More intestinal cells than thought can absorb larger particles

Scientists discovered that enterocytes play a significant role in absorbing relatively large particles, challenging conventional wisdom and offering new avenues for increasing the absorption of medicines taken by mouth. The study found that between 10-50% of spheres were absorbed via endocytosis in cells called enterocytes.
