However, the functions of HLA-F and HLA-G in placental dysfunction remain unclear. The aim was to investigate differences in the prevalence of specific HLA-F and HLA-G gene allelic polymorphisms, genotypes, haplotypes, and diplotypes between controls and cases with preeclampsia or FGR. In total, blood samples from 365 pregnant females (controls, <i>n</i> = 192; preeclampsia, <i>n</i> = 164; FGR, <i>n</i> = 19) in their second and third trimester, and corresponding cordial blood samples (reflecting newborns, <i>n</i> = 160) were obtained after delivery. Genomic DNA was sequenced with a focus on the specific gene polymorphisms in the HLA-F gene locus, especially the single nucleotide polymorphisms (SNPs) rs1362126 (G/A), rs2523405 (T/G) and rs2523393 (A/G), as well as the rs371194629 (14-bp ins/del) in the 3′UTR of HLA-G. Haplotype and diplotype distributions were obtained using PHASE v2.1, and linkage disequilibrium analyses were performed. SNPs in the HLA-F gene locus and the 3′UTR of HLA-G were not associated with the risk of preeclampsia or FGR. The SNPs did not correlate with fetal-placental weight ratio, deviation of birth weight at gestational age, and placental weight. However, a trend towards an absence of certain HLA-F-HLA-G extended diplotypes in preeclampsia was observed. The current study does not support associations of the investigated HLA-F SNPs with preeclampsia or FGR. However, further studies are needed to evaluate the possible role of certain fetal HLA-F-HLA-G extended haplotypes and diplotypes in preeclampsia.</p>","PeriodicalId":13172,"journal":{"name":"HLA","volume":"106 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/tan.70293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observed two recipients awaiting kidney and liver transplantation with positive flow cytometry XM (FCXM) on T-cells in the absence of Donor Specific Antibodies (DSA). Both were treated with vedolizumab (VDZ) for an inflammatory bowel disease (IBD). VDZ is an IgG1 directed against integrin α4β7, expressed on T and B cell subsets, we therefore suspected that VDZ interfered with XM. We tested with Luminex screening and single antigen assays and with auto- and allo-FCXM on different HLA-typed cells several sera from the two recipients, collected before and during treatment with VDZ. To assess the intensity and the kinetics of the interference, the sera collected during VDZ treatment were from the induction and the maintenance phases at different times post-injection. All sera were DSA-negative with Luminex assays, indicating the absence of interference of VDZ with virtual XM. IgG allo-FCXM on T cells was positive during the maintenance phase while it was randomly positive on B cells. On T cells, the ratio was between 1.6 and 4.4 times the negative control (positivity threshold of 1.5) for the two recipients, and did not depend on the time between collection and injection. Unique T cell populations express Integrin α4β7, then we did not observe a global shift for T cells in the presence of VDZ but a shift for a small subset which was sufficient to induce a positive FCXM. VDZ treatment did not interfere with complement-dependent cytotoxicity XM or with IgM FCXM. Pronase treatment abrogated VDZ interference. In the event of unexpected positive FCXM on T cells in a recipient with IBD, the transplant team should seek VDZ treatment and interference.</p>\u0000 </div>","PeriodicalId":13172,"journal":{"name":"HLA","volume":"106 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
