Aberrant activation of the nucleotide-binding domain and leucine-rich repeat related (NLR) family, pyrin domain containing 3 (NLRP3) inflammasome drives the development of many complex inflammatory diseases, such as obesity, Alzheimer’s disease, and atherosclerosis. However, no medications specifically targeting the NLRP3 inflammasome have become clinically available. Therefore, we aim to identify new inhibitors of the NLRP3 inflammasome in this study. Methods: Vesicle-like nanoparticles (VLNs) were extracted from garlic chives and other Allium vegetables and their effects on the NLRP3 inflammasome were evaluated in primary macrophages. After garlic chive-derived VLNs (GC-VLNs) were found to exhibit potent anti-NLRP3 inflammasome activity in cell culture, …

Honey has been used as a nutrient, an ointment, and a medicine worldwide for many centuries. Modern research has demonstrated that honey has many medicinal properties, reflected in its anti-microbial, anti-oxidant, and anti-inflammatory bioactivities. Honey is composed of sugars, water and a myriad of minor components, including minerals, vitamins, proteins and polyphenols. Here, we report a new bioactive component‒vesicle-like nanoparticles‒in honey (H-VLNs). These HVLNs are membrane-bound nano-scale particles that contain lipids, proteins and small-sized RNAs. The presence of plant-originated plasma transmembrane proteins and plasma membrane-associated proteins suggests the potential vesicle-like nature of these particles. H-VLNs impede the formation and activation …


Inhibitory Effects Of Shiitake-Derived Exosome-Like Nanoparticles On Nlrp3 Inflammasome Activation, Yizhu Lu Aug 2019

The NLRP3 inflammasome is a critical mediator of inflammation and consists of the sensor NOD-like receptor family, pyrin domain containing 3 (NLRP3), the adaptor apoptotic speck protein containing a caspase recruitment domain (ASC), and the effector caspase-1. Dysregulated or excessive activation of the NLRP3 inflammasome contributes to pathogenesis of diverse inflammatory diseases such as Type 2 diabetes and atherosclerosis. Therefore, the NLRP3 inflammasome is a promising therapeutic target for treating these diseases. Extracellular vesicles (EVs) are membrane-enclosed tiny particles released by almost any type of cells and they are involved in the intercellular communication by transferring their cargos including RNAs, …

Adipose tissue expansion is accompanied by infiltration and accumulation of pro-inflammatory macrophages, which links obesity to pathologic conditions such as type 2 diabetes. However, little is known regarding the role of pro-inflammatory adipose tissue remodeling in the thermogenic activation of brown/beige fat. Here, we investigated the effect of pattern recognition receptors (PRR) activation in macrophages, especially the toll-like receptor 4 (TLR4) and Nod-like receptor 3 (NLRP3), on white adipocyte browning. We report that TLR4 activation by lipopolysaccharide repressed white adipocyte browning in response to β3-adrenergic receptor activation and caused ROS production and mitochondrial dysfunction, while genetic deletion of TLR4 protected …

Chronic, low-grade inflammation during obesity is associated with the development of metabolic dysfunction. The NLRP3 inflammasome is assembled in response to cellular stressors and leads to cytotoxic cytokines IL-1β and IL-18 production, which implicates the NLRP3 inflammasome in inflammatory conditions, including type 2 diabetes. Tocotrienols are antioxidant and anti-inflammatory forms of vitamin E. Delta-tocotrienol (dT3) displays NF-κB inhibitory and anti-oxidant abilities, and is easily isolated from the Annatto plant. My primary aim was to determine whether dT3 inhibits NLRP3 inflammasome activation and to compare the extent to which dT3 inhibits NLRP3 inflammasome with other tocotrienol forms, i.e. alpha-tocotrienol (aT3) and …
