Figure 1From: Surface aggregation patterns of LDL receptors near coated pits III: potential effects of combined retrograde membrane flow-diffusion and a polarized-insertion mechanism The geometry of the model. a) A circular trap of radius a (the coated pit) is encircled by an annulus of radius b (the reference region Ω associated with a coated pit). LDL receptors originally inserted at a point (r, θ) inside the reference annulus Ω, move afterwards by convection and diffusion until they are trapped in coated pits. b) Receptor insertion occurs according to a partitioned insertion rate function S rθ(c, p, q, m, α), which sorts receptors at distinct rates S c rθ m , α , S p rθ m , α and S q rθ m , α linked respectively to the disjoint regions Ω c , Ω p and Ω q .Back to article page
