Platelet-derived exosomes mediate platelet atherogenic interactions with
endothelial cells and monocytes. A new method for isolation of plasma
platelet-derived exosomes is described and used to examine effects of aging and
aspirin on exosome cargo proteins. Exosome secretion by purified platelets in
vitro did not increase after exposure to thrombin or collagen, as assessed by
exosome counts and quantification of the CD81 exosome marker. Thrombin and
collagen increased exosome content of ?-granule chemokines CXCL4 and CXCL7 and
cytoplasmic high-mobility group box 1 (HMGB1) protein, but not membrane platelet
glycoprotein VI (GPVI), with dependence on extracellular calcium. Aspirin
consumption significantly blocked thrombin- and collagen-induced increases in
exosome cargo levels of chemokines and HMGB1, without altering total exosome
secretion or GPVI cargo. Plasma platelet-derived exosomes, enriched by absorption
with mouse antihuman CD42b [platelet glycoprotein Ib (GPIb)] mAb, had sizes and
cargo protein contents similar to those of exosomes from purified platelets. The
plasma platelet-derived exosome number is lower and its chemokine and HMGB1
levels higher after age 65 yr. Aspirin consumption significantly suppressed cargo
protein levels of plasma platelet-derived exosomes without altering total levels
of exosomes. Cargo proteins of human plasma platelet-derived exosomes may biomark
platelet abnormalities and in vivo effects of drugs.- Goetzl, E. J., Goetzl, L.,
