Although cigarette smoke is known to alter immune responses, whether and how CD4 T cells are affected is not well-described. We aimed to characterize how exposure to cigarette smoke extract impacts CD4 T cell effector generation in vitro under Th1-polarizing conditions. Our results demonstrate that cigarette smoke directly acts on CD4 T cells to impair effector expansion by decreasing division and increasing apoptosis. Read More

Regulatory T cells (Tregs) suppress the activity of effector T, B and NK lymphocytes and sustain immunological tolerance, but the proliferative activity of suppressed cells remains unexplored. In the present study, we report that mouse Tregs can induce replicative senescence and the death of responder mouse CD4CD25 T cells, CD8 T cells, B cells and NK cells in vitro and in vivo. Contact-independent in vitro co-cultivation with Tregs up-regulated endonuclease G (EndoG) expression and its translocation to the nucleus in responder cells. Read More

Identifying targets for chimeric antigen receptor-modulated T lymphocyte (CAR-T) therapy against solid tumors is an urgent problem to solve. In this study, we showed for the first time that the receptor tyrosine kinase, AXL, is overexpressed in various tumor cell lines and patient tumor tissues including triple negative breast cancer (TNBC) cell lines and patient samples, making AXL a potent novel target for cancer therapy, specifically for TNBC treatment. We also engineered T cells with a CAR consisting of a novel single-chain variable fragment against AXL and revealed its antigen-specific cytotoxicity and ability to release cytokines in a TNBC cell line and other AXL-positive tumors in vitro.

IL-13 receptor alpha 1 (IL-13Rα1) associates with IL-4Rα to form a functional IL-4Rα/IL-13Rα1 heteroreceptor (HR) through which both IL-4 and IL-13 signal. Recently, HR expression was associated with the development of M2 type macrophages which function as antigen presenting cells (APCs). Herein, we show that a subset of thymic resident dendritic cells (DCs) expressing high CD11b (CD11b) and intermediate CD11c (CD11c) arise in HR-sufficient but not HR-deficient mice. Read More

Dendritic cells (DCs) contain heterogeneous populations, with classical DCs developed at steady state and monocyte-derived DCs mobilized under inflammatory conditions, although their total numbers in vivo are scares. To obtain enough quantity for immunological study or clinical application, we have previously established that bone marrow-derived DCs in the presence of Flt-3L (FL-DCs) or GM-CSF (GM-DCs) in vitro are equivalent to the steady state DCs and inflammatory DCs in vivo respectively. What difference, however, exists between these two most commonly used culture systems in DC functions and survival, and how does it correlate to the division of works by their corresponding counterparts in vivo remain ill-defined.

O-linked β-N-acetyl glucosamine modification (O-GlcNAcylation) is a dynamic, reversible posttranslational modification of cytoplasmic and nuclear proteins. O-GlcNAcylation depends on nutrient availability and the hexosamine biosynthetic pathway (HBP), which produces the donor substrate UDP-GlcNAc. O-GlcNAcylation is mediated by a single enzyme, O-GlcNAc transferase (OGT), which adds GlcNAc and another enzyme, O-GlcNAcase (OGA), which removes O-GlcNAc from proteins. Read More

Methods: We analyzed, whether the addition of PINDs during DC cultures (15 healthy, 22 leukemic donors) and mixed lymphocyte culture (MLC, n = 15) with autologous (n = 6), allogeneic (n = 2) or T-cells after stem cell transplantation (SCT; n = 7) would alter the quality and quantity of DC, the composition of T-cell-subsets, and/or their antileukemic functionality (AF) as studied by FACS and functional Fluorolysis-cytotoxicity-assays.

Tumour metastasis is the main cause of cancer related deaths. Metastasis is an intricate multi-step process that requires the acquisition of several cancer cell features, including the modulation of tumour cell migration, adhesion, invasion, and immune evasion. Changes in the cellular glycosylation are associated with malignant transformation of cancer cells, tumour progression and ultimately, metastasis formation. Read More

Immune tolerance is a vital component of immunity, as persistent activation of immune cells causes significant tissue damage and loss of tolerance leads to autoimmunity. Likewise, unwanted immune responses can occur in inherited disorders, such as hemophilia and Pompe disease, in which patients lack any expression of protein, during treatment with enzyme replacement therapy, or gene therapy. While the liver has long been known as being tolerogenic, it was only recently appreciated in the last decade that liver directed adeno-associated virus (AAV) gene therapy can induce systemic tolerance to a transgene.

This study was conducted to investigate the use of Alpha 1-antitrypsin (AAT) to inhibit microglia activation in chronic hypertension model and provide a permissive environment for stem cell transplantation. Chronic ocular hypertension of C57BL/6 mice using magnetic microbead injection was induced 3 weeks prior to iPSCs transplantation. The ocular hypertension model was assessed histologically and intraocular pressure was measured. Read More

Adeno-associated virus (AAV) vectors are promising candidates for gene therapy and have been explored as gene delivery vehicles in the treatment of Duchenne Muscular Dystrophy (DMD). Recent studies showed compelling evidence of therapeutic efficacy in large animal models following the intravenous delivery of AAV vectors expressing truncated forms of dystrophin. However, to translate these results to humans, careful assessment of the prevalence of anti-AAV neutralizing antibodies (NAbs) is needed, as presence of preexisting NABs to AAV in serum have been associated with a drastic diminution of vector transduction.

Myeloid-derived suppressor cells (MDSCs) are found frequently in patients and mice bearing tumors, which derived from immature myeloid cells. In healthy individuals, immature myeloid cells formed in the bone marrow differentiating to dendritic cells, macrophages and neutrophils. However, it is unclear whether some gene deficiency will lead to MDSCs accumulation in mice without bearing tumor. Read More
