Abstract
Nitrogen-containing bisphosphonates, such as alendronate, have been widely used to treat osteoporosis because they may target multiple signals in the mevalonate cascade. The present study evaluated the therapeutic effects of alendronate on experimental autoimmune encephalomyelitis (EAE), which is a prototypical autoimmune disease model. EAE was induced in C57BL/6 mice by immunization with myelin oligodendrocyte glycoprotein (MOG)35-55 peptide. The mice were checked daily for clinical symptoms, such as paralysis, and the levels of inflammatory cytokines were analyzed using ELISA, western blot analyses, and immunohistochemistry. The daily oral administration of alendronate to EAE-induced mice significantly reduced the severity of paralysis and lowered T cell proliferation. Additionally, histopathological examinations confirmed that alendronate mitigated inflammation in the spinal cord after EAE induction, suppressed the infiltration of CD68-positive inflammatory cells, and reduced the production of various pro-inflammatory cytokines, including interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ, as well as inducible nitric oxide synthase (iNOS). Furthermore, the alendronate-treated group exhibited a decrease in the number of iNOS-positive inflammatory cells compared to the vehicle-treated group. Taken together, the present results suggest that alendronate alleviated neuro-inflammation in the spinal cords of EAE-induced mice, which is an animal model of multiple sclerosis, possibly by inhibiting the downstream effects of the mevalonate cascade.

Rana R, Sharma R, Kumar A. Repurposing of Existing Statin Drugs for Treatment of Microbial Infections: How Much Promising? Infect Disord Drug Targets 2020; 19:224-237. [PMID: 30081793 DOI: 10.2174/1871526518666180806123230] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2017] [Revised: 05/20/2018] [Accepted: 07/23/2018] [Indexed: 01/27/2023]
Abstract
Today's microbial infections' resistance to approved drugs, the emergence of new infectious diseases and lack of vaccines, create a huge threat to human health. Thus, there is an urgent need to create novel antimicrobial agents, but the high cost and prolonged timeline of novel drug discovery and development is the major barrier to make new drugs. Therefore, there is a need for specific cost effective approaches in order to identify new drugs for the treatment of various microbial infections. Drug repurposition is an alternative technique to find existing clinically approved drugs for other indications. This approach may enhance the portfolio of Pharmaceutical companies by reducing the time and money required for the development of new chemical entity. In literature, various studies have reported some encouraging results regarding the antimicrobial use of existing statin drugs. Further, some clinical studies have also shown the protective effect of statin drugs in reduction of the morbidity and mortality due to many infectious diseases but complete understanding is still lacking. Thus, there is a need for better understanding of the use of statin drugs, especially in the context of antimicrobial effects. In this review, we try to summarize the use of statin drugs in various infectious diseases and their proposed antimicrobial mechanism of action. Further, current challenges and future perspectives of repurposition of statin drugs as antimicrobial agents have also been discussed.

Abstract
Numerous experimental studies demonstrate that the Ras homolog family of guanosine triphosphate hydrolases (Rho GTPases) Ras homolog family member A (RhoA), Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division cycle 42 (Cdc42) are important regulators in somatosensory neurons, where they elicit changes in the cellular cytoskeleton and are involved in diverse biological processes during development, differentiation, survival and regeneration. This review summarizes the status of research regarding the expression and the role of the Rho GTPases in peripheral sensory neurons and how these small proteins are involved in development and outgrowth of sensory neurons, as well as in neuronal regeneration after injury, inflammation and pain perception. In sensory neurons, Rho GTPases are activated by various extracellular signals through membrane receptors and elicit their action through a wide range of downstream effectors, such as Rho-associated protein kinase (ROCK), phosphoinositide 3-kinase (PI3K) or mixed-lineage kinase (MLK). While RhoA is implicated in the assembly of stress fibres and focal adhesions and inhibits neuronal outgrowth through growth cone collapse, Rac1 and Cdc42 promote neuronal development, differentiation and neuroregeneration. The functions of Rho GTPases are critically important in the peripheral somatosensory system; however, their signalling interconnections and partially antagonistic actions are not yet fully understood.

Abstract
The mevalonate pathway is essential for the synthesis of isoprenoids and cholesterol. Adipose tissue is known as a major site for cholesterol storage; however, the role of the local mevalonate pathway and its synthesized isoprenoids remains unclear. In this study, adipose-specific mevalonate pathway-disrupted (aKO) mice were generated through knockout of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase (HMGCR). aKO mice showed serious lipodystrophy accompanied with glucose and lipid metabolic disorders and hepatomegaly. These metabolic variations in aKO mice were dramatically reversed after fat transplantation. In addition, HMGCR-disrupted adipocytes exhibited loss of lipid accumulation and an increase of cell death, which were ameliorated by the supplementation of mevalonate and geranylgeranyl pyrophosphate but not farnesyl pyrophosphate and squalene. Finally, we found that apoptosis may be involved in adipocyte death induced by HMGCR down-regulation. Our findings indicate that the mevalonate pathway is essential for adipocytes and further suggest that this pathway is an important regulator of adipocyte turnover.

Abstract
BACKGROUND AND PURPOSE The purpose of this randomized, placebo-controlled, double-blind study was to investigate the preventive effect of topical administration of atorvastatin (ATV) on the acute radiation-induced skin toxicity in patients with breast cancer. PATIENTS AND METHODS Seventy breast cancer patients were randomly assigned to use topical ATV 1% or placebo gels during radiotherapy twice daily. Radiation-induced dermatitis was classified according to the radiation therapy oncology group (RTOG) criteria, as well as pain and itching were scored according to VAS (visual analogue scale) for 6 weeks of treatment. RESULTS Topical administration of ATV gel during radiotherapy reduced significantly radiation-induced breast swelling, itching, and pain in breast cancer patients by factors of 1.8, 1.7, and 1.5, respectively. ATV reduced the redness caused by radiotherapy in patients as compared with placebo; however, this difference was statistically not significant. CONCLUSION ATV was able to reduce significantly itching, breast edema, and pain in patients during radiotherapy.

Abstract
Background Recent studies have demonstrated that statins have anti-inflammatory and immunomodulatory properties, which could be considered beneficial in kidney transplantations. This study assesses the anti-inflammatory effect of atorvastatin on the kidney grafts of living donor transplants. Material/Methods In a randomized clinical trial, kidney donors were divided into 2 groups. The study group constituted 24 donors who received 40 mg atorvastatin, and 24 donors who received a placebo control, 4 weeks prior to transplantation. Serum C-reactive protein (CRP) levels were measured before and after atorvastatin administration. CRP and renal function of kidney recipients were measured at baseline and 1, 6, and 24 hours after transplantation. Results After 4 weeks of treatment, the CRP level was 5.62±3.82 mg/dL in the control group and 3.27±0.62 mg/dL in the study group (P=0.007). Upon reperfusion, CRP levels in recipients at 1 hour were, 5.8±3.9 and 3.8±1.0 mg/dL, respectively (P=0.04). Twenty-four hours after the kidney transplantations, serum creatinine levels were 2.5±1.5 mg/dL in the study group and 3.7±2.4 mg/dL in the control group (P=0.04). Conclusions Our study suggests that the use of atorvastatin prior to allograft procurement of kidney transplant, reduces the acute kidney inflammatory burden profile, and promotes an improved kidney function recovery following transplantation.

Abstract
BACKGROUND Atorvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitor widely used in treatment of hypercholesterolemia and prevention of coronary heart disease and has various pleiotropic effects. In this study, the efficacy of atorvastatin emulgel (2 %) in reducing postoperative pain at rest, pain during defecation and analgesic requirement after open hemorrhoidectomy was investigated. METHODS A total of 66 patients with third- and fourth-degree hemorrhoids undergoing open hemorrhoidectomy were included in this prospective, double-blind, randomized controlled trial. The patients were randomly assigned to either atorvastatin emulgel or placebo immediately after surgery and then every 12 h for 14 days. The primary outcomes were intensity of pain at rest and during defecation, measured with a visual analog scale, and the analgesic requirement, measured by amount of pethidine and acetaminophen consumption, and percent of wound healing. RESULTS There was no significant difference in the average postoperative pain scores in the first 48 h (P 12h = 1, P 24h = 0.128 and P 48h = 0.079) after the surgery between the two groups, but at the week 1 the pain scores during defecation were considerably lower in the atorvastatin group than in placebo group (P = 0.004), which also was the same at the week 2 (P = 0.03). There was no significant difference in the average pethidine and acetaminophen (mg) administration at 12 h and 24 h between the two groups after surgery. Regarding the data about wound healing, at the week two the healing was much better in the treatment group than it was in control group and the difference was statistically significant (P = 0.04). CONCLUSIONS Compared with placebo, atorvastatin emulgel reduced postoperative pain at rest and on defecation and could improve the healing process after open hemorrhoidectomy.

Abstract
INTRODUCTION Atorvastatin is a statin group medicine that reduces the level of serum cholesterol; thus it is used to treat hypercholesterolaemia. Independent of the cholesterol-lowering property of statins they also have anti-inflammatory and immunomodulating effects. This study aimed to investigate the effect of atorvastatin on histological changes in the lungs in a murine model of chronic asthma. MATERIALS AND METHODS Twenty-eight BALB/c mice in Group I, II, III and IV were divided into four groups. All the mice except the control group (Group I) were sensitised with ovalbumin. Intraperitoneal injection with saline, atorvastatin (10mg/kg), dexametazon (1mg/kg) was administered to Group II, Group III, and Group IV respectively for five consecutive days. Mice were sacrificed 24h after the last drug administration. All the histological properties of lung tissue samples from all groups were evaluated with light and electron microscopy. In addition, IL-4 and IL-5 levels of the lung tissue were measured. RESULTS When Group II and Group III (atorvastatin) were compared, thicknesses of basement membrane and subepithelial smooth muscle layer, height of epithelium, number of mast and goblet cells were significantly lower in Group III. In comparing Group III (atorvastatin) and Group IV (dexamethasone), all the improvements in histological parameters were similar. In addition, the IL-4 and IL-5 levels of the lung tissue were significantly lower in atorvastatin group (Group III) compared to placebo-treated group. CONCLUSION Atorvastatin had a beneficial effect on histological changes in a chronic murine model of asthma.

Abstract
Statins have immunomodulatory effects. Hence, they could be advantageous for different reasons. First, statins can serve as adjunct therapy in autoimmune diseases. Second, they may play a role in the prevention of accelerated atherosclerosis in the same population. In this review, we discuss the mechanisms of immune regulation by statins and review the literature for their benefit in many autoimmune diseases. In these studies, statins lead to an improvement in the disease activity scores in rheumatoid arthritis patients; a reduction in prothrombotic factors in anti-phospholipid syndrome patients; changes in vasculature, proteinuria, and cardiac events in systemic lupus erythematosus patients; changes in vasculature and proteinuria in patients with vasculitis; disease activity scores in ankylosing spondylitis; and finally vascular changes in patients with systemic sclerosis. Hence, these studies suggest that statins could be used as adjuncts to standard therapy due to their anti-inflammatory, immunomodulatory, and anti-thrombogenic effects. More evidence-based research is required to determine whether statin regimens will become the standard of care in patients with autoimmune diseases.

Abstract
The pathogenesis of accelerated cardiovascular damage commonly characterizing patients affected by systemic chronic inflammatory and autoimmune rheumatic disorders is quite complex and still not fully clarified. However, it is well accepted that a strong relationship between multiple factors, including both traditional cardiovascular risk factors and disease-related inflammatory and autoimmune mechanisms, may in part explain the precocious atherosclerotic vessel damage and the increased incidence of cardiovascular events. Nevertheless, although several recent studies focused their attention on the investigation of these complex mechanisms, data regarding possible preventive strategies aimed to reduce long-term cardiovascular risk in these subjects are still lacking and not conclusive. In this setting, the early introduction of evidence-based preventive measures for the correct management of patients with systemic autoimmune disorders would be of extreme importance to reduce subclinical atherosclerosis incidence and possible major cardiovascular events.

Abstract
Statins, inhibitors of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, are known not only as cholesterol-lowering agents but also as anti-inflammatory mediators. However, their regulatory effect on intestinal mucosal immunity remains unclear. The present study examined the possible direct effects of statin on intestinal intraepithelial lymphocytes (IELs), the front line cells of the intestinal mucosal immune system. Murine IELs were isolated from the small intestines of C57BL/6 mice. IELs activated with anti-CD3/CD28 monoclonal antibodies produced interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-2, and IL-4 in significant numbers; however, they did not produce IL-5. Both simvastatin and lovastatin suppressed IEL production of IFN-γ, TNF-α, IL-2, and IL-4 in a dose-dependent manner, whereas 48-h treatment with high concentrations (5 × 10(-5)M) of simvastatin and lovastatin did not affect the number of IELs. The suppressive effect of the simvastatin was significantly restored by the addition of mevalonate, farnesyl pyrophosphate ammonium salt, and geranylgeranyl pyrophosphate ammonium salt, which are downstream metabolites of HMG-CoA. These findings suggest that statins have direct suppressive effects on the production of T helper 1-cytokines and IL-4 in IELs; these effects are associated with inhibition of the mevalonate pathway to some extent.

Abstract
BACKGROUND Asthma is characterized by airway hyperresponsiveness and remodeling. Pravastatin and atorvastatin are used clinically as cholesterol-lowering agents but also exhibit anti-inflammatory and immunomodulating properties. OBJECTIVE To investigate the therapeutic effect of oral statins on airway hyperresponsiveness and allergic reaction. METHODS BALB/c mice received intraperitoneal sensitization and aerosol inhalation with ovalbumin consequently. One week after ovalbumin aerosol challenge, pravastatin, atorvastatin, or phosphate-buffered saline were given by intragastric gavage daily for 2 weeks. Airway hyperresponsiveness, serum allergen specific antibody levels, cytokine production by splenocytes, and bronchoalveolar lavage fluid were examined. RESULTS Both pravastatin and atorvastatin effectively reduced airway hyperresponsiveness. Pravastatin effectively suppressed both T(H)1- and T(H)2-mediated antibody responses, reducing serum specific IgE, IgG, IgG1, and IgG2a levels. Pravastatin also effectively reduced interleukin (IL) 4, IL-5, and interferon γ production but significantly enhanced IL-10 levels in splenocytes and BALF. Similarly, atorvastatin effectively attenuated production of specific IgE, IgG1, and IgG2a antibodies. It also significantly attenuated IL-4, interferon γ, and increased IL-10 concentration in bronchoalveolar lavage fluid and splenocytes. CONCLUSION Oral administration of pravastatin or atorvastatin not only was able to inhibit T(H)1 inflammatory responses but also had therapeutic effects on airway hyperresponsiveness and T(H)2 allergic responses. These results seem to suggest that these drugs have potential as a nonimmunosuppressive therapy for asthma and allergic diseases.
