particular lectins for which either functional relevance or functional or structural heterogeneity has been demonstrated are discussed in greater detail.

Abstract
Exposure to dioxins, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) has been related to alterations in cellular and humoral immune responses in both adaptive and innate immune systems of most animal species. These compounds share a common signaling mechanism to exert their effects on cells of the immune system, which includes the aryl-hydrocarbon receptor (AhR) and the AhR nuclear translocator (ARN). Recently, the interference of AhR-ARNT with the nuclear factor (NF)-kappaB signaling pathway has been proposed as a critical event in the adverse effects on the immune system. Studies on the effects of these AhR-ARNT-related toxicants on the immune system of higher and lower phylum animals and knowledge of intracellular mechanisms of toxicity may contribute to development of biomarkers of ecotoxicant exposure and effects. Biomarkers of this kind allow sampling over extended geographic areas, in several sentinel species, including wildlife animals, and facilitate the building of risk models and risk maps of environmentally induced diseases. On the basis of location, biomarker sampled data obtained through evaluation of ecotoxicant exposure and effects on the immune system in sentinel species can be further integrated and analyzed together with other sources of environmental geographic information, or human population health data, by means of geographic information systems (GIS). The spatial analysis capability of GIS can help to evaluate the complex relationships of overlaid information and to identify areas with high risk indices or "hot spots." This integrative approach can be useful in studies contributing to support environmental and health-related policies and regulations.

Abstract
Phosphorylcholine (PC) is a classical ligand of C-reactive protein (CRP), a clinically important acute phase protein. In search of new ligands, CRPs were affinity-purified from several pathological samples, which exhibited distinct molecular variants induced in different diseases. Both glycosylated and non-glycosylated CRPs showed calcium-independent differential-binding to Staphylococcus aureus cell-surface Protein A. CRP possesses separate binding sites for Protein A and PC with different binding constants. We have demonstrated that Protein A is another ligand in addition to PC establishing an extended definition of CRP. Protein A binding may impart immunomodulatory roles of CRP in combating microorganisms or other foreign materials.

Abstract
Changes of serum C-reactive protein (CRP) levels in rainbow trout (Oncorhynchus mykiss) were studied after exposure to formalin, metriphonate or potassium permanganate, which are used in aquaculture as anti-ectoparasitic chemicals. The CRP level in normal trout sera is 88+/-5 microg ml(-1) according to sandwich enzyme-linked immunosorbent assay. CRP levels increased to a maximum at six or nine days after exposure to formalin for 3.5 h at 300 ppm or 9.5 h at 30 ppm, respectively; these levels are 4.3 and 18 times higher than normal. At 18 days after treatment, the CRP level had decreased to significantly below the normal level. After exposure to metriphonate (0.4 ppm for 30 min), the CRP level increased significantly to a maximum at three days after exposure (9.9 times higher than normal), then decreased to below normal. With exposure to potassium permanganate at 40 ppm for 45 min, fish showed significantly lower CRP levels than the normal level at 14 days after exposure. Fish reared at a water temperature of 16.5-19.5 degrees C showed significantly higher CRP levels than those reared at 13 degrees C. Measurement of CRP levels in trout serum can be used as a bioindicator of the health condition of the fish.

Abstract
As an acute-phase protein, human C-reactive protein (CRP) is clinically important. CRPs were purified from several samples in six different pathological conditions, where their levels ranged from 22 to 342 microg/ml. Small, but significant, variations in electrophoretic mobilities on native PAGE suggested differences in molecular mass, charge and/or shape. Following separation by SDS/PAGE, they showed single subunits with some differences in their molecular masses ranging between 27 and 30.5 kDa, but for a particular disease, the mobility was the same for CRPs purified from multiple individuals or pooled sera. Isoelectric focusing (IEF) also indicated that the purified CRPs differed from each other. Glycosylation was demonstrated in these purified CRPs by Digoxigenin kits, neuraminidase treatment and binding with lectins. The presence of N-linked sugar moiety was confirmed by N-glycosidase F digestion. The presence of sialic acid, glucose, galactose and mannose has been demonstrated by gas liquid chromatography, mass spectroscopic and fluorimetric analysis. Matrix-assisted laser-desorption ionization analysis of the tryptic digests of three CRPs showed systematic absence of two peptide fragments, one at the N-terminus and the other near the C-terminus. Model-building suggested that the loss of these fragments exposed two potential glycosylation sites on a cleft floor keeping the protein-protein interactions in pentraxins and calcium-dependent phosphorylcholine-binding qualitatively unaffected. Thus we have convincingly demonstrated that human CRP is glycosylated in some pathological conditions.

Abstract
Elevated level of pollutant specific glycosylated molecular variants of C-reactive protein have been purified to electrophoretic homogeneity from the sera of major carp, Catla catla confined in freshwater (CRP(N)) and water polluted with nonlethal doses of cadmium (CRP(Cd)), mercury (CRP(Hg)), phenol (CRP(Ph)) and hexachlorocyclohexane (CRP(Hex)). These CRPs differ amongst themselves in electrophoretic mobility, and in their carbohydrate content ranging from 20-50%. CRPs interact with pneumococcal C-polysaccharide (CPS) showing different binding constants. Both phosphorylcholine (PC) and calcium are indispensable for binding. Studies on amino acid compositions, electrophoretic analysis, isoelectric focusing, binding to PC & CPS and secondary structures of the purified CRPs indicate, that, they differ from each other. However, they share the common properties of a CRP, including pentraxin structure revealed by electron microscopy. Taken together, our results provide a new structural insight regarding the connection between the presence of unique molecular variants and probably the toxicity therein combated.
