Abstract
Pharmacological blockade of α1-adrenoceptor is shown to influence development of experimental autoimmune encephalomyelitis (EAE), an IL-17-producing CD4+TCR+ (Th17) cell-mediated disease mimicking multiple sclerosis. Considering significance of CD4+ cell priming for the clinical outcome of EAE, the study examined α1-adrenoceptor-mediated influence of catecholamines, particularly those derived from draining lymph node (dLN) cells (as catecholamine supply from nerve fibers decreases with the initiation of autoimmune diseases) for CD4+ cell priming. The results confirmed diminishing effect of immunization on nerve fiber-derived noradrenaline supply and showed that antigen presenting and CD4+ cells synthesize catecholamines, while antigen presenting cells and only CD4+CD25+Foxp3+ regulatory T cells (Tregs) express α1-adrenoceptor. The analysis of influence of α1-adrenoceptor antagonist prazosin on the myelin basic protein (MBP)-stimulated CD4+ lymphocytes in dLN cell culture showed their diminished proliferation in the presence of prazosin. This was consistent with prazosin enhancing effect on Treg frequency and their Foxp3 expression in these cultures. The latter was associated with upregulation of TGF-β expression. Additionally, prazosin decreased antigen presenting cell activation and affected their cytokine profile by diminishing the frequency of cells that produce Th17 polarizing cytokines (IL-1β and IL-23) and increasing that of IL-10-producing cells. Consistently, the frequency of all IL-17A+ cells and those co-expressing GM-CSF within CD4+ lymphocytes was decreased in prazosin-supplemented MBP-stimulated dLN cell cultures. Collectively, the results indicated that dLN cell-derived catecholamines may influence EAE development by modulating interactions between distinct subtypes of CD4+ T cells and antigen presenting cells through α1-adrenoceptor and consequently CD4+ T cell priming.

Role of the End-Point Mediators of Sympathoadrenal and Sympathoneural Stress Axes in the Pathogenesis of Experimental Autoimmune Encephalomyelitis and Multiple Sclerosis.

Abstract
The role of stress effector systems in the initiation and progression of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), the most commonly used experimental model of MS, has strongly been suggested. To corroborate this notion, alterations in activity of the sympathoadrenal and sympathoneural axes of sympathoadrenal system (a major communication pathway between the central nervous system and the immune system), mirrored in altered release of their end-point mediators (adrenaline and noradrenaline, respectively), are shown to precede (in MS) and/or occur during development of MS and EAE in response to immune cell activation (in early phase of disease) and disease-related damage of sympathoadrenal system neurons and their projections (in late phase of disease). To add to the complexity, innate immunity cells and T-lymphocytes synthesize noradrenaline that may be implicated in a local autocrine/paracrine self-amplifying feed-forward loop to enhance myeloid-cell synthesis of proinflammatory cytokines and inflammatory injury. Furthermore, experimental manipulations targeting noradrenaline/adrenaline action are shown to influence clinical outcome of EAE, in a disease phase-specific manner. This is partly related to the fact that virtually all types of cells involved in the instigation and progression of autoimmune inflammation and target tissue damage in EAE/MS express functional adrenoceptors. Although catecholamines exert majority of immunomodulatory effects through β2-adrenoceptor, a role for α-adrenoceptors in EAE pathogenesis has also been indicated. In this review, we summarize all aforementioned aspects of immunopathogenetic action of catecholamines in EAE/MS as possibly important for designing new strategies targeting their action to prevent/mitigate autoimmune neuroinflammation and tissue damage.

Noradrenaline through β-adrenoceptor contributes to sexual dimorphism in primary CD4+ T-cell response in DA rat EAE model? Cell Immunol 2018; 336:48-57.

Abstract
Males exhibit stronger sympathetic nervous system (SNS) activity, but weaker primary CD4+ T-cell (auto)immune responses. To test the role of catecholamines, major end-point SNS mediators, in this dimorphism, influence of propranolol (β-adrenoceptor blocker) on mitogen/neuroantigen-stimulated CD4+ T cells from female and male EAE rat draining lymph node (dLN) cell cultures was examined. Male rat dLNs exhibited higher noradrenaline concentration and frequency of β2-adrenoceptor-expressing CD4+ T lymphocytes and antigen presenting cells. Propranolol, irrespective of exogenous noradrenaline presence, more prominently augmented IL-2 production and proliferation of CD4+ lymphocytes in male than female rat dLN cell cultures. In neuroantigen-stimulated dLN cells of both sexes propranolol increased IL-1β and IL-23/p19 expression and IL-17+ CD4+ cell frequency, but enhanced IL-17 production only in male rat CD4+ lymphocytes, thereby abrogating sexual dimorphism in IL-17 concentration observed in propranolol-free cultures. Thus, β-adrenoceptor-mediated signalling may contribute to sex bias in rat IL-17-producing cell secretory capacity.

Abstract
Minicircle DNA (mcDNA) is a kind of enhanced nonviral DNA vector with excellent profiles in biosafety and transgene expression. Herein, we reported a novel amphiphilic polymer comprising polyethylenimine(PEI) modified Poly(β-amino ester) PEI-PBAE(C16) for efficient mcDNA delivery in vivo. The synthesized polymer could condense mcDNA into nanoscaled structure and exhibited efficient gene transfection ability without detectable cytotoxicity. Importantly, when injected into mouse intraperitoneally, these PEI-PBAE(C16) nanocomplexes were able to result in high level of trangene expression which lasted at least 72 h. Overall, these results demonstrated the PEI-PBAE(C16) can mediate effective and safe gene delivery in vivo with clinical application potential.

Abstract
In humans, usual aging, differently from successful aging, is associated with deregulation of proinflammatory/anti-inflammatory cytokine balance. The corresponding data from rat studies are limited. Therefore, we examined (i) cytokine messenger RNA (mRNA) profile of fresh peritoneal cells from 6- (adult), 24- (old), and 31-month-old (long-lived) AO rats and (ii) proinflammatory (IL-1β and IL-6) and anti-inflammatory (IL-10) cytokine, NO, and urea production in their LPS-stimulated cultures. Comparing with adult rats, cells from old ones expressed lower amount of TNF-α and IL-6 mRNAs, but greater amount of IL-1β mRNA. On the other hand, cells from long-lived rats exhibited a dramatic increase in IL-10 mRNA expression followed by diminished TNF-α and IL-6 mRNA expression, and comparable expression of IL-1β mRNA relative to adult rats. Consequently, IL-10/IL-1β mRNA ratio was greater in cells from long-lived rats than in adult and old rats. In LPS-stimulated peritoneal cell cultures (contained ≥95 % macrophages) from old rats, concentration of common proinflammatory cytokines was higher than in those from adult rats. Comparing with adult and old rats, in LPS-stimulated macrophage cultures from long-lived rats, TNF-α and IL-6 concentrations were lower; IL-1β concentration was comparable or greater (in respect to adult rats), whereas that of IL-10 was strikingly higher. Consistently, in macrophage cultures from long-lived rats, NO (iNOS activity marker)/urea (arginase activity marker) ratio was less and not different from that in old and adult rats, respectively. The study suggests that macrophages from long-lived rats, differently from those of old ones, have substantial ability to limit proinflammatory mediator production, which may contribute to their longevity.

Abstract
Catecholamines modulate the production of inflammatory mediators by macrophages in an autocrine/paracrine manner. They also tune β2-adrenoceptor expression. Glucocorticoids influence catecholamine metabolism and adrenoceptor expression in many cell types. We hypothesized that adrenal hormones affect the production of tumour necrosis factor-α (TNF-α) and NO by macrophages by altering the modulatory influence of catecholamines. To prove the hypothesis, peritoneal exudate macrophages from propranolol-treated non-operated and adrenalectomized rats and from corticosterone-supplemented adrenalectomized rats were examined for lipopolysaccharide-stimulated NO and TNF-α production in vitro and for expression of β2-adrenoceptors and major catecholamine-metabolizing enzymes. Glucocorticoid deprivation increased NO production by macrophages, whereas 4 days of propranolol treatment was ineffective in this respect. However, propranolol treatment, via β2-adrenoceptor blockade, increased production of TNF-α by macrophages in both non-operated and adrenalectomized rats (showing dramatically enhanced TNF-α production due to a lack of circulating glucocorticoids) for the same value. The expression of β2-adrenoceptor was increased in peritoneal macrophages that were freshly isolated from non-operated, propranolol-treated and adrenalectomized rats (due to adrenal catecholamine deficiency). Propranolol did not affect macrophage β2-adrenoceptor expression in adrenalectomized rats. Given that propranolol increased the density of macrophage tyrosine hydroxylase expression only in non-operated rats and affected the mRNA expression of monoamine oxidase-A in neither non-operated nor adrenalectomized animals, a significant influence of propranolol on peritoneal exudate cell noradrenaline content was found only in non-operated rats. A lack of circulating adrenal hormones also affected noradrenaline metabolism and content in peritoneal exudate cells including macrophages. Collectively, despite differences in the abundance of macrophage catecholamine-β2-adrenoceptor system components and in the TNF-α response to lipopolysaccharide between adrenalectomized and non-operated rats, propranolol increased TNF-α production by the same amount in macrophages from these two groups of animals.

Abstract
Much evidence has identified a direct anatomical and functional link between the brain and the immune system, with glucocorticoids (GCs), catecholamines (CAs), and neuropeptide Y (NPY) as its end-point mediators. This suggests the important role of these mediators in immune system homeostasis and the pathogenesis of inflammatory autoimmune diseases. However, although it is clear that these mediators can modulate lymphocyte maturation and the activity of distinct immune cell types, their putative role in the pathogenesis of autoimmune disease is not yet completely understood. We have contributed to this field by discovering the influence of CAs and GCs on fine-tuning thymocyte negative selection and, in particular, by pointing to the putative CA-mediated mechanisms underlying this influence. Furthermore, we have shown that CAs are implicated in the regulation of regulatory T-cell development in the thymus. Moreover, our investigations related to macrophage biology emphasize the complex interaction between GCs, CAs and NPY in the modulation of macrophage functions and their putative significance for the pathogenesis of autoimmune inflammatory diseases.

Abstract
Recent studies show that administration of a non-competitive NMDA receptor antagonist, amantadine (AMA), potentiates the action of antidepressant drugs. Since antidepressants may modulate functioning of the immune system and activation of a pro-inflammatory response in depressive disorders is frequently reported, the aim of the present study was to examine whether a combined administration of AMA and the antidepressant, fluoxetine (FLU), to rats subsequently subjected to a forced swimming test (FST) modifies the parameters of macrophage activity, directly related to their immunomodulatory functions, i.e., arginase (ARG) activity and synthesis of nitric oxide (NO). We found that 10 mg/kg AMA and 10 mg/kg FLU, ineffective in FST for antidepressant-like activity when administered alone, increased the ARG/NO ratio in macrophages when administered concomitantly. This effect was accompanied by a decrease of cellular adherence. Concurrently, the basal metabolic activity of the cells measured with reduction of resazurin, and intracellular host defense as assessed by a synthesis of superoxide anion, were not affected by such antidepressive treatment. Our data indicate that co-administration of AMA and FLU decreases the pro-inflammatory properties of macrophages and causes a redirection of immune response toward anti-inflammatory activity, as one can anticipate in the case of an effective antidepressive treatment.
