    Abstract Objectives: Blood-processing techniques and preservation conditions cause storage lesions, possibly leading to adverse outcomes after transfusion. The authors investigated the metabolic changes and deformability of red blood cells (RBCs) during storage and determined the effect of storage lesions on circulating RBCs during cardiac surgery.
    Design: Prospective study.
    Setting: Tertiary care center affiliated with a university hospital.
    Participants: Adults who underwent elective cardiac surgery requiring cardiopulmonary bypass.
    Interventions: The authors collected aliquots of autologous and irradiated allogeneic RBCs and blood samples from seven patients who received autologous whole blood and nine patients who received irradiated allogeneic RBCs before incision (baseline), at the start and end of cardiopulmonary bypass, and at completion of surgery.
    Measurements and main results: The authors analyzed RBC deformability, erythrocyte indices, and density distribution to evaluate blood banking-induced alterations of autologous and allogeneic RBCs and changes in circulating RBCs in recipients, after blood transfusion. Time-dependent biochemical changes and significant decreases in deformability during storage occurred in both groups; however, homologous RBCs had significantly lower deformability than autologous RBCs. Trends in mean corpuscular volume and mean corpuscular hemoglobin concentration differed in both groups. In the homologous transfusion group, during cardiac surgery, RBC deformability, mean corpuscular volume, and mean corpuscular hemoglobin concentration showed significant changes compared with baseline values, and a greater number of denser subpopulations was observed at surgery completion.
    Conclusions: Blood-processing techniques contribute to storage lesions, suggesting that transfusion of autologous whole blood, rather than allogeneic RBCs, could maintain the ability of circulating RBCs to deform and lead to potentially better transfusion outcomes.

    Abstract The tumor-elicited inflammation is closely related to tumor microenvironment during tumor progression. S100A8, an endogenous ligand of Toll-like receptor 4 (TLR4), is known as a key molecule in the tumor microenvironment and premetastatic niche formation. We firstly generated a novel multivalent S100A8 competitive inhibitory peptide (divalent peptide3A5) against TLR4/MD-2, using the alanine scanning. Divalent peptide3A5 suppressed S100A8-mediated interleukin-8 and vascular endothelial growth factor production in human colorectal tumor SW480 cells. Using SW480-transplanted xenograft models, divalent peptide3A5 suppressed tumor progression in a dose-dependent manner. We demonstrated that combination therapy with divalent peptide3A5 and bevacizumab synergistically suppressed tumor growth in SW480 xenograft models. Using syngeneic mouse models, we found that divalent peptide3A5 improved the efficacy of anti-programmed death (PD)1 antibody, and lung metastasis. In addition, by using multivalent peptide library screening based on peptide3A5, we then isolated two more candidates; divalent ILVIK, and tetravalent ILVIK. Of note, multivalent ILVIK, but not monovalent ILVIK showed competitive inhibitory activity against TLR4/MD-2 complex, and anti-tumoral activity in SW480 xenograft models. As most tumor cells including SW480 cells also express TLR4, S100A8 inhibitory peptides would target both the tumor microenvironment and tumor cells. Thus, multivalent S100A8 inhibitory peptides would provide new pharmaceutical options for aggressive cancers.

    Abstract Purpose of review: The article summarizes new insights into the molecular mechanisms for the maintenance and regulation of the asymmetric distribution of phospholipids in human erythrocyte membranes. We focus on phosphatidylserine, which is primarily found in the inner leaflet of the membrane lipid bilayer under low Ca conditions (<1 μmol/l) and is exposed to the outer leaflet under elevated Ca concentrations (>1 μmol/l), when cells become senescent. Clarification of the molecular basis of phosphatidylserine flipping and scrambling is important for addressing long-standing questions regarding phosphatidylserine functions.
    Recent findings: ATP11C, a P-IV ATPase, has been identified as a major flippase in analyses of patient erythrocytes with a 90% reduction in flippase activity. Phospholipid scramblase 1 (PLSCR1) has been defined as a Ca-activated scramblase that is completely suppressed by membrane cholesterol under low Ca concentrations.
    Summary: For survival, phosphatidylserine surface exposure is prevented by cholesterol-mediated suppression of PLSCR1 under low Ca concentrations, irrespective of flipping by ATP11C. In senescent erythrocytes, PLSCR1 is activated by elevated Ca, resulting in phosphatidylserine exposure, allowing macrophage phagocytosis. These recent molecular findings establish the importance of the maintenance and regulation of phosphatidylserine distribution for both the survival and death of human erythrocytes.

    Abstract Mature human erythrocytes circulate in blood for approximately 120 days, and senescent erythrocytes are removed by splenic macrophages. During this process, the cell membranes of senescent erythrocytes express phosphatidylserine, which is recognized as a signal for phagocytosis by macrophages. However, the mechanisms underlying phosphatidylserine exposure in senescent erythrocytes remain unclear. To clarify these mechanisms, we isolated senescent erythrocytes using density gradient centrifugation and applied fluorescence-labelled lipids to investigate the flippase and scramblase activities. Senescent erythrocytes showed a decrease in flippase activity but not scramblase activity. Intracellular ATP and K

    Abstract The red blood cells (RBCs) of vertebrates have evolved into two basic shapes, with nucleated nonmammalian RBCs having a biconvex ellipsoidal shape and anuclear mammalian RBCs having a biconcave disk shape. In contrast, camelid RBCs are flat ellipsoids with reduced membrane deformability, suggesting altered membrane skeletal organization. However, the mechanisms responsible for their elliptocytic shape and reduced deformability have not been determined. We here showed that in alpaca RBCs, protein 4.1R, a major component of the membrane skeleton, contains an alternatively spliced exon 14-derived cassette (e14) not observed in the highly conserved 80 kDa 4.1R of other highly deformable biconcave mammalian RBCs. The inclusion of this exon, along with the preceding unordered proline- and glutamic acid-rich peptide (PE), results in a larger and unique 90 kDa camelid 4.1R. Human 4.1R containing e14 and PE, but not PE alone, showed markedly increased ability to form a spectrin-actin-4.1R ternary complex in viscosity assays. A similar facilitated ternary complex was formed by human 4.1R possessing a duplication of the spectrin-actin-binding domain, one of the mutations known to cause human hereditary elliptocytosis. The e14- and PE-containing mutant also exhibited an increased binding affinity to β-spectrin compared with WT 4.1R. Taken together, these findings indicate that 4.1R protein with the e14 cassette results in the formation and maintenance of a hyperstable membrane skeleton, resulting in rigid red ellipsoidal cells in camelid species, and suggest that membrane structure is evolutionarily regulated by alternative splicing of exons in the 4.1R gene.

    Abstract Distribution of phosphatidylserine (PS) in the erythrocyte membrane is essential for its activity. Flippase transports phospholipids from the outer to the inner leaflet of the lipid bilayer and maintains asymmetric distribution of phospholipids in the plasma membrane. ATP11C, a flippase, catalyzes PS flipping at the plasma membrane in association with cell cycle control protein 50A (CDC50A). ATP11C T418 N mutation causes 90% decrease in erythrocyte PS-flippase activity. However, the mechanism of the activity reduction remains unknown. To study the endogenous expression of ATP11C in erythrocytes, we produced a monoclonal antibody against human ATP11C. Immunoblotting analyses with this antibody revealed the absence of ATP11C in erythrocyte membranes derived from a patient with the T418 N mutation. Transiently expressed ATP11C wild-type in cultured cells localized in the cell membranes in the presence of CDC50A. Contrastingly, ATP11C T418 N mutants stacked at the endoplasmic reticulum (ER) even in the presence of CDC50A, suggesting improper intracellular trafficking. Expression of the T418 N mutant in cultured cells was lower than that in the wild-type. However, reduced expression of the T418 N mutant was partially restored by treatment with proteasome inhibitors, suggesting ER-associated degradation of the mutant protein. Cells expressing T418 N did not show flippase activity at the plasma membrane. These data show that the loss of PS-flippase activity in erythrocytes carrying ATP11C T418 N mutation is due to impaired enzymatic activity, improper membrane trafficking, and increased proteasome degradation.

    Abstract Objectives: During cardiac surgery, circulating red blood cells (RBCs) are at risk of exposure to environmental factors during extracorporeal circulation and transfusion of stored RBCs. For this study, the authors observed morphological differences, deformability, density distribution, and erythrocyte indices of RBCs during cardiac surgery with cardiopulmonary bypass (CPB).
    Design: Prospective study.
    Setting: Tertiary care center affiliated with a university hospital.
    Participants: Adults who underwent elective cardiac surgery requiring CPB.
    Interventions: Blood samples were obtained from 13 patients before incision (baseline), at initiation of CPB, after separation from CPB, and at completion of surgery.
    Measurements and main results: The morphological index (MI) in RBCs using light microscopy and the maximum deformability index (DImax) using an ektacytometer were evaluated. In addition, the fractionation of RBCs and erythrocyte indices were measured. The MI at initiation of CPB was significantly higher without blood transfusion compared with baseline, although the DImax did not significantly decrease simultaneously. The DImax after separation from CPB and at completion of surgery were significantly lower than that at baseline. This lowered DImax was accompanied by a significantly reduced mean corpuscular volume and elevated mean corpuscular hemoglobin concentration compared with baseline. Dense RBC subpopulations increased after initiating CPB. The MI after separation from CPB and at completion of surgery partially recovered. Administered stored RBCs showed a high MI and the lowest DImax.
    Conclusions: Morphological changes at initiation of CPB are considered potentially reversible transformations without loss of the membrane surface area and do not have a significant effect on the DImax. A decrease in deformability likely is due to transfusion of stored RBCs.
