Kaygorodova IA. Role of Antimicrobial Peptides in Immunity of Parasitic Leeches. DOKLADY BIOLOGICAL SCIENCES : PROCEEDINGS OF THE ACADEMY OF SCIENCES OF THE USSR, BIOLOGICAL SCIENCES SECTIONS 2023; 511:183-195. [PMID: 37833572 DOI: 10.1134/s0012496623700436] [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: 01/20/2023] [Revised: 03/21/2023] [Accepted: 03/25/2023] [Indexed: 10/15/2023]
Abstract
The review summarizes the current state of knowledge about leech immunity, with emphasis on the special role of antimicrobial peptides (AMPs), and highlights the wide variety of primary AMP structures, which seem to correlate with a variety of life strategies and the ecology of ectoparasites. Antimicrobial proteins and AMPs are a diverse class of natural molecules that are produced in all living organisms in response to an attack by a pathogen and are essential components of the immune system. AMPs can have a wide range of antibiotic activities against foreign and opportunistic bacteria, fungi, and viruses. AMPs play an important role in selection of colonizing bacterial symbionts, thus helping multicellular organisms to cope with certain environmental problems. AMPs are especially important for invertebrates, which lack an adaptive immune system. Although many AMPs are similar in physicochemical properties (a total length from 10 to 100 amino acids, a positive total charge, or a high cysteine content), their immunomodulatory activities are specific for each AMP type.

Abstract
It is known that earthworm coelomic fluid (CF) can affect not only cancer but also normal cells. The study demonstrated that the CF of the earthworm Dendrobaena veneta exhibited cytotoxicity against A549 lung cancer cells but did not toward the bronchial epithelial cell line BEAS-2B. The selective effect on the tumor cells was achieved after a short-term CF heat pre-treatment at 70 °C. The cytotoxic effect of the CF was time- and concentration-dependent. The CF noticeably decreased the viability and affected the morphology of the A549 cells. Scanning electron microscopy revealed a different degree of destruction of the nucleus and cytoplasm of A549 cells. As determined by atomic force microscopy, the cell surface roughness increased while the cell stiffness was reduced upon the CF treatment. A twofold increase in the caspase 3, 4, 5, and 10 levels was observed in the A549 cells after the incubation with the CF. The results obtained by flow cytometry using Annexin V confirmed the proapoptotic effect of the earthworm CF on A549 lung cancer cells. The D. veneta CF and active fraction obtained with cytotoxicity toward A549 lung cancer is an interesting and promising preparation for further biological, chemical, and biomedical research.

Abstract
Invertebrate immunity is associated with natural mechanisms that include cellular and humoral elements, similar to those that play a role in vertebrate innate immune responses. Formation of extracellular traps (ETs) is a newly discovered mechanism to combat pathogens, operating not only in vertebrate leucocytes but also in invertebrate immune cells. The ET components include extracellular DNA (exDNA), antimicrobial proteins and histones. Formation of mammalian ETs depends on enzymes such as neutrophil elastase, myeloperoxidase, the citrullination of histones and protease activity. It was confirmed that coelomocytes-immunocompetent cells of the earthworm Eisenia andrei-are also able to release ETs in a protease-dependent manner, dependent or independent of the formation of reactive oxygen species and rearrangement of the cell cytoskeleton. Similar to vertebrate leukocytes (e.g., neutrophil), coelomocytes are responsible for many immune functions like phagocytosis, cytotoxicity and secretion of humoral factors. ETs formed by coelomocyte analogues to neutrophil ETs consist of exDNA, histone H3 and attached to these structures proteins, e.g., heat shock proteins HSP27. The latter fact confirms that mechanisms of ET release are conserved in evolution. The study on Annelida adds this animal group to the list of invertebrates capable of ET release, but most importantly provides insides into innate mechanisms of ET formation in lower animal taxa.

Abstract
Due to the specific habitat conditions in which they live, earthworms are constantly exposed to pathogens. Consequently, they have evolved various immuno-defense mechanisms, including cellular (coelomocytes) and humoral responses, which may help to eliminate deleterious micro-organisms but also repair and/or protect host cells and tissues. Similar to mammalian phagocytes, coelomocytes can kill ingested pathogens with reactive oxygen species (ROS) and nitric oxide. In the present work, we studied the effects of the dermal exposure of Eisenia andrei earthworms to different immuno-stimulants: phorbol-12-myristate-13-acetate (PMA), lipopolysaccharide (LPS) or concanavalin A (ConA). After 3 days of treatment with all immuno-stimulants, decreased numbers and changed composition of the coelomocytes were observed. The immuno-stimulants also induced numerous changes in bactericidal activity, including ROS production. Furthermore, all stimulants increased cell proliferation while only LPS-treatment significantly elevated apoptosis of coelomocytes. These results demonstrate that in vivo treatment of earthworms with immuno-stimulants induces various changes in their coelomocyte response.

Abstract
Despite intense study in mammals, the different roles played by the immune system in detecting (immunosurveillance), controlling and remodeling (immunoediting) neoplasia, and perhaps in metastasis are not fully understood. In this review, I will present evidence of neoplasia and invasive malignancy, as well as tumor immunity in invertebrates and nonmammalian vertebrates. I will also present a comparative and evolutionary view of the complex interactions between neoplasia and the host immune system. Overall, I wish to go beyond the too simplistic dichotomy between invertebrates with innate immunity that are only affected with benign neoplasia and vertebrates with adaptive immunity that are affected by metastatic malignancies or cancer.

Abstract
Earthworms belonging to oligochaete annelids became a model for comparative immunologists in the early sixties with the publication of results from transplantation experiments that proved the existence of self/nonself recognition in earthworms. This initiated extensive studies on the earthworm immune mechanisms that evolved to prevent the invasion of pathogens. In the last four decades important cellular and humoral pathways were described and numerous biologically active compounds were characterized and often cloned.

Abstract
Natural killer (NK) activity has been examined in birds for over 30 years, but evidence that avian NK activity plays crucial roles in disease is only suggestive. In chickens, NK activity is mediated by TCR0 cells in the intestinal epithelium, but elsewhere subsets of alphabeta and gammadelta T cells (NKT cells) may be more important. There are few lectin-like NK receptor genes, located in the genomic region syntenic with the natural killer complex (NKC) as well as the major histocompatibility complex (MHC). In contrast, a huge number of Ig-like receptor genes are located in a region syntenic with the leukocyte receptor complex (LRC).

Abstract
Earthworms irritated naturally (e.g. by predators) or experimentally extrude coelomocyte-containing coelomic fluid through the dorsal pores of the body wall. In the present study, the earthworms, Dendrobaena veneta, experimentally depleted of free-floating coelomocytes by multiple electric shocks (1 min, 4.5 V) remained fully vital and coelomocyte depletion was followed by the extensive cell replenishment, which was more efficient in the case of amoebocytes than autofluorescent eleocytes/chloragocytes, quantified by flow cytometry. Immunohistochemical procedure with antibodies against human Ki-67 proliferation antigens revealed proliferating cells on cytospin preparations of coelomocytes extruded by electric shock. Quantification of proliferating cells in the suspension of extruded coelomocytes was performed by flow cytometry on FL-2 profiles of propidium iodide-stained samples; riboflavin-derived autofluorescence of eleocytes/chloragocytes was lost during detergent treatment. As expected, the percentage of coelomocytes proliferating in coelomic fluid was increased during restoration of coelomocyte number after experimental depletion. The method described here may be very useful for investigations of antigen-driven proliferation of earthworm coelomocytes.

Abstract
Adaptive immunity has often been considered the penultimate of immune capacities. That system is now being deconstructed to encompass less stringent rules that govern its initiation, actual effector activity, and ambivalent results. Expanding the repertoire of innate immunity found in all invertebrates has greatly facilitated the relaxation of convictions concerning what actually constitutes innate and adaptive immunity. Two animal models, incidentally not on the line of chordate evolution (C. elegans and Drosophila), have contributed enormously to defining homology. The characteristics of specificity and memory and whether the antigen is pathogenic or nonpathogenic reveal considerable information on homology, thus deconstructing the more fundamentalist view. Senescence, cancer, and immunosuppression often associated with mammals that possess both innate and adaptive immunity also exist in invertebrates that only possess innate immunity. Strict definitions become blurred casting skepticism on the utility of creating rigid definitions of what innate and adaptive immunity are without considering overlaps.

Abstract
Multicellular organisms including invertebrates and vertebrates live in various habitats that may be aquatic or terrestrial where they are constantly exposed to deleterious pathogens. These include viruses, bacteria, fungi, and parasites. They have evolved various immunodefense mechanisms that may protect them from infection by these microorganisms. These include cellular and humoral responses and the level of differentiation of the response parallels the evolutionary development of the species. The first line of innate immunity in earthworms is the body wall that prevents the entrance of microbes into the coelomic cavity that contains fluid in which there are numerous leukocyte effectors of immune responses. When this first barrier is broken, a series of host responses is set into motion activating the leukocytes and the coelomic fluid. The responses are classified as innate, natural, non-specific, non-anticipatory, non-clonal (germ line) in contrast to the vertebrate capacity that is considered adaptive, induced, specific, anticipatory and clonal (somatic). Specific memory is associated with the vertebrate response and there is information that the innate response of invertebrates may under certain conditions possess specific memory. The invertebrate system when challenged affects phagocytosis, encapsulation, agglutination, opsonization, clotting and lysis. At least two major leukocytes, small and large mediate lytic reactions against several tumor cell targets. Destruction of tumor cells in vitro shows that phagocytosis and natural killer cell responses are distinct properties of these leukocytes. This has prompted newer searches for immune function and regulation in other systems. The innate immune system of the earthworm has been analyzed for more than 40 years with every aspect examined. However, there are no known entire sequences of the earthworm as exists in these other invertebrates. Because the earthworm lives in soil and has been utilized as a successful monitor for pollution, there are studies that reveal up and down regulation of responses in the immune system after exposure to a variety of environmental pollutants. Moreover, there are partial sequences that appear in earthworms after exposure to environmental pollutants such as cadmium and copper. There are now attempts to define the AHR receptor crucial for intracellular signaling after exposure to pollutants, but without linking the signals to changes in the immune system. There are several pathways for signal transduction, including JAK/STAT, TOLL, TRAF PIP3, known in invertebrates and vertebrates. For resistance to pathogens, conserved signal transduction components are required and these include a Toll/IL-1 receptor domain adaptor protein that functions upstream of a conserved p38 MAP kinase pathway. This pathway may be an ancestral innate immune signaling pathway found in a putative common ancestor of nematodes, arthropods and even vertebrates. It could also help us to link pollution, innate immunity and transduction in earthworms.

Abstract
Earthworm innate immunity depends upon small and large leukocytes (coelomocytes) that synthesize and secrete humoral antimicrobial molecules (e.g. lysenin, fetidin, eiseniapore, coelomic cytolytic factor [CCF]; Lumbricin I). Small coelomocytes (cytotoxic) are positive (CD11a, CD45RA, CD45RO, CDw49b, CD54, beta(2)-m and Thy-1 [CD90]; CD24; TNF-alpha) but negative using other mammalian markers. Large coelomocytes (phagocytic) are uniformly negative. Specific earthworm anti-EFCC 1, 2, 3, 4 mAbs are negative for Drosophila melanogaster hemocytes and mammalian cells but positive those of earthworms. Coelomocytes contain several lysosomal enzymes involved in phagocytosis and a pattern recognition molecule (CCF) that may trigger the prophenoloxidase cascade a crucial innate immune response. Earthworms and other invertebrates possess natural, non-specific, non-clonal, and non-anticipatory immune response governed by germ line genes. Toll and Toll-like receptor signaling is essential for phagocytosis and antimicrobial peptide synthesis and secretion in insects and vertebrates but has not yet been shown to be essential in earthworm innate responses.

Abstract
Earthworm coelomic fluid contains biologically active molecules and leukocytes that participate in phagocytosis, encapsulation. Presumably they synthesize and secrete several effector modulators of innate immune responses such as antibacterial molecules, cytotoxic proteins and cytokines. Several lytic molecules have been detected in coelomic fluid previously but it is not yet clear which are actually released from the coelomocytes. Our aim was to analyze the cytotoxic effects of coelomocytes on mammalian target cells and to provide evidence that the lytic factors originate from coelomocytes. Cell-free coelomic fluid, supernatants of short-term cultured coelomocytes, and lysates from coelomocytes--derived by mechanical and detergent extraction--were used in cytotoxicity assays performed on different mammalian standard tumor cell lines and mouse fibroblasts. We used native and denaturized (using proteinase K, and trypsin digestions, or heat-inactivation) coelomocyte lysates (CCL). The viability controls of targeted cells were made by measuring photometrically and analyzing by inverted microscopy. According to our results the coelomic fluid, the supernatant of cultured coelomocytes, and the CCL significantly decreased ratios of living cells compared to controls in a dose-dependent manner. Our experiments performed with CCLs suggest that coelomocytes are responsible for the productions of cytotoxic components presumably proteins.

Abstract
There is mounting evidence that earthworms could be used as a sentinel species for soil ecotoxicity evaluation. In this aspect, phagocytosis by coelomocytes was shown to be a sensitive biomarker of exposure to xenobiotics. In this paper, we introduce a simple method for ultrasound extrusion of earthworm coelomocytes that generates a high cell yield, does not interfere with phagocytic competence, and requires a minimum of manipulations. Coelomocytes were extruded from the earthworm Eisenia fetida using this new ultrasound method and compared with ethanol and electrical extrusion. The ultrasonic extrusion showed the highest cell recovery with 3.17 +/ -0.8 x 10(6) cells per earthworm compared with 2.22 +/- 0.8 x 10(6) cells per earthworm for electrical extrusion and 1.57 +/- 0.07 x 10(6) cells per earthworm for ethanol extrusion. No significant differences in the cell viability were observed using propidium iodide and flow cytometry with viability for extrusion with ethanol of 63.8 +/- 12.7%, electrical 76.8 +/- 7.5%, and ultrasound 68.2 +/- 7.8%. To compare the potential effect of extrusion on cell quality, the cells extruded using the three methods were subjected to an 18-h in vitro exposure to methylmercury chloride (MeHgCl; CH3HgCl) with concentrations ranging from 10(-9) to 10(-4)M. The half-maximal effective concentration (EC50) for inhibition of phagocytosis occurred between 10(-7) and 10(-6)M. We found no significant differences among the extrusion methods for the phagocytic potential of the coelomocytes. This method does not harm the worms and can certainly improve collection of coelomocytes from earthworms and therefore contribute to the development of bioassays using invertebrates.

Abstract
Immune systems are, increasingly, being studied from comparative perspectives. The analysis of the immune-defense systems of invertebrates, such as fruit flies and earthworms, is an important part of this effort. These systems are innate, natural non-specific, non-anticipatory and non-clonal. This is in contrast to the macrophage T and B systems that characterize vertebrate adaptive immunity whose properties can be categorized as adaptive, induced, specific, anticipatory, and clonal. In this review, we will focus on the earthworm system. Earthworms, like other complex invertebrates, possess several leukocyte types and synthesize and secrete a variety of immunoprotective molecules. The system as a whole effects phagocytosis, encapsulation, agglutination, opsonization, clotting and lysis of foreign components. At least two major leukocytes, small coelomocytes, and large coelomocytes mediate lytic reactions against several targets. Destruction of tumor cells in vitro shows that phagocytosis and natural killer cell responses are distinct properties of coelomocytes. A third type, the chlorogogen cell, synthesizes and sheds effector lytic molecules. Among the lytic molecules, three have been identified and sequenced (fetidins, CCF-1, lysenin) and another has been discovered (eiseniapore), while three other molecules, H(1) H(2) H(3), share agglutinating and lysing functions. In contrast to these, Lumbricin I is the only known molecule of the earthworm system that is antimicrobial but non-lytic. Altogether the cellular and humoral components of the earthworm system function to distinguish between self and not self, dispose of internal (cancer?), damaged components and external antigens (microbes). The evolutionary context of the earthworm innate immune system is discussed at the end of this article.

Abstract
Earthworm (Eisenia fetida) coelomic fluid contains several leukocytes (coelomocytes): basophils, acidophils and neutrophils as well as chloragocytes. Small coelomocytes and coelomocyte lysate are cytotoxic for the tumor cell target K562. The expression of a lytic factor was investigated by immunocytochemistry using light and transmission electron microscopy. A rat-anti-mouse-perforin-mAb labeled mainly small coelomocytes (nearly 20%) as visualized by light microscopy. TEM analysis using immunogold showed a homogenous labeling in the cytoplasm of small coelomocytes. The highest number of immunogold particles was estimated in coelomocytes with many small cytoplasmic granules. Coelomocytes with large lysosomal granules were also labeled but less intensely. No antibody binding was observed for chloragocytes either in light or electron microscopy. This suggests that the perforin-like activity is associated with only one cell type and that chloragocytes are responsible for other lytic activities. MALDI-MS revealed calreticulin usually associated with perforin in mammalian cells that mediate lysis (e.g. NK, CTL). Together, results strongly suggest the presence of putative perforin in earthworms. This in turn supports the hypothesis that perforin is a conserved component important in immune defense during evolution.

Abstract
Although lacking the components that characterize the acquired immunity systems of vertebrates, invertebrates nevertheless possess effective general innate immune mechanisms which exhibit striking parallels with those of vertebrates. These innate immune systems include both cellular and humoral elements. Invertebrate phagocytes synthesize both oxygen-dependent and oxygen-independent molecules to combat infectious agents. Cytotoxic substances employed by invertebrates include reactive intermediates of oxygen and nitrogen, antimicrobial peptides, lectins, cytokine- and complement-like molecules, and quinoid intermediates of melanin. The signal transduction pathways that are involved in mediating the production of these substances appear to be very similar among animal species, suggesting a common ancestral origin for the innate immune systems.

Abstract
Cells involved in leech inflammatory responses have been characterized by morphological, histochemical, and immunohistochemical methods. Macrophage-like cells, NK-like cells, and granulocytes migrated shortly after injury by pricking with bacterial lipopolysaccharide. Inflammatory responses increased progressively and provoked cell migration to the body wall and then to wound surfaces. Macrophages, NK cells, and granulocytes display similar features and behavior traits in invertebrates and vertebrates.

Abstract
The cytolytic protein Eiseniapore (38 kDa) from coelomic fluid of the earthworm Eisenia fetida functionally requires sphingomyelin as revealed by using mammalian erythrocytes and phospholipid vesicles. The effects of ions, glycoproteins and phospholipids were investigated for the two-step Eiseniapore action mode, binding and pore formation in different assays. Eiseniapore lysis is activated by thiol groups but inhibited by metal ions. Eiseniapore binding to target membranes is inhibited by Eiseniapore-regulating factor, vitronectin, heparin and lysophosphatidylcholine. Ca2+ and Mg2+ were found to be not necessary for membrane binding or lytic activity. Sphingomyelin was essential for Eiseniapore-induced leakage of liposomes. We describe a cytolytic protein/toxin in Eiseniapore which differs from the established classification; it can be activated by thiol groups and is inhibited by sphingomyelin. Electron microscopy of erythrocyte membranes confirmed ring-shaped structures (pores) with a central channel with outer (10 nm) and inner (3 nm) diameters as shown previously [Lange, S., Nüssler, F., Kauschke, E., Lutsch, G., Cooper, E.L. & Herrmann, A. (1997) J. Biol. Chem. 272, 20 884-20 892] using artificial membranes. Functional evidence of pore formation by Eiseniapore was revealed as protection of lysis by carbohydrates occurred at an effective diameter above 3 nm. From these results, we suggest a plausible explanation for the mechanism by which components of the earthworm's immune system destroy non-self components.

Abstract
In the earthworm's immune system, cell adhesion, which occurs by putative receptors on leukocytes, is essential after recognition of self vs. non-self. Confrontation with foreign antigens is a normal event in the environment, replete with microbial pathogens that pose a threat to survival. To better understand what happens when an effector cell first recognizes a foreign target followed by its adhesion to it, isolated leukocytes, in sufficient quantities to be subjected to various analyses, have been extremely beneficial. In vitro approaches when accompanied by biochemical, immunological, and molecular technologies, have opened up new vistas concerning the immune response of earthworms and other invertebrates. The most recent discovery includes the preliminary identification of cell differentiation (CD) markers that play vital roles in recognitive and adhesive events. Certain leukocyte effectors show characteristics of natural killer (NK) cells that may act differently depending upon their source, whether autogeneic, allogeneic, xenogeneic, or expressed under normal or varying environmental conditions including exposure to xenobiotics. At the level of earthworm evolution, there is apparently a dissociation of phagocytosis from the process of killing by NK-like effectors. There are at least three future challenges. First, it is essential to determine the precise nature of the CD markers with respect to their molecular structure. Second, once their molecular and biochemical characteristics have been defined, the role of these markers in cellular and humoral mechanisms must be clarified in order to define effector cell products and resulting immune responses. Third, there is a need to differentiate between the several lytic factors that have been found in earthworms with respect to molecular structure, and biochemical and functional characterization.

Abstract
Coelomic fluid of earthworms contains a 42 kDa protein designated CCF-1 (coelomic cytolytic factor 1), which accounts for approximately 40% of cytolytic activity of the entire coelomic fluid. CCF-1 was documented to be present on cells of the mesenchymal lining of the coelomic cavity as well as on free coelomocytes. Both cellular and humoral levels of CCF-1 were significantly increased after parenteral injection of endotoxin. Moreover, CCF-1 seems to be involved in cell mediated cytotoxicity, because cytotoxic activity is blocked in the presence of anti-CCF-1 monoclonal antibody (mAb).

Abstract
Lytic activity in the coelomic fluid of earthworm (Eisenia fetida fetida) has been ascribed to eiseniapore, a hemolytic protein of 38 kDa. Since receptors for eiseniapore on target cell membranes are not known, we used lipid vesicles of various composition to determine whether specific lipids may serve as receptors. Lytic activity of eiseniapore was probed by the relief of fluorescence dequenching from the fluorophore 8-aminonaphthalene-1,3, 6-trisulfonic acid originally incorporated into the vesicle lumen as a complex with p-xylene-bis-pyridinium bromide. Hemolysin binds to and disturbs the lipid bilayer only when distinct sphingolipids consisting of a hydrophilic head group as phosphorylcholine or galactosyl as well as the ceramide backbone, e.g. sphingomyelin, are present. Cholesterol enhances eiseniapore lytic activity toward sphingomyelin-containing vesicles probably due to interaction with sphingomyelin. Leakage of vesicles was most efficient when the lipid composition resembled that of the outer leaflet of human erythrocytes. Presumably, an oligomeric protein pore formed by six monomers is responsible for leakage of sphingomyelin-containing vesicles. The secondary structure of eiseniapore did not change upon binding to lipid membranes. The lytic activity of eiseniapore was completely abolished after its denaturation or after preincubation with polyclonal antibodies. Our results suggest that the presence of specific sphingolipids is sufficient to mediate lytic activity of eiseniapore. This action contributes to our understanding of earthworm immune responses.

Abstract
In vertebrates, including man, the study of stress has contributed substantially to unravelling the complex relationship between immune-neuroendocrine interactions and the systems involved. On the basis of data on the presence and distribution of the main actors (POMC products, cytokines, biogenic amines, and steroid hormones) in different species and taxa from invertebrates to vertebrates, we argue that these responses have been deeply connected and interrelated since the beginning of life. Moreover, the study of nitric oxide suggests that the inflammatory reaction is located precisely between the immune and stress responses, sharing the same fundamental evolutionary roots. The major argument in favor of this hypothesis is that the immune, stress, and inflammation responses appear to be mediated by a common pool of molecules that have been conserved throughout evolution and that from a network of adaptive mechanisms. One cell type, the macrophage, appears to emerge as that most capable of supporting this network critical for survival; it was probably a major target of selective pressure. All these data fit the unitarian hypothesis we propose, by which evolution favors what has been conserved, rather than what has changed, as far as both molecules and functions are concerned.
