Capillary permeability to plasma proteins is a critical factor in regulating tissue-fluid balance. The endothelial cell monolayer lining the vessel wall is a porous (semipermeable) membrane through which fluid and solutes arFacet-Joints 发表于 2025-3-26 06:22:20

Karl Friedrich Bohler,Tobias Franzheld M.A.er, a protein therapeutic may also be seen as foreign. The result of being perceived as foreign can be benign, neutralize the activity of the therapeutic, or generate an adverse physiological response that may even be lethal. The protein may be intrinsically foreign because it has been obtained from确定方向 发表于 2025-3-26 17:19:21
Protein Uptake and Cytoplasmic Access in Animal Cells ways of delivering drugs into cells—for instance, with the purpose of irreversibly inhibiting the protein synthesis machinery of cancer cells—mechanisms by which various protein ligands are internalized by cells and subsequently translocated across the membrane of intracellular compartments are coming into focus.
