Preparation of hemoglobin-free ghosts of erythrocytes and SO 4 = uptake measurement. Preparation of hemoglobin-free ghosts of erythrocytes and SO 4 = uptake measurement. However, the concept needs further optimization to become a routine drug delivery system. Fig. Composition of RBCs: RBCs include water (63%), lipids (0.5), glucose (0.8%), mineral (0.7%), non-haemoglobin protein (0.9%), meth haemoglo- bin (0.5%), and haemoglobin (33.67%), FIG. Hypotonic dilution was the first method investigated for the encapsulation of chemicals into erythrocytes and is the simplest and fastest. The mechanism by which liposome elicits its therapeutic action is by fusing the lipid bilayer with that of cell membrane thus leading to ejection of liposomes on to the targeted site. 7: SCHEMATIC REPRESENTATION OF HYPOTONIC DILUTION METHOD 8. Hence, this method is limited to mainly cell biological applications rather than drug delivery. Report. All three spin-labeled phospholipids initially incorporated into the outer leaflet of the membrane. In one of these approaches, the drug-loaded erythrocytes have been exposed to membrane stabilizing agents. The resealed erythrocyte is a cellular carrier have more advantage than other carrier system. The tonicity of the dialysis tube is restored by directly adding a certain amount of a hypertonic buffer to the surrounding medium. 1996; 71 (1): 479–486. 59. Resealed Erythrocytes as carriers for drugs: - Various bioactive agents encapsulated in erythrocytes are developed for the slow and sustained release in circulation to allow effective treatment of parasitic diseases.

The supernant was estimated for percent haemoglobin release analytically. RES targeting: In this review, the potential applications of erythrocytes in drug delivery have been highlighted. (adsbygoogle = window.adsbygoogle || []).push({}); About Authors: Varun Raj Vemula*1, Swathi Thakkalapally2, Chaitanya Kumari Bairi3 Lipid vesicles containing a drug can be directly fused to human erythrocytes, which lead to an exchange with a lipid-entrapped drug. As mentioned earlier, there are two major strategies in the delivery of drugs using erythrocytes as carriers which include intravenous slow drug release strategy and target gene delivery. Disadvantages include a need for a larger size of fused cells, thus making them amenable to RES clearance, adverse effects of fusogens, and unpredictable effects on cell resulting from the co- introduction of various components. The RBCs swell and pores appear on their membrane allowing the L-asparaginase to enter erythrocytes. The process is based on two sequential hypotonic dilutions of washed erythrocytes followed by concentration with a hemofilter and an isotonic resealing of the cells. Most drugs currently used in the clinical practice, can cross the red cell membrane by simple diffusion or by transport‐mediated mechanisms. 5: SCHEMATIC REPRESENTATION OF RBC’s.

Relatively easy to maintain plasma concentration with decrease in fluctuation in concentration. Biochem.1983; 5 (3): 149–157. Drugs like gentamycin, furamycin, adiramycin, inositol enzymes have been incorporated by this method. Each RBC contains about 280 million haemoglobin molecules which composed of protein called globin, containing four polypeptide chains, a ring like non-protein pigment called a heme, bound to each of the four chains. Resealed erythrocytes of asparaginase have shown good results in asparaginase dependent leukaemia. The other effective site for the destruction of the aged or abnormal erythrocytes is the macrophages of the RES including peritoneal macrophages, hepatic Kupffer cells and alveolar macrophages of the lung, peripheral blood monocytes, and vascular endothelial cells. There are mainly three ways for a drug to efflux out from the erythrocyte carriers: phagocytosis, diffusion through the membrane of the cells and using a specific transport system. There are mainly three ways for a drug to efflux out from the erythrocyte carriers: phagocytosis, diffusion through the membrane of the cells and using a specific transport system.

Some of the examples are: Glutaraldehyde: The treatment of drug loaded erythrocytes with glutaraldehyde increases the osmotic fragility, stability, sensitivity towards RES particularly suitable for organs like liver, spleen. The method of isolation involves collection of sample from the interest, then separating the plasma and finally resealing it. Mature RBCs have a simple structure and are elastic in nature their plasma membrane is strong and flexible so that they can squeeze through narrow capillaries without deformation. One of the most widely used carriers is erythrocytes which are non-immunogenic, non-pathogenic whose circulation can be controlled with time. R.A. Schlegel and M.C. The RBC’s are subjected to 2.2 KV current followed by addition of suspension. Various types of mammalian erythrocytes have been used for drug delivery, including erythrocytes of mice, cattle, pigs, dogs, sheep, goats, monke ys, chicken, rats, and rabbits.

The ceramic microspheres are also an emerging type which finds their application in grinding media. Different types of mammalian erythrocytes have been used for drug delivery,this includes erythrocytes from cattle, dogs, pigs, sheep, goats, monkeys, mice, chicken, rats, and rabbits etc. Hence, these carriers are called resealed erythrocytes. Easily biodegradable with lowest toxicity. 1. 1981; 78(5): 2786–2790. 1976; 65: 59–62. Third Order Targeting: refers to drug delivery specifically to the intracellular site of targeted cells e.g. This method is based on the increase in membrane permeability of erythrocytes when the cells are exposed to certain chemicals. Relatively small volumes of aqueous drug solution are added at the point of lysis. Nanoerythrosomes are vesicles formed by the extrusion of red blood cell ghosts and the average diameter is 0.1µm 22. In this review article, the potential applications of erythrocytes in drug delivery have been reviewed with a particular stress on the studies and laboratory experiences on successful erythrocyte loading and characterization of the different classes of biopharmaceuticals. Ideal Characteristics of Targeted Drug Delivery System: Target: It means specific organ or a cell or group of cells, which are treated in chronic or acute condition. Erythrocytes have been used as circulating depots for the sustained delivery of antineoplastics, antiparasitics, veterinary antiamoebics, vitamins, steroids, antibiotics and cardiovascular drugs. ASNase is an enzyme which hydrolyzes amino acid L-asparagine (ASN) to L-aspartic acid and ammonia. 1984;22: 137–146. D.J. The rate of diffusion depends upon the rate at which a particular molecule penetrates through a lipid by layer. *  antibody attachment to erythrocyte membrane to get specificity of action, Erythrosomes:These are specially engineered vesicular systems that are chemically cross-linked to human erythrocytes’ support upon which a lipid bilayer is coated. 8: SCHEMATIC REPRESENTATION OF HYPOTONIC DIALYSIS METHOD 8. A significant increase of the acidic form of sialidase, which is anchored to the membrane by a glycosylphosphatidylinositol bridge, was observed in erythrocyte resealed membranes. (Series) 1987; 67: 243–250. Mainly dialysis method is used to entrap the drug following its isotonic resealing. 1998; 28: 1–6. 71.

K. Kinosita, T.Y. RBCs lack nucleus and other organelles and can neither reproduce nor carry on extensive metabolic activities. 21. This process is followed by an influx of water to maintain osmotic equilibrium. Erythrocytes, also known as red blood cells, and have been extensively studied for their potential carrier capabilities for the delivery of drugs. C.A. Some of the most important advantages encouraging the use of erythrocytes in drug delivery include: [6-15]. Int J Pharm Sci Res 2017; 8(8):3242-51.doi: 10.13040/IJPSR.0975-8232.8(8).3242-51. Upon reinjection, the resealed erythrocytes work as slow circulating depots and thereby targeting the drugs to a reticulo-endothelial system (RES). 31. Example of active targeting is use of monoclonal antibody the treatment of cancer. The permeability of erythrocyte membrane increases upon exposure to polyene antibiotic such as amphotericin B. Danorubicin an antineoplastic agent can be delivered by this method. Such drug-loaded carrier erythrocytes are prepared simply by collecting blood samples from the organism of interest, separating erythrocytes from plasma, entrapping drug in the erythrocytes, and resealing the resultant … Passive Targeting: Accumulation of drug or drug carrier system in specific area of the body e.g. hours the erythrocytes were isolated, twice washed in excess volume of NaCl saline and used. Antagonization of organophosphorus intoxication by resealed erythrocytes containing a recombinant phosphodiestrase also has been reported. In patients of this condition, the bone marrow produces excess immature white blood cells, called lymphoblasts, which are unable to help the body fight infections. Due to gravitational force the supernatant layer is discarded and the detection point is considered when the boundary between the cell lines and supernatant disappears. Kulka, “Ultra microinjection of Macromolecules or Small Particles into Animal Cells,” J. Enzymes are widely used in clinical practice as replacement therapies to treat diseases associated with their deficiency (e.g., Gaucher’s disease, galactosuria), degradation of toxic compounds secondary to some kind of poisoning (cyanide, organophosphorus), and as drugs. Harris, and G.M. This is obtained by... 2. As carrier erythrocytes have long span they can be used as circulating depots for antitumor, antibiotics and cardiovascular drugs. Given that they are carriers of biological origin, encapsulated erythrocytes may present some inherent variations in their loading and characteristics compared to other carrier systems. The problems involved in the direct injection of enzymes into the body have been cited. The microinjection process involves culturing host eukaryotic cells in vitro. 1997; 59: 275–281. Thevarious candidates entrapped by thismethod include primaquine and related8–amino–quinolines, vinblastine, chlorpromazineand related phenothiazines,hydrocortisone, propranolol and tetracaine.
