Abstract
The objective of our study was to assess the effect of human umbilical cord blood (HUCB) mesenchymal stem cells (MSCs) transplantation on schistosomal hepatic fibrosis in mice. The study animals were divided into three groups. Group I is a control group, where the mice were infected with Schistosoma mansoni cercariae and remained untreated. The mice of the other two groups were infected and treated with either praziquantel (Group II) or HUCB-MSCs (Group III). Liver function tests, as well as histopathological evaluation of liver fibrosis using hematoxylin and eosin and Masson's trichrome stains, were performed. Additionally, an immunohistochemical study was carried out using anti-glial fibrillary acidic protein (GFAP) in hepatic stellate cells. Compared to the control group, the treated (praziquantel and MSCs) groups showed a substantial improvement, with a significant difference regarding the histopathological evaluation of liver fibrosis in the MSCs-treated group. In conclusion, MSCs could be a promising and efficient cell therapy for liver fibrosis.

[PMID: 35777451 DOI: 10.1016/j.exppara.2022.108317] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 06/13/2022] [Accepted: 06/24/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Many studies have reported the immunomodulatory effect of helminths to avoid the lethal immunopathology. During schistosomiasis, the immune response is orchestrated by toll-like receptors (TLRs). Modulating TLRs can alter the function of antigen presentation cells with the shift of the host's Th1 response to a dominant regulatory Th2 response. The objective of our study was to clarify which TLRs are related to the immune response of chronic Schistosoma infection. METHODS The study animals were divided into two groups; group I: uninfected mice; control group and group II: Schistosoma mansoni infected mice. mRNA expression of TLR2, 3, 4, 7, and 9 in different organs (liver, large intestine, and spleen) were assessed on day 90 post-infection. RESULTS TLR gene expression has changed depending on the tissue studied as the mRNA level of TLR2, TLR7, and TLR9 were significantly upregulated in all examined organs while TLR3 expression showed only significant upregulation in the liver of infected mice. On the other hand, TLR4 expression was significantly upregulated in the liver while significantly downregulated in the large intestine. CONCLUSION This study provides a better understanding of TLRs profile in different organs against S. mansoni parasites during the chronic phase of infection.

Abstract
BACKGROUND Schistosomiasis is an acute and chronic disease of the genus Schistosoma triggered by blood flukes. Schistosomiasis is a disease occurring in, or endemic to, tropical and subtropical regions. A new concept was implemented to deal with schistosomiasis from natural plant sources. Curcumin's common name is Turmeric. Curcumin has proven to be main active component in Curcuma longa L. and has a wide range of anti-phrastic effects. Previous studies have shown the role of bone marrow mesenchymal stem cells (BMSCs) therapy in hepatic fibrosis recovery. OBJECTIVE The current study was, therefore, intended to examine therapeutic role of BMSCs and Turmeric in murine schistosomiasis mansoni. ANIMALS Mice were divided into five groups: a negative control group (non-infected non-treated), a positive control group (infected non-treated), a BMSCs treated group; Turmeric treated group, and untreated group. BMSCs derived from male mice were injected intraperitoneally into female mice receiving S. mansoni cercariae through the subcutaneous route. Liver histopathology and immuno-histochemical examinations were evaluated. RESULTS BMSCs intraperitoneal injection resulted in a significant reduction of liver collagen, granuloma size, and significant increase of OV-6 expression in the Schistosomiasis-treated mice group. There was overall improvement in pathological changes of the liver. Unfortunately, group IV showed a mild improvement in the granuloma size and fibrosis compared to corresponding BMSCs treatment group, although with vacuolated liver cells. CONCLUSION AND CLINICAL RELEVANCE BMSCs have a regenerative potential in liver tissue histopathology by decreasing liver fibrosis and granulomas. Turmeric, by contrast, could not be used as an anti-fibrotic, according to the findings.

Abstract
Intravital microscopy allows imaging of biological phenomena within living animals, including host-parasite interactions. This has advanced our understanding of both, the function of lymphoid organs during parasitic infections, and the effect of parasites on such organs to allow their survival. In parasitic research, recent developments in this technique have been crucial for the direct study of host-parasite interactions within organs at depths, speeds and resolution previously difficult to achieve. Lymphoid organs have gained more attention as we start to understand their function during parasitic infections and the effect of parasites on them. In this review, we summarise technical and biological findings achieved by intravital microscopy with respect to the interaction of various parasites with host lymphoid organs, namely the bone marrow, thymus, lymph nodes, spleen and the mucosa-associated lymphoid tissue, and present a view into possible future applications.

Abstract
Some reports have shown that mesenchymal stem cells (MSCs) therapy could ameliorate chemically-induced hepatic fibrosis. This research assesses the therapeutic action of bone marrow mesenchymal stem cells (BM-MSCs) on chronic diseased liver in Schistosoma mansoni infected mice. All infected female mice divided into three groups, one group (15 mice) treated with oral praziquantel (PZQ), second group (15 mice) received intravenous injection of BM-MSCs and third group (15 mice) treated with both MSCs + PZQ. Two control groups (15 mice each) subdivided into one infected and second healthy one. BM-MSCs were obtained from bones of both femur and tibia of male mice (30 mice), then cultured and characterized morphologically by detection of CD105 by flow cytometer. Liver tissues for all groups were examined histopathologically. Measuring of the collagen 1 gene expression was done by real-time PCR and immunohistochemical study to detect stem cells differentiation for detection of MSCs engraftments in liver tissue. MSCs treatment caused marked improvement and regression of fibrosis, and prevents deposition of collagen and reduced the expression of collagen 1 gene in infected mice on their liver tissues, especially when used with PZQ in mice treatment. It can be concluded that, MSCs is a good therapeutic method for liver fibrosis caused by S. mansoni infection.

Abstract
Background and Objectives Bone marrow derived mesenchymal stem cells (BM-MSCs) have been proposed as effective treatment of many diseases owing to their unique ability to differentiate into other cell types in vivo. Schistosoma mansoni (S. mansoni) infection is characterized by hepatic granuloma formation around schistosome eggs at acute stage of infection, followed by hepatic fibrosis at chronic and advanced stages. Whether BM-MSCs have an ameliorative effect on hepatic tissue injury caused by S. mansoni infection or not, was inspected in the current study. Materials and Results Female Swiss Albino mice were divided into a control group and an experimental group. Half of control animals served as donors for bone marrow stem cells, and the other half was used to collect liver samples. Experimental group was injected with circariae of S. mansoni, and then subdivided into three subgroups; Subgroup B1, sacrificed after eight weeks of infection without treatment, subgroup B2, received BM-MSCs at the eighth week and sacrificed four weeks later, and subgroup B3, was untreated till the twelfth week of infection. Histological examination of liver samples showed the formation of granulomas and liver fibrosis which were extensive in subgroup B3. However, treated subgroup illustrated improvement of liver histology, signs of hepatocytes regeneration, and possible contribution of oval cell in the process of hepatic and biliary regeneration. Conclusion BM-MSCs decreased liver fibrosis and contributed to an increase in oval cells, generation of new hepatocytes and/or to the improvement of resident hepatocytes in S. mansoni infected mice.

Abstract
Cell-based therapy is emerging as a promising therapeutic approach for a wide range of liver diseases. This study aimed to investigate the regenerative and antifibrotic therapeutic potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) in an early and late experimental hepatic schistosomiasis model. BM-MSCs were isolated from 6-wk-old BALB/c donor male mice, then grown and propagated in culture until cell count was 5-8 × 10(6)/ml. MSCs were then separated and injected into Schistosoma mansoni -infected female BALB/c mice on their 6, 10, 14, and 18 wk post-infection. Mice were sacrificed on the fourth and eighth week after BM-MSCs transplantation in each group. Homing of BM-MSCs was confirmed by PCR detection of male Y-chromosome gene (sry) in the liver tissue of the recipient female mice. The regenerative and antifibrotic potential of BM-MSCs was assessed by histopathological examination, morphometric analysis, electron microscopy, and liver function tests. Schistosoma-infected mice, which were treated with BM-MSCs, showed a decrease in the granuloma size, percentage and density of the fibrotic area, formation of new hepatocytes, and improvement of the liver function tests. Immunohistochemical examination of alpha-smooth muscle actin revealed a significant decrease in the immunoreactive hepatic stellate cells in mice treated with MSCs. Early granulomas (acute infection) showed better response to MSC injection than did later granulomas (chronic infection). Dosing and timing of MSCs transplantation should undergo more investigations in long-term experiments before application to the clinical field. This study is the first to assess and compare the effect of MSCs treatment on early and late granulomas.

Abstract
The technique of stem cells or hepatocytes transplantation has recently improved in order to bridge the time before whole-organ liver transplantation. In the present study, unfractionated bone marrow stem cells (BMSCs) were harvested from the tibial and femoral marrow compartments of male mice, which were cultured in Dulbecco's modified Eagle's medium (DMEM) with and without hepatocyte growth factor (HGF), and then transplanted into Schistosoma mansoni-infected female mice on their 8th week post-infection. Mice were sacrificed monthly until the third month of bone marrow transplantation, serum was collected, and albumin concentration, ALT, AST, and alkaline phosphatase (ALP) activities were assayed. On the other hand, immunohistopathological and immunohistochemical changes of granuloma size and number, collagen content, and cells expressing OV-6 were detected for identification of liver fibrosis. BMSCs were shown to differentiate into hepatocyte-like cells. Serum ALT, AST, and ALP were markedly reduced in the group of mice treated with BMSCs than in the untreated control group. Also, granuloma showed a marked decrease in size and number as compared to the BMSCs untreated group. Collagen content showed marked decrease after the third month of treatment with BMSCs. On the other hand, the expression of OV-6 increased detecting the presence of newly formed hepatocytes after BMSCs treatment. BMSCs with or without HGF infusion significantly enhanced hepatic regeneration in S. mansoni-induced fibrotic liver model and have pathologic and immunohistopathologic therapeutic effects. Also, this new therapeutic trend could generate new hepatocytes to improve the overall liver functions.

Abstract
Mesenchymal stem cells (MSCs) have gained popularity for their potential as seed cells to treat various human diseases, including pathogenic infections. Schistosoma japonicum (S. japonicum) infection is characterized by formation of parasite egg granulomas and host liver fibrosis. MSCs have been proposed as useful treatments of S. japonicum infection, but the efficacy and underlying mechanisms remain unknown. Herein, we report that MSCs were able to ameliorate S. japonicum-induced liver injury in vivo and this effect was enhanced by combining MSCs with conventional drug praziquantel (PZQ). Kunming strains of mice were infected with S. japonicum and treated with vehicle, MSCs, PZQ or PZQ + MSCs. MSC treatment not only prolonged the survival time of infected mice but reduced egg granuloma diameter and decreased the concentrations of serum transforming growth factor-β1 and hyaluronic acid. MSC treatment also inhibited collagen deposition and reduced the expression of collagen type 3, α-smooth muscle actin and vimentin in infected mouse liver tissues. Collectively, our findings suggest that MSC treatment represents a novel therapeutic approach for S. japonicum-induced liver injury and fibrosis.
