RESUMEN

Emanating from a discrete category within the lympho-hematopoietic tumor system, as established by the World Health Organization in 2008, the blastic plasmacytoid dendritic cell neoplasm constitutes an uncommon malignant hematological disorder. It is routinely misidentified on account of its conspicuous dermatological manifestation, yet may insidiously permeate bone marrow and lymph nodes, involving peripheral blood and diverse extra-nodal tissues. Instances of mammary gland encroachment are extraordinarily infrequent. The current document delineates a case of a 14-year-old female patient contending with blastic plasmacytoid dendritic cell neoplasm, whose primary symptom was a mammary nodule, and whose breast and bone marrow/blood involvement were synchronous, in attempt to increase clinical vigilance.

RESUMEN

Tyrosine kinase inhibitors, such as gefitinib, are currently widely used as targeted therapeutics for non­small cell lung cancer (NSCLC). Although drug resistance has become a major obstacle to successful treatment, mechanisms underlying resistance to gefitinib remain unclear. Therefore, the present study aimed to investigate the impact of adjunctive cucurbitacin B (CuB) on gefitinib resistance (GR) in the PC9 cell line, including identifying underlying mechanisms. Reverse transcription­quantitative PCR demonstrated significant downregulation of microRNA (miR)­17­5p expression in GR PC9 cells (PC9/GR), and this could be reversed by CuB. During combination treatment with CuB and gefitinib at IC25, PC9/GR cell proliferation was downregulated, and apoptosis was upregulated. The presence of a miR­17­5p inhibitor negated the effects of CuB and gefitinib, whereas the presence of a miR­17­5p mimic enhanced them. Luciferase assays demonstrated that the hypothetical target gene, signal transducer and activator of transcription 3 (STAT3), was directly targeted by miR­17­5p. Moreover, significant elevation of the STAT3 protein and phosphorylation levels in PC9/GR cells was reversed by the addition of CuB, despite a lack of change in STAT3 transcription level. During combined treatment with CuB and gefitinib at IC25, the STAT3 protein expression was negatively associated with the expression of miR­17­5p. Overexpression of STAT3 increased proliferation and decreased apoptosis and the protein levels of apoptosis­related factors cleaved caspase­3 and cleaved caspase­9 of PC9/GR cells. Findings indicated that STAT3 protein and phosphorylation levels became elevated in response to gefitinib, and that CuB­induced miR­17­5p expression led to STAT3 degradation, thereby ameliorating GR. In summary, CuB reduced the proliferation of GR PC9 cells by modulating the miR­17­5p/STAT3 axis, and may represent a promising potential novel strategy for the reversal of GR.

RESUMEN

BACKGROUND: The 2019 Coronavirus (COVID-19) pandemic poses a huge threat internationally; however, the role of the host immune system in the pathogenesis of COVID-19 is not well understood. METHODS: Cytokine and chemokine levels and characterisation of immune cell subsets from 20 COVID-19 cases after hospital admission (17 critically ill and 3 severe patients) and 16 convalescent patients were determined using a multiplex immunoassay and flow cytometry, respectively. RESULTS: IP-10, MCP-1, MIG, IL-6, and IL-10 levels were significantly higher in acute severe/critically ill patients with COVID-19, whereas were normal in patients who had reached convalescence. CD8 T cells in severe and critically ill COVID-19 patients expressed high levels of cytotoxic granules (granzyme B and perforin)and was hyperactivated as evidenced by the high proportions of CD38. Furthermore, the cytotoxic potential of natural killer (NK) cells, and the frequencies of myeloid dendritic cells and plasmacytoid dendritic cells was reduced in patients with severe and critical COVID-19; however, these dysregulations were found to be restored in convalescent phases. CONCLUSION: Thus, elicitation of the hyperactive cytokine-mediated inflammatory response, dysregulation of CD8 T and NK cells, and deficiency of host myeloid and plasmacytoid DCs, may contribute to COVID-19 pathogenesis and provide insights into potential therapeutic targets and strategies.

RESUMEN

OBJECTIVE: To analyze the relationship between T cell subsets and clinical data. METHODS: mononuclear cells were collected from 103 patients with acute leukemia (AL) and 28 healthy volunteers, and percentage changes of CD3+CD4+, CD3+CD8+ and CD4+ CD25+ Foxp3+ cell subsets were assayed by flow cytometory. Relationship between the T subsets and clinical features of the patients was analyzed. RESULTS: Ratio of CD3+ T cells decreased more significantly in patients with >50% blast cells than that in patients with <50% blast cells, while the ratio of Treg between the 2 groups was not significantly different. Treg increased more statistically significantly in the patients with CD34+ leukemia cell than that with CD34- leukemia cells. In constrast to the relationship between prognosis and immune cells in the patients from 3 groups (low, intermediate and high-risk group) it was found that Treg cells increased more significantly in high-risk group than that in low-risk group. By continuously monitoring immune cells in 18 patients, it was found that Treg cells gradually increased during the first 3 courses of chemotherapy, then began to decreased in the 4th course, finally approached gradually to the normal value in the 6th course, and this change correlated with the clinical remission after chemotherapy. Treg cell number in the patients with AL was significantly higher than that in healthy controls, and Treg cell number during the onset and recurrence was significantly higher than that in the period of complete remission (continuous remission for over 6 months). Compared with the changes of immune cell number between different types of disease, it was found that Treg cells were increased more significantly in acute myeloid leukemia (AML) than that in acute lymphoblastic leukemia (ALL). Proportion of Treg cells, Treg/CD4 decreased more significantly after the 1st course of chemotherapy in the group with complete remission (CR) than that in the group without CR. The complete remission rate and recurrence rate were 68.9% and 20% respectively in the group with >10% Treg cells, while the complete remission rate and recurrence rate were 85.7% and 7.69% respectively in the group with.<10% Treg cells. In comparison of the 6 recurrent patients with 32 patients with sustained CR, it was found that the ratio of Treg cells and Treg/CD4 was increased more significantly in the patients with relapse than that with CR and in control group. CONCLUSION: Dynamic change of Treg cells in the peripheral blood was closely related with clinical feature, recurrence and prognosis in the patients with acute leukemia.

RESUMEN

BACKGROUND: High-mobility group AT-hook 2 (HMGA2) may serve as an architectural transcription factor, and it can regulate a range of normal biological processes including proliferation and differentiation. Upregulation of HMGA2 expression is correlated to the undifferentiated phenotype of immature leukaemic cells. However, the underlying mechanism of HMGA2-dependent myeloid differentiation blockage in leukaemia is unknown. METHODS: To reveal the role and mechanism of HMGA2 in differentiation arrest of myeloid leukaemia cells, the quantitative expression of HMGA2 and homeobox A9 (HOXA9) was analysed by real-time PCR (qRT-PCR). The regulatory function of HMGA2 in blockage of differentiation in human myeloid leukaemia was investigated through in vitro assays (XTT assay, May-Grünwald-Giemsa, flow cytometry analysis and western blot). RESULTS: We found that the expression of HMGA2 and HOXA9 was reduced during the process of granulo-monocytic maturation of acute myeloid leukaemia (AML) cells, knockdown of HMGA2 promotes terminal (granulocytic and monocytic) differentiation of myeloid leukaemia primary blasts and cell lines, and HOXA9 was significantly downregulated in leukaemic cells with knockdown of HMGA2. Downregulation of HOXA9 in myeloid leukaemia cells led to increased differentiation capacity in vitro. CONCLUSIONS: Our data suggest that increased expression of HMGA2 represents a possible new mechanism of myeloid differentiation blockage of leukaemia. Aberrant expression of HMGA2 may enhance HOXA9-dependent leukaemogenesis and myeloid leukaemia phenotype. Disturbance of the HMGA2-HOXA9 pathway is probably a therapeutic strategy in myeloid leukaemia.

RESUMEN

Previous studies have reported that regulatory T cells (Tregs), which are physiologically engaged in the maintenance of immunological self-tolerance, have a critical role in the regulation of the antitumor immune response. Targeting Tregs has the potential to augment cancer vaccine approaches. The current study therefore aimed to evaluate the role of cytokine-induced killer (CIK) cell infusion in modulating Tregs in patients with non-small cell lung cancer (NSCLC). A total of 15 patients with advanced NSCLC were treated by an infusion of CIK cells derived from autologous peripheral blood mononuclear cells (PBMCs). By using flow cytometry and liquid chip analysis, subsets of T cells and natural killer (NK) cells in peripheral blood, and plasma cytokine profiles in the treated patients, were analyzed at 2 and 4 weeks after CIK cell infusion. Cytotoxicity of PBMCs (n=15) and NK cells (n=6) isolated from NSCLC patients was evaluated before and after CIK cell therapy. Progression-free survival (PFS) and overall survival (OS) were also assessed. Analysis of the immune cell populations before and after treatment showed a significant increase in NK cells (P<0.05) concomitant with a significant decrease in Tregs (P<0.01) at 2 weeks post-infusion of CIK cells compared with the baseline. NK group 2D receptor (NKG2D) expression on NK cells was also significantly increased at 2 weeks post-infusion compared with the baseline (P<0.05). There was a positive correlation between NKG2D expression and the infusion number of CIK cells (P<0.05). When evaluated at 2 weeks after CIK cell therapy, the cytotoxicity of PBMCs and isolated NK cells was significantly increased compared with the baseline (P<0.01 and P<0.05). Correspondingly, plasma cytokine profiles showed significant enhancement of the following antitumor cytokines: Interferon (IFN)-γ (P<0.05), IFN-γ-inducible protein 10 (P<0.01), tumor necrosis factor-α (P<0.001), granulocyte-macrophage colony-stimulating factor (P<0.01), monocyte chemotactic protein-3 (P<0.01) and interleukin-21 (P<0.05) at 2 weeks post-infusion, compared with the baseline. At the same time, the expression of transforming growth factor-ß1, which is primarily produced by Tregs, was significantly decreased compared with the baseline (P<0.05). Median PFS and OS in the CIK cell treatment group were significantly increased compared with the control group (PFS, 9.98 vs. 5.44 months, P=0.038; OS, 24.17 vs. 20.19 months, P=0.048). No severe side-effects were observed during the treatment period. In conclusion, CIK cell therapy was able to suppress Tregs and enhance the antitumor immunity of NK cells in advanced NSCLC patients. Therefore, CIK cell treatment may improve PFS and OS in patients with advanced NSCLC. CIK cell infusion may have therapeutic value for patients with advanced NSCLC, as a treatment that can be combined with chemotherapy and radiotherapy.

RESUMEN

A new type of drug delivery system (DDS) based on single-walled carbon nanotubes (SWNTs) for controlled-release of the anti-cancer drug Paclitaxel (PTX) was constructed in this study. Chitosan (CHI) was non-covalently attached to the SWNTs to improve biocompatibility. Biocompatible hyaluronan was also combined to the outer CHI layer to realise the specific targeting property. The results showed that the release of PTX was pH-triggered and was better at lower pH (pH5.5). The modified SWNTs showed a significant improvement in intracellular reactive oxygen species (ROS), which may have enhanced mitogen-activated protein kinase activation and further promoted cell apoptosis. The results of western blotting indicated that the apoptosis-related proteins were abundantly expressed in A549 cells. Lactate dehydrogenase (LDH) release assay and cell viability assay demonstrated that PTX-loaded SWNTs could destroy cell membrane integrity, thus inducing lower cell viability of the A549 cells. Thus, this targeting DDS could effectively inhibit cell proliferation and kill A549 cells, is a promising system for cancer therapy.

RESUMEN

Delivery of amphiphobic drugs (insoluble in both water and oil) has been a great challenge in drug delivery. SNX-2112, a novel inhibitor of Hsp90, is a promising drug candidate for treating various types of cancers; however, the insolubility greatly limits its clinical application. This study aimed to build a new type of drug delivery system using single-walled carbon nanotubes (SWNTs) for controllable release of SNX-2112; chitosan (CHI) was non-covalently added to SWNTs to improve their biocompatibility. SWNTs-CHI demonstrated high drug-loading capability; the release of SNX-2112 was pH triggered and time related. The intracellular reactive oxygen species of SWNTs-CHI increased, compared with that of SWNTs, leading to higher mitogen-activated protein kinase and cell apoptosis. The results of western-blotting, lactate dehydrogenase (LDH) release assay, and cell viability assay analyses indicated that apoptosis-related proteins were abundantly expressed in K562 cells and that the drug delivery system significantly inhibited K562 cells. Thus, SWNT-CHI/SNX-2112 shows great potential as a drug delivery system for cancer therapy.

RESUMEN

BACKGROUND: Interstitial pneumonia in connective tissue diseases (CTD-IP) featuring inflammation and fibrosis is a leading cause of death in CTD-IP patients. The related autoimmune lung injury and disturbed self-healing process make conventional anti-inflammatory drugs ineffective. Equipped with unique immunoregulatory and regenerative properties, mesenchymal stem cells (MSCs) may represent a promising therapeutic agent in CTD-IP. In this study, we aim to define the immunopathology involved in pulmonary exacerbation during autoimmunity and to determine the potential of MSCs in correcting these disorders. METHODS: Lung and blood specimens, bronchoalveolar lavage fluid cells collected from CTD-IP patients, and human primary lung fibroblasts (HLFs) from patients pathologically diagnosed with usual interstitial pneumonia (UIP) and healthy controls were analyzed by histology, flow cytometry and molecular biology. T cell subsets involved in the process of CTD-IP were defined, while the regulatory functions of MSCs isolated from the bone marrow of normal individuals (HBMSCs) on cytotoxic T cells and CTD-UIP HLFs were investigated in vitro. RESULTS: Higher frequencies of cytotoxic T cells were observed in the lung and peripheral blood of CTD-IP patients, accompanied with a reduced regulatory T cell (Treg) level. CTD-UIP HLFs secreted proinflammatory cytokines in combination with upregulation of α-smooth muscle actin (α-SMA). The addition of HBMSCs in vitro increased Tregs concomitant with reduced cytotoxic T cells in an experimental cell model with dominant cytotoxic T cells, and promoted Tregs expansion in T cell subsets from patients with idiopathic pulmonary fibrosis (IPF). HBMSCs also significantly decreased proinflammatory chemokine/cytokine expression, and blocked α-SMA activation in CTD-UIP HLFs through a TGF-ß1-mediated mechanism, which modulates excessive IL-6/STAT3 signaling leading to IP-10 expression. MSCs secreting a higher level of TGF-ß1 appear to have an optimal anti-fibrotic efficacy in BLM-induced pulmonary fibrosis in mice. CONCLUSIONS: Impairment of TGF-ß signal transduction relevant to a persistent IL-6/STAT3 transcriptional activation contributes to reduction of Treg differentiation in CTD-IP and to myofibroblast differentiation in CTD-UIP HLFs. HBMSCs can sensitize TGF-ß1 downstream signal transduction that regulates IL-6/STAT3 activation, thereby stimulating Treg expansion and facilitating anti-fibrotic IP-10 production. This may in turn block progression of lung fibrosis in autoimmunity.

RESUMEN

BACKGROUND: There is limited information on a special subtype of Acute myeloid leukemia (AML) characterized by >20% myeloblasts and >20% abnormal promyelocytes in bone marrow and peripheral blood. OBJECTIVE: The objective of the present investigation was to explore the clinical and laboratory features of seven patients with AML-M2/M3. METHOD: We retrospectively assessed cell morphology, cytochemistry, immunophenotype, cytogenetics, and clinical features of seven patients with this rare subtype of AML. RESULTS: All seven cases had thrombocytopenia, coagulation abnormalities, >20% myeloblasts and abnormal promyelocytes. The PML/RARα fusion gene was present in six patients and two patients presented a mixed PML/RARα and AML1/ETO genotype. Five cases achieved CR and two cases did not achieve remission and one case transform into AML-M2 after CR1. CONCLUSIONS: The clinical and laboratory features of seven patients with AML-M2/M3 are demonstrated in the present study, providing information on the FAB sub-classification.

RESUMEN

The aberrant activation of the JAK2/STAT3 signaling in immature myeloid dendritic cells (DCs) is associated with immune tolerance and poor antitumor immunity. The objective of this study was to test the hypothesis that Cucurbitacin B (CuB), a selective inhibitor of JAK2/STAT3 signaling, could promote DC differentiation and improve antitumor immunity. Twelve patients with advanced lung cancers were treated orally with CuB daily for 7 consecutive days. The frequency of peripheral blood myeloid DCs and immature myeloid cells (imCs) in those patients and healthy controls was characterized longitudinally by flow cytometry. The effect of CuB on the differentiation of DCs and p53-specific T responses was evaluated in vitro. The percentages of Lin(-)DR(-)CD33(+) imCs and Lin(-)DR(+)CD33(+) DCs were significantly different between patients with lung cancers and healthy controls (1.55% vs. 0.82%, p=0.002; 0.60% vs. 1.90%, p=0.000). Treatment with CuB significantly increased the frequency of Lin(-)DR(+)CD33(+), but reduced the frequency of Lin(-)DR(-)CD33(+) in patients with lung cancers (p<0.05). Treatment with CuB induced the differentiation of DCs cocultured with tumor cells 16HBE/BPDE and enhanced the sensitivity of 16HBE/BPDE cells to p53-specific CTL by inhibiting the JAK2/STAT3 activation, but also enhancing the interferon-γ-related STAT1 activation in 16HBE/BPDE cells. CuB significantly reduced the frequency of imCs in patients with lung cancers and enhanced the effect of p53-specific CTL on tumor 16HBE/BPDE cells.
