Abstract
Granulocyte immunofluorescence and granulocyte agglutination tests are standard methods for detecting human neutrophil antigen (HNA) antibodies (Abs); however, these require a typed panel of neutrophils, which can be time-consuming to develop, and it remains difficult to determine antibody specificity in some cases. We established and evaluated four detection systems for HNA-1a Abs based on an HNA-1a-expressing cell line (KY cells) and antigen capture. We additionally evaluated a commercial solid-phase system. Eleven HNA-1a antibody-positive samples, including the World Health Organization Reference Reagent, and 40 serum samples derived from male blood donors were used as positive and negative control samples, respectively. Although specificity was >0.90 in all systems evaluated, the sensitivity varied among the systems. The KY cell-based monoclonal antibody specific immobilisation of granulocyte antigens (KY-MAIGA) system using certain, but not all, monoclonal Abs, and the solid-phase system revealed higher sensitivity than other systems. In conclusion, the KY-MAIGA and commercial solid-phase systems were superior in terms of specific and sensitive detection of HNA-1a Abs.

Abstract
Autoimmune neutropenia of infancy (AIN), also called primary autoimmune neutropenia, is a disease in which antibodies recognize membrane antigens of neutrophils, mostly located on immunoglobulin G (IgG) Fc receptor type 3b (FcγIIIb receptor), causing their peripheral destruction. It is the most frequent type of neutropenia in children under 3-4 years of age and in most cases shows a benign, self-limited course. The diagnosis is based on evidence of indirect antineutrophil antibodies, whose detection frequently remains difficult. In this review we have analyzed the literature regarding AIN and present our personal experience in diagnosis and management.

Abstract
BACKGROUND AND OBJECTIVES Noninfectious and nonhaemolytic transfusion reactions are the most common type of transfusion reactions. Several new tests have been made, helping diagnosis and understanding of their pathogenesis. This manuscript provides a review of the literature on currently available tests in association with the approach in Japan. MATERIALS & METHODS Primarily by using key words, more than 100 pertinent articles in the Medline database were identified and reviewed. RESULTS Numbers of laboratory tests are available including those for plasma protein levels, plasma protein antibodies, leucocyte and platelet antibodies, serum N-terminal-pro-brain natriuretic peptide levels, serum tryptase levels and genetic microchimerism. Cross-match tests, such as basophil activation test and neutrophil activation test, are also available to determine a causal relationship between the reaction and transfusion. CONCLUSIONS Several tests should help to confirm diagnosis and determine causal relationship between adverse reactions and transfusion and to gain an insight into the mechanism of the reaction in some cases, although some of the recently developed tests have not been completely validated.

Abstract
Since 2000, Quality Assurance (QA) exercises for the detection and identification of granulocyte antibodies and DNA typing for human neutrophil antigens (HNA) have been distributed within the International Granulocyte Immunobiology Workshops, which are linked to International Society of Blood Transfusion. The exercises were standardised at the outset to enable laboratory performance to be monitored. Between 2000 and 2012, nine exercises were distributed to 20 laboratories. Overall, 45 examples of 42 unique samples containing defined granulocyte reactive antibodies were distributed for serological analysis together with 20 samples for HNA genotyping. The level of satisfactory serological performance was initially set at 50% and later increased to 70%, while the 'cut-off' for HNA genotyping was set at 100% after 2008. Failure to achieve the minimum score in the QA exercises in consecutive years resulted in temporary exclusion. In 2000, the 15 participating laboratories had a mean score of 56.1% for serological analysis and 13 laboratories attempted HNA-1a and -1b genotyping, while 11 attempted HNA-1c typing. Steady improvements in proficiency for serological testing and HNA typing occurred in subsequent exercises. In 2012, the mean score for serology was 88.5% and 12/13 laboratories scored 100% for HNA-1a, -1b, -1c, -3a, -3b, -4a, -4bw, -5a and -5bw genotyping. These QA exercises have provided an invaluable tool to monitor and improve the standard of granulocyte immunology investigations for participating laboratories, thereby enhancing performance for both clinical investigations and donor screening programmes to reduce the incidence of TRALI.

Abstract
BACKGROUND HNA-3 is a diallellic system located on choline transporter-like protein 2 (CTL2), defined by a polymorphism at Amino Acid 154. HNA-3a antibodies are of clinical importance in transfusion-related acute lung injury but antibody detection requires labor-intensive granulocyte isolation from HNA-typed donors and the use of techniques such as the granulocyte agglutination test or granulocyte immunofluorescence test. Also, there is no commercial test for detection of HNA-3 antibodies. STUDY DESIGN AND METHODS HEK293 cells were transfected to generate stable cell lines expressing CTL2 fragments (Amino Acids 55-230) and full-length membrane bound CTL2 with HNA-3a and -3b epitopes. Soluble fragments were used in enzyme-linked immunosorbent assays to detect HNA-3 antibodies. The cell lines expressing full-length proteins were trypsin treated to remove HLA antigens and frozen at -80°C. Thawed cells were then used to detect HNA-3 antibodies by flow cytometry. RESULTS Glycosylated and soluble CTL2 fragments were correctly recognized by 15 of 31 anti-HNA-3a sera and by both available anti-HNA-3b sera. Twenty-one anti-HLA sera reacted variably with untreated cell lines expressing full-length CTL2. After trypsin treatment of the cell lines, reactivity with HLA antisera was abrogated and all 31 anti-HNA-3a and two anti-HNA-3b sera bound to the corresponding cell line. CONCLUSION Whereas soluble, glycosylated CTL2 fragments cannot be used for the detection of HNA-3 antibodies, the HEK293 cells expressing full-length CTL2 proteins were useful in the detection of HNA-3 antibodies even in the presence of HLA antibodies. Moreover, the cell lines can be stored for at least 6 months before use.

Abstract
BACKGROUND AND OBJECTIVES Severe transfusion-related acute lung injury (TRALI) events have been linked to donor-derived neutrophil antibodies. The journey to developing mass donor neutrophil antibody screening platforms is challenged by the fragility of neutrophils and their unique-specific antigenic characteristics. MATERIAL AND METHODS This article critically evaluates the capabilities and potential of five emerging antibody screening platforms designed to detect neutrophil reactive antibodies relevant to TRALI. They are compared with established neutrophil serological methods. RESULTS Data from two recombinant antigen platforms and a method using human neutrophil antigens-expressing KY cells indicated high specificity. Two mixed cellular flow cytometric assays have the advantage of presenting native conformation of the human polymorphonuclear neutrophil antigenic epitopes. CONCLUSIONS To date, the number and specificity of test sera applied to each platform is small. This needs to be substantially increased and further rigorous serological evaluation is yet needed to compare the sensitivity and specificity limits of each new platform with classical methods. With a limited world supply of TRALI-relevant test sera, a collaborative effort of laboratories with neutrophil and TRALI investigation expertise is required.

Abstract
There is an international need for a large-scale human neutrophils antigen (HNA) antibody screening platform to minimize the risk of antibody-mediated transfusion-related acute lung injury. However, sourcing a substantial, reliable source of HNA, as well as the scarcity of well-characterized HNA antisera for validating new screening platforms, remain as major obstacles. This short communication presents an improved protocol for the effective use of HNA-expressing KY cells as a screening platform using eight well-characterized HNA antisera of a single defined specificity.

Abstract
Antibodies against human platelet antigens (HPAs) play important roles in thrombocytopenia. In Japan, HPA-4b antibody is frequently responsible for HPA-related neonatal alloimmune thrombocytopenia. A highly sensitive assay using platelets has been developed for the detection of antibodies against HPAs. However, it is difficult to obtain the platelets expressing specific HPAs required for the assay. Therefore, an alternative method not requiring platelets would be helpful to detect antibodies against HPAs. Glycoprotein IIIa (GPIIIa) cDNA encoding HPA-4b was individually co-transduced with that of wild-type GPIIb in K562 cells, which is a non-adherent cell line, using a retroviral vector. The expression of transgene products in cultured cells were observed for over 6 months. Next, to evaluating the sensitivity and specificity of this cell line panel, we performed monoclonal antibody-specific immobilization of platelet antigens (MAIPA) assay with a serum previously identified by another method. All HPA-4b antibodies in serum samples were positive, and all serum samples, including normal serum and serum containing HLA antibodies were negative. No difference was observed in the specificity and sensitivity between our method and conventional MAIPA using platelets. The present results indicate that this established cell line panel permits highly sensitive detection of specific antibodies against HPA-4b.

Abstract
BACKGROUND Granulocyte antibodies have been implicated in allo- and autoimmune neutropenia and in transfusion reactions. STUDY DESIGN AND METHODS Fifty-one sera from suspected alloimmune neutropenia or transfusion-related acute lung injury (TRALI) and 40 sera from suspected autoimmune neutropenia were tested for granulocyte antibodies using LABScreen MULTI (One Lambda, Inc.), compared with classical tests (flow cytometry [FC] and granulocyte agglutination [GAT] followed by monoclonal antibody-specific immobilization of granulocyte antigens [MAIGA]). RESULTS In alloimmune situations, 48 sera were concordant (94%), two sera positive for HNA with LABScreen MULTI were negative by FC/GAT and/or MAIGA, and one serum sample negative for HNA with LABScreen MULTI was positive by classical tests. In autoimmune neutropenia, 30 sera were concordant (75%), four sera positive for HNA with LABScreen MULTI were negative by FC/GAT and/or MAIGA, and six sera negative for HNA with LABScreen MULTI were positive by FC/GAT and/or MAIGA. For detection of autoantibodies, the LABScreen MULTI was less concordant. However, with the exception of one case, the discrepancies were observed in sera that did not show a clear specificity. CONCLUSIONS LABScreen MULTI correlated well with our classical methods for HNA-1 and HNA-2a antibody screening. It can be used for screening blood donors or patients suspected of TRALI, but GAT is still needed for HNA-3a antibody screening.

Abstract
Nonhemolytic transfusion reactions (NHTRs) are the most common transfusion reactions and include transfusion-related acute lung injury (TRALI) and allergic and febrile reactions. White blood cell (WBC) antibodies (Abs) against human leukocyte antigen (HLA) and human neutrophil antigen (HNA) in blood components are frequently implicated in NHTRs, especially in TRALI. Recently, we established a five-cell-lineage immunofluorescence test, a modified granulocyte immunofluorescence test, and a panel of cell lines stably expressing HNAs for efficient detection of Abs against well-known HNA-1 to HNA-5, and also Abs against neutrophil antigens other than HNA-1 to HNA-5. Using these techniques, we found that most of the non-HLA WBC Abs detected in NHTR cases were against antigens other than HNA-1 to HNA-5. In addition, using our newly established neutrophil activation test, which assesses neutrophil activation elicited by immunologic stimuli such as WBC Abs and immune complex, we found that heparin-binding protein is a potential final effector molecule that induces NHTRs, including TRALI. More recently, we reported that the basophil activation test, which was originally developed to identify allergens in the field of allergic diseases, might be useful in transfusion medicine. In this review, we summarize these new techniques and other related tests.
