Abstract

Due to their abundant ubiquitous presence, rapid uptake and increased requirement in neoplastic tissue, the delivery of the iron carrier macromolecules transferrin (Tf) and lactoferrin (Lf) into mammalian cells is the subject of intense interest for delivery of drugs and other target molecules into cells. Utilizing exosomes obtained from cells of diverse origin we confirmed the presence of the multifunctional protein glyceraldehyde-3-phosphate dehydrogenase (GAPDH) which has recently been characterized as a Tf and Lf receptor. Using a combination of biochemical, biophysical and imaging based methodologies, we demonstrate that GAPDH present in exosomes captures Tf and Lf and subsequently effectively delivers these proteins into mammalian cells. Exosome vesicles prepared had a size of 51.2 ± 23.7 nm. They were found to be stable in suspension with a zeta potential (ζ-potential) of -28.16 ± 1.15 mV. Loading of Tf/Lf did not significantly affect ζ-potential of the exosomes. The carrier protein loaded exosomes were able to enhance the delivery of Tf/Lf by 2 to 3 fold in a diverse panel of cell types. Ninety percent of the internalized cargo via this route was found to be specifically delivered into late endosome and lysosomes. We also found exosomes to be tunable nano vehicles for cargo delivery by varying the amount of GAPDH associated with exosome. The current study opens a new avenue of research for efficient delivery of these vital iron carriers into cells employing exosomes a…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
