    摘要: A pharmaceutical composition includes a silicified cell or fraction thereof, a cationic layer disposed on at least a portion of the surface of the silicified cell or fraction thereof, and an immunomodulatory moiety bound to at least a portion of the cationic layer. Alternatively, the pharmaceutical composition includes a silicified cell or fraction thereof, a cationic layer disposed on at least a portion of the surface of the silicified cell or fraction thereof, an anionic layer disposed on at least a portion of the cationic layer, and an immunomodulatory moiety bound to at least a portion of the anionic layer.
