The endothelial cell monolayer lining the vessel wall forms a size-selective, semi-permeable barrier between the blood and tissue that must be crossed by blood borne therapeutic agents to reach diseased extravascular tissue. Nanoparticles engineered to carry drugs present an opportunity to enhance the specificity and efficacy of drug delivery. Therefore, an understanding of how these engineered nanoparticles are transported across the vessel wall will help us to more fully exploit this powerful therapeutic technology. Vascular endothelial cells are rich in caveolae, cell surface invaginations 50-100 nm in diameter that mediate endocytosis of lipids, proteins, and viruses. Caveolar invaginations pinch off to form intracellular vesicles that can transport cargo across the cell and release the cargo into the extravascular space via exocytosis. Here, we will review the current concepts and state of development for delivering engineered nanoparticles across the endothelium via the caveolae-mediated pathway.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 February 2017.
All research outputs
#8,142,437
of 24,417,958 outputs
Outputs from IUBMB Life
#404
of 1,551 outputs
Outputs of similar age
#43,693
of 120,386 outputs
Outputs of similar age from IUBMB Life
#8
of 16 outputs
Altmetric has tracked 24,417,958 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,551 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 120,386 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
