Codocytes, also known as target cells, are red blood cells that have the appearance of a shooting target with a bullseye. In optical microscopy these cells appear to have a dark center (a central, hemoglobinized area) surrounded by a white ring (an area of relative pallor), followed by dark outer (peripheral) second ring containing a band of ...
By understanding the method in which substances move along neurons or microtubules it is possible to target specific pathways for disease. Currently, many drug companies are aiming to utilize the trajectory of intracellular transport mechanisms to deliver drugs to localized regions and target cells without harming healthy neighboring cells.
Cell Surface Peptides provide one way to introduce drug delivery into a target cell. [16] This method is accomplished by the peptide binding to a target cells surface receptors, in a way that bypasses immune defenses that would otherwise compromise a slower delivery, without causing harm to the host.
An early example was the use of sendai virus to fuse pre-loaded red blood cell ghosts with the plasma membrane of target cells . [58] A variation on this technique utilized expression of influenza hemagglutinin (HA) at the target cell membrane, which then binds sialic acid residues on the red blood cell surface to induce fusion . [59]
Immunoliposome therapy is a targeted drug delivery method that involves the use of liposomes (artificial lipid bilayer vesicles) coupled with monoclonal antibodies to deliver therapeutic agents to specific sites or tissues in the body. [1]
Although the target cell selection must be highly accurate, the degree of specificity that the neural connectivity achieves varies based on the neuronal circuitry system. [1] The target selection process of an axon to develop synaptic connections with specific cells can be broken down into multiple stages that are not necessarily confined to ...

Cellular immunity protects the body through: T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
