Repeated implantation failure (RIF) is one of the most prominent problems in the field of assisted reproduction. Neu5Gc on the surface of decidual macrophages (dMΦ) leads to different activation patterns of dMΦ, which affects embryo implantation and development. Cmah−/− (Neu5Gc-deficient) mice induced to produce anti-Neu5Gc antibodies in vivo were given a special diet rich in Neu5Gc and their fertility was monitored. The long-term diet rich in Neu5Gc induced the decrease of endometrial receptivity of female mice. The pregnancy rate of female mice fed the normal diet was 63.6% (n = 11) and the average number of embryos was 9.571 ± 1.272, while the pregnancy rate of female mice fed the diet rich in Neu5Gc was 36.4% (n = 11) and the average number of embryos in pregnant mice was 5.750 ± 3.304. The intake of Neu5Gc and the production of anti-Neu5Gc antibody led to M1 polarization of endometrial dMΦ and abnormal embryo implantation.

While chemotherapeutic agents were long solely associated with immunosuppression, clinical data demonstrate that the combination of some chemotherapies with immunomodulators can be beneficial against cancer. Defining combinations featuring optimal anticancer activity along with minimal toxicity remains however a major challenge. Clinical evidence suggests that immune responses in patients treated with combination therapies are associated with progression-free survival. Progress in understanding the mechanisms responsible for anticancer immune responses following chemotherapy administration facilitated the translation of relevant chemoimmunotherapy combinations in the clinic.

Multiple transcript isoforms of genes can be formed by processing and modifying the 5′ and 3′ ends of RNA. Herein, the aim of this study is to uncover the characteristics of RNA processing modification (RPM) in hepatocellular carcinoma (HCC), and to identify novel biomarkers and potential targets for treatment. Firstly, integrated bioinformatics analysis was carried out to identify risk prognostic RPM regulators (RPMRs). Then, we used these RPMRs to identify subtypes of HCC and explore differences in immune microenvironment and cellular function improvement pathways between the sub-types. Finally, we used the principal component analysis algorithms to estimate RPMscore, which were applied to 5 cohorts. Lower RPMscore among patients correlated with a declined survival rate, increased immune infiltration, and raised expression of immune checkpoints, aligning with the “immunity tidal model theory”. The RPMscore exhibited robust, which was validated in multiple datasets. Mechanistically, low RPMscore can create an immunosuppressive microenvironment in HCC by manipulating tumor-associated macrophages. Preclinically, patients with high RPMscore might benefit from immunotherapy. The RPMscore is helpful in clustering HCC patients with distinct prognosis and immunotherapy. Our RPMscore model can help clinicians to select personalized therapy for HCC patients, and RPMscore may act a part in the development of HCC.

The transcription factor BCL11B plays an essential role in the development of central nervous system and T cell differentiation by regulating the expression of numerous genes involved in several pathways. Monoallelic defects in the BCL11B gene leading to loss-of-function are associated with a wide spectrum of phenotypes, including neurological disorders with or without immunological features and susceptibility to hematological malignancies. From the genetic point of view, the landscape of BCL11B mutations reported so far does not fully explain the genotype-phenotype correlation. In this review, we sought to compile the phenotypic and genotypic variables associated with previously reported mutations in this gene in order to provide a better understanding of the consequences of deleterious variants. We also highlight the importance of a careful evaluation of the mutation type, its location and the pattern of inheritance of the variants in order to assign the most accurate pathogenicity and actionability of the genetic findings.
转录因子 BCL11B 在中枢神经系统发育和 T 细胞分化过程中起着至关重要的作用，它调控着参与多种途径的众多基因的表达。BCL11B 基因的单倍性缺陷导致的功能缺失与多种表型有关，包括伴有或不伴有免疫学特征的神经系统疾病以及对血液恶性肿瘤的易感性。从遗传学的角度来看，迄今所报道的 BCL11B 基因突变情况并不能完全解释基因型与表型之间的相关性。在这篇综述中，我们试图梳理与之前报道的该基因突变相关的表型和基因型变量，以便更好地了解有害变异的后果。我们还强调了仔细评估变异类型、变异位置和变异遗传模式的重要性，以便最准确地确定遗传结果的致病性和可操作性。

Meniere Disease (MD) is a chronic inner ear disorder characterized by vertigo attacks, sensorineural hearing loss, tinnitus, and aural fullness. Extensive evidence supporting the inflammatory etiology of MD has been found, therefore, by using transcriptome analysis, we aim to describe the inflammatory variants of MD. We performed Bulk RNAseq on 45 patients with definite MD and 15 healthy controls. MD patients were classified according to their basal levels of IL-1β into 2 groups: high and low. Differentially expression analysis was performed using the ExpHunter Suite, and cell type proportion was evaluated using the estimation algorithms xCell, ABIS, and CIBERSORTx. MD patients showed 15 differentially expressed genes (DEG) compared to controls. The top DEGs include IGHG1 (p = 1.64 $$times$$ 10−6) and IGLV3-21 (p = 6.28 $$times$$ 10−3), supporting a role in the adaptative immune response. Cytokine profiling defines a subgroup of patients with high levels of IL-1β with up-regulation of IL6 (p = 7.65 $$times$$ 10−8) and INHBA (p = 3.39 $$times$$ 10−7) genes. Transcriptomic data from peripheral blood mononuclear cells support a proinflammatory subgroup of MD patients with high levels of IL6 and an increase in naïve B-cells, and memory CD8+ T cells.

Limited CAR T-cell expansion and persistence hinder therapeutic responses in solid cancer patients. To enhance the functional persistence of engineered T-cell therapies, we performed genetic disruption in human CAR T cells of SUV39H1, a histone 3 lysine 9 methyltransferase that promotes heterochromatin formation. This resulted in phenotypic CAR-T reprogramming that elicited optimal and sustained antitumor functionality. Single-cell transcriptomic (scRNA-seq) and chromatin accessibility (scATAC-seq) analyses of tumor-infiltrating CAR T cells showed early reprogramming into self-renewing, stem-like populations with decreased expression of dysfunction genes in all subpopulations. Moreover, we provided evidence that SUV39H1 inactivation elicits potent and durable functional persistence upon multiple tumor rechallenges. This opens a safe path to enhancing adoptive cell therapies for solid tumors.
有限的 CAR T 细胞扩增和持久性阻碍了实体瘤患者的治疗反应。为了提高工程 T 细胞疗法的功能持久性，我们在人类 CAR T 细胞中对 SUV39H1 进行了基因干扰，SUV39H1 是组蛋白 3 赖氨酸 9 甲基转移酶，能促进异染色质的形成。这导致了表型 CAR-T 重编程，从而激发了最佳和持续的抗肿瘤功能。对肿瘤浸润CAR-T细胞进行的单细胞转录组（scRNA-seq）和染色质可及性（scATAC-seq）分析表明，CAR-T细胞早期重编程为自我更新的干样细胞群，所有亚群中功能障碍基因的表达均有所下降。此外，我们还提供了证据表明，SUV39H1 失活可在多次肿瘤再挑战后产生强大而持久的功能持续性。这为加强实体瘤的采纳细胞疗法开辟了一条安全之路。

Controversial data have been reported on the prognostic value of C-X-C motif chemokine receptor 4 (CXCR4) in chronic lymphocytic leukemia (CLL). This prospective, single-center, observational study aimed to evaluate the role of CXCR4 in the pathophysiology of CLL and its prognostic role. A total of 158 patients of CLL were enrolled, and CXCR4 expression on CLL cells was detected by flow cytometry (FCM) at initial diagnosis. The patients were divided into 2 groups according to the CXCR4 mean fluorescence intensity (MFI) median. Also, four patient specimens from the CXCR4low and CXCR4high groups were selected for RNASeq analysis. The progression-free survival (PFS) of CLL patients in the CXCR4high group was significantly shorter than the CXCR4low group, with a median follow-up time of 27 months (log-rank P < 0.001). Moreover, CXCR4 overexpression (MFI > 3376) was an independent marker of poor PFS in CLL patients (P < 0.001). Analysis of RNASeq results revealed that CXCR4 plays an important role in the migration of CLL. Collectively, CXCR4 expression levels on leukemia cells can be detected rapidly by FCM. CXCR4 overexpression was significantly associated with poorer prognosis in CLL patients within a shorter follow-up time.
