The effect of layers of high tunnel covering and soil mulching on tomato fruit quality.

Background: High tunnels (HT) and plastic mulch can increase yield, extend growing seasons, protect plants from harsh weather conditions, and produce more marketable and attractive tomatoes.

The P2X7 receptor (P2X7R)-specific antagonist A804598 inhibits inflammatory reaction in human fibroblast-like synoviocytes.

Activation of the P2X7 receptor (P2X7R) has been found to increase expression of tumor necrosis factor-α (TNF-α) in the joints and synovial lining of patients with rheumatoid arthritis (RA). Increased expression of TNF-α promotes joint destruction through deterioration of type II collagen by matrix metalloproteinases (MMPs), expression of proinflammatory cytokines, oxidative stress, and activation of cellular signaling pathways. In the present study, we exposed fibroblast-like synoviocytes (FLSs) to TNF-α in the presence and absence of the P2X7R antagonist A804598.
