“…The majority of immune cells (PMNs, macrophages, T and B lymphocytes, and NK cells) express β2-adrenergic receptors on their surface. Excitation of the SNS causes the release of catecholamine into the circulation, which exerts their effects on immune cells that express adrenergic receptors on their surface [ 57 ]. These effects cause changes in immune cellular trafficking, proliferation, antibody production, and cytokine secretion and activity [ 58 , 59 ].…”

Dairy cows are exposed to various stressors during their production cycle that makes them more susceptible to various diseases. Phagocytes (neutrophils and macrophages) are important soldiers of the innate immune system. Neutrophils are the first responders to an inflammatory response and stress and kill pathogens by generating reactive oxygen species and by the release of various antimicrobial peptides, enzymes, neutrophil extracellular trap formation, etc. Macrophages, the other phagocytes, are also the cleanup crew for the innate immune system that removes debris, pathogens, and dead neutrophils later on after an inflammatory response. The neuroendocrine system along with phagocytes exhibits an immunomodulatory potential during stressful conditions. Neuroendocrine system directly affects the activity of phagocytes by communicating bidirectionally through shared receptors and messenger molecules such as hormones, neurotransmitters, or cytokines. Different immune cells may show variable responses to each hormone. Short time exposure to stress can be beneficial, but repeated or extended exposure to stress may be detrimental to the overall health and well-being of an animal. Although some stresses associated with farming practices in dairy cows are unavoidable, better understanding of the interactions occurring between various stress hormones and phagocytic cells can help to reduce stress, improve productivity and animal welfare. This review highlights the role played by various stress hormones in modulating phagocytic cell performance of dairy cattle under inflammatory conditions.

“…Catecholamines are released into the blood during stress, which activate glycogenolysis, resulting in increases in blood glucose and muscle lactic acid concentrations 3 . During transportation, contracting muscles need a continuous supply of ATP, which is provided by the glycolytic pathway 20 . In healthy rested animals, postmortem muscle glycogen levels are high, while stressed animals have lower levels of glycogen 21 .…”

Studies exploring the transcriptome of stress and its effects on meat quality are very limited, particularly in goats. Fifty-four male Spanish goats (8-mo old; BW = 29.7 ± 2.03 kg) were randomly subjected to one of three treatments (TRT; n = 18 goats/treatment): (1) transported for 180 min, (2) transported for 30 min, or (3) held in pens (control) to analyze the transcriptome of stress and meat quality in goats using RNA-seq technology. Blood samples were collected before and after treatment, and meat samples were collected after humane slaughter for stress hormone, meat quality (Longissimus dorsi), and transcriptomic analysis. Plasma epinephrine concentrations were higher (P < 0.01) in 180 min and 30 min groups compared to the control group; however, norepinephrine concentrations were not affected by the treatment. Muscle glycogen concentrations (15 min postmortem) were lower (P < 0.01) in both 30 min and 180 min groups compared to the control group. Calpastatin levels were higher (P < 0.01) in 180 min and 30 min groups than the control group. Warner–Bratzler shear force values of loin chops were the highest in the 180 min group (4 ± 0.15, kg), lowest in the control group (3.51 ± 0.10, kg), and intermediate in the 30 min group (3.78 ± 0.09, kg; P < 0.01) both at day 1 and day 6 aging time. Additionally, desmin levels of day 6 samples were lowest in the control group, highest in 180 min group, and intermediate in 30 min group (P < 0.05). RNA-seq results showed that a total of 10,633 genes were differentially expressed (5194 up regulated; 5439 down regulated) among all comparisons (blood and day 1 and day 6 muscle samples). Among these differentially expressed genes (DEGs), KLF9, AMPK, FOXO3, PTX3, GADD45, PTPN1, CASP7, MAPK4, HSPA12A, and JAK-STAT were probably associated with the effects of stress on skeletal muscle proteins and involved in biological process such as cellular response to corticosteroid stimulus, endoplasmic reticulum stress, insulin resistance, DNA repair, apoptosis, MAPK cascade and regulation of proteolysis. The KEGG analysis revealed that AMPK and JAK-SAT signaling pathways and autophagy were among the top 20 enriched pathways in our treatment comparisons. The results provide an understanding of the genes and pathways involved in stress responses and related changes in postmortem muscle metabolism and meat quality characteristics in goats.

“…Catecholamines with an essential physiological role include dopamine, norepinephrine and adrenaline, and their secretion is unevenly distributed in the central and peripheral nervous system but also in the endocrine system (Pan et al, 2018). Thus, the synthesis and release of catecholamines is found in the neuronal, lymph nodes but also in the adrenal medulla, the area of nerve origin of the adrenal gland (O'Neill, 2019). The release of catecholamines into the bloodstream is a rapid process, at the moment, which leads to rapid amplification of motor performance (especially by increasing muscle oxygenation), cardio-respiratory rate, mobilization of energy reserves and causes a wide integration of stressors central nervous system (McMorris et al, 2016).…”

Problem statement in the context of performance sports, along with normal physiological reactions, there is competitive stress, which varies in relation to the type of sport practiced. Purpose of study: to test sports subjects at the beginning and end of the application of the intervention program. To test the biochemical and physiological condition of athletes and to modulate the reactivity of athletes to the stress of competition. Methods we proposed a training scheme that includes assessing the hormonal status of athletes by non-invasive methods, such as salivary and urinary determination. Research designs: the subjects of the study were juniors aged 14-16 from sports clubs in Satu-Mare County and Cluj-Napoca. Sampling: were urine and saliva samples were taken before and after training. These were in average volumes of 1 ml. Findings and Results: the statistics were processed with GraphPad Prism 5 software, with the student t test for unmatched values associated with Welch's correction. For biochemical markers that have been dosed the statistical significance is p <0.05 with a probability > 95%. Discussion: biochemical parameters for saliva and urine were assayed by immunochemical and spectrophotometric methods. It has been shown that specific training in this case contributes to the biochemical reaction of adaptation to stress (coping). Conclusions this approach is applicable in planning pre-competitive training to target the level of positive and negative emotions (functional and dysfunctional) in association with a level of stress.
