Optimal control of receptor reinsertion in the low density lipoprotein endocytic cycle.
On the basis of this study, it is concluded that within physiological limits the minimum value for the mean capture time of LDL receptors by coated pits must be induced fundamentally by an optimal characterization of their insertion rate function. The corresponding steady-state surface aggregation patterns for the unbound receptors are consistent with experimental observations. The implications of the derived results for the estimation of the minimum physiological value for the referred mean capture time are also discussed.
