    Systemic sclerosis (SSc) is a complex disease, in which an interaction of genetic and environmental factors plays an important role in its development and pathogenesis. A number of genetic studies, including candidate gene analysis and genome-wide association study, have found that the associated genetic variants are mainly localized in noncoding regions in the expression quantitative trait locus and influence corresponding gene expression. The gene variants identified as a risk for SSc susceptibility include those associated with innate immunity, adaptive immune response, and cell death, while there are only few SSc-associated genes involved in the fibrotic process or vascular homeostasis. Human leukocyte antigen class II genes are associated with SSc-related autoantibodies rather than SSc itself. Since the pathways between the associated genotype and phenotype are still poorly understood, further investigations using multi-omics technologies are necessary to characterize the complex molecular architecture of SSc, identify biomarkers useful to predict future outcomes and treatment responses, and discover effective drug targets.

    Systemic sclerosis (SSc) is a connective tissue disease characterized by excessive fibrosis, microvasculopathy, and autoimmunity. Endothelial cell (EC) injury and subsequent endothelial cell dysfunction is believed to be an initial event that eventually leads to a vicious pathogenic cycle. This process is further enhanced by defective angiogenesis and vasculogenesis, as the vascular repair machinery does not work properly. Endothelial progenitor cells (EPCs) are functionally and quantitatively insufficient to recover the endothelium in SSc patients. The dysfunctional ECs and EPCs not only trigger the formation of typical vascular lesions, such as progressive intimal fibrosis in small arteries and the loss of capillaries, but also promote a series of inflammatory and profibrotic processes, such as endothelial-mesenchymal transition and recruitment and accumulation of monocytic EPCs with profibrotic properties. These processes together contribute to the accumulation of extracellular matrix in the affected tissue. This review features current insights into the roles of ECs and EPCs in the pathogenesis of SSc.

    Systemic sclerosis (SSc) is a multi-organ fibrotic disease that affects the skin and various internal organs. Therapeutic strategies for tissue fibrosis have not been established; however, aberrantly activated fibroblasts in affected lesions are key targets for modulating fibrosis. Recently, increased intracellular cyclic GMP (cGMP) levels were demonstrated to improve fibrosis levels in various diseases. The purpose of this study was to assess the antifibrotic properties of cGMP in cultured fibroblasts from patients with SSc. The phosphodiesterase (PDE) 5 inhibitor sildenafil increased the intracellular cGMP levels in skin fibroblasts in a dose-dependent manner. Sildenafil treatment also significantly decreased the expression of several pro-fibrotic factors that were upregulated by TGF-beta 1 treatment in SSc skin fibroblasts. These inhibitory effects occurred via non-canonical TGF-beta signaling. Our findings revealed that sildenafil might be a novel strategy to treat tissue fibrosis and vasculopathy in SSc.

    Objective. PM and DM are often complicated by interstitial lung disease (ILD). In this study we aimed to evaluate various serum cytokines in patients with PM/DM with ILD so as to clarify the differences in pathophysiology between anti-melanoma differentiation-associated gene 5 antibody-associated ILD (anti-MDA5-ILD) and anti-aminoacyl tRNA synthetase antibody-associated ILD (anti-ARS-ILD).
    Methods. We evaluated the serum cytokine profiles of 38 patients with PM/DM and compared the cytokine profiles of the non-ILD and ILD subsets as well as the anti-MDA5-ILD and anti-ARS-ILD subsets.
    Results. The myositis intention-to-treat activity index score, which indicates whole disease activity, significantly correlated with serum IL-6, IL-8, TNF-alpha and IP-10. These cytokine levels were significantly higher in the ILD subset than the non-ILD subset and were lower in the ILD subset following treatment. By multivariate analysis, TNF-alpha was the most significant cytokine [P = 0.0006, odds ratio (OR) 1.4, CI 1.1, 2.2] associated with PM/DM with ILD. IL-8 levels were significantly higher in anti-MDA5-ILD than in anti-ARS-ILD, although IL-6, TNF-alpha and IP-10 levels were high in both subsets. IL-8 was the most significant cytokine (P = 0.0006, OR 1.5, CI 1.1, 3.0) associated with anti-MDA5-ILD by multivariate analysis. Moreover, the ratio of IL-4 to IFN-gamma was lower in anti-MDA5-ILD than in anti-ARS-ILD.
    Conclusion. IL-6, IL-8, TNF-alpha and IP-10 are associated with global disease activity in PM/DM. These cytokine levels were high, especially in the ILD subset. Serum IL-8 levels and the balance between IL-4 and IFN-gamma may contribute to the differences in pathophysiology between anti-ARS-ILD and anti-MDA5-ILD.

    ObjectiveAdult-onset Still's disease (AOSD) is a clinical entity with a heterogeneous etiology. We have encountered patients with AOSD who had severe polyarthritis and who fulfilled the classification criteria for rheumatoid arthritis (RA); however, most patients with AOSD typically exhibit mild arthritis. In this study, we proposed 2 clinical subsets of AOSD and investigated the clinically significant characteristics of the 2 subtypes.
    MethodsWe retrospectively analyzed 71 consecutive patients with AOSD. We reviewed the medical records of all patients who were followed up for more than 2 years. We classified all of the patients with AOSD into the following 2 subsets: an RA subtype for patients who met the criteria for RA according to the American College of Rheumatology and a non-RA subtype for patients who did not meet the criteria for RA.
    ResultsOur results indicated that the non-RA subtype was accompanied by severe inflammatory complications, including pleuritis and hemophagocytic syndrome. In addition, the serum ferritin and serum interleukin-18 (IL-18) levels were significantly higher in patients with the non-RA subtype than in those with the RA subtype. Interestingly, only 1 patient with the RA subtype had anti-cyclic citrullinated peptide antibodies and 1 patient with the non-RA subtype had rheumatoid factor. These findings distinguish these patients from patients with true RA.
    ConclusionThere were 2 subsets of patients with AOSD in the examined population. Patients with high levels of IL-18 or ferritin presented with severe systemic inflammatory disorders (non-RA subtype) and patients with low levels of IL-18 or ferritin developed severe arthritis (RA subtype).

    Systemic sclerosis (SSc) is a connective tissue disease characterized by thickening of the skin and tissue fibrosis of the internal organs. Ghrelin is primarily described as a gut hormone, and many studies currently indicate that ghrelin has protective effects in different organs, including the heart, pancreas, lung and liver, resulting from its anti-fibrotic properties. We found decreased levels of ghrelin in the plasma from patients with SSc compared with those from healthy controls. In skin fibroblast cultures, recombinant ghrelin diminished the production of collagen type I. In addition, the mRNA levels of COL1A2 and TGFB genes were significantly decreased by the stimulation of ghrelin. We showed that ghrelin may exert anti-fibrotic effects in the skin fibroblasts from patients with SSc. Because the plasma levels of ghrelin are low in SSc, the administration of ghrelin could be a new strategy for the treatment of SSc. © 2013 Elsevier Inc.

    Objective. Systemic sclerosis (SSc) is an autoimmune disease for which multiple susceptibility genes have been reported. Genome-wide association studies have shown that large numbers of susceptibility genes are shared among autoimmune diseases. Recently, our group identified 9 novel susceptibility genes associated with rheumatoid arthritis (RA) in a Japanese population. The aim of this study was to elucidate whether the 18 genes that displayed associations or suggestive associations for RA in our previous study are associated with SSc in Japanese.
    Methods. We performed an association study that included 415 patients with SSc and 16,891 control subjects, followed by a replication study that included 315 patients and 21,054 control subjects. The 18 markers reported to display association with RA were analyzed for their associations with SSc in the first study, and 5 markers were further analyzed in the replication study. The inverse variance method was used to evaluate the associations of these markers with SSc in a combined study.
    Results. In the phospholipase D4 gene (PLD4), rs2841277 displayed a significant association with SSc in Japanese patients (P = 0.00017). We observed that rs2841280 in exon 2 of PLD4 was in strong linkage disequilibrium with rs2841277 and introduced an amino acid alteration. We also observed associations between SSc and rs6932056 in TNFAIP3 and rs2280381 in IRF8 (P = 0.0000095 and P = 0.0030, respectively), both of which displayed associations with SSc in a European population.
    Conclusion. We determined that PLD4 is a novel susceptibility gene for SSc in Japanese, thus confirming the involvement of PLD4 in autoimmunity. Associations between SSc and TNFAIP3 or IRF8 were also detected in our Japanese population. SSc and RA appear to share relatively large proportions of their genetic backgrounds.

    Objective. The complication of interstitial lung disease (ILD) in polymyositis/dermatomyositis (PM/DM) is associated with anti-aminoacyl-transfer RNA synthetase (anti-aaRS) antibody or anti-melanoma differentiation-associated gene 5 (anti-MDA-5) antibody positivity. Anti-MDA-5 antibody is associated with clinically amyopathic DM and fatal outcome due to rapidly progressive ILD in Asian populations. The association between genetic factors and anti-MDA-5 antibody-positive DM is unclear. This study was undertaken to investigate the HLA-DRB1 genotype in patients with anti-MDA-5 antibody-positive DM.
    Methods. We examined genetic differences among 17 patients with anti-MDA-5 antibody-positive DM, 33 patients with anti-aaRS antibody-positive PM/DM, 33 patients with PM/DM without anti-aaRS antibody or ILD, and 265 healthy controls.
    Results. The frequencies of HLA-DRB1*0101 and DRB1*0405 were 29% and 71%, respectively, in patients with anti-MDA-5 antibody-positive DM, which were higher than the frequencies in healthy controls (10% and 25%, respectively). Among the 17 patients with anti-MDA-5 antibody-positive DM, 16 (94%) harbored either the DRB1*0101 or DRB1*0405 allele. The com-bined frequency of the DRB1*0101 allele and the DRB1*0405 allele was significantly higher in patients with anti-MDA-5 antibody-positive DM than in patients with PM/DM without anti-aaRS antibody or ILD, with an odds ratio (OR) of 42.7 (95% confidence interval [95% CI] 4.9-370.2) (P = 1.1 x 10(-5)), or in patients with anti-aaRS antibody-positive PM/DM (OR 13.3 [95% CI 1.6-112.6], P = 4.5 x 10(-3)).
    Conclusion. Our findings indicate that HLA-DRB1*0101/*0405 is associated with susceptibility to anti-MDA-5 antibody-positive DM in the Japanese population.

    Objective. Interstitial lung disease (ILD) is a serious complication of SSc. We aimed to identify markers associated with SSc-related ILD.
    Methods. RNA was prepared from the peripheral blood mononuclear cells of 14 SSc patients, divided into four different RNA pools according to the presence or absence of ILD and to the treatment, and subjected to microarray analysis. Real-time quantitative PCR was used to confirm the microarray results in 43 SSc patients, 42 autoimmune controls and 10 healthy controls. Genomic DNA samples were collected from 149 patients with SSc (70 in Hokkaido and 79 in Tokyo) who underwent a high-resolution CT for the evaluation of ILD and from 230 healthy controls. Genotyping was performed using sequence-specific primers.
    Results. The microarray analysis revealed HLA-DRB5 to be the only gene commonly up-regulated in patients with ILD compared with those without ILD in both comparison groups. High expression levels of HLA-DRB5 in SSc patients with ILD were confirmed by real-time quantitative PCR. The prevalence of HLA-DRB5 gene carriers increased in the SSc patients with ILD relative to those without ILD or to healthy controls in both cohorts. Among the four detected alleles, the HLA-DRB5*01:05 allele was significantly more frequent in SSc patients with ILD than in SSc patients without ILD or in healthy controls. These associations were confirmed in the second cohort.
    Conclusion. HLA-DRB5 was highly expressed in PBMCs from patients with SSc-related ILD. The HLA-DRB5*01:05 allele is a risk factor for ILD in patients with SSc.

    Objective. The aim of this study was to investigate the precise clinical characteristics and to analyse the association between the anti-MDA5 antibody (anti-MDA5ab) titre and disease status in patients with anti-MDA5ab-positive DM.
    Methods. Twenty-seven patients who presented with DM and were positive for the anti-MDA5ab were enrolled. The association between the clinical manifestations and the clinical parameters, including the anti-MDA5ab, was analysed.
    Results. The complication of rapidly progressive interstitial lung disease (RP-ILD) occurred in 20 (74%) patients. The frequencies of fatal outcome, relapse and malignancy were 33, 4 and 4%, respectively. Remarkably, a fatal outcome occurred within the first 6 months. Compared with six non-RP-ILD patients, elderly age at onset, severely involved pulmonary function and high levels of serum ferritin were present in 20 RP-ILD patients with anti-MDA5ab. Alveolar-arterial oxygen difference (AaDO(2)) epsilon 32 mmHg and ferritin epsilon 828 ng/ml at admission were poor prognostic factors in RP-ILD patients with anti-MDA5ab-positive DM. The median value of the anti-MDA5ab titre on admission was higher in patients who later died than in those who survived. The efficacy of treatment was indicated by the anti-MDA5ab, ferritin and IL-18 concentrations. The decline index of the anti-MDA5ab titre after treatment was lower in the subset of patients who died than in the subset of patients who lived. Sustained high levels of anti-MDA5ab, ferritin and IL-18 were present in the patients who died.
    Conclusion. Anti-MDA5ab titre and ferritin and IL-18 concentrations are useful for the evaluation of the response to treatment and the status of ILD in patients with anti-MAD5ab-positive DM.

    Interstitial lung disease (ILD) is a noteworthy condition in the treatment of systemic sclerosis (SSc) because of its associated mortality and morbidity; however, the efficacy of various treatments for ILD has been controversial in previous reports. In this study, we examined the efficacy and safety of intravenous cyclophosphamide (IVCY) pulse therapy with prednisolone (PSL) for the treatment of ILD with SSc. A total of 121 patients with SSc were screened and evaluated for ILD, using high-resolution computed tomography of the chest, pulmonary function testing, and bronchoalveolar lavage. Thirteen patients with active ILD were enrolled in this study. The treatment protocol for ILD was 0.4 g/m(2) of body surface area of IVCY monthly plus 0.8 mg/kg of body weight of PSL daily. Two to six doses of IVCY were administered, depending on the remission of ILD. Initial PSL doses were maintained for a month and then gradually tapered to 10 mg daily. An activity index of ILD showed improvements in all patients in the 12 months after the initial intervention; however, four patients experienced recurrence of ILD after 24 months, and one additional patient had recurrence of ILD after 36 months. Seven patients reached the 48-month point with no recurrence of ILD. This long observational study for 48 months showed the efficacy of IVCY with PSL for active alveolitis in the first year. However, because five patients had recurrence of ILD more than 1 year after the treatment, it would be necessary to consider maintenance therapy for ILD beyond 1 year.

    Systemic sclerosis (SSc) is a chronic disease of unknown etiology that is characterized by multiple tissue fibrosis. Transforming Growth Factor-beta (TGF-beta) is thought to be the most important mediator that induces fibrosis. However, the molecular mechanisms by which fibrosis is induced have not been fully elucidated. In this study, the role of activin, a member of the TGF-beta superfamily, was investigated in the pathogenesis of fibrosis in SSc. Serum activin A levels in patients with SSc were measured by ELISA, and the expression of the activin receptor type IB (ACVRIB/ALK4) and the activity of the signaling pathway via ACVRIB/ALK4 were investigated using western blotting. To evaluate a potential therapeutic strategy for SSc, we also attenuated the ACVRIB/ALK4 pathway using an inhibitor. Serum activin A levels were significantly higher in SSc patients than in normal controls. Activin A and ACVRIB/ALK4 expression were also higher in cultured SSc fibroblasts. Activin A stimulation induced phosphorylation of Smad2/3 and CTGF expression in SSc fibroblasts. Procollagen production and Col1 alpha mRNA also increased upon stimulation by activin A. The basal level of Smad2/3 phosphorylation was higher in cultured SSc fibroblasts than in control cells, and treatment with the ALK4/5 inhibitor SB431542 prevented phosphorylation of Smad2/3 and CTGF expression. Furthermore, production of collagen was also induced by activin A. Activin A-ACVRIB/ALK4-Smad-dependent collagen production was augmented in SSc fibroblasts, suggesting the involvement of this signaling mechanism in SSc. Inhibition of the activin A-ACVRIB/ALK4-Smad pathway would be a new approach for the treatment of SSc. (C) 2010 Elsevier Ltd. All rights reserved.

    Dermatomyositis (DM) is occasionally complicated by interstitial lung disease. Acute/subacute interstitial pneumonia (A/SIP) with DM is intractable and life threatening. Clinically amyopathic dermatomyositis (C-ADM) is also reported to be complicated with A/SIP, especially in those patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody. In the present cases, we indicate that serum ferritin level correlated with activity of A/SIP with DM. Two patients, a 65-year-old woman and a 30-year-old woman, were diagnosed with anti-MDA5 antibody-associated A/SIP with DM. Serum ferritin was high, 1600 and 770 mg/dl, respectively, on admission. Immunosuppressive therapy ameliorated A/SIP in both cases. Similarly, serum ferritin was also decreasing. However, A/SIP was recurrent and progressive, and serum ferritin was also increasing again in one case. In conclusion, serum ferritin correlates with disease activity of anti-MDA5 antibody-associated A/SIP with DM. Intensity of treatment may be decided according to serum ferritin level.

    Objective. To determine whether IL-18 is involved in the inflammation of DM and PM.
    Methods. Thirty-three patients with DM were enrolled in this study, including 25 with interstitial lung disease (ILD). In addition, 16 patients with PM were enrolled, including 6 with ILD. All patients were admitted to our hospital as a result of their condition requiring treatment, and clinical laboratory data including serum IL-18 were recorded on admission.
    Results. Serum IL-18 was significantly (P < 0.0001) higher in both DM and PM patients than in healthy controls (n = 30). Serum ferritin and IL-18 were significantly (P = 0.003 and 0.0044, respectively) higher in DM than in PM patients. Additionally, ferritin and IL-18 were significantly (P = 0.023 and 0.034, respectively) higher in DM patients with ILD than in DM patients without ILD. Significant positive correlations were found between creatine kinase (CK) and ferritin (r(s) = 0.39, P = 0.024); CK and IL-18 (r(s) = 0.48, P = 0.005); and IL-18 and ferritin (r(s) = 0.54, P = 0.0012) in the DM group as a whole. These findings were different for the DM plus ILD subgroup: significant positive correlations were found between CK and ferritin (r(s) = 0.40, P = 0.047); CK and IL-18 (r(s) = 0.63, P = 0.0008); and IL-18 and ferritin (r(s) = 0.41, P = 0.042).
    Conclusion. Serum IL-18 was strikingly elevated in patients with DM and was associated particularly with disease activity and ILD complication in DM.

    The objective of this study was to explore the association of single nucleotide polymorphisms (SNPs) of the CD244 gene with several clinical features of systemic lupus erythematosus (SLE). Two hundred and forty-three patients with SLE and 369 healthy controls were enrolled. Two SNPs (rs6682654 and rs3766379) in the CD244 gene were determined by allelic discrimination using a specific TaqMan probe. Only SNP rs3766379 was significantly associated with susceptibility to SLE [P = 0.009; odds ratio (OR) 1.28; 95% confidence interval (CI) 1.04-1.57]. The association was preferentially observed in subsets of SLE patients with nephritis and neuropsychiatric lupus. The frequency of the rs6682654 C allele was strongly associated with nephritis and neuropsychiatric lupus (P = 0.00065; OR 1.99; 95% CI 1.34-2.95, and P = 1.6 x 10(-7); OR 3.47; 95% CI 2.12-5.70, respectively), as was the frequency of the rs3766379 T allele (P = 0.0014; OR 1.86; 95% CI 1.27-2.71, and P = 2.6 x 10(-7); OR 3.15; 95% CI 2.00-4.96, respectively). In this study, an SNP of the CD244 gene was associated with susceptibility to SLE. There was a strikingly strong association in SLE patients with nephritis and neuropsychiatric lupus, suggesting that this genetic marker could predict involvement of those severe complications.

    Methods. Fourteen patients who presented with anti-MDA5 antibody and 10 patients with anti-aminoacyl-tRNA synthetase (ARS) antibody were enrolled. All patients were diagnosed as having DM with ILD. Clinical manifestations in the patients with anti-MDA5 antibody were compared with those in the patients with anti-ARS antibody.
    Results. The frequencies of acute/subacute interstitial pneumonia (A/SIP) and fatal outcome were significantly higher in the subset with anti-MDA5 antibody. The creatine kinase (CK) value was significantly lower and the gamma-glutamyl transpeptidase and ferritin values were significantly higher in the subset with anti-MDA5 antibody. Significant correlations were found between PaO(2)/F(i)O(2) and ferritin (r(s) = -0.59, P = 0.035), alveolar-arterial oxygen difference (A-aDO(2)) and KL-6 (r(s) = 0.73, P = 0.016) and A-aDO(2) and ferritin (r(s) = 0.66, P = 0.013) in the subset with anti-MDA5 antibody. The most significant prognostic factor was ferritin. The cumulative survival rate was significantly lower (P < 0.0001) in the subset with ferritin epsilon 1600 ng/ml than that in the subset with ferritin < 1600 ng/ml in anti-MDA5 antibody-associated ILD.
    Conclusion. Both serum ferritin and anti-MDA5 antibody are powerful indicators for the early diagnosis of A/SIP with DM. Ferritin also predicts disease severity and prognosis for patients with anti-MDA5 antibody. Intensive treatment should be administered to cases that have anti-MDA5 antibody-associated ILD with DM showing hyperferritinaemia, especially if the ferritin level is epsilon 1600 ng/ml.

    Objectives. Acute/subacute interstitial pneumonia (A/SIP) is an intractable and fatal complication of DM. Since a useful indicator predicting the complication of A/SIP has not been found, the aim of this study was to determine whether serum ferritin is a potential predictive indicator of the occurrence of A/SIP in 64 patients with DM.
    Methods. Of the total patients enrolled, 19 had A/SIP, 24 had chronic interstitial pneumonia and 21 were without interstitial lung disease (ILD). Clinical manifestations and laboratory data were obtained from medical records on admission.
    Results. Serum ferritin levels were extremely high in patients with DM with A/SIP. It was significantly higher in DM with A/SIP than that in DM without A/SIP (median 790 vs 186 ng/ml; P<0.0001). The cumulative survival rate for 6 months was 62.7% in patients with DM with A/SIP. Moreover, the cumulative survival rate was significantly (P = 0.016) lower in the group with ferritin levels >= 1500 ng/ml than the rate in the group with ferritin levels < 1500 ng/ml.
    Conclusions. Serum ferritin can be useful as a predictor of the occurrence of A/SIP and correlates with the prognosis of A/SIP in DM. The intensive treatment using combination therapy with various immunosuppressant agents should be chosen for patients with ILD with DM showing hyperferritinaemia, especially levels > 1500 ng/ml.

    Objectives: To validate the association of a single nucleotide polymorphism (SNP) of the connective tissue growth factor gene (CTGF) with susceptibility to systemic sclerosis (SSc) in the Japanese population.
    Methods: 395 Japanese patients with SSc, 115 patients with rheumatoid arthritis and 269 healthy Japanese volunteers were enrolled in the study. An SNP (rs6918698) at -945 bp from the start codon in the promoter region of the CTGF gene was determined by allelic discrimination with the use of a specific TaqMan probe.
    Results: The G allele showed a significantly higher frequency in patients with SSc than in controls (p<0.001; odds ratio 1.5; 95% confidence interval 1.2 to 1.9). In particular, the clinical subsets of SSc showed a more significant association between the G allele and diffuse cutaneous SSc (p<0.001) and the presence of interstitial lung disease (p<0.001), the presence of anti-topoisomerase I antibody (p<0.001) and anti-U1RNP antibody (p = 0.010). Association analyses using the genotype of the SNP yielded results similar to those of analyses using the allele.
    Conclusions: This study confirms the association between an SNP in the CTGF gene and susceptibility to SSc, especially in the presence of diffuse cutaneous SSc, interstitial lung disease and anti-topoisomerase I antibody. The results strongly suggest that this SNP may be a powerful indicator of severe skin and lung involvement in patients with SSc.

    全身性強皮症(SSc)は血管内皮障害および線維化を特徴とする疾患である。単球・マクロファージがその病態に重要な役割を果たしていることは知られているが、SSc特異的単球・マクロファージの同定には至っていない。本研究は、in vitroで分化誘導したマクロファージの網羅的遺伝子解析から、異なる誘導因子によるマクロファージ分化誘導のmaster regulatorを同定し、それらを元にmaster regulator抽出アルゴリズムを構築する。構築したアルゴリズムを用いてSSc単球RNA-seq及び末梢血単核球single cell RNA-seqデータを解析し、SSc特異的単球・マクロファージにおけるmaster regulatorを同定することを目的としている。
    本年度は、まず各誘導マクロファージの遺伝子発現の網羅的解析を行う際のコンディション調整を行った。末梢血単核球を密度勾配法にて抽出し、magnetic beadsでCD14+単球を単離し、CSF-1を初めとする各種成長因子、サイトカイン、ケモカイン添加のもと培養し、total RNAを抽出する。この過程において、誘導因子の濃度変化や培養時間の調整により、cell viability等を検討し、最適な誘導条件を設定した。さらに、既報を参考に、発現変動遺伝子の抽出、pathway解析、データの統合といったRNA-seqおよびcsRNA-seqデータの解析手法を習得した。
    今後は、早急に異なる因子により誘導したマクロファージの網羅的遺伝子解析を行い、master regulatorの同定を行いたいと考えている。
