Abstract
Circadian biology's impact on human physical health and its role in disease development and progression is widely recognized. The forefront of circadian rhythm research now focuses on translational applications to clinical medicine, aiming to enhance disease diagnosis, prognosis, and treatment responses. However, the field of circadian medicine has predominantly concentrated on human healthcare, neglecting its potential for transformative applications in veterinary medicine, thereby overlooking opportunities to improve non-human animal health and welfare. This review consists of three main sections. The first section focuses on the translational potential of circadian medicine into current industry practices of agricultural animals, with a particular emphasis on horses, broiler chickens, and laying hens. The second section delves into the potential applications of circadian medicine in small animal veterinary care, primarily focusing on our companion animals, namely dogs and cats. The final section explores emerging frontiers in circadian medicine, encompassing aquaculture, veterinary hospital care, and non-human animal welfare and concludes with the integration of One Health principles. In summary, circadian medicine represents a highly promising field of medicine that holds the potential to significantly enhance the clinical care and overall health of all animals, extending its impact beyond human healthcare.

Abstract
Context: Deregulated glucose homeostasis leads to a life-threatening metabolic disorder known as diabetes. The insulin deficiency and hyperglycaemic condition related to diabetes cause dysregulation of the immune system.Objective: This study evaluated the combined efficacy of melatonin and insulin in attenuation of lipopolysaccharide (LPS) caused inflammation, macrophage functional impairment, and oxidative stress in the spleen of diabetic mice.Materials and Methods: Multiple low doses of streptozotocin (50mg/kg B. wt.) were administered intraperitoneally to induce diabetes. Diabetes mice were divided into two sets. Set-1 contained control, diabetes, diabetes insulin (2IU/100g B.wt.) treated, diabetes melatonin (100µg/100g. B.wt.) treated, and diabetes melatonin and insulin treated groups of mice. In set II, the same number of groups as those of set I were given a single dose of LPS (50µg/mice) 24 hours before euthanization.Results and Discussion: LPS caused a significant increase in oxidative stress, circulatory proinflammatory cytokines, significant suppression of antioxidant defense system, and phagocytic index in diabetic mice. Melatonin and insulin significantly improved the adverse effects caused by LPS treatment in diabetic mice. The present study noted that combined treatment of melatonin and insulin was more effective in attenuating LPS-induced devastating effects in laboratory mice.Conclusions: The present study may suggest a combinatorial approach in the therapeutic use of melatonin and insulin to improve such devastating conditions.

Abstract
Biological rhythms in birds are driven by the master clock, which includes the suprachiasmatic nucleus, the pineal gland and the retina. Light/dark cycles are the cues that synchronize the rhythmic changes in physiological processes, including immunity. This review summarizes our investigations on the bidirectional relationships between the chicken pineal gland and the immune system. We demonstrated that, in the chicken, the main pineal hormone, melatonin, regulates innate immunity, maintains the rhythmicity of immune reactions and is involved in the seasonal changes in immunity. Using thioglycollate-induced peritonitis as a model, we showed that the activated immune system regulates the pineal gland by inhibition of melatonin production at the level of the key enzyme in its biosynthetic pathway, arylalkylamine-N-acetyltransferase (AANAT). Interleukin 6 and interleukin 18 seem to be the immune mediators influencing the pineal gland, directly inhibiting Aanat gene transcription and modulating expression of the clock genes Bmal1 and Per3, which in turn regulate Aanat.

A role for melatonin in maintaining the pro- and anti-inflammatory balance by influencing leukocyte migration and apoptosis in carp. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2015; 53:179-190.

Abstract
Melatonin is responsible for the synchronization of many physiological processes, including the immune response. Here we focus on the expression of melatonin MT1 receptors in/on leukocytes, and on the effects of melatonin administration on the inflammatory processes of carp. For the first time, we showed that fish leukocytes express MT1 receptors, implicating direct responsiveness to melatonin stimulation. Moreover, both in vitro and in vivo, melatonin modulated the immune response. The most potent effects of melatonin concerned the regulation of leukocyte migration. Melatonin reduced chemotaxis of leukocytes towards CXC chemokines in vitro. In vivo, during zymosan induced peritonitis, i.p. administration of melatonin reduced the number of neutrophils. This correlated with a melatonin-induced decrease of gene expression of the CXCa chemokine. Moreover, melatonin induced a decrease of the respiratory burst in inflammatory leukocytes. Although these data do suggest a potent anti-inflammatory function for this hormone, melatonin-induced inhibition of leukocyte apoptosis clearly indicates towards a dual function. These results show that also in carp, melatonin performs a pleiotropic and extra-pineal function that is important in maintaining the delicate pro- and anti-inflammatory balance during infection. They furthermore demonstrate that neuroendocrine-immune interaction via melatonin is evolutionary conserved.

Abstract
We demonstrate that during inflammatory responses the nuclear factor kappa B (NF-κB) induces the synthesis of melatonin by macrophages and that macrophage-synthesized melatonin modulates the function of these professional phagocytes in an autocrine manner. Expression of a DsRed2 fluorescent reporter driven by regions of the aa-nat promoter, that encodes the key enzyme involved in melatonin synthesis (arylalkylamine-N-acetyltransferase), containing one or two upstream κB binding sites in RAW 264.7 macrophage cell lines was repressed when NF-κB activity was inhibited by blocking its nuclear translocation or its DNA binding activity or by silencing the transcription of the RelA or c-Rel NF-κB subunits. Therefore, transcription of aa-nat driven by NF-κB dimers containing RelA or c-Rel subunits mediates pathogen-associated molecular patterns (PAMPs) or pro-inflammatory cytokine-induced melatonin synthesis in macrophages. Furthermore, melatonin acts in an autocrine manner to potentiate macrophage phagocytic activity, whereas luzindole, a competitive antagonist of melatonin receptors, decreases macrophage phagocytic activity. The opposing functions of NF-κB in the modulation of AA-NAT expression in pinealocytes and macrophages may represent the key mechanism for the switch in the source of melatonin from the pineal gland to immune-competent cells during the development of an inflammatory response.

Abstract
Previously, we demonstrated that experimental peritonitis in chickens was attenuated by treatment with exogenous melatonin, while the developing inflammation decreased pineal AANAT activity. This suggested the existence of a bidirectional relationship between the activated immune system and pineal gland function. The aim of the present study was to identify the step(s) in the chicken pineal melatonin biosynthetic pathway that are affected by inflammation. Peritonitis was evoked by i.p. injection of thioglycollate solution, either 2h after the start, or 2h before the end of the light period, and the animals were sacrificed 4h later. The effect of inflammation on the expression of genes encoding enzymes participating in melatonin biosynthesis in the pineal gland, i.e. tryptophan hydroxylase 1 (Tph1), dopa decarboxylase (Ddc), arylalkylamine N-acetyltransferase (Aanat) and acetylserotonin O-methyltransferase (Asmt), was evaluated by qPCR. The pineal and serum melatonin concentration as well as the content of its precursors in the pineal gland were measured, along with the activity of the relevant biosynthetic enzymes. Developing peritonitis caused an increase in the pineal levels of the Tph1 mRNA during the night and the Asmt mRNA during the day, while nocturnal Aanat transcription was reduced. Both the pineal and serum melatonin level and the pineal content of N-acetylserotonin (NAS) were decreased during the night in birds with peritonitis. The amount and activity of pineal AANAT were significantly reduced, while the activity of HIOMT was increased under these experimental conditions. These results indicate that the observed decrease in MEL biosynthesis in chickens with developing inflammation is a result of transcriptional downregulation of the Aanat gene, followed by reduced synthesis and activity of the encoded enzyme.

Abstract
Incubation of aortic rings in a culture medium produces phenomena similar to those observed with aging, i.e. oxidative stress and inflammation leading to increased nitric oxide (NO)-mediated dilation and decreased arterial sensitivity to vasoconstrictor agents. We evaluated whether melatonin protects aortic rings from such a decrease in vasoreactivity. Two concentrations of melatonin were used: 10(-8) M, EC50 for vascular MT1-MT2 receptors, and 10(-5) M, reported as anti-oxidant. Anti-oxidant capacity, inducible nitric oxide synthase (iNOS) expression and isometric contraction of thoracic aorta rings (Wistar rats) evoked by norepinephrine (NE) were assessed. Three days of incubation of aortic rings induced iNOS expression and a fall in NE-evoked contraction. When melatonin was added to the organ bath, it (10(-5) M) increased (+96%, P < 0.05), but did not restore (compared with freshly isolated rings) NE-evoked contraction. Three days of treatment with melatonin increased (10(-8) M, +99%) or restored (10(-5) M, +216%) NE-evoked contraction (compared with freshly isolated rings). The beneficial effects of 10(-8) and 10(-5) M melatonin on NE-evoked contraction were abolished in the presence of luzindole (2 x 10(-6) M, a melatonin receptor antagonist). The incubation-induced increase in iNOS expression was reduced following 3 days of melatonin administration (10(-8) and 10(-5) M). Melatonin (10(-5) M) increased catalase activity (6550 +/- 256, P < 0.05 vs. nontreated fresh aortic rings 5554 +/- 444 nmol min(-1) mg protein(-1)). In conclusion, melatonin counteracts the incubation-induced loss of agonist-evoked contraction of aortic rings by a specific receptor-mediated phenomenon involving iNOS expression; at higher melatonin concentrations, an anti-oxidant effect is probably also involved.

Abstract
The immunomodulatory action of melatonin in different animal species is already well known, although the mechanism(s) by which the indoleamine influences the immune system have yet to be fully elucidated. Previously, we have shown both anti-inflammatory and opioid-mediated influence of exogenous melatonin on thioglycollate-induced peritonitis in young chickens. In the present study, the kinetics of peritonitis and splenocyte proliferation were compared in chickens reared in both seasons under the same L:D 12:12 conditions. These two aspects of the immune response were correlated with the diurnal rhythm of pineal gland function, measured by the activity of N-acetyltransferase (NAT), a key enzyme in melatonin biosynthesis. The results revealed seasonal changes in the circadian rhythm of pineal NAT activity occurring in parallel to the natural local geophysical seasons. These changes appeared to influence the development of peritonitis and splenocyte responsiveness to mitogenic stimulation in vitro. Moreover, the existence of bidirectional communication between the pineal gland and the activated immune system was supported by the decreased activity of pineal NAT in chickens with peritonitis compared with control birds.

Abstract
This review summarizes the numerous observations published in recent years which have shown that one of the most significant of melatonin's pleiotropic effects is the regulation of the immune system. The overview summarizes the immune effects of pinealectomy and the association between rhythmic melatonin production and adjustments in the immune system as markers of melatonin's immunomodulatory actions. The effects of both in vivo and in vitromelatonin administration on non-specific, humoral, and cellular immune responses as well as on cellular proliferation and immune mediator production are presented. One of the main features that distinguishes melatonin from the classical hormones is its synthesis by a number of non-endocrine extrapineal organs, including the immune system. Herein, we summarize the presence of immune system-synthesized melatonin, its direct immunomodulatory effects on cytokine production, and its masking effects on exogenous melatonin action. The mechanisms of action of melatonin in the immune system are also discussed, focusing attention on the presence of membrane and nuclear receptors and the characterization of several physiological roles mediated by some receptor analogs in immune cells. The review focuses on melatonin's actions in several immune pathologies including infection, inflammation, and autoimmunity together with the relation between melatonin, immunity, and cancer.
