[PMID: 37211482 DOI: 10.1016/j.medcli.2023.03.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 03/10/2023] [Accepted: 03/15/2023] [Indexed: 05/23/2023]
Abstract
OBJECTIVE The study aims to evaluate the role of anti-high mobility group box 1 (HMGB1) antibody and anti-moesin antibody in the diagnosis of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and its possible relationship with the different clinical manifestations. METHODS The study involved 60 AAV patients, 58 patients with autoimmune disease other than AAV and 50 healthy subjects. The serum levels of anti-HMGB1 and anti-moesin antibodies were determined by enzyme-linked immunosorbent assay (ELISA), and the second determination was made 3 months after treatment of AAV patients. RESULTS Serum levels of anti-HMGB1 and anti-moesin antibodies in AAV group were significantly higher than those in non-AAV group and HC group. The area under the curve (AUC) of anti-HMGB1 and anti-moesin in diagnosing AAV were 0.977 and 0.670, respectively. Anti-HMGB1 levels were significantly elevated in AAV patients with pulmonary involvement, while the concentrations of anti-moesin were significantly increased in patients with renal damage. Anti-moesin were positively correlated with BVAS (r=0.261, P=0.044), creatinine (r=0.296, P=0.024) and negatively correlated with complement C3 (r=-0.363, P=0.013). Besides, anti-moesin levels of active AAV patients were significantly higher than those in inactive patients. The concentrations of serum anti-HMGB1 could be significantly decreased after induction remission treatment (P<0.05). CONCLUSION Anti-HMGB1 and anti-moesin antibodies play important roles in the diagnosis and prognosis of AAV, which may act as potential disease markers for AAV.

Abstract
Acquired bone marrow failure syndromes encompass a unique set of disorders characterized by a reduction in the effective production of mature cells by the bone marrow (BM). In the majority of cases, these syndromes are the result of the immune-mediated destruction of hematopoietic stem cells or their progenitors at various stages of differentiation. Microbial infection has also been associated with hematopoietic stem cell injury and may lead to associated transient or persistent BM failure, and recent evidence has highlighted the potential impact of commensal microbes and their metabolites on hematopoiesis. We summarize the interactions between microorganisms and the host immune system and emphasize how they may impact the development of acquired BM failure.

Abstract
Human parvovirus B19 is a single-stranded DNA virus which preferentially targets the erythroblasts in the bone marrow. B19 infection commonly causes erythema infectiosum, arthralgia, fetal death, transient aplastic crisis in patients with shortened red cell survival, and persistent infection in people who are immunocompromised. Less common clinical manifestations include atypical skin rashes, neurological syndromes, cardiac syndromes, and various cytopenias. B19 infection has also been associated with development of a variety of different autoimmune diseases, including rheumatological, neurological, neuromuscular, cardiovascular, haematological, nephrological and metabolic. Production of a variety of autoantibodies has been demonstrated to occur during B19 infection and these have been shown to be key to the pathogenesis of the particular disease process in a significant number of cases, for example, production of rheumatoid factor in cases of B19-associated rheumatoid arthritis and production of anti-glutamic acid decarboxylase (GAD) in patients with B19-associated type 1 diabetes mellitus. B19 infection has also been associated with the development of multiple autoimmune diseases in 12 individuals. Documented mechanisms in B19-associated autoimmunity include molecular mimicry (IgG antibody to B19 proteins has been shown to cross react with a variety of recognised human autoantigens, including collagen II, keratin, angiotensin II type 1 receptor, myelin basic protein, cardiolipin, and platelet membrane glycoprotein IIb/IIIa), B19-induced apoptosis with presentation of self-antigens to T lymphocytes, and the phospholipase activity of the B19 unique VP1 protein.

Abstract
The mechanism of acquired aplastic anemia (AA), a bone marrow hematopoiesis failure disease, has not been fully understood. TNF-α is a pleiotropic cytokine involved in cell proliferation, differentiation and death, and inflammation through binding to specific receptors on cell membranes. Aberrant secretion of TNF-α contributes to a number of human diseases, including tumor development and inflammation. TNF-α is also an important negative regulator of hematopoiesis. Over-expression of TNF-α not only directly inhibits the proliferation and differentiation of hematopoietic cells, but also initiates the intracellular death pathway to induce hematopoietic cell death, leading to bone marrow hematopoiesis failure. In this review, we summarize the mechanisms underlying extrinsic apoptosis and necroptosis of hematopoietic cells induced by TNF-α, and discuss the role of TNF-α-induced programmed cell death in the pathogenesis of acquired AA.

Abstract
BACKGROUND Antineutrophil cytoplasmic autoantibody (ANCA) directed against myeloperoxidase (MPO), a diagnostic criterion in MPO-ANCA-associated vasculitis (MPO-AAV), does not always correlate with disease activity. Here, we detected autoantibodies against moesin, which was located on the surface of stimulated endothelial cells, in the serum of patients. METHODS The anti-moesin autoantibody titer was evaluated by ELISA. Seventeen kinds of cytokines/chemokines were measured by a Bio-Plex system. RESULTS Serum creatinine in the anti-moesin autoantibody-positive group was higher than that in the negative group. Additionally, interferon (IFN)-γ, macrophage chemotactic peptide-1 (MCP-1), interleukin (IL)-2, IL-7, IL-12p70, IL-13, granulocyte/macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor were significantly higher in the positive group. Furthermore, IL-7 and IL-12p70 levels correlated with the anti-moesin autoantibody titer. Based on these findings and the binding of anti-moesin IgG to neutrophils and monocytes, we detected the secretion of cytokines/chemokines such as IFN-γ, MCP-1 and GM-CSF from these cells. CONCLUSIONS The anti-moesin autoantibody existed in the serum of patients with MPO-AAV and was associated with the production of inflammatory cytokines/chemokines targeting neutrophils with a cytoplasmic profile, which suggests that the anti-moesin autoantibody has the possibility to be a novel autoantibody developing vasculitis via neutrophil and endothelial cell activation.

Abstract
The powerful activating receptor NKG2D is expressed by natural killer (NK) cells and promotes cytotoxic lysis of cancer cells expressing NKG2D ligands (NKG2D-Ls). We report the effective induction of NKG2D-Ls, achieved with the naturally occurring polyphenol resveratrol, in a broad range of leukemia cells. In this study, resveratrol upregulated the NKG2D-Ls MHC class I chain-related proteins MICA and MICB, and UL16-binding proteins ULBP1, ULBP2, and ULBP3 in most of the leukemia cells analyzed. Ligand upregulation induced by resveratrol was impaired by pharmacological and genetic disruption of ataxia-telangiectasia mutated kinase, the main regulator of NKG2D-L expression. Leukemia cells treated with resveratrol were more susceptible to killing by NK cells than untreated cells, and the enhanced cytotoxicity of NK cells was blocked by treatment of NK cells with anti-NKG2D mAbs. Interestingly, resveratrol consistently upregulated the NKG2D receptor expression and enhanced NKG2D-mediated functions in resting NK cells obtained from healthy individuals. Therefore, resveratrol has attractive immunotherapeutic potential.

Abstract
Viscum album agglutinin-I (VAA-I) is a plant lectin, which possesses anti-inflammatory properties, including the ability to induce neutrophil apoptosis by a mechanism that is not completely understood. Among the three actin-binding membrane-anchoring proteins ezrin/radixin/moesin (ERM), neutrophils are known to express ezrin and moesin. The behavior of these proteins in apoptotic neutrophils is not well established. In the present study, the expression and localization of ezrin and moesin by Western blot and immunofluorescence revealed a clear degradation and relocalization of both the proteins during VAA-I-induced apoptosis. Also, flow cytometry analysis revealed that VAA-I markedly and significantly induced the cell surface expression of ezrin and moesin and this was reversed when cells were pretreated with the Syk inhibitor piceatannol. The expression of ezrin and moesin on the cell surface of apoptotic neutrophils may represent a mechanism responsible for the appearance of autoantibodies directed against ERM proteins, which have been found in the serum of patients suffering from autoimmune diseases. Therefore, the ability of VAA-I to increase cell surface expression of cytoskeletal proteins in apoptotic neutrophils provides important insight into a possible toxic mechanism of this plant lectin and this has to be considered for its potential utilization for in vivo treatment.

Abstract
Aplastic crisis is an unusual feature of systemic lupus erythematosus (SLE). We report the case of a 54-year-old woman presenting with both (extravascular) Coombs-positive hemolytic anemia and laboratory findings of bone marrow hyporegeneration with concomitant severe neutropenia. A bone marrow biopsy confirmed aplastic crisis. Diagnostic work-up revealed soaring titers of autoantibodies (anti-nuclear, anti-double-stranded DNA, anti-cardiolipin-IgM, and anti-β2-glykoprotein-IgM antibodies), indicating a connective tissue disease as the most plausible reason for bone marrow insufficiency. As the criteria for SLE were fulfilled, we initiated an immunosuppressive therapy by steroids, which led to a rapid complete hematologic and clinical remission in our patient. In this case, we could report on one of the rare cases of SLE-induced aplastic crisis showing that this condition can be entirely reversed by immunosuppressive treatment and that SLE-induced aplastic crisis yields a good prognosis. In conclusion, in a case of aplastic crisis, physicians should be aware that SLE can be a rare cause that is accessible to specific treatment.
