Abstract
Plasma membrane anchored nucleotidases (E-ATPDases), as the E-NTPDase family, could hydrolyze and regulate the pericellular levels of nucleotides in lymphocytes. Each immune organ has a different microenvironment and display lymphocytes with different functions and phenotypes. Considering the different functions of each resident subpopulations of lymphocytes, the E-ATPDases activities in bone marrow (BML), thymus (TL) and mesenteric lymph node (MLL) lymphocytes of Wistar rats were characterized. The hydrolysis of extracellular nucleotides (eATP and eADP) showed linearity in time of reaction between 0 and 120 min, and concentration of lymphocytes expressed in proteins between 1 and 6 μg protein in the reaction medium. The optimal activity was attained at 37 °C in a pH value of 8.0. The necessity of the cofactors Ca2+ and Mg2+ for the enzymatic activity was confirmed through a curve of concentration of 0-1000 µM in the reaction medium, with both cofactors showing similar effects in the enzymatic activity. The Chevillard plot revealed that the hydrolysis of eATP and eADP occurred at the same active site of the enzyme. The analyses of E-ATPDases inhibitor and enzyme specificity showed possible involvement of E-NTPDase isoforms - 1 and - 2 in the isolated cells. Furthermore, different kinetic behavior of the nucleotide hydrolysis in each resident subpopulation lymphocyte was observed in this study, as MLL showed the higher Vmax with the lowest km values, while TL had the lowest Vmax and high km values. The kinetic values for E-NTPDase activity of each immune tissue lymphocytes can be an important therapeutic target for numeral immune-related diseases.

Distinct kinetics for nucleotide hydrolysis in lymphocytes isolated from blood, spleen and cervical lymph nodes: Characterization of ectonucleotidase activity. Cell Biochem Funct 2021; 39:511-520. [PMID: 33783015 DOI: 10.1002/cbf.3616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 11/10/2020] [Accepted: 11/15/2020] [Indexed: 11/08/2022]
Abstract
Ectonucleotidases are a plasma membrane-bound enzyme that hydrolyses extracellular adenosine triphosphate (eATP) and adenosine diphosphate (eADP) to adenosine monophosphate (AMP). It regulates normal function of lymphocytes, acts as an inflammatory marker and represents a molecular target for new therapeutics. Thus, this study sought to isolate lymphocytes from blood (BL), spleen (SL) and cervical lymph node (CLL), and characterize the eATP and eADP enzymatic hydrolysis in Wistar rats. The hydrolysis of the nucleotides occurred primarily at pH 8.0, 37°C in the presence of Ca2+ or Mg2+ . Chevillard-plot showed the hydrolysis of eATP and eADP at the same active site. The inhibitors of some classical ATDPases did not cause any significant change on enzymatic activity. Inhibitors of E-NTPDase (-1, -2, -3 isoforms) and E-NPP-1 decrease the enzyme activity in all resident lymphocytes. Furthermore, kinetic parameters (Vmax and Km) revealed that SL had significantly (P < .001) higher enzymatic activity when compared to BL and CLL. In conclusion, this study standardized kinetic values for eATP and eADP hydrolysis for resident lymphocytes isolated from BL, SL and CLL.

Purinergic system as a potential target for inflammation and toxicity induced by thymol in immune cells and tissues. Mol Cell Biochem 2018; 452:105-110. [PMID: 30066040 DOI: 10.1007/s11010-018-3416-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Accepted: 07/28/2018] [Indexed: 12/13/2022]
Abstract
Thymol is a phytochemical component present in many plants used as food additive in order to promote animal growth due to its several biological properties. However, possible side effects of thymol remain poorly known limited to few reports. In this sense, we evaluated the enzymes of the purinergic signaling such as, ectonucleoside triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase and adenosine deaminase (ADA), that play an important role on toxicity induced by excessive adenosine triphosphate (ATP) content in the extracellular environment. Thus, the aim of this study was to evaluate whether purinergic signaling could be considered a potential target of thymol-induced inflammation, and the toxicity in tissues and immune cells of mice after thymol administration. NTPDase activity (ATP as substrate) in serum, spleen, and splenic lymphocytes was lower after 30 days of oral treatment at doses of 10, 20, and 40 mg/kg of thymol, while ADA activity was stimulated at 20 and 40 mg/kg. No differences were observed between groups regarding NTPDase (ADP as substrate) and 5'-nucleotidase activities in all evaluated tissues. Based on these evidences, adenine nucleotide hydrolysis is modified in serum, spleen, and splenic lymphocytes of mice treated with thymol, contributing to inflammation and toxicity by a reduction on ATP hydrolyses and its possible accumulation in the extracellular medium and increased Ado desamination and its possible reduction in the extracellular environment, leading to a self-sustained pro-inflammatory deleterious cycle. In summary, all tested thymol concentrations induced inflammation and toxicity in tissues and immune cells of treated mice.

Ecto-enzymes activities in splenic lymphocytes of mice experimentally infected by Trypanosoma cruzi and treated with specific avian immunoglobulins: an attempt to improve the immune response. Mol Cell Biochem 2018; 448:9-15.

Abstract
The aim of this study was to evaluate the therapeutic efficacy of specific avian polyclonal antibodies (IgY) against Trypanosoma cruzi and their interaction with ecto-enzymes of the purinergic system (NTPDase and adenosine deaminase (ADA) activities) in splenic lymphocytes. For this, mice were divided into six groups: three non-infected (A, B, and C) and three infected (D, E, and F). The groups A and D were composed by negative and positive controls, respectively; while the groups B and E were treated prophylactically with IgY (50 mg/kg), and the groups C and F were treated therapeutically with IgY (50 mg/kg). Treatment with IgY reduced parasitemia on day 6 post-infection (PI) compared to the infected control group, but it was similar on day 8 PI. Moreover, infected and treated animals (the groups E and F) did not show neither amastigotes in the cardiac tissue nor cardiac lesions when compared to the positive control group (the group D). The E-NTPDase (ATP and ADP as substrate) and ADA activities in splenic lymphocytes increased significantly in the positive control group (the group D) compared to the negative control group (the group A). The therapeutic treatment of IgY (the group F) was able to prevent the increase of E-NTPDase and E-ADA activities compared to the positive control group (the group D), but this finding was not observed in animals that received the prophylactic treatment (the group E). The therapeutic treatment of IgY may be considered an interesting approach to improve the immune response of mice experimentally infected by T. cruzi.

Diphenyl diselenide modulates nucleotidases, reducing inflammatory responses in the liver of Toxoplasma gondii-infected mice. Purinergic Signal 2017; 13:489-496.

Abstract
The aim of this study was to verify the effect of diphenyl diselenide (PhSe)2 on hepatic nucleotidases and on the concentration of purines in mice infected by Toxoplasma gondii. The animals were divided into four groups: Group A (uninfected), Group B (uninfected and treated with (PhSe)2), Group C (infected), and Group D (infected and treated with (PhSe)2). The inoculation (groups C and D) was performed with 50 cysts of T. gondii (ME-49 strain). Mice from groups B and D were treated with 5 μmol kg-1 of (PhSe)2. Liver tissue from infected mice showed less severe inflammation, elevated ATP/ADO ratio, elevated NTPDase, 5'nucleotidase, and ADA activities compared to the uninfected group (Group A; P < 0.05). However, infected and treated mice showed decreased ATP levels and elevated ADO levels, as well as higher NTPDase and 5'nucleotidase activities and decreased ADA activity in the hepatic tissue compared to the infected group (P < 0.05). Moreover, the (PhSe)2 treatment of infected mice reduced the hepatic inflammation and showed an immunomodulatory effect on ectonucleotidases of hepatic lymphocytes, which it returned to basal levels. Therefore, chronic infection by T. gondii induces hepatic inflammation in mice, and it is possible that purine levels and nucleotidase activities in hepatic tissue are related to the pathogenesis of the infection in this tissue. The treatment with (PhSe)2 was able to reverse the hepatic inflammation in mice chronically infected, possibly due to the modulation of purinergic enzymes that produce an anti-inflammatory profile through the purinergic system in the liver tissue.

Characterization of ectonucleoside triphosphate diphosphohydrolase (E-NTPDase; EC 3.6.1.5) activity in mouse peritoneal cavity cells. Cell Biochem Funct 2017; 35:358-363. [PMID: 28871607 DOI: 10.1002/cbf.3281] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2017] [Revised: 07/05/2017] [Accepted: 07/05/2017] [Indexed: 12/20/2022]
Abstract
This study aimed to characterize the activity of ectonucleoside triphosphate diphosphohydrolase (E-NTPDase; EC 3.6.1.5) in peritoneal cavity cells from BALB/c mice. E-NTPDase was activated in the presence of both calcium (1.5mM) and magnesium (1.5mM) ions. However, the activity was higher in the presence of Ca2+ . A pH of 8.5 and temperature of 37°C were the optimum conditions for catalysis. The apparent Km values were 0.51mM and 0.66mM for the hydrolysis of adenosine triphosphate (ATP) and adenosine diphosphate (ADP), respectively. The Vmax values were 136.4 and 120.8 nmol Pi/min/mg of protein for ATPase and ADPase activity, respectively. Nucleotide hydrolysis was inhibited in the presence of sodium azide (20mM, ATP: P < .05; ADP: P < .001), sodium fluoride (20mM; ATP and ADP: P < .001), and suramin (0.3mM; ATP: P < .01; ADP: P < .05), which is a known profile for NTPDase inhibition. Although all of the diphosphate and triphosphate nucleotides that were tested were hydrolyzed, enzyme activity was increased when adenine nucleotides were used as substrates. Finally, we stress that knowledge of the E-NTPDase catalytic biochemical properties in mouse peritoneal cavity cells is indispensable for properly determining its activity, as well as to fully understand the immune response profile in both healthy and sick cells.
