Pleural effusion is associated with multiple benign and malignant conditions. Currently no biomarkers differentiate malignant pleural effusion (MPE) and benign pleural effusion (BPE) sensitively and specifically. The present study identified a novel combination of biomarkers in pleural effusion for differentiating MPE from BPE by enrolling 75 patients, 34 with BPE and 41 with MPE. The levels of lactate dehydrogenase, glucose, protein, and total cell, neutrophil, monocyte and lymphocyte counts in the pleural effusion were measured...

Background High dietary salt intake contributes to the development of autoimmune/inflammatory diseases including metabolic syndrome (MetS) which potassium supplementation can potentially reverse. T helper (Th) 17 cells as well as its production interleukin (IL)-17A are involved in the pathogenesis of MetS. The polarization of Th17 cells and enhanced IL-17A production induced by high salt might increase the risk of autoimmune/inflammatory diseases. Methods 45 normotensive subjects (aged 29 to 65 years) were enrolled from a rural community of Northern China at random...

Interleukin-1 receptor associated kinase 4 (IRAK4) plays a critical role in innate immune signaling by Toll-like receptors (TLRs), and loss of IRAK4 activity in mice and humans increases susceptibility to bacterial infections and causes defects in TLR and IL1 ligand sensing. However, the mechanism by which IRAK4 activity regulates the production of downstream inflammatory cytokines is unclear. Using transcriptomic and biochemical analyses of human monocytes treated with a highly potent and selective inhibitor of IRAK4, we show that IRAK4 kinase activity controls the activation of the transcription factor IRF5, a transcription factor implicated in the pathogenesis of multiple autoimmune diseases...

Action mechanisms underlying various biological activities of collagen peptides (CPs) remained to be elucidated. Cytokines may play an important role in mediating these health benefits of CPs. This study aimed to systemically examine the cytokines in skin and blood regulated by CPs intake. Thirteen-month-old female Kunming mice were administered with CPs for 2 months (0 or 400 mg/kg bodyweight/day). The cytokines in skin and plasma were analysed using a 53-cytokine array and corresponding ELISA kits. In skin, CPs intake significantly down-regulated placenta growth factor (PIGF-2), insulin-like growth factor (IGF)-binding protein (IGFBP) -2 and IGFBP-3, and up-regulated platelet factor 4 (PF4), serpin E1 and transforming growth factor (TGF)-β1 ...

Interleukin-4 (IL-4)-induced T helper (Th) 2 cells promote susceptibility to the protozoan parasite Leishmania major, while conferring immunity to the intestinal trematode Schistosoma mansoni Here, we report that abrogation of IL-4 receptor alpha (IL-4Rα) signaling on B cells in BALB/c mice (mb1(cre)IL-4Rα(-/lox)) transformed nonhealer BALB/c to a healer phenotype with an early type 1 and dramatically reduced type 2 immune response and an absence of ulceration and necrosis during cutaneous leishmaniasis. From adoptive reconstitution and mixed bone-marrow chimera studies in B cell-deficient (µMT) mice, we reveal a central role for B cell-derived IL-4 and IL-4Rα in the optimal induction of the susceptible type 2 phenotype to L...

Brucellosis is a globally distributed zoonotic disease that causes animal and human diseases. Although effective, the current Brucella vaccines (strain M5-90 or others) have several drawbacks. The first is their residual virulence for animals and humans and the second is their inability to differentiate natural infection from that caused by vaccination. In the present study, Brucella melitensis M5-90 manB mutant (M5-90ΔmanB) was generated to overcome these drawbacks. M5-90ΔmanB showed significantly reduced survival in macrophages and mice, and induced strong protective immunity in BALB/c mice...

Acinetobacter baumannii is a tiny, plump and rod-shaped Gram-negative coccobacillus, notorious as an opportunistic pathogen, which is now being considered by CDC as a serious public health threat. Preventing colonization may be a better therapeutic choice using microbiota to protect against A. baumannii transmission. Human microbiota not only regulates immune homeostasis as well provides essential health benefits therefore discovering the interface due microbiota in host immune system will allow to recognise novel immuno- or microbe-based therapies...

It is essential to improve animal vaccine for brucellosis since conventional vaccines are residual virulent and poor protective effect, limit their applications. To solve these problems, the recombinant DNA vaccines were appeared, which could improve protective immunity and were attenuated to animals. In current research, the recombinant DNA vaccine (pVGntR) based on transcriptional regulator GntR of Brucella abortus (B. abortus) was constructed. The results show that pVGntR is significantly more protective than the conventional RB51 vaccine...
