Summary: The study aimed to develop anti-inflammatory agents for human neutrophils. The most effective compounds inhibiting the generation of superoxide anions in neutrophils were identified through drug screening. Further research was conducted on these compounds, including PDE selective screening and molecular simulation experiments. The results showed that a new class of PDE4 inhibitors had potent neutrophil inactivation activity.

Summary: A natural lignan called meso-dihydroguaiaretic acid (MDGA) has been found to inhibit inflammatory responses in human neutrophils and reduce lung damage associated with acute respiratory distress syndrome (ARDS) in mice. This study suggests that MDGA has anti-inflammatory effects and free-radical scavenging activity, making it a potential lead for developing new therapeutics for ARDS.

Summary: In this study, a targeting peptide-conjugated chemiluminescent reporter (OFF) was developed to detect and visualize inflammatory diseases. The reporter was recognized by neutrophils and transported to inflamed tissues characterized by overexpressed superoxide anion (O2·-). The chemiluminescent probe specifically responded to O2·- and released photons (ON) for early detection and precise excision of micrometastatic lesions.

Summary: Study found that the chemotactic response of neutrophil granulocytes (NGs) to leukotriene B-4 (LTB4) is reduced in asthmatics, especially those with a Th1-high phenotype. NGs from asthmatic children treated with inhaled corticosteroids (ICS) migrated similarly to controls, except for Th1-high asthmatics whose NGs showed reduced and less directed migration. The altered receptor profile in ICS-treated and Th1-high asthmatics may explain the migration pattern.

Summary: A new lignan, 4'-methoxy-neotaiwanensol (1), and five known compounds (2-6) were isolated from Piper sarmentosum leaves. The structure elucidation was conducted by interpreting the spectral data, including NMR and HRESIMS. Compounds 4 and 5 are new natural products and their NMR data in methanol-d4 were reported for the first time. In vitro assays showed that compounds 1 and 3 exhibited better inhibitory effects on α-glucosidase compared to acarbose, and compounds 1 and 2 exhibited moderate antioxidant effects.

Summary: Rheumatoid arthritis (RA) is characterized by inflammation outbreak and joint destruction. Neutrophils play a crucial role in RA by releasing excess neutrophil extracellular traps (NETs), but preventing NETs formation is still challenging. In this study, a method using sivelestat-conjugated bovine serum albumin nanoparticles (BTST NPs) was established to selectively inhibit neutrophil elastase (NE) and prevent NETs production. Additionally, the BTST NPs were loaded with dexamethasone palmitate (DP) for synergistic treatment of RA. The results showed that DP/BTST NPs could effectively target inflamed neutrophils, hinder NETs generation, and improve RA symptoms.

Summary: This study investigates the role of MC4R in melanoma and the use of the selective antagonist ML in combination with vemurafenib. The results show that ML can inhibit melanoma cell proliferation and induce apoptosis through the inhibition of ERK1/2 phosphorylation and reduction of BCL-XL expression. The combination of vemurafenib and ML exhibits a synergistic effect in vitro and inhibits tumor growth in vivo without causing adverse effects.

Summary: Bitter taste receptors (T2Rs) are a type of G protein-coupled receptors that allow humans to detect aversive and toxic substances. This study characterized the functional properties of previously identified T2Rs in human cardiac tissues and their naturally occurring polymorphisms. The results showed differences in signaling among different T2R variants, and revealed a potential association between the T2R50 Tyr203 variant and cardiovascular disease.

Summary: This study demonstrates that Carfilzomib exhibits potent anti-tumor activity against esophageal squamous cell carcinoma (ESCC) by triggering mitochondrial apoptosis and reprogramming cellular metabolism. It has been identified that activating transcription factor 3 (ATF3) plays a crucial role as a cellular target in ESCC cells treated with Carfilzomib. Overexpression of ATF3 effectively counteracts the effects of Carfilzomib on ESCC cell proliferation, apoptosis, and metabolic reprogramming. Furthermore, ATF3 mediates the anti-tumor activity of Carfilzomib, suggesting its potential as a therapeutic agent for ESCC.
