Abstract
Drug-eluting stents (DES) and dual antiplatelet regimens have significantly improved the clinical management of ischemic heart disease; however, the drugs loaded with DES in clinical practice are mostly paclitaxel or rapamycin derivatives, which target symptoms of post implantation proliferation and inflammation, leading to delayed re-endothelialization and neo-atherosclerosis. Along with the treatments already in place, there is a need for novel strategies to lessen the negative clinical outcomes of DES delays as well as a need for greater understanding of their pathobiological mechanisms. This review concentrates on the function of cathepsins (Cats) in the inflammatory response and granulation tissue formation that follow Cat-induced damage to the vasculature scaffold, as well as the functions of Cats in intimal hyperplasia, which is characterized by the migration and proliferation of smooth muscle cells, and endothelial denudation, re-endothelialization, and/or neo-endothelialization. Additionally, Cats can alter essential neointima formation and immune response inside scaffolds, and if Cats are properly controlled in vivo, they may improve scaffold biocompatibility. This unique profile of functions could lead to an original concept for a cathepsin-based coronary intervention treatment as an adjunct to stent placement.

Vet Dermatol 2021; 32:638-e170. [PMID: 33890342 DOI: 10.1111/vde.12946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 11/13/2020] [Accepted: 12/05/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Feline atopic syndrome (FAS) is a common disease. Single intradermal injections of heat-killed actinomycetales have shown beneficial effects in canine allergies. HYPOTHESIS/OBJECTIVE To evaluate the clinical effects of heat-killed actinomycetales [Gordonia bronchialis (GB) and Rodococcus coprophilus (RC)], alone or in combination, in FAS. METHODS AND MATERIALS Privately owned cats with a diagnosis of FAS were assigned randomly in three treatment groups (GB, RC and GB/RC combination) or placebo. Five intradermal injections were performed over a one year period. At each visit [Day (D)0, D20, D40, D60, D90, D180 and D365], clinical signs, global owner assessment score, use of rescue medications, clinical adverse effects, skin hydration and cutaneous pH were assessed. RESULTS Seventeen cats were enrolled. When compared to the placebo group and improvement in treatment GB was sustained from D90. When compared with D0 significant improvement in the GB group was seen from D60. Over one year, a complete remission of the clinical signs was seen in 30-67% of cats in the treatment groups. A reduction in the pruritus score was seen for RC after 365 days of treatment (P = 0.04). Differences in the other variables were not seen. CONCLUSIONS AND CLINICAL IMPORTANCE The use of multiple intradermal injections of heat-killed GB shows promise as effective and well-tolerated treatment for FAS. Because of the low cost and the lack of adverse effects, GB could be a beneficial treatment option for FAS. A larger study is needed to confirm these data and to evaluate the immunological changes occurring in the treated cats.

Abstract
Background: This study evaluated the possible protective effects of Gordonia bronchialis (Gb) on oxidative stress and some subsequent alterations on testis from rats undergoing an experimentally induced type 1 diabetes. Methods: A total of 40 male rats were randomly divided into four groups of ten. Diabetes was induced by injection of 55 mg/kg streptozotocin in 30 rats. Oral administration of Gb at dose of 105 (low dose) and 107 (high dose) CFU/rat was performed in two groups continuously for 14 days. The third and fourth groups received normal saline as the diabetic and healthy control groups, respectively. The blood and testicular tissue samples were taken on the 14th and 21st days post treatment for biochemical and histopathological evaluations. Results: Significant differences were found in blood glucose level, insulin, IL-6 and TNF-α values together with catalase and superoxide dismutase activities and malondialdehyde level in the diabetic group in comparison with healthy and Gb recipient groups. Moreover, the histopathological lesions observed in the diabetic rats mainly included basement membrane thickening, decreased number of Sertoli cells, and severe reduction of spermatogenesis markedly attenuated in Gb-treated rats. Conclusion: Taken together, it seems that oral administration of Gb could ameliorate testicular damage associated with some related parameters in the diabetic animal model.

Abstract
The immunomodulatory power of heat-killed Gordonia bronchialis was studied on gut epithelial cells activated with pro-inflammatory stimuli (flagellin, TNF-α or IL-1β). Light emission of luciferase-transfected epithelial cells and mRNA expression of IL-1β, TNF-α, IL-6, CCL20, IL-8 and MCP-1 were measured. NF-κB activation was assessed by immunofluorescence and immunoblotting, and induction of reactive oxygen species (ROS) was evaluated. In vivo inhibitory properties of G. bronchialis were studied with ligated intestinal loop assay and in a mouse model of food allergy. G. bronchialis promoted the down-regulation of the expression of CCL20 and IL-1β on activated epithelial cells in a dose-dependent manner. A concomitant blocking of nuclear p65 translocation with increased production of ROS was found. In vivo experiments confirmed the inhibition of CCL20 expression and the suppression of IgE sensitization and hypersensitivity symptoms in the food allergy mouse model. In conclusion, heat-killed G. bronchialis inhibited the activation of NF-κB pathway in human epithelial cells, and suppressed the expression of CCL20. These results indicate that G. bronchialis may be used to modulate the initial steps of innate immune activation, which further suppress the allergic sensitization. This approach may be exploited as a therapy for intestinal inflammation.

Abstract
AIMS To determine whether immunotherapy with heat-killed, selected Actinomycetales species could influence the progression of spontaneous Type 2 diabetes mellitus and obesity in a rat model. MATERIALS & METHODS Preparations of either Gordonia bronchialis, Tsukamurella inchonensis or a saline placebo were given by three subcutaneous injections, 30 days apart, starting when rats were aged 120 days, just before development of Type 2 diabetes mellitus, and at day 440, when the disease was well established. Bodyweight, blood sugar, cholesterol, triglycerides and insulin levels were measured to determine the effects and at the end of the experiments, animals were subjected to necropsy. RESULTS The development of Type 2 diabetes mellitus was prevented by both reagents, most effectively by T. inchonensis. In the treatment experiment, the effects of the disease were reduced by both treatments, markedly so by T. inchonensis. In both experiments obesity was reduced in treated animals. The possible mechanisms of action are discussed. CONCLUSION Our findings suggest that Type 2 diabetes mellitus in the studied rats is associated with obesity, and that both diabetes and obesity can be prevented or improved by treatment with Actinomycetales immune modulators.

Abstract
This article describes the first use of heat-killed, borate-buffered preparations of aerobic actinomycetales to immunize pregnant animals in order to determine the effect on their pregnancy and fertility and the survival coefficients of their offspring. Pregnant rats received three injections of Gordonia bronchialis, Rhodococcus coprophylus or physiological saline and a proportion of their offspring were challenged with live Trypanosoma cruzi at the time of weaning. Levels of parasitemia and, in some animals, of the cytokines IFN-γ and IL-10 were measured. The progress of pregnancy, fertility and survival of offspring were unaffected by the maternal immunizations. The offspring of rats immunized with G. bronchialis displayed significantly reduced parasitemias, with increased levels of IFN-γ and reduced levels of IL-10, 4 days after challenge. The offspring of rats immunized with R. coprophylus displayed greater parasitemias than did those of the control group. These unexpected results are discussed and their causation considered.
