Abstract
INTRODUCTION Vitamin D receptor (VDR) gene and its polymorphisms are highlighted as candidate components for susceptibility to various autoimmune diseases. The aim of this study was to investigate the role of VDR polymorphisms (rs2228570, rs1544410, rs7975232, and rs731236) in aplastic anemia (AA). METHODS In this case-control study, the genotyping of VDR rs1544410 (c.1024 + 283G>A), rs7975232 (c.1025-49G>T), and rs731236 (c.1056T>C) polymorphisms was conducted using polymerase chain reaction (PCR)-ligase detection reaction, while the genotyping of rs2228570 (c.2T>C) was detected by PCR-restriction fragment length polymorphism. RESULTS The frequencies of GG genotype and G allele of rs1544410 were significantly higher in patients with AA than in controls. Further analysis indicated that rs1544410 and rs7975232 polymorphisms were correlated with the risk to nonsevere AA, while rs2228570 was relevant to severe AA. Moreover, TT carriers of rs2228570 were closely associated with a poor response to treatment and a higher risk of myelodysplastic syndrome/acute leukemia transformation, while CT carriers more easily evolved to overt paroxysmal nocturnal hemoglobinuria. CONCLUSIONS VDR polymorphisms may contribute to susceptibility to AA and influence the severity and prognosis of AA in a Chinese population.

Abstract
T-box transcription factor protein (TBX21) is encoded by the TBX21 gene in human. It is crucial for naive T lymphocyte development, interferon-γ production, airway hyperresponsiveness and regulation of corticosteroid response in asthmatics. Polymorphisms rs4794067 and rs16947078 of TBX21 were found to be associated with acetylsalicylic acid-induced and allergic asthma, respectively. We examined whether sequence variants of TBX21 gene are associated with asthma and its severity in Indian population. In a hospital-based case-control study, 240 asthmatic children and 240 healthy controls were investigated for the association of TBX21 rs4794067 (C>T) and rs16947078 (G>A) polymorphisms with asthma and its severity using PCR-restriction fragment length polymorphism method. Heterozygous (CT) (odds ratio (OR)=2.33; P=0.001) and variant (TT) (OR=6.25; P=0.001) genotypes of rs4794067 were demonstrated significant risk of asthma. However, in asthma severity variant (TT) genotype revealed significant increase risk (intermittent: OR=5.9, P=0.001; mild: OR=8.0, P=0.001; moderate: OR=3.2, P=0.041; and severe: OR=43.6, P=0.001) in all subgroups. Furthermore, haplotypes TG (OR=2.83; P=0.001) and TA (OR=2.54; P=0.001) of TBX21 were associated with an increased risk of asthma. Conversely, rs16947078 G>A polymorphism was not associated with any asthma/asthma severity risk. These data suggest that TBX21 gene variation may modify individual's susceptibility to asthma and its severity in Indian population. However, further validation in large population-based studies is needed to confirm the finding.

The polymorphisms of T cell-specific TBX21 gene may contribute to the susceptibility of chronic immune thrombocytopenia in Chinese population. Hum Immunol 2013; 75:129-33. [PMID: 24262372 DOI: 10.1016/j.humimm.2013.11.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2013] [Revised: 11/05/2013] [Accepted: 11/11/2013] [Indexed: 02/07/2023]
Abstract
Chronic primary immune thrombocytopenia (ITP) is an acquired autoimmune hemorrhagic disease characterized by both reduced platelet counts and suppression of megakaryocyte and platelet development. T cell-specific T-box transcription factor gene (TBX21) plays a critical role in the development and maintenance of T helper 1 (Th1) cells. Recently, several studies have confirmed that the T-1554C and T-1993C polymorphisms of this gene can influence its expression level and are associated with autoimmune diseases. Therefore, we speculated that TBX21 polymorphisms might be associated with the susceptibility of chronic ITP in Chinese population. We investigated the distributions of TBX21 (T-1514C and T-1993C) polymorphisms in 275 patients with chronic ITP and 261 healthy controls by polymerase chain reaction-restriction fragment length polymorphism. We observed significant overrepresentation of T allele and T/T genotype at T-1993C (but not T-1514C) in patients compared with controls. Stratified analysis by gender and age of disease onset revealed comparable observations in both female and childhood ITP cohorts. In conclusion, the T-1993C polymorphisms of TBX21 gene may be associated with the susceptibility of chronic primary ITP in Chinese population.

Abstract
Notch1 signaling sustains the proinflammatory behavior of Th1 cells, implicated in the development of aplastic anemia in humans and mice. Severe aplastic anemia (AA) is a bone marrow (BM) failure (BMF) disease frequently caused by aberrant immune destruction of blood progenitors. Although a Th1-mediated pathology is well described for AA, molecular mechanisms driving disease progression remain ill defined. The NOTCH signaling pathway mediates Th1 cell differentiation in the presence of polarizing cytokines, an action requiring enzymatic processing of NOTCH receptors by γ-secretase. Using a mouse model of AA, we demonstrate that expression of both intracellular NOTCH1IC and T-BET, a key transcription factor regulating Th1 cell differentiation, was increased in spleen and BM-infiltrating T cells during active disease. Conditionally deleting Notch1 or administering γ-secretase inhibitors (GSIs) in vivo attenuated disease and rescued mice from lethal BMF. In peripheral T cells from patients with untreated AA, NOTCH1IC was significantly elevated and bound to the TBX21 promoter, showing NOTCH1 directly regulates the gene encoding T-BET. Treating patient cells with GSIs in vitro lowered NOTCH1IC levels, decreased NOTCH1 detectable at the TBX21 promoter, and decreased T-BET expression, indicating that NOTCH1 signaling is responsive to GSIs during active disease. Collectively, these results identify NOTCH signaling as a primary driver of Th1-mediated pathogenesis in AA and may represent a novel target for therapeutic intervention.

Genetic associations in acquired immune-mediated bone marrow failure syndromes: insights in aplastic anemia and chronic idiopathic neutropenia. Clin Dev Immunol 2012; 2012:123789.

Abstract
Increasing interest on the field of autoimmune diseases has unveiled a plethora of genetic factors that predispose to these diseases. However, in immune-mediated bone marrow failure syndromes, such as acquired aplastic anemia and chronic idiopathic neutropenia, in which the pathophysiology results from a myelosuppressive bone marrow microenvironment mainly due to the presence of activated T lymphocytes, leading to the accelerated apoptotic death of the hematopoietic stem and progenitor cells, such genetic associations have been very limited. Various alleles and haplotypes of human leucocyte antigen (HLA) molecules have been implicated in the predisposition of developing the above diseases, as well as polymorphisms of inhibitory cytokines such as interferon-γ, tumor necrosis factor-α, and transforming growth factor-β1 along with polymorphisms on molecules of the immune system including the T-bet transcription factor and signal transducers and activators of transcription. In some cases, specific polymorphisms have been implicated in the outcome of treatment on those patients.
