ABSTRACT
The formation of cholesterol gallstones is a very complex and polygenic disorder that involves an alteration of the secretion of bile lipids, cholesterol crystallization, important immunological reactions in the gallbladder tissue, formation of biliary sludge composed of mucin, and inadequate gallbladder motility. The search for a therapeutic target is oriented towards decreasing bile secretion and intestinal absorption of cholesterol, in which Niemann-Pick C1L1 (NPC1L1) proteins play an important role. In basic and clinical studies, regulating the expression of these proteins can reduce intestinal, liver, plasma and bile cholesterol levels, a therapeutic effect that would be useful not only for treating the disease, but to prevent it, given the large quantity of risk factors. We discuss these effects in this review and propose NPC1L1 proteins as future therapeutic targets of cholesterol gallstones disease.
