Elimination Half-Lives of Acute Phase Proteins in Rats and Beagle Dogs During Acute Inflammation
ABSTRACT The half-lives of typical acute phase proteins in rats and beagle dogs during acute inflammation were investigated. Acute inflammation was induced by injection of turpentine oil in rats and administration of indomethacin in beagle dogs. Serum concentrations of α2-macroglobulin (α2M) and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay and α1-acid glycoprotein (AAG) was measured by single radial immunodiffusion. Half-life was calculated as 0.693/elimination rate constant (K). The mean half-lives in the terminal elimination phase of α2M and AAG were 68.1 and 164.8 h, respect...

Lymphoid-Like Structures with Distinct B Cell Areas in Kidney Allografts are not Predictive for Graft Rejection. A Non-human Primate Study
Abstract Kidney allograft biopsies were analyzed for the presence of B cell clusters/aggregates using CD20 staining. Few B cells were found in the diffuse interstitial infiltrates, but clusters of B cells were found in nodular infiltrates. These nodular infiltrates were smaller shortly after transplantation, and their size increased over time. At the time of clinical rejection, the nodules often presented as tertiary lymphoid structures (TLS) with lymphoid-like follicles. The presence of small B cell clusters during the first 2 months after transplantation was not associated with early rejection. Even in animals ...

Fusion Peptides CPU1 and CPU2 Inhibit Matrix Metalloproteinases and Protect Mice from Endotoxin Shock Within a Strict Time Window
Abstract Endotoxin shock induction in mice is a commonly used animal model to evaluate the protective effect of biologically active reagents. After an lipopolysaccharides (LPS) stimulus, matrix metalloproteinase-8 (MMP-8) and matrix metalloproteinase-9 (MMP-9) are rapidly degranulated and released by neutrophils, aside other enzymes and effector molecules. MMPs cleave extracellular matrix components and cytokines, and such processes contribute to shock syndrome development. CPU1 and CPU2 are two peptide MMP inhibitors with different in vitro IC50 values to several key enzymes, including MMP-8 and MMP-9. In vivo wo...

Ox-LDL Upregulates IL-6 Expression by Enhancing NF-κB in an IGF2-Dependent Manner in THP-1 Macrophages
Abstract Interleukin 6 (IL-6) is a pro-inflammatory cytokine that is well established as a vital factor in determining the risk of coronary heart disease and pathogenesis of atherosclerosis. Moreover, accumulating evidences have shown that oxidized low-density lipoprotein (ox-LDL) can promote IL-6 expression in macrophages. Nevertheless, the underlying mechanism of how ox-LDL upregulates IL-6 expression remains largely unexplained. We found that the expression of insulin-like growth factor 2 (IGF2), nuclear factor kappa B (NF-κB), and IL-6 was upregulated at both the messenger RNA (mRNA) and protein levels in a d...

The Roles of Egr-2 in Autoimmune Diseases
Abstract Being a member of the early growth response (Egr) family of transcription factors, Egr-2 is expressed in a variety of cell types of the immune system. Recent findings imply that Egr-2 is important in the development and function of T helper (Th) 17 cell, regulatory T (Treg) cell, as well as dendritic cell (DC). Although these cells perform significantly in the pathogenesis of autoimmune diseases, such as systemic lupus erythematosus, multiple sclerosis, and systemic sclerosis, the roles of Egr-2 in the pathogenesis of autoimmune diseases can not be neglected.

These effects were unaltered after 1 day, partially reversed after 3 days, and inhibited ...

Silymarin Attenuates Airway Inflammation Induced by Cigarette Smoke in Mice
In this study, we investigated the effects of silymarin, a polyphenolic flavonoid isolated from the seeds and fruits of milk thistle, on CS-induced airway inflammation and oxidative stress in mice and the possible mechanisms. BALB/c mice were exposed to CS for 2 h twice daily, 6 days per week for 4 weeks. Silymarin (25, 50 mg/kg · day) was administered intraperitoneally 1 h before CS exposure. Bronchoalveolar lavage fluid (BALF) was acquired for cell counting and the detection of pro-inflammatory cytokine levels. Lung tissue was collected for histological examination, myeloperoxidase (MPO) activity assay, superoxide d...

Aurora Kinase A Regulates M1 Macrophage Polarization and Plays a Role in Experimental Autoimmune Encephalomyelitis
Abstract Macrophage polarization is a dynamic and integral process of tissue inflammation and remodeling. Here we demonstrate an important role of Aurora kinase A in the regulation of inflammatory M1 macrophage polarization. We found that there was an elevated expression of Aurora-A in M1 macrophages and inhibition of Aurora-A by small molecules or specific siRNA selectively led to the suppression of M1 polarization, sparing over the M2 macrophage differentiation. At the molecular level, we found that the effects of Aurora-A in M1 macrophages were mediated through the down-regulation of NF-κB pathway and subsequ...

MAPK and NF-κB Pathways Are Involved in Bisphenol A-Induced TNF-α and IL-6 Production in BV2 Microglial Cells
Abstract Microglial activation has been reported to play an important role in neurodegenerative diseases by producing pro-inflammatory cytokines. Bisphenol A (BPA, 2,2-bis (4-hydroxyphenyl) propane), known as a ubiquitous endocrine-disrupting chemical, is reported to perform both mimic- and anti-estrogen properties; however, whether it affects cytokine production or immune response in central nervous system remains unclear. The present study was aimed to explore whether BPA was involved in inflammatory action and to investigate the potential mechanisms in microglial cells. BV2, the murine microglial cell line, wa...

Recruitment of Gr1 + CD11b + F4/80 + Population in the Bone Marrow and Spleen by Irradiation-Induced Pulmonary Damage
Abstract Radiation-induced lung injury is a kind of sterile inflammation, which may lead to morbidity and mortality. The mechanism by which ionizing radiation activate the immune system is not well understood. In the present study, we have investigated the immunological responses induced by local irradiation-induced damage in mouse lung. The left lungs of C57BL/6 mice were irradiated at a high dose of 100 Gy. The histology of the lungs and spleen showed evidences of alveolar inflammation and congestion at 2 weeks after X-ray treatment. Also, prominent increase in cells expressing the cell surface markers, Gr+CD...
