The study aimed at quantitative analysis of expression involving markers of mast cells (tryptase), monocytes/macrophages (CD68 molecule) and dendritic cells (S100 protein) in gallbladder mucosa with acute and chronic calculous cholecystitis.

Routinely prepared tissue material from the patients with acute (ACC) (n = 16) and chronic calculous cholecystitis (CCC) (n = 55) was evaluated. Three cellular markers were localized by immunocytochemistry. Their expression was quantified using spatial visualization technique.

The expression of tryptase was similar in acute and chronic cholecystitis. CD68 expression in ACC was significantly higher than in the CCC group. Expression of S100 protein was significantly higher in CCC as compared to the ACC group. No significant correlations were disclosed between expression of studied markers and grading in the gallbladder wall. A weak negative correlation was noted between expression of CD68 and number of gallstones in the CCC group.

The spatial visualization technique allowed for a credible quantitative evaluation of expression involving markers of mast cells (MCs), monocytes/macrophages (Mo/Ma) and dendritic cells (DCs) in gallbladder mucosa with ACC and CCC. For the first time mucosal expression of S100 protein-positive DCs was evaluated in calculous cholecystitis. The results point to distinct functions of studied cell types in the non-specific immune response in calculous cholecystitis.
