Figure 6.

Effect of temperature on the transport of ¹²⁵I-LDL (A) and sucrose (B) from apical to basal surfaces. Specific transport of LDL was performed as described in Fig. 4, legend. Transport of [¹⁴C]sucrose was expressed as the percentage of radioactivity crossing the brain capillary EC monolayer from the apical to the abluminal surfaces. ¹²⁵I-LDL and sucrose transport were performed both at 37° (□, ○) and 4°C (▪, •). The data represent the means of three filters, and the curves are representative of two series of independent experiments.
