Evidence of tricellulin expression by immune cells, particularly microglia

► The tight junction protein tricellulin is expressed in epithelial and non-epithelial cells. ► Gastric epithelium exhibits tricellulin at bi- and tricellular tight junctions. ► Tricellulin expression is detected in macrophages throughout the gastric mucosa. ► Microglia, the brain resident immune cells, express tricellulin mRNA and protein.
