We expanded flow-sorted Foxp3(+) cynomolgus monkey regulatory T cells (Treg) >1000-fold after three rounds of stimulation with anti-CD3 mAb-loaded artificial antigen-presenting cells, rapamycin (first round only) and IL-2. The expanded Treg maintained their expression of Treg signature markers, CD25, CD27

Human exposure to high-linear energy transfer α-particles includes environmental (e.g. radon gas and its decay progeny), medical (e.g. radiopharmaceuticals) and occupational (nuclear industry) sources. The associated health risks of α-particle exposure for lung cancer are well documented however the risk

Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting biungulate species. Commercial vaccines, formulated with inactivated FMD virus (FMDV), are regularly used worldwide to control the disease. Here, we studied the generation of antibody responses in local lymphoid tissues

The Journal of pharmacology and experimental therapeutics, 351(3), 538-548 (2014-09-26)
The heterogeneity and severity of certain autoimmune diseases and B-cell malignancies warrant simultaneous targeting of multiple disease-relevant signaling pathways. Dual inhibition of spleen tyrosine kinase (SYK) and Janus kinase (JAK) represents such a strategy and may elicit several benefits relative

Journal of immunology (Baltimore, Md. : 1950), 193(5), 2587-2599 (2014-07-30)
Adoptive immunotherapy with Ag-specific T lymphocytes is a powerful strategy for cancer treatment. However, most tumor Ags are nonreactive "self" proteins, which presents an immunotherapy design challenge. Recent studies have shown that tumor-specific TCRs can be transduced into normal PBLs

EGFR/HER2 are frequently expressed in MPM tissues, however, no studies have shown the clinical benefit of using EGFR/HER2-targeting drugs in patients with malignant pleural mesothelioma (MPM). It was reported that the tyrosine kinase inhibitor (TKI) lapatinib enhanced trastuzumab-mediated antibody-dependent cellular

We previously reported that IL-2 deprivation induced acid sphingomyelinase-mediated (ASM-mediated) ceramide elevation and apoptosis in an NK/T lymphoma cell line KHYG-1. However, the molecular mechanism of ASM-ceramide-mediated apoptosis during IL-2 deprivation is poorly understood. Here, we showed that IL-2 deprivation

Imbalance between effector and regulatory T-cells (Treg) underlies the loss of immune-tolerance to self-antigens in autoimmune disease. In autoimmune hepatitis type 2 (AIH-2), effector CD4 T-cell immune responses to cytochrome P450IID6 (CYP2D6) are permitted by numerically and functionally impaired Treg.

The development of novel strategies to prevent HIV-1 infection is of outstanding relevance. Metal complexes of Cu(2+), Ni(2+), Co(2+) and Zn(2+) derived from sulfonated and carboxylated poly(propylene imine) dendrimers with ethylenediamine core were evaluated as tunable antiviral agents against HIV-1.

The costimulatory molecules B7-H3 and B7-H4 are overexpressed in a variety of human tumors and have been hypothesized as possible biomarkers and immunotherapeutic targets. Despite this potential, the predominating uncertainty about their functional implication in tumor-host interaction hampers their evaluation

Human multipotent adult progenitor cells (hMAPCs) are isolated from bone marrow with a more extensive expansion capacity compared to human mesenchymal stem cells (hMSCs) and with the ability to differentiate into endothelium. Like hMSCs, hMAPCs inhibit T-cell proliferation induced by
