Abstract
Neutrophils are essential components of the immune system and have vital roles in the pathogenesis of autoimmune disorders. As effector cells, neutrophils promote autoimmune disease by releasing cytokines and chemokines cascades that accompany inflammation, neutrophil extracellular traps (NETs) regulating immune responses through cell-cell interactions. More recent evidence has extended functions of neutrophils. Accumulating evidence implicated neutrophils contribute to tissue damage during a broad range of disorders, involving rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), primary sjögren's syndrome (pSS), multiple sclerosis (MS), crohn's disease (CD), and gout. A variety of studies have reported on the functional role of neutrophils as therapeutic targets in autoimmune diseases. However, challenges and controversies in the field remain. Enhancing our understanding of neutrophils' role in autoimmune disorders may further advance the development of new therapeutic approaches.

Abstract
Twelve undescribed lanostane-type triterpenes, and twenty-two known triterpenes were isolated and identified from a medicinal bracket fungus Fomitopsis pinicola (Sw.) P. Karst. The structures of these compounds were determined by spectroscopic and spectrometric analyses. The antiinflammatory potential of thirty-two triterpene compounds was evaluated using neutrophils as an assay model, and pinicolasin J was the most potent inhibitor of superoxide anion generation and elastase release, with IC50 values of 1.81 ± 0.44 and 2.50 ± 0.64 μM, respectively. This study provides scientific insight into the nutritional supplement value and medicinal development of Fomitopsis pinicola.

Abstract
The literature shows that phenolic compounds possess important antioxidant and anti-inflammatory activities; however, the mechanism underlying these effects is not elucidated yet. The genus Calea is used in folk medicine to treat rheumatism, respiratory diseases, and digestive problems. In this context, some phenolic compounds were isolated with high purity from Calea uniflora Less. and identified as noreugenin (NRG) and α-hydroxy-butein (AH-BU). The aim of this study was to analyze the effect of these compounds on cell viability, the activity of myeloperoxidase (MPO), and apoptosis of mouse neutrophils using ex vivo tests. Furthermore, the effect of these compounds on the cytokines, interleukin 1 beta (IL-1β), interleukin 17A (IL-17A), and interleukin 10 (IL-10), and oxidative stress was investigated by analyzing lipid peroxidation (the concentration of thiobarbituric acid reactive substances (TBARS)) and activities of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST), using a murine model of neutrophilic inflammation. The NRG and AH-BU reduce MPO activity and increase neutrophil apoptosis (p < 0.05). These compounds reduced the generation of oxygen reactive species and IL-1β and IL-17A levels but increased IL-10 levels (p < 0.05). This study demonstrated that NRG and AH-BU show a significant anti-inflammatory effect by inhibiting the MPO activity and increasing neutrophil apoptosis in primary cultures of mouse neutrophils. These effects were at least partially associated with blocking reactive species generation, inhibiting IL-1β and IL-17A, and increasing IL-10 levels.

Abstract
Background Polyphenol catechins from green tea, particularly (−)-epigallocatechin-3-gallate (EGCG), exhibits numerous beneficial health effects, although the mechanisms remain unclear. Methods In this study, the mechanism of EGCG-mediated healing in an experimentally injured zebrafish model was examined at the cellular and molecular level using confocal microscopy and gene expression analysis. Results The mechanisms of action of EGCG were shown to involve: (1) reducing neutrophil response (accumulation, travel speed, and distance) and (2) downregulating the expression of IL-1β, TNFα, and related signaling pathways. As determined by dynamic time-lapse tracking studies, the local accumulation of neutrophils with high migration speeds after wounding (n=33 cells, v=0.020 μm/s, d=37.8 μm), underwent significant reduction following treatment with EGCG doses of 300 μM (n=22 cells, v=0.013 μm/s, d=39.5 μm) and 600 μM (n=18 cells, v=0.008 μm/s, d=9.53 μm). Reverse transcription polymerase chain reaction studies revealed that several signature genes in the IL-1β, TNFα, and related signaling pathways were downregulated after EGCG treatment. Conclusion The convenience, transparency, and simplicity of the zebrafish model facilitate tracking of fluorescent neutrophils in real time, in order to monitor inflammation, and assess the impact of therapeutic agents.

Abstract
Inflammation is the response of the body to noxious stimuli such as infections, trauma, or injury. Experimental studies have shown that vanillic acid has anti-inflammatory effects. The objective of this study was to investigate the anti-inflammatory and antipyretic properties of the derivative of vanillic acid, isopropyl vanillate (ISP-VT), in mice. The results of this study indicated that ISP-VT reduced paw edema induced by carrageenan, dextran sulfate (DEX), compound 48/80, serotonin, bradykinin (BK), histamine (HIST), and prostaglandin E2 (PGE2). Furthermore, ISP-VT reduced recruitment of leukocytes and neutrophils and reduced its adhesion and rolling, and decreased myeloperoxidase enzyme activity (MPO), cytokine levels (tumor necrosis factor-α and interleukin-6), and vascular permeability. ISP-VT also significantly reduced the expression of cyclooxygenase-2 (COX-2) in subplantar tissue of mice. ISP-VT inhibited COX-2 selectively compared to the standard drug. Our results showed that although ISP-VT binds to COX-1, it is less toxic than indomethacin, as evidenced by MPO analysis of gastric tissue. Treatment with the ISP-VT significantly reduced rectal temperature in yeast-induced hyperthermia in mice. Our results showed that the main mechanism ISP-VT-induced anti-inflammatory activity is by inhibition of COX-2. In conclusion, our results indicate that ISP-VT has potential as an anti-inflammatory and antipyretic therapeutic compound.
