Purification and partial characterization of a lectin protein complex, the clathrilectin, from the calcareous sponge Clathrina clathrus. Comp Biochem Physiol B Biochem Mol Biol 2016; 200:17-27.

Abstract
Carbohydrate-binding proteins were purified from the marine calcareous sponge Clathrina clathrus via affinity chromatography on lactose and N-acetyl glucosamine-agarose resins. Proteomic analysis of acrylamide gel separated protein subunits obtained in reducing conditions pointed out several candidates for lectins. Based on amino-acid sequence similarity, two peptides displayed homology with the jack bean lectin Concanavalin A, including a conserved domain shared by proteins in the L-type lectin superfamily. An N-acetyl glucosamine - binding protein complex, named clathrilectin, was further purified via gel filtration chromatography, bioguided with a diagnostic rabbit erythrocyte haemagglutination assay, and its activity was found to be calcium dependent. Clathrilectin, a protein complex of 3200kDa estimated by gel filtration, is composed of monomers with apparent molecular masses of 208 and 180kDa estimated on 10% SDS-PAGE. Nine internal peptides were identified using proteomic analyses, and compared to protein libraries from the demosponge Amphimedon queenslandica and a calcareous sponge Sycon sp. from the Adriatic Sea. The clathrilectin is the first lectin isolated from a calcareous sponge and displays homologies with predicted sponge proteins potentially involved in cell aggregation and interaction with bacteria.

Abstract
An overview on the diversity of 39 lectins from the phylum Porifera is presented, including 38 lectins, which were identified from the class of demosponges, and one lectin from the class of hexactinellida. Their purification from crude extracts was mainly performed by using affinity chromatography and gel filtration techniques. Other protocols were also developed in order to collect and study sponge lectins, including screening of sponge genomes and expression in heterologous bacterial systems. The characterization of the lectins was performed by Edman degradation or mass spectrometry. Regarding their physiological roles, sponge lectins showed to be involved in morphogenesis and cell interaction, biomineralization and spiculogenesis, as well as host defense mechanisms and potentially in the association between the sponge and its microorganisms. In addition, these lectins exhibited a broad range of bioactivities, including modulation of inflammatory response, antimicrobial and cytotoxic activities, as well as anticancer and neuromodulatory activity. In view of their potential pharmacological applications, sponge lectins constitute promising molecules of biotechnological interest.

Abstract
Lectin II from the marine sponge Axinella corrugata (ACL-II) was purified by affinity chromatography on rabbit erythrocytic stroma incorporated into a polyacrylamide gel, followed by gel filtration on Ultrogel AcA 44 column. Purified ACL-II is a lectin with an Mr of 80 kDa and 78 kDa, estimated by SDS-PAGE and by FPLC on Superose 12 HR column, respectively. ACL-II mainly agglutinates native rabbit erythrocytes and this hemagglutinating activity is independent of Ca(2+), Mg(2+) and Mn(2+), but is inhibited by d-galactose, chitin and N-acetyl derivatives, with the exception of GalNAc. ACL-II is stable for up to 65 °C for 30 min, with a better stability at a pH range of 2 to 6. In contrast, ACL-I displays a strong mitogenic and cytotoxic effect.

Abstract
The lectin from the marine sponge Axinella corrugata (ACL-I) was purified by affinity chromatography on rabbit erythrocytic stroma incorporated into a polyacrylamide gel followed by gel filtration on Ultrogel AcA 44 column. Purified ACL-I is a hexameric glycoprotein with a Mr of 82.3 kDa estimated by SDS-PAGE and 78.5 kDa by FPLC on Superose 12 HR column. The pI of lectin is 6.3 and ACL-I is constituted of 13.9 kDa similar subunits some of them linked by disulphide bridges. This lectin agglutinates native rabbit, goat and dog erythrocytes and in less extent human erythrocytes. The hemagglutinating activity is independent of Ca(2+), Mg(2+) and Mn(2+), but it is strongly inhibited by carbohydrates containing N-acetyl groups. ACL-I is stable up to 70 degrees C for 30 min, with optimum pH between 7 and 8, and it is also resistant to enzymatic proteolysis in vitro. In the presence of reducing or denaturant agents, the lectin activity decreases. ACL-I displays chemotactic effect on rat neutrophil in vitro which is inhibited by N-acetyl-d-glucosamine.

Abstract
A GlcNAc-specific lectin was isolated from the sea worm Serpula vermicularis (SVL) (Annelida) and purified by ion-exchange, affinity and gel permeation chromatography. SVL was a homotetrameric protein with native molecular mass of about 50 kDa, and consisted of identical subunits of 12.7 kDa. The carbohydrate content of 1.9% suggested that the lectin was a glycoprotein, and mainly composed by aspartic and glutamic acids, glycine, valine and serine; with relatively lower content of basic amino acids and cysteine. The first 15 residues of the N-terminal region were determined as ADTPCQMLGSRYGWR. It was stable at pH 6-9 and at temperatures up to 40 degrees C. SVL was Ca(2+)-independent lectin that agglutinated native and trypsinized human erythrocytes. Hapten inhibition studies indicated that SVL showed binding specificity only for N-acetyl-d-glucosamine and its derivatives among the monosaccharides tested and required the presence of hydroxyl group at the C-3 of GlcNAc. The presence of hydrophobic p-nitrophenyl aglycone improved inhibitory potency of N-acetyl-d-glucosamine. Ovomucoid and ovalbumin were found to be inhibitors among the glycoproteins used for inhibition assay. The anti-HIV-1 (human immunodeficiency virus) activity of SVL in vitro was determined: SVL inhibited the production of viral p24 antigen and cytopathic effect induced by HIV-1. The EC(50) values were 0.23 and 0.15 microg x mL(-1) respectively.

Abstract
Previously we isolated GlcNAc-specific lectin (DTL) from the ascidian Didemnum ternatanum by affinity chromatography on cross-linked ovalbumin. Here we report the purification and characterization of new D-GlcNAc/D-GalNAc-specific lectin DTL-A from the same ascidian. This lectin was isolated from non-bound cross-linked ovalbumin fraction and further was purified by gel filtration on Sepharose CL-4B, affinity chromatography on GlcNAc-agarose and gel filtration on Superdex 200. SDS-polyacrylamide gel electrophoresis and gel filtration of purified lectin on Sepharose CL-4B indicates that it exists as large aggregates in the native state. Investigations of the carbohydrate specificity of DTL-A by enzyme-linked lectin assay suggest the multi-specificity of this lectin. DTL-A binds BSM, asialo-BSM as well as heparin and dextran sulfate. The binding of DTL-A to BSM was inhibited by monosaccharides D-GlcNAc and D-GalNAc, their alpha- but not beta-anomers. Among polysaccharides and glycoconjugates, DTL-A binding to BSM was effectively inhibited by BSM, asialo-BSM, pronase-treated BSM and synthetic alpha-D-GalNAc-PAA. Fetuin and asialofetuin showed a much lower inhibitory potency, heparin and dextran sulfate were noninhibitory. On the other hand, DTL-A binding to heparin was effectively inhibited by dextran sulfate, fucoidan, whereas BSM showed insignificantly inhibitory effect. DTL-A binding to heparin was not inhibited by D-GlcNAc and D-GalNAc.

Abstract
Toxic water soluble polymeric 3-alkylpyridinium salts (poly APS; MW 18900 and 5520Da) were isolated from the marine sponge Raniera sarai. In vitro they strongly inhibited acetylcholinesterase. In order to evaluate the role of acetylcholinesterase inhibition in toxin lethality, and to assess other possible lethal effects, in vivo experiments were performed on male Wistar rats, and ECG, blood pressure and breathing pattern were monitored. The results showed that none of the animals died due to the acetylcholinesterase inhibitory action of poly-APS. Doses lower than 1mg/kg caused only transient bradycardia and transient prolongation of expirium. At doses above 2.7mg/kg of poly-APS all treated animals died, but signs were not typical of acetylcholinesterase inhibition. Arterial blood pressure fell to mid-circulatory pressure, and breathing stopped after a few breaths with an increase of the residual volume. Autopsy of the experimental animals that died due to the effects of the toxin revealed that mid-size and small sized blood vessels in the heart and lungs were filled with granular brownish material with inclusions of red blood cells and platelets. Data obtained on blood samples from animals treated with poly-APS also revealed numerous thrombocyte aggregates. In vitro poly-APS induced thrombocyte aggregation in a dose dependent manner. The acetylcholinesterase-inhibitory effects were most pronounced only at lower doses of poly-APS. With higher doses those effects were masked or covered by other, more pronounced and faster developing lethal effects of the toxin such as platelet aggregation. Therefore it is reasonable to assume that acetylcholinesterase inhibitory effects are not responsible for the lethal activity of the toxin.

Abstract
Only a few animal phyla have been screened for the presence and distribution of lectins. Probably the most intensively studied group is the mollusk. In this investigation, 22 species from 12 families of tropical sponges collected in Los Roques National Park (Venezuela) were screened for the presence of lectins. Nine saline extracts exhibited strong hemagglutinating activity against pronase-treated hamster red blood cells; five of these reacted against rabbit red blood cells, four with trypsin-treated bovine red blood cells, and five with human red blood cells regardless of the blood group type. Extracts from the three species studied from genus Aplysina (archeri, lawnosa, and cauliformis) were highly reactive and panagglutinating against the panel of red blood cells tested. The lectins from A. archeri and A. lawnosa were purified to homogeneity by ammonium sulfate fractionation, affinity chromatography on p-aminobenzyl-beta-1-thiogalactopyranoside-agarose, and gel filtration chromatography. Both lectins exhibited a native molecular mass of 63 kDa and by SDS-polyacrylamide gel electrophoresis under reducing conditions have an apparent molecular mass of 16 kDa, thus suggesting they occur as homotetramers. The purified lectins contain 3-4 mol of divalent cation per molecule, which are essential for their biological activity. Hapten inhibition of hemagglutination was carried out to define the sugar binding specificity of the purified A. archeri lectin. The results indicate a preference of the lectin for nonreducing beta-linked d-Gal residues being the best inhibitors of red blood cells binding methyl-beta-d-Gal and thiodigalactoside (Gal beta 1-4-thiogalactopyranoside). The behavior of several glycans on immobilized lectin affinity chromatography confirmed and extended the specificity data obtained by hapten inhibition.

Abstract
A natural agglutinin from the serum of the hermit crab Diogenes affinis was purified to homogeneity by a single-step affinity chromatography using N-acetylglucosamine-coupled Sepharose 6B. The purified serum agglutinin (PSA) showed a strong affinity for rat RBC, and its hemagglutinating (HA) activity was specifically dependent on Ca2+ and reversibly sensitive to EDTA. PSA in active form has a molecular mass estimate of 185 kDa and is composed of four non-identical subunits (51, 49, 42 and 39 kDa) cross-linked by interchain disulfide bonds. The homogeneity of PSA was corroborated by immunodiffusion and immunoelectrophoretic analyses using rabbit antiserum raised against the agglutinin. The antibodies in this antiserum appear to be specific for RBC-binding sites of the agglutinin molecules as revealed by the ability of the antiserum to neutralize HA activities of both whole serum and PSA of D. affinis. In HA-inhibition assays performed with several carbohydrates and glycoproteins, PSA showed a distinct and unique specificity for acetyl group in carbohydrates independently of the presence of this group on C-2 or C-5 and its stereochemical arrangement in the axial or equatorial orientation. Besides, this agglutinin appears to recognize the terminal N- and O- acetyl groups in the oligosaccharide chain of glycoconjugates. The HA activity of D. affinis agglutinin was also susceptible to inhibition by lipopolysaccharides from diverse gram-negative bacteria, which might indicate a significant in vivo role of this humoral agglutinin in the host immune response against bacterial infections.

Abstract
The sponge Axinella polypoides contains several D-galactose binding lectins. One of the main components, lectin I was sequenced earlier, the complete sequence of the other major constituent of saline extracts, lectin II has been determined by amino acid sequencing and mass spectrometry. Both lectins have a homology of 65% to each other and both possess a disulfide loop between positions 4 and 46. As long as this loop is closed in both lectins, they can be boiled in the presence of SDS or treated with 6 mol guanidine hydrochloride without losing their hemagglutinating activity. Incubation with beta-mercaptoethanol alone does not effect the carbohydrate binding capacity either. However, reduction of the disulfide bond under chaotropic conditions destroys the activity irreversibly. This disulfide loop is also an immunologically dominant epitope in both lectins, as was revealed with monospecific polyclonal antisera. Thus, sponge lectins seem to be of different origins, since three completely different structures were described: the structure of Geodia cydonium, related to the mammalian S-type lectins with one SH-group, the Axinella lectins with one disulfide loop and the Aaptos lectins I and II with 11 cysteine residues/subunit.

Abstract
We screened the biological activity of 21 marine sponges collected in the northern Adriatic sea. Hemolytic, hemagglutinating, antimicrobial, cytotoxic, and anti-acetilcholinesterase activities of the extracts were monitored. We found that hemolytic activity was generally weak; only extracts from three sponge species possess considerable activity. Hemagglutinating activity was present in almost half of extracts but with little specificity against human erythrocytes of different blood groups. Detectable antimicrobial activity was present in only two extracts, while most of them possessed cytotoxic activity. Strong anti-cholinesterase activity was present only in one sample. 3-alkypyridinium polymers isolated from Reniera sarai were hemolytic and strongly cytotoxic against different cell lines with slightly expressed specificity against transformed cells.

Abstract
Anti-human immunodeficiency virus (HIV)-bioassay-guided fractionation of aqueous extracts of the Caribbean sponge Niphates erecta led to isolation of a novel anti-HIV protein, named niphatevirin. The protein was purified to homogeneity by ethanol precipitation, ammonium sulfate precipitation, gel-permeation chromatography and concanavalin-A-Sepharose affinity chromatography. Niphatevirin potently inhibited the cytopathic effects of HIV-1 infection in cultured human lymphoblastoid (CEM-SS) cells; the effective concentration of drug that results in 50% protection of the cells through inhibition of cell lethality, cell-cell fusion and syncytium formation was approximately 10 nM. Delay of addition of niphatevirin to infected cultures by two hours markedly decreased (approximately 50%) cytoprotection; delay of addition by eight hours resulted in no antiviral activity. Niphatevirin bound to CD4 in a manner that prevented the binding of gp120, but did not directly bind gp120. Niphatevirin (6.5 microM) was inactive in both hemagglutination and hemolysis assays. Niphatevirin had a molecular mass of about 19 kDa by matrix-assisted laser-desorption ionization-time of flight (MALDI-TOF) mass spectrometry, and a native molecular mass of approximately 18 kDa by gel-filtration chromatography. The protein had an acidic isoelectric point of 4.2-4.6, and was shown by periodate acid Schiff's staining to be glycosylated.

Abstract
Giardia lamblia, a cause of diarrheal disease throughout the world, is a protozoan parasite that thrives in the small intestine. It is shown here that wheat germ agglutinin (WGA), a naturally occurring lectin widely consumed in normal human diets, reversibly inhibits the growth of G. lamblia trophozoites in vitro, and reduces infection by G. muris in the adult mouse model of giardiasis. The inhibitory effect was dose related, not associated with cytotoxicity and reversed by N-acetyl-D-glucosamine in accordance with the known specificity of the lectin and in agreement with the presence of GlcNAc residues on the surface membrane of G. lamblia trophozoites. Cell cycle analysis revealed that parasites grown in the presence of WGA are arrested in the G2/M phase, providing an explanation for the lectin-induced inhibition of cell proliferation. Comparison of electrophoretic profiles by lectin blot analysis revealed both glycoprotein induction and suppression in growth-arrested organisms. Our findings raise the possibility that blocking trophozoite growth with naturally occurring dietary lectins may influence the course of giardiasis. In addition, the study of cell cycle arrest by WGA may provide a model to study the regulation of cell division in lower eukaryotes.

Abstract
A protein that showed activity against proteic (casein and hide powder azure) and synthetic (BAEE and HLPA) substrates was isolated from the marine sponge Spheciospongia vesparia. The protease was purified from an aqueous extract by ammonium sulfate precipitation, gel filtration, hydrophobic and HPLC-anion exchange chromatographies. The purified protease showed a single band in SDS-PAGE minigels and had a molecular weight of 29,600, but when submitted to isoelectric focusing it showed 2 bands with isoelectric points of 4.56 and 4.43. Its catalytic action was inhibited by EDTA and 1,10-phenanthroline, so it seemed to be a metalloprotease.

Abstract
A pore-forming protein was detected and purified for the first time from a marine sponge (Tethya lyncurium). The purified protein has a polypeptide molecular mass of 21 kDa and a pI of 6.4. Tethya pore-forming protein (also called Tethya hemolysin) rapidly lysed erythrocytes from a variety of organisms. After binding to target membranes, the hemolysin resisted elution with EDTA, salt or solutions of low ionic strength and hence resembled an integral membrane protein. Erythrocytes could be protected from hemolysis induced by Tethya hemolysin by addition of 30 mM dextran 4 (4-6 kDa; equivalent hydrodynamic diffusion radius, 1.75-2.3 nm) to the extracellular medium, but not by addition of uncharged molecules of smaller size [sucrose, raffinose and poly(ethylene glycol) 1550; equivalent hydrodynamic diffusion radii, 0.46, 0.57 and 1.2 nm, respectively]. This result indicates that hemolysin is able to form stable transmembrane pores with an effective diameter of about 2-3 nm. Treatment of osmotically protected erythrocytes with Tethya hemolysin caused a rapid efflux of intracellular K+ and ATP, and a rapid influx of extracellularly added Ca2+ and sucrose. In negative-staining electron microscopy, target erythrocyte membranes exposed to purified Tethya hemolysin displayed ultrastructural lesions but without visible pores.

Abstract
The sponge Axinella polypoides contains four different D-galactose binding lectins and one, termed lectin IV, which is specific for hexuronic acids. Only the D-galactose binding lectins were investigated in this study. The complete amino-acid sequence of lectin I, the main component in the crude extract was determined. Lectin I is a homodimer and each subunit comprises 144 amino acids with a M(r) of 15,847 +/- 10, as calculated from the sequence data and determined by mass spectrometry. Each subunit contains one intrachain disulfide bridge between positions 4 and 46. Of lectin II, only the first 49 amino acids of the NH2-terminal end were analysed. This part has 29 amino acids in common with lectin I, including a cysteine residue at position 4, also suggesting an intrachain loop in a identical position as in lectin I. The molecular mass of its subunit is 16,235 +/- 10 Da. Only the first 15 NH2-terminal amino acids of lectins III and V could be sequenced. Lectin V was identical to lectin II in all positions, whereas lectin III showed only 5 residues identical to lectins I or II. Thus, lectins I, II and III are derived from three different genes, whereas lectin V may either be a proteolytic cleavage product, or result from different splicing events or may be derived also from a separate gene. Neither of the four lectins showed any similarity to known lectin sequences of animal or plant origin.

Abstract
A new lectin from the sponge Pellina semitubulosa is derived which was extracted and purified to homogeneity. The purified lectin is probably a hexamer of polypeptide chains (each M(r) 34,000) which are covalently linked via disulfide linkages; the isoelectric point is 6.1. The lectin displays the following specificities: D-galactose (50% inhibition of hemagglutination at 0.2 mM) = L-arabinose (0.2 mM) greater than D-fucose (1.5 mM) greater than D-glucose (3.0 mM). It precipitates human erythrocytes (A1, A2, A1B, B, and O) with a titer between 2(8) and 2(11) and erythrocytes from sheep and rabbits with a titer between 2(5) and 2(10). The Pellina lectin displays a strong mitogenic effect on spleen lymphocytes from mice. Immunochemical analyses revealed that both murine T- and B-lymphocytes display a capping of the lectin receptors on their cell surfaces after lectin treatment. Murine macrophages were found to endocytose the lectin. Pellina lectin at concentrations between 0.3 and 10.0 micrograms/ml potently enhances interleukin 1 (IL-1) release from mouse peritoneal macrophages and interleukin 2 (IL-2) production in mixed murine lymphocyte cultures.

Abstract
1. A lectin was isolated from an extract of Branchiostoma lanceolatum by affinity chromatography using an asialo-A-peptone-cellulose column. 2 The lectin is a glycoprotein with a carbohydrate content of 2.7%. The mol. wt is 392,000 +/- 28,000. Two subunits of identical size (183,000 +/- 3000) are linked by non-covalent bonds. 3. The lectin agglutinates a variety of erythrocytes including human A, B, O red blood cells as well as human lymphocytes. 4. Hemagglutination activity is inhibited best by N,N',N"-triacetylchitotriose, followed by N,N'-diacetylchitobiose, which is half as inhibitory. 5. Lectin activity is constant between pH 5 and 10. Divalent cations are not required for binding reactions. Activity is totally destroyed by heating to 60 degrees C for 30 min. 6. The lectin is precipitated from the extract by 30-40% ammonium sulfate saturation.

Abstract
Both the prokaryotic and eukaryotic cells are considered to have arisen from a common progenitor cell. The plasma membrane of the prokaryotic cell became specialized to carry out functions that the eukaryotic cell delegated to cellular organelles. Thus the plasma membrane of the eukaryotic cell remained flexible to evolutionary influences. Thus, provided the structural integrity of the plasma membrane was maintained, alterations within this infrastructure could be tolerated. This gave rise to basic speciation at the cellular level. Such differences in the plasma membrane of these primitive eukaryotic cells were of no importance until the dawn of sexual reproduction, then only like-cells could associate to exchange genetic information. Thus in the protozoa cell-surface, antigens are demonstrable in mating, whereas alloincompatability is intracellular. With the evolution of the Metazoa, in order for like-cells to identify each other, alloincompatability changed from intracellular expression to become expressed on the plasma membrane. Like-cell identification was derived and evolved from the basic feeding mechanism of primitive eukaryotic cells, which involved the induction of lectins that were expressed at the cell-surface. These lectins were induced by the RNA that was complementary to, and complexed with cell surface components of the organisms upon which the eukaryotic cells fed. This RNA was also inserted along with the lectin in the eukaryotic cell plasma membrane, and acted as a template for DNA synthesis. This DNA was then incorporated into the genome of the eukaryotic cell and it became an inheritable characteristic. Thus these lectins could be expressed intracellularly as well as on the plasma membrane. The intracellular expression of these inheritable lectins may have constituted intracellular-alloincompatibility, as well as being used for feeding by agglutination of the organism on the plasma membrane of the eukaryotic cell. With the development of colony formation and the true metazoa, the cell-surface lectins became incorporated into cell-surface components for the identification of like-cells. This represents, in part, the histocompatability antigens of the organisms. At the same time, the lectins were also being increasingly used for the regulation of differentiation, and for what we would classify as immunological reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A new lectin has been isolated from the coral Gerardia savaglia by affinity chromatography, using locust gum as an absorbent, and D-mannose as eluant. Final purification was achieved by Bio-Gel P300 gel filtration. The agglutinin is a protein composed of two polypeptide chains with a Mr of 14800; the two subunits are not linked by disulfide bond(s). The isoelectric point is 4.8, the amino acid composition is rich in the acidic amino acids aspartic acid and glutamic acid. The absorption maximum for the protein was at 276 nm; with a molar absorption coefficient of 1.27 X 10(5) M-1 cm-1. The lectin precipitated erythrocytes from humans (A, B and O), sheep, rabbit and carp with a titer between 2(5) and 10(10); the affinity constant for lectin binding to sheep red blood cells was 2.8 X 10(8) M-1 and the number of binding sites, 3.2 X 10(5)/cell. Ca2+ ions are required for full activity; the pH optimum lies in the range between 6 and 11. Inhibition experiments revealed that the lectin is specific for D-mannose. The lectin is mitogenic only for those spleen lymphocytes from mice which had been activated by lipopolysaccharide. An interesting feature of this lectin is its ability to bind to glycoproteins present in nuclei from CV-1 monkey kidney cells. The fluorescein-isothiocyanate-labelled lectin reacted with six polypeptides in the nuclear envelope from rat liver (Mr 190,000, 115,000, 80,000, 62,000, 56,000 and 42,000) and with two polypeptides in the nuclear matrix or pore complex lamina fraction (Mr 190,000 and 62,000). The lectin inhibited the nuclear envelope mRNA translocation system in vitro. It is suggested that this effect is due to an interaction of the lectin with the nuclear glycoproteins gp190 and/or gp62.

Abstract
The sponge Dysidea herbacea (Keller) was found to possess hemagglutinins. The major component, DHA-I, is a protein with a mol. wt of 26,000, which dissociates into subunits of equal size (14,000). It contains large amounts of glutamic acid and aspartic acid residues, but no half-cystine, methionine or histidine residues. DHA-I reacted with rabbit and human AB0 erythrocytes. D-galactose and lactose were effective inhibitors of DHA-I. The sponge also contained a minor component(s) which reacted preferentially with rabbit erythrocytes but not with human AB0 erythrocytes.

Abstract
Aqueous extracts of 48 sponge species from the Red Sea, the Australian Barrier Reef and the Florida Keys were screened for hemagglutinating, hemolytic, ichthyotoxic and lethal activities. Forty two per cent of the sponge species exhibited agglutinating properties to human erythrocytes of ABO groups. From four species (Haliclona sp., Cinachyra tenuifolia, Callyspongia viridis, Terpios zeteki) the hemagglutinating factors were isolated by gel filtration and affinity chromatography. A molecular weight of 24,000 was determined for the pure hemagglutinin from Haliclona sp. by SDS electrophoresis and of 22,000 for the semipure hemagglutinin from Cinachyra tenuifolia by gel filtration. These hemagglutinins were inhibited by D-lactose, but not by D-melibiose or other oligosaccharides, indicating that they may react with terminal D-galactose beta 1----4 residues. The other semipure hemagglutinins were not inhibited by various sugars tested. Hemolytic activity to human erythrocytes was present in about 15% of the sponge extracts, showing a close relationship to ichthyotoxic activity. More than half of the sponge extracts caused toxic symptoms in mice when injected i.p. Using various concentrations death occurred within 12-48 hr. The lethal factors seem to be related to components of low molecular weight in the sponge extracts.

Abstract
A D-galactose-specific lectin I was extracted from the sponge Geodia cydonium and purified by affinity chromatography. The molecular weight of lectin I as determined by high-pressure liquid gel chromatography, was found to be 36500 +/- 1300. Disc gel electrophoresis in the presence and in the absence of sodium dodecyl sulfate showed that lectin I is a trimer composed of three different subunits (Mr: 13800, 13000 and 12200); two of the three subunits are linked by one disulfide bond. Isoelectric focusing gave a pI of 5.6 for the native molecule and a pI of 4.4 and of 7.4 for the subunits. The three subunits carry carbohydrate side chains, composed of D-galactose (94%) and of arabinose (5%). Based on experiments with lectins, the terminal D-galactose residues are bound by beta 1 leads to 6 and/or beta 1 leads to 4 glycosidic linkages. The Geodia lectin I contains, besides two carbohydrate recognition sites, at least one receptor site for a second lectin I molecule.

Abstract
The distribution of the two D-galactose-specific lectins within the sponge tissue of Axinella polypoides was studied by autoradiography and by an immunohistochemical method on paraplast- and cryosections. Both techniques revealed that the lectins are stored inside the vesicles of the spherulous cells. All spherulous cells, regardless of their appearance in the different types of tissue contained the lectins. Antibodies were purified from an antiserum that reacted with both lectin I and lectin II and from the same antiserum rendered monospecific for lectin I. The purified antibodies were used to demonstrate that lectin II is predominantly present in spherulous cells with small vesicles, and lectin I in those with large vesicles. Electron-microscopic studies revealed that the spherulous cells with small vesicles are derived from archaeocytes and transformed into spherulous cells with large vesicles, a process accompanied by the conversion of lectin II to lectin I. Histological investigations showed that the tips of the bush-like, branched sponge lack the central axis, a spongin fiber network that provides support and stability to the sponge tissue. However, the missing spongin network is already preformed by cell bundles that ultimately produce the numerous fiber strands of the central axis. These bundles are composed exclusively of spindle-shaped cells and the spherulous cells. Other areas where production of spongin fibers is expected are also enriched with spherulous cells. These findings and the reaction of lectin-specific antibodies with the spongin fibers indicate that spherulous cells, and thus the lectins, are involved in synthesis of spongin fiber. Sponges lacking spongin fibers, e.g. Aaptos aaptos and Geodia cydonium, produce lectins with different carbohydrate specificity and possess large numbers of spherulous cells.

Abstract
The agglutination behaviour of four-day-old epimastigote culture forms of 34 Trypanosoma cruzi, and T. cruzi-like stocks from Brazil, Chile, Colombia, Ecuador and Peru were tested with 15 carbohydrate-specific lectins. We distinguished intraspecifically two groups of agglutination reactions: Group 1 includes stocks which react with Triticum vulgaris and Aaptos papillata II (wheat germ agglutinin: WGA-type). Group 2 includes stocks agglutinated by Arachis hypogaea and Aaptos papillata II (peanut lectin: PNA-type). The agglutination reactions with lectins from Triticum vulgaris and Aaptos papillata II correlate with the presence of N-acetylneuraminic acid on the cell surface. After treatment with neuraminidase, the WGA-type is agglutinated by PNA but not by lectins from Triticum vulgaris and Aaptos papillata II. Further results demonstrate that a certain zymodeme pattern can be correlated with carbohydrate determinants.

Abstract
We report the isolation and the purification of an N-acetyl-D-glucosamine specific lectin capable of agglutinating either fixed trypsinized rabbit erythrocytes or chitin particles. An agglutinin assay based on the affinity of this lectin for the chitin was devised with fluorescent particles of scorpion cuticle to measure lectin activity during purification steps. Lectin was isolated from epidermal cell membranes; its molecular weight was determined by gel filtration and polyacrylamide electrophoresis in sodium dodecyl sulfate. Mr was estimated to be 43,000. Lectin could be constituted by two subunits. Mr of which was estimated to be 23,000. The specificity of this lectin against N-acetyl-D-glucosamine and its oligomers suggests a possible role in the dynamics of these saccharides during the cuticle cycle.

Abstract
Epithelial cells may relate to their basement membrane substrates via lectin-like interactions. In a model system for study of this type of interaction, lectin-coated bacteriological plastic petri dishes were presented as substrates for epithelial cell adhesion. Of 21 lectins tested by mixed agglutination against two epithelial cell types, Madin-Darby canine kidney (MDCK), and human embryonic kidney cells (HEK), nine gave less than 5% rosettes and 12 gave 5 to 50% rosettes. Wheat germ agglutinin (WGA) and Geodia cydonium lectin gave the highest percentage of rosettes. Wheat germ agglutinin was readily adsorbed to plastic surfaces and maintained specificity in binding interactions. Both MDCK and HEK cells attached as well to WGA coated petri dishes as to conventional tissue culture dishes. Furthermore, both spread over the lectin-coated surfaces. The MDCK cells grew to confluence and could be subcultured and maintained indefinitely on such surfaces, although WGA in solution was toxic to the cells in concentrations as low as 0.1 to 1.0 microgram/ml. Cell attachment to WGA coated dishes was blocked by cycloheximide only if the cells had been preincubated with the inhibitor for several hours. Cell attachment was not inhibited by pretreatment of cells with neuraminidase. Precoating cells with WGA blocked binding to both WGA-coated surfaces and untreated tissue culture dishes. Cells attached to WGA-coated dishes could not be readily dislodged by trypsin-EDTA for the first 2 h after subculture. By 4 h, attachment was again trypsin sensitive, suggesting that the cells synthesized a trypsin-sensitive material that was laid down between the cell surface and the WGA-coated dish. Regeneration of trypsin sensitivity was not blocked by cycloheximide.

Abstract
The carbohydrate binding specificity of leukoagglutinin (La; Phaseolus vulgaris isolectin L4) was studied by using quantitative precipitation and precipitation-inhibition. A series of purified glycopeptides and synthetic oligosaccharides were used as inhibitors. The minimal structural unit required for La binding was the disaccharide GlcNac(1 leads to beta 2)Man. Additions for this basic unit of different sugar residues gave a positive or negative contribution to binding. The most complementary structure was the pentasaccharide (formula: see text). This pentasaccharide units occurs in tetraantennary N-acetyllactosamine-type glycoprotein glycans. Glycoproteins containing such structures were accordingly precipitated by La. Selected glycopeptides and oligosaccharides were also tested as inhibitors of La-induced DNA synthesis in human lymphocytes. The pattern of inhibition was essentially the same as that obtained by precipitation-inhibition, indicating that binding to lymphocytes via the carbohydrate binding site of the lectin is an essential step in the activation process.

Abstract
Four-day-old promastigote culture forms of L. tropica major from USSR (LV-252, LV-253, LRC L-38) and Saudi Arabia (Kö, Ha), L. tropica minor from USSR (LV-239, LRC L-39) Leishmania sp. from Israel (Ro) and Saudi Arabia (Ve-322, Schwe, Ne), L. donovani from Sudan (3S, 1-S, LV-139) and India (LV-125, LRC L-51), L donovani infantum from Israel (LV-140), and L. aethiopica from Ethiopia (LV-1, LV-16, LV-24, LV-26) were tested using the following lectins: C. ensiformis, R. communis-120, A. polypoides, P. vulgaris, E. europaeus, D. biflorus, L. tetragonolobus, U. europaeus, L. alpinum, A. papillata II, A. hypogaea, and S. hispida. All strains reacted with C. ensiformis, R. communis-120, and A. polypoides. No agglutination reactions were observed with P. vulgaris, D. biflorus, E. europaeus, and L. tetragonolobus. Agglutination differences were detected by reactions with A. papillata II, U. europaeus, L. alpinum, A. hypogaea, and S. hispida. L. tropica minor (LRC L-39, LV-249), L. donovani (LV-239, 1-S, 3S, LRC L-51), L. aethiopica (LV-1, LV-15, LV-24, LV-26), and L. tropica major (LB-242, LV-253, LRC LK-38, Kö, Ha) are distinguishable with lectins. From L. tropica major two intraspecific forms can be identified: USSR-type (LV-252, LV-253, LRC L-38) and a Near East-type (Kö, Ha). The Leishmania sp. strains (Ve-322, Ne, Ro, Schwe) belong to the Near East-type. The strains L. donovano LV-140 and L. donovani LV-125 react as L. tropica minor, a fact which cannot be elucidated. The L. donovani strains from Sudan cannot be distinguished from the Indian strain L. donovani LRC L-51.

Abstract
A definition and classification of lectins (carbohydrate-binding (glyco)proteins) is given on the basis of new data and experimental results. Especially the biological role of bacterial, vertebrate and sponge lectins is discussed. The lectin-toxin combination offers an excellent model not only for studying adhesion to and penetration through the cell membrane, but also for hybridization with antibody fragments showing anti-tumor specificity.

Abstract
From the marine sponge Halichondria panicea a lectin was isolated and characterized. The homogeneous lectin (composed of protein to 80.7% and of neutral carbohydrates to 14.1%) had a molecular weight of 78,000 (determined by gel filtration) and consisted of four subunits with a molecular weight of 21,000 each (determined by gel electrophoresis in the presence of sodium dodecyl sulfate). The hemagglutinating activity was only slightly dependent upon ionic strength and incubation temperature and did not require divalent cations, but it was inhibited by reagents for thiol groups. The Halichondria lectin was completely inhibited in hemagglutination competition experiments in the presence of fetuin, D-galacturonic acid, D-glucuronic acid, polygalacturonic acid, or L-fucose. The purified Halichondria lectin did not cause reaggregation of dissociated H. panicea cells. From the same sponge species bacteria were isolated and identified as Pseudomonas insolita. These bacteria were cultivated in marine broth 2216. Under these culture conditions the bacteria grew only in the presence of the homologous lectin; the lectin-caused effect was not abolished by D-glucuronic acid or D-galacturonic acid. However, after addition of a polysaccharide-containing fraction isolated from P. insolita, the lectin-caused, growth-promoting effect was abolished. Other lectins were found to exhibit no growth-promoting effect. On the basis of colony counts, P. insolita was the predominant bacterial species in the sponge extract; 1.9 X 10(6) Pseudomonas colonies were measured in extracts isolated from 1 g of sponge. The assumption of an interrelationship between the sponge and the bacterium is supported by the results indicating that the Halichondria lectin has no effect on the growth of such bacteria isolated from six other marine sponge species. Evidence is presented which indicates that the Halichondria lectin is not utilized during growth of the Pseudomonas species. Lectin activity was detected on the surface of mucoid cells from H. panicea. From the data obtained the possibility is discussed that the Halichondria lectin is a basis for a symbiotic relationship between the sponge and the bacterium.

Abstract
Trypanosoma cruzi at various stages of maturation and differentiation have been isolated by conventional cellular fractionation procedures and characterized by cell surface markers using 30 highly purified lectins encompassing all known sugar specificities. Cell surface carbohydrates of the various T. cruzi stages were analyzed by agglutination and lectin-binding assays. Specific receptors for wheat germ agglutinin (WGA), Helix pomatia, Sophora japonica, and Bandeiraea simplicifolia lectin II were found only in culture epimastigotes, whereas peanut agglutinin (PNA) sites were present exclusively in amastigotes, those for Phaseolus vulgaris in bloodstream trypomastigotes and amastigotes, and for Wistaria floribunda hemagglutinin predominantly in culture forms of T. cruzi. The N-acetylgalactosamine (DGalNAc)-binding lectin from Bauhinia purpurea agglutinated and inhibited the movement of epimastigotes and bloodstream trypomastigotes, but it only inhibited--without agglutinating--culture trypomastigotes. Because both the agglutination and inhibition of movement were reversed by specific sugar haptens, Bauhinia purpurea sites were present in all the flagellated parasites. On the other hand, PNA sites were detectable on epimastigotes after the cells were treated with sialidase, whereas, at the same time, WGA receptors were completely removed and those for the other sialic acid-binding proteins, Aaptos papillata lectin II and Limulus polyphemus, were partially eliminated; moreover, the activity of Wistaria floribunda hemagglutinin, a DGalNAc-binding lectin, increased 4,000 times. Trypsinization and lyzozyme treatment of epimastigote cells did not significantly affect lectin agglutination or lectin binding. WGA reacted solely with sialic acid residues on epimastigote cell surface with an apparent association constant of 2 x 10(6) M-1, each epimastigote having an estimated average of 3 x 10(6) WGA sites, as determined by binding experiments and a minimum of 7.7 x 10(6) sialic acid residues, as calculated by colorimetric method after sialidase digestion. Evidences are presented that the sialyl residues are rapidly regenerated (in approximately 4 h) and that they, at least for the most part, are not adsorbed from the culture medium. The receptor for the D-mannose-binding lectins (concanavalin A [Con A] and Lens culinaris) must either be on the same carbohydrate moiety having the WGA site, or, if in a distinct molecule, both carrier molecules of Con A and WGA sites must be located close to each other in the plasma membrane of the parasite.
