BACKGROUND: Haemodialysis (HD) patients are predisposed to dysregulated fluid balance leading to extracellular water (ECW) expansion. Fluid overload has been closely linked with outcome in these patients. This has mainly been attributed to cardiac volume overload, but the relation between abnormalities in fluid status with micro- and macrovascular dysfunction has not been studied in detail. We studied the interaction of macro- and microvascular factors in states of normal and over- hydration in HD-dependent CKD...

Several immune-related markers have been implicated in basal cell carcinoma (BCC) pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL)-17, IL-23 and IL-22, play a significant role in cutaneous inflammatory diseases, but their involvement in skin carcinogenesis is controversial and is poorly investigated in BCC...

OBJECTIVE: Body's iron metabolism is at one dynamic balance status, and abnormal iron metabolism may lead to renal anemia. Inflammation stimuli may lead to abnormal iron metabolism and aggravation of chronic failure anemia. Hepcidin can regulate iron metabolic homeostasis, further mediating renal anemia. Interleukin-10 (IL-10) is an inflammatory inhibitor, but with an unclear function in the regulation of hepcidin expression. MATERIALS AND METHODS: BALB/c mice were randomly assigned into three groups: control group; lipid polysaccharide (LPS) group, which received 0...

Mycobacterium tuberculosis PE/PPE family proteins play a vital role in antigenic diversity, host-pathogen interactions, and immune evasion. As secreted by ESX-5 system, M. tuberculosis PPE27 is related to the growth and virulence of the bacilli. In this study, we expressed PPE27 in the nonpathogenic fast growing Mycobacterium smegmatis. We found that the recombinant strain exhibits higher survival rate under several hostile conditions in vitro and longer persistence in mouse tissues. The survival of the recombinant strains was also enhanced in the mouse macrophage ANA-1, accompanied by higher level of host cell death, higher secretion of tumor necrosis factor-alpha, and a slightly higher amount of interleukin (IL)-1β, which could be abolished by the nuclear factor-κB, p38, and ERK inhibitors...

A mix of flavonoids comprising baicalin (BA) and catechin showed effective impacts on controlling the progress of knee osteoarthritis (OA). However, little is known about the underlying mechanisms. The influences of BA on the transcriptional levels of a series of proinflammatory genes were measured using real-time reverse transcription and polymerase chain reaction (RT-PCR). The expressions of proteins involved in nuclear factor-κB (NF-κB) activation were detected by Western blot. The in vitro results were confirmed in a mouse OA model...

The enrichment of CD20(+) and CD138(+) immune cells were previously associated with improved survival in colorectal cancer (CRC). We previously discovered that the resected tumors in CRC patients were highly enriched with interleukin (IL)-10-producing CD19(lo)CD27(hi) plasmablasts with potential suppressor functions. It is still unknown what roles the CD19(lo)CD27(hi) plasmablasts play in CRC patients. In this study, we first demonstrated that B cells from peripheral blood mononuclear cells (PBMCs) could be stimulated to resemble tumor-infiltrating plasmablasts using a coculture containing Caco-2 and heat-killed bacteria...

The problem of new psychoactive substances (NPS) is emerging globally. However, the immunotoxicity of synthetic cannabinoids is not evaluated extensively yet. The purpose of the present study was to investigate whether synthetic cannabinoids (JWH-210 and JWH-030) induce adverse effects on lymphoid organs, viability of splenocytes and thymocytes, and immune cell activator and cytokines in mice. JWH-210 (10 mg/kg, 3 days, i.p.) is more likely to have cytotoxicity and reduce lymphoid organ weight than JWH-030 of ICR mice in vivo...

Interleukin 6 (IL-6) was abundant in the tumor microenvironment and played potential roles in tumor progression. In our study, the expression of IL-6 in tumor tissues from 36 gastric cancer (GC) patients was significantly higher than in non-tumor tissues. Moreover, the number of CD163(+)CD206(+) M2 macrophages that infiltrated in tumor tissues was significantly greater than those infiltrated in non-tumor tissues. The frequencies of M2 macrophages were positively correlated with the IL-6 expression in GC tumors...

One subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by the development of a T-helper type 2 (Th2) response and eosinophilic infiltration. Here, we aimed to establish an eosinophilic CRSwNP murine model, which would be essential to understand the underlying pathogenesis and establish a treatment strategy. C57BL/6 mice were challenged intranasally with a mixture of an Aspergillus oryzae-derived protease (AP) and ovalbumin (OVA) for 6, 8, or 12 consecutive weeks (12 mice/group); control mice received the same volume of phosphate-buffered saline for 12 weeks (n = 12)...

Anesthesia and surgery have an impact on inflammatory responses, which influences perioperative homeostasis. Inhalational and intravenous anesthesia can alter immune-system homeostasis through multiple processes that include activation of immune cells (such as monocytes, neutrophils, and specific tissue macrophages) with release of pro- or anti-inflammatory interleukins, upregulation of cell adhesion molecules, and overproduction of oxidative radicals. The response depends on the timing of anesthesia, anesthetic agents used, and mechanisms involved in the development of inflammation or immunosuppression...
