6-Hydroxydopamine induces brain vascular endothelial inflammation.Disruption of the blood-brain barrier associated with endothelial dysfunction is an important hallmark of Parkinson's disease (PD). 6-Hydroxydopamine (6-OHDA) is a synthetic dopamine derivate often used to model PD as it results in retrograde degeneration of striatal dopaminergic (DA) terminals. Presently, the effects of 6-OHDA on endothelial dysfunction remain unknown. Using a 6-OHDA rodent model of PD, we found that administration of 6-OHDA could increase the expression of endothelial adhesion molecules, such as intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and E-selectin. An in vitro study displayed that treatment with 6-OHDA increased the release of these molecules in human brain microvascular endothelial cells in a dose-dependent manner. Correspondingly, 6-OHDA significantly increased attachment of THP-1 monocytes to brain endothelial cells. In addition, real-time polymerase chain reaction and enzyme-linked immunosorbent assay results indicated that 6-OHDA elevated the production of proinflammatory cytokines, such as interleukin-1β, interleukin-6, and tumor necrosis factor-α. Furthermore, 6-OHDA treatment increased the expression of cyclooxygenase-2 and inducible nitric oxide synthase, as well as the production of prostaglandin E2 and nitric oxide. Importantly, 6-OHDA elevated the transcriptional activity of NF-кB by increasing the phosphorylation, degradation, and subsequent nuclear translocation of p65. Mechanistically, the angiotensin II type 1 receptor was found to mediate 6-OHDA-induced endothelial dysfunction. Our findings suggest that 6-OHDA-induced endothelial inflammation may play an important role in the pathogenesis of PD. © 2017 IUBMB Life, 2017.

Immunological mechanism of low-dose priming radiation resistance in walker-256 tumor model mice.The aim of the present study was to investigate whether low-dose priming radiation induces antitumor immunity that can be augmented by the modulation of natural killer (NK) cell and cytokine activity using a mouse tumor model. Walker-256 cells were injected into the right flank of male BALB/c mice. At 7 days after inoculation, mice were divided into three groups, including group 1,2,3. In group 1 the mice were without radiation, in group 2 the mice were received 2 Gy radiation only, and in group 3 the mice were radiated with a priming dose of 75 mGy followed by 2 Gy radiation after 24 h. On day 21 following the radiation, the tumors were removed and the tumor index (tumor weight as a percentage of body weight) was calculated. At 1, 7, 14 and 21 days following the 2 Gy radiation, mouse splenocytes were isolated to analyze the NK activity and measure the production of the cytokines interleukin-1β, interferon-γ and tumor necrosis factor-α by ELISA. Apoptosis was also measured by flow cytometry. The results demonstrated that priming radiation significantly delayed the tumor growth and prolonged the median survival time to 38 days compared with the 31-day survival in the 2 Gy radiation group. The percentage of apoptotic cells was significantly higher in the mice that received 75 mGy + 2 Gy radiation compared with that in the mice that received 2 Gy alone; by contrast, mice that were not irradiated exhibited a relatively low level of apoptosis. The primed mice had a higher level of NK activity as compared with the mice exposed to 2 Gy radiation only or mice that were not irradiated. Furthermore, cytokine expression remained at a higher level in mice receiving priming dose of radiation compared that in the mice receiving only 2 Gy radiation. In conclusion, the results indicated that low-dose priming X-ray radiation may enhance the NK activity and the levels of cytokines, and that the immune response serves an important role in anticancer therapy, including radiotherapy.

The low molecular weight fraction of human serum albumin upregulates COX2, prostaglandin E2, and prostaglandin D2 under inflammatory conditions in osteoarthritic knee synovial fibroblasts.The ability to decrease inflammation and promote healing is important in the intervention and management of a variety of disease states, including osteoarthritis of the knee (OAK). Even though cyclooxygenase 2 (COX2) has an established pro-inflammatory role, evidence suggests it is also critical to the resolution that occurs after the initial activation phase of the immune response. In this study, we investigated the effects of the low molecular weight fraction of 5% human serum albumin (LMWF-5A), an agent that has proven to decrease pain and improve function in OAK patients after intra-articular injection, on the expression of COX2 and its downstream products, prostaglandins (PGs).

Aldose Reductase Mediates NLRP3 Inflammasome-Initiated Innate Immune Response in Hyperglycemia-Induced Thp1 Monocytes and Male Mice.Despite recent studies that show oxidative stress-generated reactive oxygen species (ROS) regulate NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome-mediated innate immune response in various diabetic complications, the mechanism by which ROS activate innate immune response is not well understood. We have shown previously that aldose reductase (AR), besides reducing glucose, reduces lipid aldehydes and their glutathione conjugates and participates in various oxidative stress-induced inflammatory pathways. To understand the role of AR in ROS-induced innate immune response, we have investigated the mechanism(s) by which AR activates hyperglycemia-induced NLRP3 inflammsome-initiated innate immune response in Thp1 monocytes and in streptozotocin (STZ)-induced diabetic mice. In Thp1 monocytes, inhibition or ablation of AR prevented high-glucose-induced activation of NLRP3 inflammasome and caspase-1 and release of the innate immune cytokines interleukin (IL)-1β and IL-18. AR inhibition in Thp1 cells also prevented the high-glucose-induced generation of ROS, influx of Ca2+, efflux of K+, and activation of Lyn, Syk, and PI3K. Furthermore, the AR inhibitor fidarestat prevented the expression of NLRP inflammasome components in STZ-induced diabetic mouse heart and aorta, and also prevented the release of various cytokines in the serum. Collectively, our data suggest that AR regulates hyperglycemia-induced NLRP3 inflammasome-mediated innate immune response by altering the ROS/Lyn/Syk/PI3K/Ca2+/K+ signals.

Honokiol improved chondrogenesis and suppressed inflammation in human umbilical cord derived mesenchymal stem cells via blocking nuclear factor-κB pathway.Cartilage degradation is the significant pathological process in osteoarthritis (OA). Inflammatory cytokines, such as interleukin-1β (IL-1β), activate various downstream mediators contributing to OA pathology. Recently, stem cell-based cartilage repair emerges as a potential therapeutic strategy that being widely studied, whereas, the outcome is still far from clinical application. In this study, we focused on an anti-inflammatory agent, honokiol, which is isolated from an herb, investigated the potential effects on human umbilical cord derived mesenchymal stem cells (hUC-MSCs) in IL-1β stimulation.

Single nucleotide polymorphisms associated with P2X7R function regulate the onset of gouty arthritis.Gout is an inflammatory disease that is caused by the increased production of Interleukin-1β (IL-1β) stimulated by monosodium urate (MSU) crystals. However, some hyperuricemia patients, even gouty patients with tophi in the joints, never experience gout attack, which indicates that pathogenic pathways other than MSU participate in the secretion of IL-1β in the pathogenesis of acute gouty arthritis. The ATP-P2X7R-IL-1β axis may be one of these pathways.

The diurnal pattern of salivary IL-1β in healthy young adults.Disruption in circadian rhythm affects the production of inflammatory cytokines. Understanding how it behaves in diseased conditions is essential. Despite the role of the interleukin-1β (IL-1β), a potent inflammatory cytokine, in human diseases, little is known about the steady-state circadian rhythm of IL-1β in healthy individuals. This short study investigates the diurnal pattern of salivary IL-1β throughout the day in healthy young adults. Twelve participants provided saliva samples at various times throughout the day. Salivary IL-1β were assessed using enzyme-linked immunosorbent assay (ELISA) and Western blot analysis. Salivary IL-1β levels were highest at 0430 h and lowest at 0000 h and shared a similar diurnal pattern to that of salivary IL-6. Western blot analysis showed that these levels correspond to the mature form of IL-1β. Our findings are important as it established the diurnal pattern of salivary IL-1β is fluctuating normally throughout the day. The findings also open an incredible opportunity for developing research conducted in the field with saliva as the diagnostic tool.
