Human Cytotoxic T Lymphocytes Form Dysfunctional Immune Synapses with B Cells Characterized by Non-Polarized Lytic Granule Release.

Suppression of the cytotoxic T cell (CTL) immune response has been proposed as one mechanism for immune evasion in cancer. In this study,we have explored the underlying basis for CTL suppression in the context of B cell malignancies. We document that human B cells have an intrinsic ability to resist killing by freshly isolated cytotoxic T cells (CTLs),but are susceptible to lysis by IL-2 activated CTL blasts and CTLs isolated from immunotherapy-treated patients with chronic lymphocytic leukemia (CLL). Impaired killing was associated with the formation of dysfunctional non-lytic immune synapses characterized by the presence of defective linker for activation of T cells (LAT) signaling and non-polarized release of the lytic granules transported by ADP-ribosylation factor-like protein 8 (Arl8). We propose that non-lytic degranulation of CTLs are a key regulatory mechanism of evasion through which B cells may interfere with the formation of functional immune synapses by CTLs.

Mast cells are permissive for rhinovirus replication: potential implications for asthma exacerbations.

BACKGROUND Human rhinoviruses (HRVs) are a major trigger of asthma exacerbations,with the bronchial epithelium being the major site of HRV infection and replication. Mast cells (MCs) play a key role in asthma where their numbers are increased in the bronchial epithelium with increasing disease severity. OBJECTIVE In view of the emerging role of MCs in innate immunity and increased localization to the asthmatic bronchial epithelium,we investigated whether HRV infection of MCs generated innate immune responses which were protective against infection. METHODS The LAD2 MC line or primary human cord blood-derived MCs (CBMCs) were infected with HRV or UV-irradiated HRV at increasing multiplicities of infection (MOI) without or with IFN-β or IFN-λ. After 24 h,innate immune responses were assessed by RT-qPCR and IFN protein release by ELISA. Viral replication was determined by RT-qPCR and virion release by TCID50 assay. RESULTS HRV infection of LAD2 MCs induced expression of IFN-β,IFN-λ and IFN-stimulated genes. However,LAD2 MCs were permissive for HRV replication and release of infectious HRV particles. Similar findings were observed with CBMCs. Neutralization of the type I IFN receptor had minimal effects on viral shedding,suggesting that endogenous type I IFN signalling offered limited protection against HRV. However,augmentation of these responses by exogenous IFN-β,but not IFN-λ,protected MCs against HRV infection. CONCLUSION AND CLINICAL RELEVANCE MCs are permissive for the replication and release of HRV,which is prevented by exogenous IFN-β treatment. Taken together,these findings suggest a novel mechanism whereby MCs may contribute to HRV-induced asthma exacerbations. View Publication

Efficient derivation of lateral plate and paraxial mesoderm subtypes from human embryonic stem cells through GSKi-mediated differentiation.

The vertebrae mesoderm is a source of cells that forms a variety of tissues,including the heart,vasculature,and blood. Consequently,the derivation of various mesoderm-specific cell types from human embryonic stem cells (hESCs) has attracted the interest of many investigators owing to their therapeutic potential in clinical applications. However,the need for efficient and reliable methods of differentiation into mesoderm lineage cell types remains a significant challenge. Here,we demonstrated that inhibition of glycogen synthase kinase-3 (GSK-3) is an essential first step toward efficient generation of the mesoderm. Under chemically defined conditions without additional growth factors/cytokines,short-term GSK inhibitor (GSKi) treatment effectively drives differentiation of hESCs into the primitive streak (PS),which can potentially commit toward the mesoderm when further supplemented with bone morphogenetic protein 4. Further analysis confirmed that the PS-like cells derived from GSKi treatment are bipotential,being able to specify toward the endoderm as well. Our findings suggest that the bipotential,PS/mesendoderm-like cell population exists only at the initial stages of GSK-3 inhibition,whereas long-term inhibition results in an endodermal fate. Lastly,we demonstrated that our differentiation approach could efficiently generate lateral plate (CD34(+)KDR(+)) and paraxial (CD34(-)PDGFRα(+)) mesoderm subsets that can be further differentiated along the endothelial and smooth muscle lineages,respectively. In conclusion,our study presents a unique approach for generating early mesoderm progenitors in a chemically directed fashion through the use of small-molecule GSK-3 inhibitor,which may be useful for future applications in regenerative medicine.

Induced pluripotent stem cells from patients with human fibrodysplasia ossificans progressiva show increased mineralization and cartilage formation.

BACKGROUND: Abnormal activation of endochondral bone formation in soft tissues causes significant medical diseases associated with disability and pain. Hyperactive mutations in the bone morphogenetic protein (BMP) type 1 receptor ACVR1 lead to fibrodysplasia ossificans progressiva (FOP),a rare genetic disorder characterized by progressive ossification in soft tissues. However,the specific cellular mechanisms are unclear. In addition,the difficulty obtaining tissue samples from FOP patients and the limitations in mouse models of FOP hamper our ability to dissect the pathogenesis of FOP.backslashnbackslashnMETHODS: To address these challenges and develop a disease model in a dish"� View Publication

Monitoring the biology stability of human umbilical cord-derived mesenchymal stem cells during long-term culture in serum-free medium.

Mesenchymal stem cells (MSCs) are multipotent adult stem cells that have an immunosuppressive effect. The biological stability of MSCs in serum-free medium during long-term culture in vitro has not been elucidated clearly. The morphology,immunophenotype and multi-lineage potential were analyzed at passages 3,5,10,15,20,and 25 (P3,P5,P10,P15,P20,and P25,respectively). The cell cycle distribution,apoptosis,and karyotype of human umbilical cord-derived (hUC)-MSCs were analyzed at P3,P5,P10,P15,P20,and P25. From P3 to P25,the three defining biological properties of hUC-MSCs [adherence to plastic,specific surface antigen expression,multipotent differentiation potential] met the standards proposed by the International Society for Cellular Therapy for definition of MSCs. The cell cycle distribution analysis at the P25 showed that the percentage of cells at G0/G1 was increased,compared with the cells at P3 (P textless 0.05). Cells at P25 displayed an increase in the apoptosis rate (to 183 %),compared to those at P3 (P textless 0.01). Within subculture generations 3-20 (P3-P20),the differences between the cell apoptotic rates were not statistically significant (P textgreater 0.05). There were no detectable chromosome eliminations,displacements,or chromosomal imbalances,as assessed by the karyotyping guidelines of the International System for Human Cytogenetic Nomenclature (ISCN,2009). Long-term culture affects the biological stability of MSCs in serum-free MesenCult-XF medium. MSCs can be expanded up to the 25th passage without chromosomal changes by G-band. The best biological activity period and stability appeared between the third to 20th generations. View Publication

Enhanced Non-Viral Gene Delivery to Human Embryonic Stem Cells via Small Molecule-Mediated Transient Alteration of Cell Structure.

Non-viral gene delivery into human embryonic stem cells (hESCs)is an important tool for controlling cell fate. However,the delivery efficiency remains low due in part to the tight colony structure of the cells which prevents effective exposure towards delivery vectors. We herein report a novel approach to enhance non-viral gene delivery to hESCs by transiently altering the cell and colony structure. (R)-(+)-trans-4-(1-aminoethyl)-N-(4-pyridyl)cyclohexanecarboxamide (Y-27632),a small molecule that inhibits the rho-associated protein kinase pathway,is utilized to induce transient colony spreading which leads to increased transfection efficiency by 1.5 to 2 folds in a spectrum of non-viral transfection reagents including Lipofectamine 2000 and Fugene HD. After removal of Y-27632 post-transfection,cells can revert back to its normal state and do not show alteration of pluripotency. This approach provides a simple,effective tool to enhance non-viral gene delivery into adherent hESCs for genetic manipulation. View Publication
