Alloantibodies recognizing these blood group antigens determine blood compatibility, and the transfusion of incompatible blood can lead to life-threatening hemolytic transfusion reactions. Recently, the landscape of blood compatibility testing has been complicated due to the interference caused by therapeutic antibodies targeting CD38, a key target in cancer immunotherapy that is also expressed on red blood cells. The presence of anti-CD38 antibodies in blood samples has been found to bind to test or donor red blood cells, resulting in false positive tests. This interference poses a serious risk as it can potentially mask immunogenic alloantibodies and cause delays in supplying safe blood products. We present the development and application of fragment crystallizable (Fc)-fusion constructs, referred to as \"baitbodies\", designed to neutralize anti-CD38 antibodies and mitigate false positive test outcomes. The extracellular domain of CD38 was fused to the Fc domain of a murine immunoglobulin G. These baitbody constructs were thoroughly characterized and applied in both serological microcolumn agglutination and automated solid-phase red cell adherence assays. The CD38-mFc baitbody successfully prevented agglutination reactions induced by three clinically relevant anti-CD38 monoclonal antibodies-daratumumab, felzartamab and isatuximab-in spiked samples. This allowed the detection of alloantibodies of the Rhesus, Kell and Duffy blood groups without interference. The CD38-mFc construct also demonstrated potential in a head-to-head comparison with commercial mitigation reagents, DaraEx and Grifols sCD38.

Tumor tissues of CHL from Cancer Hospital, Chinese Academy of Medical Sciences and the public dataset from GSE17920 were analyzed. Immunohistochemistry was performed to detect the expression of CD47, programmed cell death protein 1 (PD-1), and PD ligand 1 (PD-L1) in CHL.

Bioinformatic analyses included differentially expressed genes (DEGs) screening, functional enrichment, and immune infiltration (CIBERSORT) were performed using GSE17920. In the study, CD47 expression was analyzed in both tumor cells (CD47tumor_score) and the TME (CD47micro_score) of CHL patients.

Univariate Cox regression identified high CD47micro_score as a significant predictor of inferior overall survival (OS; hazard ratio [HR] = 4.91, p = 0.03). Additionally, high CD47 expression correlated with increased PD-L1, and patients with concurrent high CD47 and positive PD-L1 of tumor cells had the shortest PFS, although this trend was not statistically significant.

Although there are many therapeutic medicines targeting the pathogenic mechanisms, there is currently a lack of curative or long-term symptom control options. Chimeric antigen receptor (CAR) cells are engineered cells that express multifunctional synthetic receptors. These CAR cells specifically target killer pathogenic immune cells and offer a novel approach to treating AIDs by modulating the immune microenvironment. Recent studies have demonstrated satisfactory outcomes with this method in managing autoimmune conditions. In our review paper, we provide a comprehensive summary of previous cases utilizing CAR cell therapy for AIDs. We hope that our review will provide clinicians with more options for the treatment of AIDs.</p>","PeriodicalId":15952,"journal":{"name":"Journal of Immunology Research","volume":"2026 1","pages":"e6629562"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13140878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147433338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
