The invention discloses a double-membrane independently wrapped
nano drug delivery system for regulating macrophages and platelets. The
nano drug delivery system comprises macrophage membrane coated nanoparticles and
platelet membrane coated nanoparticles, the macrophage membrane coated nanoparticles are used for adjusting macrophage immune response and loaded with a
Toll-like
receptor 7 (TLR7) inhibitor, the
platelet membrane coated nanoparticles are used for inhibiting abnormal activation of platelets and loaded with a
G protein coupled
receptor P2Y12 inhibitor, the TLR7 inhibitor comprises at least one of TJ-M2010-5,
hydroxychloroquine, Enpatron and IMO-8400, and the TLR7 inhibitor comprises at least one of TJ-M2010-5,
hydroxychloroquine, Enpatron and IMO-8400. The P2Y12 inhibitor is prepared from at least one of
ticagrelor,
clopidogrel,
prasugrel and
cangrelor. According to the double-membrane independently-wrapped
nano drug delivery system, drugs are efficiently delivered to related damaged cells of an
inflammation part by utilizing related
cell tropism of two
cell membranes,
immune disorder caused by macrophage and
platelet abnormality is inhibited, diseases induced by immune imbalance are treated, an
immune microenvironment is regulated and controlled, and the
drug delivery effect is improved. And a new direction is provided for treatment of immune diseases.
