The predominant mechanism involves Tf/TfR1-mediated endocytosis, where transferrin-bound Fe 3+ binds to TfR1 on endothelial cells, is internalized into endosomes, acidified, and subsequently released into the cytosol via DMT1-mediated transport
Because ONL belongs to the photoreceptor cell layer, it often experiences a decrease in thickness and a decrease in the number of rod and cone cells when damaged, leading to problems such as decreased visual sensitivity, loss of field of view, and color vision abnormalities (Figure 1)
Can taking a daily supplement prevent cognitive decline in those with early stages of the disease
Oral administration (capsule or lozenge) is more convenient and may be appropriate when the primary goal is GI support, since BPC-157 is remarkably stable in gastric juice
