Transcriptome-Based Network Analysis Reveals a Spectrum Model of Human Macrophage Activation
The authors stimulated human macrophages with diverse activation signals, acquiring a data set of 299 macrophage transcriptomes. Analysis of this data set revealed a spectrum of macrophage activation states extending the current M1 versus M2-polarization model. [Immunity]

T Cell Repertoire following Autologous Stem Cell Transplantation for Multiple Sclerosis
In a Phase II study of hematopoietic stem cell transplantation (HSCT) for poor-prognosis multiple sclerosis, scientists used high-throughput deep TCRß chain sequencing to assess millions of individual TCRs per patient sample. They found that HSCT has distinctive effects on CD4+ and CD8+ T cell repertoires. [J Clin Invest]

Regulatory T Cells in Rheumatoid Arthritis Showed Increased Plasticity toward Th17 but Retained Suppressive Function in Peripheral Blood
Scientists investigated IL-17-producing regulatory T cells from patients with rheumatoid arthritis, and characterized their regulatory capacity and clinical significance. [Ann Rheum Dis] Abstract

Hypoxia and STAT3 Signaling Interactions Regulate Pro-Inflammatory Pathways in Rheumatoid Arthritis
Researchers examined the effect of hypoxia on Signal Transducer and Activator of Transcription 3 (STAT3)-induced pro-inflammatory pathways in rheumatoid arthritis. [Ann Rheum Dis] Abstract

Differential Effects of Fingolimod on B-Cell Populations in Multiple Sclerosis
Scientists analyzed blood samples from nine fingolimod-treated and 19 control patients with multiple sclerosis by flow cytometry, to determine the frequencies and activation states of naive B cells, memory B cells, and plasmablasts. The frequencies of each B-cell population in peripheral blood mononuclear cells were greatly reduced two weeks after starting fingolimod treatment. [Mult Scler] Abstract

TIRC7 and HLA-DR Axis Contributes to Inflammation in Multiple Sclerosis
TIRC7 was expressed in brain-infiltrating lymphocytes and strongly correlated with disease activity in multiple sclerosis (MS). TIRC7 expression was reduced in T cells and induced in B cells in peripheral blood lymphocytes obtained from MS patients. [Mult Scler] Abstract

ImmTAC-Redirected Tumor Cell Killing Induces and Potentiates Antigen Cross-Presentation by Dendritic Cells
Using an ImmTAC (immune-mobilizing monoclonal T cell receptor against cancer) specific for a HLA-A*02-restricted peptide derived from the melanoma antigen gp100, scientists observed that ImmTAC-driven melanoma-cell death leads to cross-presentation of melanoma antigens by dendritic cells. [Cancer Immunol Immunother] Abstract

Bufalin, a Bioactive Component of the Chinese Medicine Chansu, Inhibits Inflammation and Invasion of Human Rheumatoid Arthritis Fibroblast-Like Synoviocytes
Researchers investigated the effects of bufalin on tumor necrosis factor-alpha (TNF-a)-induced invasion of rheumatoid arthritis fibroblast-like synoviocytes. Their results revealed that TNF-a significantly increased p65 translocation into nucleus and enhanced nuclear factor-kappa B DNA-binding activity, which were dose-dependently inhibited by bufalin. [Inflammation] Abstract

Increased TTS Expression in Patients with Rheumatoid Arthritis
Scientists studied the imbalance expressions of indoleamine 2,3-dioxygenase (IDO) and tryptophanyl-tRNA synthetase (TTS) with rheumatoid arthritis patients. The expressions of IDO and TTS were analyzed by real-time quantitative polymerase chain reaction and flow cytometry in peripheral blood mononuclear cells. [Clin Exp Med] Abstract
