Abstract
Galectins are a family of lectins that are widely distributed β-galactoside-binding proteins identified in diverse organisms. Galectin family have appeared as pattern recognition receptors (PRRs) responsible for initiating and controlling the innate immunity. The present study aimed to study the binding ability and potential role in PRRs of galectin-related protein B-like (LhGal B-like) from redlip mullet (Liza haematocheila) involved in the host immune responses. We constructed a cDNA library of redlip mullet and identified the LhGal B-like sequence. By sequence analysis and multiple sequence alignment, we revealed that LhGal B-like contains a conserved carbohydrate recognition domain (CRD) and consists of 135 amino acids with a predicted molecular weight of 16.07 kDa. In addition, pairwise comparison results showed that LhGal B-like shares higher sequence identity (82.2-95.2%) and similarity (89-95.9%) with fish species than those (34.1-37.8% and 57.2-58.1%, respectively) with other species. The phylogenetic tree showed that LhGal B-like clustered into the fish group and was evolutionally related to Mastacembelus armatus. The tissue distribution results revealed that LhGal B-like was expressed ubiquitously in all the tested tissues, where it was highly expressed in the brain, followed by gills and muscle. The immune modulated expression of LhGal B-like was observed by injecting lipopolysaccharide (LPS), polyinosinic:polycytidylic acid (poly I:C) and Lactococcus garvieae (L. garvieae). According to the results, in the gills, the mRNA expression of LhGal B-like was significantly upregulated upon LPS treatment after 48 h and upon poly I:C treatment after 48 and 72 h. In addition, the result showed significant upregulations upon LPS and poly I:C treatment after 24 h. However, significant downregulation was also shown in the earlier phase after injection of poly I:C and L. garvieae in gills. Further, the binding affinity of recombinant LhGal B-like (rLhGal B-like) was evaluated using carbohydrate, pathogen-associated molecular patterns (PAMP) and bacterial binding assays. The rLhGal B-like could bind all the examined carbohydrates but had a higher affinity to α-lactose. PAMPs and bacterial binding experiments verified a wide range of PAMP molecules and bacterial strains that rLhGal B-like could bind to. Moreover, we examined the agglutination activity of rLhGal B-like, and the result showed that it could aggregate all the gram-positive and gram-negative bacteria. Taken together, our findings reveal the functional aspects of LhGal B-like as a PRR and the potential involvement of LhGal B-like in the innate immunity of redlip mullet.

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.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 128:104333. [PMID: 34914929 DOI: 10.1016/j.dci.2021.104333] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 09/28/2021] [Accepted: 12/07/2021] [Indexed: 06/14/2023]
Abstract
Galectins belong to the β-galactoside binding protein family, which have conserved carbohydrate-recognition domains (CRDs) and participate in innate and acquired immunity in animals. In this study, two galectin genes were cloned from Onychostoma macrolepis, OmGal-3 (galectin-3) and OmGal-9 (galectin-9). The open reading frames (ORFs) of OmGal-3 and OmGal-9 contain 732 and 978 base pairs, encoding 243 and 325 amino acids, respectively. OmGal-3 contains a C-terminal CRD, but OmGal-9 contains an N-terminal CRD and a C-terminal CRD. Two galectins were expressed at varying levels in all tissues examined, with the liver showing the highest expression. The relative gene expression levels of OmGal-3 and OmGal-9 following Aeromonas hydrophila infection were significantly up-regulated in the liver and spleen, and OmGal-9 had a greater increase than OmGal-3. The recombinant OmGal-3 and OmGal-9 proteins (rOmGal-3 and rOmGal-9) were authenticated and verified by SDS-PAGE and western blotting. ROmGal-3 and rOmGal-9 agglutinated all tested bacteria, including 3 g-positive bacteria (Aeromonas hydrophila, Escherichia coli, and Vibrio parahaemolyticus) and 3 g-negative bacteria (Streptococcus agalactiae, Staphylococcus aureus, and Bacillus cereus) in vivo without Ca2+. ROmGal-3 showed strong binding both to gram-positive and gram-negative bacteria and OmGal-9 had a stronger binding activity against gram-positive bacteria. Furthermore, rOmGal-3 and rOmGal-9 exhibited dose-dependent binding capability to two classic pathogens associated molecular pattern (LPS and PGN) and two sugars (d-lactose and d-galactose), and rOmGal-3 has better binding activity at lower concentrations in LPS and PGN than rOmGal-3. The integrated analyses indicate that the two galectins probably play an important role in innate immune defense by binding to bacterial cells via the CRD domain against pathogen infection.
