简介：AbstractAdult T-cell leukemia/lymphoma (ATLL) is an aggressive peripheral T-cell lymphoma caused by the human T lymphotropic virus type-1. The skin is affected in approximately half of ATLL patients, and skin lesions may be the first manifestation of the disease. The skin lesions of ATLL are polymorphous, and depend on the type of skin eruption, which makes it possible for doctors to predict the prognosis of the disease based on the characteristics of skin lesions. In this review article, we describe the clinical manifestations and histopathological patterns of skin lesions in ATLL, focus on its diagnostic and prognostic significance, and also summarize the advances in the treatment of ATLL.

简介：AbstractObjective:To analyze the proportion of peripheral regulatory T cells (Tregs) and the expression of the immune checkpoint molecules T-cell immunoglobulin and ITIM domain (TIGIT) and CD226 on Tregs in patients with recurrent spontaneous abortion (RSA).Methods:The proportion of CD3+CD4+CD25+Foxp3+ Tregs and the expression levels of CD226 and TIGIT on Tregs in 30 normal pregnant women and 28 patients with RSA were determined via flow cytometry.Results:The proportion of Tregs in the RSA group (4.41 % ± 1.54%) was significantly lower than that in the control group (5.27% ± 1.52%, P = 0.0374). Compared with the normal pregnant women, patients with RSA showed decreased TIGIT expression (54.75 ± 9.70% vs. 63.07 ± 12.48%, P = 0.0066) and increased CD226 expression on Tregs (25.59% ± 8.22% vs. 20.46% ± 6.97%, P = 0.0168). The ratio of CD226 to TIGIT in the RSA group (0.48 ± 0.19) was higher than that in the control group (0.34 ± 0.15, P = 0.0027). The proportion of TIGIT+CD226+ Tregs was significantly lower in patients with RSA (9.30% ± 4.95% vs. 13.43% ± 4.72%, P = 0.0020) than in the controls.Conclusions:Patients with RSA show a reduced proportion of Tregs and an imbalance in the expression of TIGIT and CD226 on Tregs.

简介：AbstractLike antibody evaluation, using an effective antigen-specific T-cell immunity assessment method in coronavirus disease 2019 (COVID-19) patients, survivors and vaccinees is crucial for understanding the immune persistence, prognosis assessment, and vaccine development for COVID-19. This study evaluated an empirically adjusted enzyme-linked immunospot assay for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific T-cell immunity in 175 peripheral blood samples from COVID-19 convalescents and healthy individuals. Results of viral nucleic acid were used as the gold standard of infection confirmation. The SARS-CoV-2M peptide pool had higher sensitivity of 85% and specificity of 71% for the single peptide pool. For combined peptide pools, the parallel evaluation (at least one of the peptide pools is positive) of total peptide pools (S1&S2&M&N) had higher sensitivity (up to 93%), and the serial evaluation (all peptide pools are positive) of total peptide pools had higher specificity (up to 100%). The result of the serial evaluation was better than that of the parallel evaluation as a whole. The detection efficiency of M and N peptide pool serial evaluation appeared the highest, with a sensitivity of 80% and specificity of 93%. This T-cell immunity detection assay introduced in this report can achieve high operability and applicability. Therefore, it can be an effective SARS-CoV-2-specific cellular immune function evaluation method.

简介：AbstractBackground:There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China.Methods:From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n = 72) or allo-HSCT (n = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups.Results:Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P= 0.001), chemotherapy-resistant disease (41% vs. 8%, P= 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300).Conclusions:Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

简介：与一级的CD8约会主要组织亲和性抗原极大地提高T房间激活，但是这怎么被完成，不是清楚的。我们探讨CD8的调停抗体的结扎是否独自导致在T房间克隆改变的transcriptional的问题，用基因表示的连续分析。尽管它没能导致公开phenotypic变化，我们发现CD8结扎深刻地在T房间克隆改变抄写，在比得上由CD3的调停抗体的结扎导致了那的规模。然而，产生变化的特性与是实质地禁止的CD8结扎的网效果是不同的。我们推测那绑扎的CD8导致弱，T房间受体(TCR)调停了TCR对手的效果暗示的禁止的信号。我们的结果暗示CD8结扎独自不能因为它没能充分导致NFAT依赖的抄写，激活T房间克隆。

简介：Granulocyte巨噬细胞刺激殖民地的因素(GM-CSF)是一个重要造血的生长因素和有免疫力的调节的人。GM-CSF也在各种各样的传播白血球的功能的活动有深刻效果。它被许多房间类型在收到有免疫力的刺激之上包括T房间，巨噬细胞，endothelial房间和成纤维细胞生产。尽管GM-CSF局部地被生产，它能以一种paracrine方式行动到在主人防卫提高他们的功能的成员传播neutrophils，单核白血球和淋巴细胞。最近的集中的调查为它增加树枝状的房间(DC)成熟和功能以及巨噬细胞活动的能力作为一个有免疫力的助手在GM-CSF的应用程序上被集中。在经历化疗的癌症病人对待嗜中性白血球减少症临床上被使用，在在治疗期间的爱滋病病人，并且在在骨髓移植以后的病人。有趣地，GM-CSF-deficient老鼠的造血的系统看起来正常；最重要的变化在一些特定的T房间回答。尽管GM-CSF的分子的克隆用T房间的cDNA图书馆被执行，T房间在激活以后生产GM-CSF，是众所周知的，在T房间功能上有在由T房间和它的效果的生产的这cytokine的系统的调查的缺乏。在这篇文章，我们将在T房间主要集中于GM-CSF的免疫生物学。

简介：免疫疗法和化疗的联合为癌症的某些类型的治疗被认为是一条有希望的途径。然而，内在的机制需要充分被调查为癌症chemoimmunotherapy指导更有效的协议的设计。联系危险的分子的模式(阻尼)能激活有免疫力的房间，是众所周知的，包括树枝状的房间(DC)，经由像使用费的受体(TLR)；然而，在有免疫力的反应的激活免除化学对待药的肿瘤房间的阻尼的角色需要进一步被阐明。这里，我们发现那colorectal与oxaliplatin(OXA)对待的癌症(CRC)房间或5氟尿嘧啶(5-Fu)释放了高活动性的组盒子1的高水平(HMGB1)和热吃惊蛋白质70(HSP70)。在OXA/5-Fu治疗以后，也展出的CRC病人的sera增加了HMGB1和HSP70的层次，哪个是著名阻尼。与OXA/5-Fu对待的垂死的CRC房间的上层清液支持了老鼠和人的DC成熟，与HLA医生，CD80和CD86表示和IL-1β的改进的upregulation；，TNF-α；，MIP-1α；，MIP-1β；，RANTES和IP-10生产。由DC组成的疫苗与导致的化学上强调的CRC房间的上层清液搏动了更重要的IFN-γ；在vitro并且在vivo生产Th1反应。然而，化学上强调的CRC房间的上层清液没能在TLR4缺乏的DC导致phenotypic成熟和cytokine生产，显示在导致阻尼的DC成熟和激活的TLR4的一个必要角色。而且，有化学上强调的CRC房间的上层清液的pulsing高效地没导致IFN-γ；在TLR4缺乏的DC生产Th1反应。一起，这些结果证明免除化学上强调的癌症房间的阻尼能经由TLR4激活DC并且提高反肿瘤T房间有免疫力的回答的正式就职，描出一条临床上相关的免疫助手小径由阻尼被触发。

简介：AbstractBackground:The role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with high-risk (HR) T-cell acute lymphoblastic leukemia (T-ALL) in first complete remission (CR1) is still under evaluation. Moreover, relapse is the main factor affecting survival. This study aimed to explore the effect of allo-HSCT (especially haploidentical HSCT [haplo-HSCT]) on improving survival and reducing relapse for HR childhood T-ALL in CR1 and the prognostic factors of childhood T-ALL in order to identify who could benefit from HSCT.Methods:A total of 74 newly diagnosed pediatric T-ALL patients between January 1, 2012 and June 30, 2018 were enrolled in this retrospective study. Patients were stratified into the low-risk chemotherapy cohort (n = 16), HR chemotherapy cohort (n = 31), and HR transplant cohort (n = 27). Characteristics, survival outcomes, and prognostic factors of all patients were then analyzed.Results:Patient prognosis in the HR chemotherapy cohort was significantly worse than that in the low-risk chemotherapy cohort (5-year overall survival [OS]: 58.5% vs. 100%, P = 0.003; 5-year event-free survival [EFS]: 54.1% vs. 83.4%, P = 0.010; 5-year cumulative incidence of relapse [CIR]: 45.2% vs. 6.3%, P = 0.011). In HR patients, allo-HSCT improved the 5-year EFS and CIR compared to that of chemotherapy (5-year EFS: 80.1% vs. 54.1%, P = 0.041; 5-year CIR: 11.6% vs. 45.2%, P = 0.006). The 5-year OS was higher in the HR transplant cohort than that in the HR chemotherapy cohort (81.0% vs. 58.5%, P = 0.084). Minimal residual disease re-emergence was an independent risk factor for 5-year OS, EFS, and CIR; age ≥10 years was an independent risk factor for OS and EFS; and high white blood cell count was an independent risk factor for EFS and CIR.Conclusion:Allo-HSCT, especially haplo-HSCT, could effectively reduce relapse of children with HR T-ALL in CR1.
