A C-type lectin induces NLRP3 inflammasome activation via TLR4 interaction in human peripheral blood mononuclear cells. Cell Mol Life Sci 2023; 80:188. [PMID: 37349530 PMCID: PMC11073222 DOI: 10.1007/s00018-023-04839-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 05/17/2023] [Accepted: 06/14/2023] [Indexed: 06/24/2023]
Abstract
Lectins are a large group of proteins found in many snake venoms. BjcuL is a C-type lectin from Bothrops jararacussu snake venom that does not present cytotoxicity action on human peripheral blood mononuclear cells (PBMCs) at concentrations of 5 and 10 μg/mL. BjcuL demonstrates an immunomodulatory role in PBMCs with the production of pro- and anti-inflammatory cytokines (IL-2, IL-10, IFN-γ, IL-6, TNF-α, and IL-17) in addition to stimulate T cells to produce reactive oxygen species (ROS) that could play a role in the acute inflammatory reaction observed in the victims. Inflammasomes are an essential arm in cells of innate immunity to detect and sense a range of endogenous or exogenous, sterile, or infectious stimuli to elicit cellular responses and effector mechanisms. NLRP3 inflammasome is a significant target for this study, because the lectin is responsible for leukocyte activation stimulating the release of inflammatory mediators, which results in dynamic cellular responses to remove the detrimental process to the body in snakebites. Thus, this study aimed to investigate how isolated BjcuL from B. jararacussu venom affects NLRP3 inflammasome activation on PBMCs. For this, the cells were isolated by density gradient and incubated with BjcuL at different periods and concentrations for the evaluation of the activation of the NLRP3 inflammasome through gene and protein expressions of ASC, CASPASE-1, and NLRP3 by RT-qPCR, Western blot, and immunofluorescence, as well as the participation of Toll-like receptor 4 (TLR4) and ROS in the IL-1β production, a product resultant of the NLRP3 inflammasome activation. Herein, BjcuL interacts with TLR4 as demonstrated by in vitro and in silico studies and induces cytokines release via NF-κB signaling. By genic and protein expression assays, BjcuL activates NLRP3 inflammasome, and the pharmacological modulation with LPS-RS, an antagonist of TLR4; LPS-SM, an agonist of TLR4; MCC950, a specific NLRP3 inhibitor, and rotenone, an inhibitor of mitochondrial ROS, confirmed the participation of TLR4 and ROS in the NLRP3 inflammasome activation and IL-1β liberation. The effects of BjcuL on the regulation and activation of the NLRP3 inflammasome complex via TLR4 activation with ROS participation may be determinant for the development of the inflammatory local effects seen in snakebite victims. In addition, in silico together with in vitro studies provide information that may be useful in the rational design of TLR agonists as well as new adjuvants for immunomodulatory therapy.

Evidence that BJcuL, a C-type lectin from Bothrops jararacussu venom, influences deubiquitinase activity, resulting in the accumulation of anti-apoptotic proteins in two colorectal cancer cell lines. Int J Biol Macromol 2022; 209:1205-1210.

Abstract
BJcuL is a snake venom C-type lectin (SVCTL) purified from the snake's venom Bothrops jararacussu. It has been previously demonstrated that BJcuL induces the accumulation of pro-apoptotic proteins of the extrinsic pathway, such as FADD and caspase-8, in the colorectal cancer cell line HT29, suggesting that the lectin may be able to enhance TRAIL-induced apoptosis. To test this hypothesis, we exposed two colorectal cancer cell lines, HT29 and HCT116, to increasing concentrations of BJcuL (1-20 μg/mL) in the presence or absence of TRAIL. Contrary to our expectations, however, BJcuL was unable to induce apoptosis in these cells, as shown by annexin-V/7AAD, clonogenic assays, and immunoblotting. Nevertheless, BJcuL was able to induce the accumulation of FADD and caspase-8, as well as anti-apoptotic proteins such as c-FLIP and survivin and poly-ubiquitinated proteins. Incubation with the deubiquitinase inhibitor WP1130 (10 μM) resulted in decreased BJcuL-induced survivin levels. Altogether, our results evince the effects of SVCTL on the ubiquitin-proteasome system in vitro for the first time. Compounds that can influence such system are important tools in the search for new therapeutic or diagnostic targets in cancer since they can elucidate the molecular mechanisms involved in determining cell fate as well as contributing to drug-development strategies in partnership with the pharmaceutical industry.

Abstract
The excessive production of inflammatory mediators results in an overactive immune response leading to the worsening of various human diseases. Thus, there is a still need to identify molecules able to regulate the inflammatory response. Lebecetin, a C-type lectin protein isolated from Macrovipera lebetina snake venom, was previously characterized as a platelet aggregation inhibitor and antitumor active biomolecule. In the present work, we investigated its effect on the production of some cytokines linked to inflammatory response and the underlying mechanisms in lipopolysaccharide (LPS)-induced THP1 macrophages. Interestingly, we found that lebecetin reduced the levels of the pro-inflammatory cytokines TNF-α, IL-6, and IL-8 while it partially increased LPS-induced secretion of the immunomodulatory cytokine IL-10. Furthermore, this modulatory effect was accompanied by decreased activation of ERK1/2, p38, AKT kinases and NF-κB along with reduced expression of αvβ3 integrin. Thus, this study highlights the promising role of lebecetin as a natural biomolecule that could manage the inflammatory response involved in the development and progression of inflammatory diseases.

Abstract
BACKGROUND Neuroblastoma is a pediatric tumor with a mortality rate of 40% in the most aggressive cases. Tumor microenvironment components as immune cells contribute to the tumor progression; thereby, the modulation of immune cells to a pro-inflammatory and antitumoral profile could potentialize the immunotherapy, a suggested approach for high-risk patients. Preview studies showed the antitumoral potential of BJcuL, a C- type lectin isolated from Bothrops jararacussu venom. It was able to induce immunomodulatory responses, promoting the rolling and adhesion of leukocytes and the activation of neutrophils. METHODS SK-N-SH cells were incubated with conditioned media (CM) obtained during the treatment of neutrophils with BJcuL and fMLP, a bacteria-derived peptide highly effective for activating neutrophil functions. Then we evaluated the effect of the same stimulation on the co-cultivation of neutrophils and SK-N-SH cells. Tumor cells were tested for viability, migration, and invasion potential. RESULTS In the viability assay, only neutrophils treated with BJcuL (24 h) and cultivated with SK-N-SH were cytotoxic. Migration of tumor cells decreased when incubated directly (p < 0.001) or indirectly (p < 0.005) with untreated neutrophils. When invasion potential was evaluated, neutrophils incubated with BJcuL reduced the total number of colonies of SK-N-SH cells following co-cultivation for 24 h (p < 0.005). Treatment with CM resulted in decreased anchorage-free survival following 24 h of treatment (p < 0.001). CONCLUSION Data demonstrated that SK-N-SH cells maintain their migratory potential in the face of neutrophil modulation by BJcuL, but their invasive capacity was significantly reduced.

Inflammation and coagulation crosstalk induced by BJcuL, a galactose-binding lectin isolated from Bothrops jararacussu snake venom. Int J Biol Macromol 2019; 144:296-304.

Abstract
Inflammation and coagulopathies are important systemic events following snakebite. Snake venom galactoside-binding lectins (SVgalLs) are known modulators of the immune response with no direct effect on hemostasis. Considering the crosstalk between inflammation and coagulation, the present study investigated how BJcuL, a proinflammatory SVgalL isolated from Bothrops jararacussu venom, mediated the inflammation-induced procoagulant activity. We examined the proinflammatory cytokine production and procoagulant tissue factor (TF) activity in human whole blood and monocyte-rich cell suspension (MR-PBMC) treated with BJcuL. This lectin increased production of the cytokines TNF-α, IL-1β and IL-6, upregulated TF expression on the cell surface, and induced procoagulant activity. The proinflammatory behavior was mediated by the direct interaction between the lectin and toll-like receptor 4, via binding to β-galactoside-containing glycoconjugates on the cell surface, and activation of NFκ-B signaling. Interestingly, the BJcuL-induced inflammation was directly associated with the procoagulant activity of MR-PBMC cells. In whole blood culture, the lectin exhibited similar behavior, i.e. it induced cytokine production and MR-PBMC TF-mediated procoagulant activity. Therefore, the present study is the first report on the inflammation-induced procoagulant activity of SVgalLs, and it indicates that BJcuL is an important factor associated with coagulopathy in patients with snake envenomation.

Abstract
Envenomation by viperid snakes is characterized by systemic thrombotic syndrome and prominent local inflammation. To date, the mechanisms underlying inflammation and blood coagulation induced by Viperidae venoms have been viewed as distinct processes. However, studies on the mechanisms involved in these processes have revealed several factors and signaling molecules that simultaneously act in both the innate immune and hemostatic systems, suggesting an overlap between both systems during viper envenomation. Moreover, distinct classes of venom toxins involved in these effects have also been identified. However, the interplay between inflammation and hemostatic alterations, referred as to thromboinflammation, has never been addressed in the investigation of viper envenomation. Considering that platelets are important targets of viper snake venoms and are critical for the process of thromboinflammation, in this review, we summarize the inflammatory effects and mechanisms induced by viper snake venoms, particularly from the Bothrops genus, which strongly activate platelet functions and highlight selected venom components (metalloproteases and C-type lectins) that both stimulate platelet functions and exhibit pro-inflammatory activities, thus providing insights into the possible role(s) of thromboinflammation in viper envenomation.

Abstract
The biological activities observed upon envenomation by Scorpaena plumieri could be linked to both the venom and the skin mucus. Through a proteomic/functional approach we analyzed protein composition and biological activities of the venom and skin mucus. We identified 885 proteins: 722 in the Venomous Apparatus extracts (Sp-VAe) and 391 in the Skin Mucus extract (Sp-SMe), with 494 found exclusively in Sp-VAe, being named S. plumieri Venom Proteins (Sp-VP), while 228 were found in both extracts. The majority of the many proteins identified were not directly related to the biological activities reported here. Nevertheless, some were classified as toxins/potentially interesting molecules: lectins, proteases and protease inhibitors were detected in both extracts, while the pore-forming toxin and hyaluronidase were associated with Sp-VP. Proteolytic and anti-microbial activities were linked to both extracts, while the main toxic activities - cardiovascular, inflammatory, hemolytic and nociceptive - were elicited only by Sp-VAe. Our study provided a clear picture on the composition of the skin mucus and the venom. We also show that the classic effects observed upon envenomation are produced by molecules from the venomous gland. Our results add to the growing catalogue of scorpaeniform fish venoms and their skin mucus proteins. SIGNIFICANCE In this study a large number of proteins - including classical and non-classical toxins - were identified in the venomous apparatus and the skin mucus extracts of the Scorpaena plumieri fish through shotgun proteomic approach. It was shown that the toxic effects observed upon envenomation are elicited by molecules originated from the venomous gland. These results add to the growing catalogue of scorpaeniform fish venoms and their skin mucus proteins - so scarcely explored when compared to the venoms and bioactive components of terrestrial animals. Data are available via ProteomeXchange with identifier PXD009983.

Abstract
BjcuL is a C-type lectin with specificity for the binding of β-d-galactose units isolated from Bothrops jararacussu venom. It triggers cellular infiltration in post capillary venules, increases edema and vascular permeability in murine models, contributes to in vitro neutrophil activation and modulates macrophage functional activation towards an M1 state. The purpose of this study was to investigate the effect of BjcuL on human peripheral blood mononuclear cells (PBMCs) activation with a focus on PBMCs proliferation and inflammatory mediators release. Results showed that BjcuL is not toxic to PBMCs, that BjcuL inhibits PBMCs proliferation and that it stimulates PBMCs to produce superoxide anion and hydrogen peroxide, primarily via lymphocyte stimulation, but does not stimulate the production of nitric oxide and PGE2. These results demonstrate that BjcuL has an immunomodulatory effect on PBMCs. Further studies are needed to confirm the immunomodulatory effect of BjcuL, to elucidate the molecular mechanisms of action responsible for its effects and to determine its potential application as an immunopharmacological and biotechnological tool.
