ABSTRACT Porcine reproductive and respiratory syndrome virus (PRRSV) infection induces both humoral and cellular immune responses. In this study, we investigated the changes in cytokine levels in peripheral blood between the highly pathogenic PRRSV HuN4 strain and its derivative strain HuN4-F112 obtained by serial propagation in MARC145 cells to 112 passages. The results demonstrated that pigs infected with HuN4 showed a loss of appetite, decrease in body weight, raised body temperature, and respiratory symptoms, along with interstitial pneumonia lesions. The PRRSV amounts in the pigs infected with HuN4 were 105 to 109 copies/ml in the blood and 1010 to 1011 copies/g in the lung tissues, whereas the virus amounts with HuN4-F112 were 102.15 to 103.13 copies/ml in the blood and 103.0 to 103.6 copies/g in the lungs. Moreover, the levels of interleukin 1 (IL-1), IL-6, tumor necrosis factor alpha (TNF-α), and alpha interferon (IFN-α) in peripheral blood were upregulated 7 days postinoculation with HuN4, which was earlier than in the HuN4-F112 group. Furthermore, cytokine levels in the pigs infected with HuN4 returned to normal on the 21st day postinoculation, while the levels in those infected with HuN4-F112 continued to increase. These results demonstrated that the pigs infected with the highly pathogenic PRRSV HuN4 strain generated earlier and higher levels of inflammatory cytokines, and the results also indicated that HuN4 may aggravate inflammation and damage tissues and organs. The low-pathogenic PRRSV HuN4-F112 strain induced lower levels of inflammatory cytokines, which may enhance the immune responses against the infection.

Coronavirus disease 2019 (COVID-19), with a broad range of clinical and laboratory findings, is currently the most prevalent medical challenge worldwide. In this disease, hypercoagulability and hyperinflammation, two common features, are accompanied by a higher rate of morbidity and mortality. We assessed the association between baseline inflammatory cytokine levels and coagulopathy and disease outcome in COVID-19. One hundred and thirty-seven consecutive patients hospitalized with COVID-19 were selected for the study. Baseline interleukin-1 (IL-1), IL-6, and tumor necrosis factor alpha (TNF-α) level were measured at time of admission. At the same time, baseline coagulation parameters were also assessed during the patient’s hospitalization. Clinical findings, including development of thrombosis and clinical outcome, were recorded prospectively. Out of 136 patients, 87 (~64%) had increased cytokine levels (one or more cytokines) or abnormal coagulation parameters. Among them, 58 (~67%) had only increased inflammatory cytokines, 12 (~14%) had only coagulation abnormalities, and 17 (19.5%) had concomitant abnormalities in both systems. It seems that a high level of inflammatory cytokines at admission points to an increased risk of developing coagulopathy, thrombotic events, even death, over the course of COVID-19. Early measurement of these cytokines, and timely co-administration of anti-inflammatories with anticoagulants could decrease thrombotic events and related fatal consequences.

Early Peak

During the progression of Mg deficiency in a rodent model, we have observed dramatic increases in serum levels of inflammatory cytokines [interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha)] after 3 wk on a Mg-deficient diet. Sequential analyses of these cytokine changes in the serum of rats revealed an initial rise at day 12, followed by a major elevation in all three cytokine levels by day 21. Of greater interest was an early peak in the serum level of the neuropeptide substance P after only 5 days on the diet. This “neuronal” tachykinin is thought to be released from neural tissues, and it is known to stimulate production of certain cytokines, including IL-1, IL-6, and TNF-alpha. In addition, there was a concomitant increase in histamine levels, which may have resulted from stimulation and degranulation of mast cells by substance P. Thus we hypothesize that the release of substance P may be the earliest pathophysiological event leading to stimulation of the inflammatory cytokines, which may then stimulate the free radical mechanisms of injury previously confirmed by our work.

Purpose: This study investigated the nutritional value of Misutkaru with added Gryllus bimaculatus powder (GBM) and its applicability as a healthy functional food.Methods: Chemical analysis of the moisture, crude fat, protein, and mineral contents was performed in accordance with the Association of Official Analytical Chemists (AOAC) guidelines. The amino acid and fatty acid compositions were analyzed using an automatic amino acid analyzer and gas chromatography, respectively. The levels of inflammatory cytokines tumor necrosis factor‑alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin 6 (IL‑6) induced by lipopolysaccharides in RAW 264.7 cells were measured.Results: The general composition per 100 g of GBM was 41.87 g protein, 19.75 g fat, and 28.52 g carbohydrates. The mineral content per 100 g of GBM was 889.66 mg calcium, 1189.73 mg potassium, 220.36 mg magnesium, 207.51 mg sodium, 694.81 mg phosphorus, and 15.50 mg zinc. In particular, valine (21.361 mg/kg), leucine (29.180 mg/kg), and isoleucine (15.562 mg/kg) were abundant in GBM. GBM also effectively downregulated the production of the inflammatory cytokines TNF-α, IL-1β, and IL-6 in RAW 264.7 macrophages.Conclusion: Misutkaru with added Gryllus bimaculatus powder may have potential for application in the development of food materials or foods to prevent muscle loss in elderly individuals and sarcopenia patients, build muscle, and prevent increase in blood lipid concentrations in middle aged people. In particular, as Gryllus bimaculatus is low in fat and carbohydrates, it can be used as a diet material.

Postconditioning of myocardial tissue employs short cycles of ischemia or pharmacologic agents during early reperfusion. Effects of helium postconditioning protocols on infarct size and the ischemia/reperfusion-induced immune response were investigated by measurement of protein and mRNA levels of proinflammatory cytokines. Rats were anesthetized with S-ketamine (150 mg/kg) and diazepam (1.5 mg/kg). Regional myocardial ischemia/reperfusion was induced; additional groups inhaled 15, 30, or 60 min of 70% helium during reperfusion. Fifteen minutes of helium reduced infarct size from 43% in control to 21%, whereas 30 and 60 minutes of helium inhalation led to an infarct size of 47% and 39%, respectively. Increased protein levels of cytokine-induced neutrophil chemoattractant (CINC-3) and interleukin-1 beta (IL-1β) were found after 30 or 60 min of helium inhalation, in comparison to control. 30 min of helium increased mRNA levels of CINC-3, IL-1β, interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) in myocardial tissue not directly subjected to ischemia/reperfusion. These results suggest that the effectiveness of the helium postconditioning protocol is very sensitive to duration of noble gas application. Additionally, helium was associated with higher levels of inflammatory cytokines; however, it is not clear whether this is causative of nature or part of an epiphenomenon.

ABSTRACTTo evaluate the effects of HIV on immune responses in cutaneous leishmaniasis (CL), we quantified cytokine levels from plasma and stimulated peripheral blood mononuclear cells (PBMCs) from individuals infected with HIV and/or CL. Gamma interferon (IFN-γ) and interleukin 13 (IL-13) levels and the ratio of IFN-γ to IL-10 produced in response to stimulation with solubleLeishmaniaantigens were significantly lower in HIV-Leishmania-coinfected patients than in CL-monoinfected patients.

This study investigated splenic status changes in weaned Sprague-Dawley rats induced by lipopolysaccharide. There were forty 26-day-old rats selected randomly and equally divided into two groups. The treatment group received daily single doses of lipopolysaccharide, and the control group was treated with normal saline. We conducted haematoxylin-eosin staining, immunohistochemical staining and semi-quantitative optical density analysis for both groups on the 29th, 32nd, 35th and 38th days after treatment. The results indicated that splenic marginal zone in the lipopolysaccharide group was thinner or disappeared compared to that of the saline group. However, the periarterial lymphoid sheath and the diameters of splenic lymphoid follicles appeared thicker and wider than those in the saline group (P less than 0.05). The expression of interleukin-1 beta, interleukin-6 and tumour necrosis factor alpha was mainly localized within the periarterial lymphoid sheath and splenic lymphoid follicles in the lipopolysaccharide treated rats. The integrated optical density and the average optical density in the lipopolysaccharide group were greater than those in the normal saline treated group (P less than 0.05). In conclusion, splenic immune function is probably strengthened by altering microstructures and releasing pro-inflammatory cytokines following lipopolysaccharide treatment.

ObjectiveIt was aimed to evaluate the relationship between proinflammatory cytokine levels and conversion disorder both commonly known as stress regulated.MethodBaseline proinflammatory cytokine levels–[Tumour necrosis factor alpha (TNF‐α), Interleukin‐1 beta (IL‐1β), Interleukin‐6 (IL‐6)]–were evaluated with enzyme‐linked immunosorbent assay in 35 conversion disorder patients and 30 healthy controls. Possible changes in proinflammatory cytokine levels were evaluated again, after their acute phase in conversion disorder patients.ResultsStatistically significant decreased serum TNF‐α levels were obtained in acute phase of conversion disorder. Those levels increased after acute conversion phase. There were no statistically significant difference observed between groups in serum IL‐1β and (IL‐6) levels.ConclusionsStress associated with conversion disorder may suppress immune function in acute conversion phase and may have diagnostic and therapeutic value.

ABSTRACT Infection with Neisseria meningitidis serogroup B is responsible for fatal septicemia and meningococcal meningitis. The severity of disease directly correlates with the production of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), IL-6, and IL-8. However, the source of these cytokines has not been clearly defined yet. Since bacterial infection involves the activation of dendritic cells (DCs), we analyzed the interaction of N. meningitidis with monocyte-derived DCs. Using N. meningitidis serogroup B wild-type and unencapsulated bacteria, we found that capsule expression significantly impaired neisserial adherence to DCs. In addition, phagocytic killing of the bacteria in the phagosome is reduced by at least 10- to 100-fold. However, all strains induced strong secretion of proinflammatory cytokines TNF-α, IL-6, and IL-8 by DCs (at least 1,000-fold at 20 h postinfection [p.i.]), with significantly increased cytokine levels being measurable by as early as 6 h p.i. Levels of IL-1β, in contrast, were increased only 200- to 400-fold at 20 h p.i. with barely measurable induction at 6 h p.i. Moreover, comparable amounts of cytokines were induced by bacterium-free supernatants of Neisseria cultures containing neisserial lipooligosaccharide as the main factor. Our data suggest that activated DCs may be a significant source of high levels of proinflammatory cytokines in neisserial infection and thereby may contribute to the pathology of meningococcal disease.

Persistent hyperglycemia is known to cause enhanced generation of reactive oxygen species in diabetes. Several inflammatory cytokines are induced by oxidative stress, and their release also leads to increased oxidative stress; this makes oxidative stress one of the important factors in the development of chronic inflammation and other immune responses. These have been implicated in the development of diabetic complications such as nephropathy and cardiomyopathy. Anchomanes difformis has been shown to possess antioxidant and anti-inflammatory potentials. The present study investigated the immunomodulatory potential and the antiapoptotic ability of Anchomanes difformis to ameliorate heart toxicity and injury in type II diabetes. Two weeks of fructose (10%) administration followed by single intraperitoneal injection of streptozotocin (40 mg/kg) were used to induce type II diabetes in male Wistar rats. Leaf extract (aqueous) of Anchomanes difformis (200 and 400 mg/kg) was administered orally for six weeks. Blood glucose concentrations and body weights before and after interventions were determined. Interleukin (IL)-1β, IL-6, IL-10, IL-18, monocyte chemoattractant protein 1 (MCP-1), and tumor necrosis factor alpha (TNFα) were measured in the heart homogenates. Catalase (CAT), superoxide dismutase (SOD), total protein, oxygen radical absorbance capacity (ORAC), ferric reducing antioxidant power (FRAP), thiobarbituric acid reactive substances (TBARS), and heart-type fatty acid-binding protein (H-FABP) levels were determined. Expressions of transcription factors (Nrf 2 and NFkB/p65) and apoptotic markers were also investigated in the heart. Anchomanes difformis administration reduced pro-inflammatory cytokines, increased anti-inflammatory markers, and enhanced antioxidant defense in the heart of diabetic treated animals. Anchomanes difformis is a new, promising therapeutic agent that can be explored for the treatment of pathological conditions associated with immune responses and will be a useful tool in the management of associated diabetic complications.
