Exp Parasitol 2024; 262:108775. [PMID: 38735518 DOI: 10.1016/j.exppara.2024.108775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/30/2024] [Accepted: 05/10/2024] [Indexed: 05/14/2024]
Abstract
The limited activity of the traditional medications against T. spiralis encysted larvae handicaps complete cure of trichinellosis till now due to decreased permeability and absorption through tissues. MOX is listed worldwide for prevention and treatment of several internal and external nematodes. Consequently, the aim of this work was to investigate the effect of moxidectin versus ivermectin on experimental acute and chronic trichinellosis and to illuminate the potential mechanisms of their effects. 105 Mice were divided into four groups; Group I: Uninfected healthy control; Group II: Infected untreated control; Group III: Infected and treated with IVM and Group IV: Infected and treated with MOX. The groups (II, III and IV) were later subdivided equally into three subgroups (a, b, and c) according to the stage of treatment. Parasitological counting of adults and larvae besides immune-histopathological examination of intestines and muscles were done. Results exhibited that both IVM and MOX succeeded in reducing adults and larvae counts with higher potential of MOX in both intestinal and muscle phase. The preeminence of MOX was indicated by decreased inflammation, a significant reduction in the microvascular density (CD31 immunostaining) as well as a reduction in the percentage of fibroblast activation protein (FAP) immunostaining in muscle tissues. Accordingly, the current work recommends moxidectin as an innovative treatment for trichinellosis.

Biochem Pharmacol 2024; 226:116337. [PMID: 38844265 DOI: 10.1016/j.bcp.2024.116337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 05/31/2024] [Accepted: 06/03/2024] [Indexed: 06/10/2024]
Abstract
Spinal cystic echinococcosis (CE) is a rare but malignant zoonosis that can cause disability or even death in more than half of patients. Due to the complex pathological features, it is not curable by conventional drugs and surgery, so new therapeutic targets urgently need to be discovered. In this study, we clarify the occurrence of the phenomenon of spinal encapsulation angiogenesis and explore its underlying molecular mechanisms. A co-culture system was established by protoscoleces (PSCs) with human umbilical vein endothelial cells (HUVECs) which showed a high expression level of Nrf2. A short hairpin RNA (shRNA) and Sulforaphane (SFN) affecting the expression of Nrf2 were used to treat HUVECs. The results showed that Nrf2 could promote the tube formation of HUVECs. Nrf2 also exerts a protective effect against HUVECs, which is achieved by promoting NQO1 expression to stabilize ROS levels. Furthermore, autophagy activation significantly promotes angiogenesis in the spinal echinococcosis model (SEM) as a result of Nrf2 regulation of oxidative stress. These results suggest that the ROS/Nrf2/autophagy axis can induce angiogenesis and may be a potential target for the treatment of spinal cystic echinococcosis.

Abstract
The free radical nitric oxide (NO) and Ca2+ are critical regulators of skeletal muscle exercise performance and fatigue. The major source of NO in skeletal muscle cells is the neuronal form of the enzyme Nitric oxide synthase (nNOS). One of the most peculiar characteristics of the Nurse cell of Trichinella spiralis (T. spiralis) is the complete loss of the contractile capabilities of its derivative striated muscle fiber. The aim of the present study was to clarify the expression of nNOS protein and mRNA in striated muscles during the muscle phase of T. spiralis infection in mice. Muscle tissue samples were collected from mice at days 0, 14, 24, and 35 post infection (d.p.i.). The expression of nNOS was investigated by immunohistochemistry, and the expression levels of mRNA of mouse Nitric oxide synthase 1 (Nos1) by real-time PCR. The presence of nNOS protein was still well observable in the disintegrated sarcoplasm at the early stage of infection. The cytoplasm of the developing and mature Nurse cell showed the absence of this protein. At least at the beginning of the Nurse cell development, Trichinella uses the same repairing process of skeletal muscle cell, induced after any trauma and this corroborates very well our results concerning the nNOS expression on day 14 p.i. At a later stage, however, we could suggest that the down-regulation of nNOS in the Nurse cell of T. spiralis either serves a protective function or is an outcome of the genetic identity of the Nurse cell.

Abstract
Trichinosis spiralis is a global disease with significant economic impact. Albendazole is the current-treatment. Yet, the world-widely emerging antimicrobial resistance necessitates search for therapeutic substitutes. Curcumin is a natural compound with abundant therapeutic benefits. This study aimed to evaluate the potential of crude-curcumin, chitosan and for the first time curcumin-nano-emulsion and curcumin-loaded-chitosan-nanoparticles against Trichinella spiralis adults and larvae in acute and chronic trichinosis models. Trichinosis spiralis was induced in 96 Swiss-albino mice. Infected mice were divided into 2 groups. Group I constituted the acute model, where treatment started 2 h after infection for 5 successive days. Group II constituted the chronic model, where treatment started at the 30th day-post-infection and continued for 10 successive days (Refer to graphical abstract). Each group contained 8 subgroups that were designated Ia-Ih and IIa-IIh and included; a; Untreated-control, b; Albendazole-treated (Alb-treated), c; Crude-curcumin-treated (Cur-treated), d; Curcumin-nanoemulsion-treated (Cur-NE-treated), e; Albendazole and crude-curcumin-treated (Alb-Cur-treated), f; Albendazole and curcumin-nanoemulsion-treated (Alb-Cur-NE-treated), g; Chitosan-nanoparticles-treated (CS-NPs-treated) and h; Curcumin-loaded-chitosan-nanoparticles-treated (Cur-CS-NPs-treated). Additionally, six mice constituted control-uninfected group III. The effects of the used compounds on the parasite tegument, in-vivo parasitic load-worm burden, local pathology and MDA concentration in small intestines of acutely-infected and skeletal muscle of chronically-infected mice were studied. Results showed that albendazole was effective, yet, its combination with Cur-NE showed significant potentiation against adult worms and muscle larvae and alleviated the pathology in both models. Cur-CS-NPs exhibited promising results in both models. Crude-curcumin showed encouraging results especially against muscle larvae on long-term use. Treatments effectively reduced parasite load, local MDA level and CD31 expression with anti-inflammatory effect in intestine and muscle sections.

Abstract
Trichinellosis is one of the global food-borne parasitic diseases that can cause severe tissue damage. The traditionally used drugs for the treatment of trichinellosis have limited efficacy against the encysted larvae in the muscular phase of the disease. Therefore, this study aimed to evaluate the role of atorvastatin and mesenchymal stem cells combined with ivermectin against different phases of Trichinella in experimentally infected mice. A total of 120 male Swiss albino mice were divided into two major groups (n = 60 of each), intestinal and muscular phases. Then, each group was subdivided into 10 subgroups (n = 6); non-infected control, infected non-treated control, infected ivermectin treated, infected atorvastatin treated, infected mesenchymal stem cells treated, infected combined ivermectin and atorvastatin treated, infected combined mesenchymal stem cells and ivermectin treated, infected combined mesenchymal stem cells and atorvastatin treated, infected combined mesenchymal stem cells and a full dose of (ivermectin and atorvastatin) treated, and infected combined mesenchymal stem cells and half dose of (ivermectin and atorvastatin) treated. Mice were sacrificed at days 5 and 35 post-infection for the intestinal and muscular phases, respectively. The assessment was performed through many parameters, including counting the adult intestinal worms and muscular encysted larvae, besides histopathological examination of the underlying tissues. Moreover, a biochemical assay for the inflammatory and oxidative stress marker levels was conducted. In addition, levels of immunohistochemical CD31 and VEGF gene expression as markers of angiogenesis during the muscular phase were investigated. The combined mesenchymal stem cells and atorvastatin added to ivermectin showed the highest significant reduction in adult worms and encysted larvae counts, the most noticeable improvement of the histopathological changes, the most potent anti-inflammatory (lowest level of IL-17) and anti-angiogenic (lowest expression of CD31 and VEGF) activities, and also revealed the highly effective one to relieve the oxidative stress (lowest level of SOD, GSH, and lipid peroxidase enzymes). These observed outcomes indicate that adding mesenchymal stem cells and atorvastatin to ivermectin synergistically potentiates its therapeutic efficacy and provides a promising candidate against trichinellosis.

Abstract
Parasitic diseases still pose a serious threat to human and animal health, particularly for millions of people and their livelihoods in low-income countries. Therefore, research into the development of effective antiparasitic drugs remains a priority. Ivermectin, a sixteen-membered macrocyclic lactone, exhibits a broad spectrum of antiparasitic activities, which, combined with its low toxicity, has allowed the drug to be widely used in the treatment of parasitic diseases affecting humans and animals. In addition to its licensed use against river blindness and strongyloidiasis in humans, and against roundworm and arthropod infestations in animals, ivermectin is also used "off-label" to treat many other worm-related parasitic diseases, particularly in domestic animals. In addition, several experimental studies indicate that ivermectin displays also potent activity against viruses, bacteria, protozoans, trematodes, and insects. This review article summarizes the last 40 years of research on the antiparasitic effects of ivermectin, and the use of the drug in the treatment of parasitic diseases in humans and animals.
