Lung fibrosis negatively impacts on lung function in chronic asthma and is linked to the development of profibrotic macrophage phenotypes. Epidemiological studies have found that lung function benefits from increased consumption of fruit high in polyphenols. We investigated the effect of boysenberry consumption, in both therapeutic and prophylactic treatment strategies in a mouse model of chronic antigen-induced airway inflammation. Boysenberry consumption reduced collagen deposition and ameliorated tissue remodeling alongside an increase in the presence of CD68+CD206+arginase+ alternatively activated macrophages in the lung tissue...

Basement membranes (BMs) are highly specialized extracellular matrices (ECMs) that provide support and polarization cues for epithelial cells. Proper adhesion to the BM is pivotal in epithelial cell function and survival. Type IV collagens are the predominant components of all types of BMs, that form an irregular, polygonal lattice and serve as a scaffold for numerous other BM components and BM-associated cells. Mutations in the ubiquitous human BM components COL4A1 and COL4A2 cause a multisystem disorder involving nephropathy...

Solar ultraviolet (UV) irradiation is a primary cause of premature skin aging that is closely associated with the degradation of collagens caused by up-regulation of matrix metalloproteinases (MMPs) or a decrease in collagen synthesis. The phenolic veratric acid (VA, 3,4-dimethoxybenzoic acid) is one of the major benzoic acid derivatives from fruits, vegetables and medicinal mushrooms. VA has been reported to have anti-inflammatory, anti-oxidant and photo-protective effects. In this study, anti-photoaging effects were investigated through the photo-protective mechanisms of VA against UV irradiation in human dermal fibroblasts and the reconstructed human epidermal model...

Nobiletin, a bioactive polymethoxylated flavone isolated from citrus fruits, has been proven to prevent cancer and inflammation. Dietary flavonoids have been shown to reduce the risk of cardiovascular diseases (CVDs), and platelet activation plays a crucial role in CVDs. This study investigated the effect of nobiletin on platelet activation in vitro and in vivo. Nobiletin (10-30μM) inhibited collagen- and arachidonic acid-induced platelet aggregation in washed human platelets, but it did not inhibit platelet aggregation induced by other agonists such as thrombin and 9,11-dideoxy-11α,9α-epoxymethanoprostaglandin...
