The Anitschkow Model Reconsidered: From Dietary Cholesterol to Disrupted Lipid Homeokinesis in Atherosclerosis
Mykola Iabluchanskyi and Pavlo Garkaviy Abstract The classical cholesterol‑fed rabbit model described by Nikolai Anitschkow has long been interpreted primarily as an experiment in harmful dietary cholesterol. In this narrow reading, atherosclerosis appears mainly as the vascular consequence of excessive intake. A closer analysis, however, suggests a richer meaning. The model shows what happens when an organism is driven beyond the range in which lipid burden can still be processed, redistributed, and cleared without long‑lasting disturbance of internal regulation. In this sense, the Anitschkow rabbit is less a model of “bad diet” and more a model of disrupted lipid homeokinesis and progressive lipid accumulation with superimposed inflammation. This article argues that the true conceptual value of the model lies in its demonstration of a transition from externally imposed metabolic overload to an internally sustained atherogenic state. Reinterpreted in this way, the model ali...
