TOP STORY
Researchers Report Long-Term Remissions in First Group of Patients to Receive Personalized Cellular Therapy for Chronic Lymphocytic Leukemia
Eight of 14 patients in the first trial of the University of Pennsylvania’s personalized cellular therapy for chronic lymphocytic leukemia responded to the therapy, with some complete remissions continuing past four and a half years. [Press release from the University of Pennsylvania discussing online publication in Science Translational Medicine] Press Release | Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
Low-Dose Interleukin-2 Selectively Corrects Regulatory T Cell Defects in Patients with Systemic Lupus Erythematosus
Peripheral blood mononuclear cells (PBMC) from 61 patients with systemic lupus erythematosus and 52 healthy donors and in vitro IL-2 stimulated PBMC were characterized by multicolor flow cytometry. [Ann Rheum Dis] Abstract

Double-Negative αβ T Cells Are Early Responders to AKI and Are Found in Human Kidney
Researchers phenotypically and functionally characterized murine kidney CD4CD8 (double-negative; DN) T cells in the steady state and in response to ischemia-reperfusion injury. DN T cells also made up a large fraction of the T cell compartment in human kidneys. [J Am Soc Nephrol] Abstract

IL-11 Induces Differentiation of Myeloid-Derived Suppressor Cells through Activation of STAT3 Signaling Pathway
Scientists found that CD11b+CD14+ monocytic myeloid-derived suppressor cells were generated from peripheral blood mononuclear cells (PBMCs) of healthy donors in the presence of interleukin (IL)-11. IL-11-conditioned PBMCs induced higher expression of immunosuppressive molecules such as arginase-1. [Sci Rep] Full Article

Characteristics of Tumor Infiltrating Lymphocyte and Circulating Lymphocyte Repertoires in Pancreatic Cancer by the Sequencing of T Cell Receptors
T cells from primary tumor and blood of sixteen patients with pancreatic cancer were characterized by deep sequencing. By analyzing the complementary determining region 3 gene sequence, investigators found no significant differences in the T cell receptor repertoires between patients and healthy controls. [Sci Rep] Full Article

Low Marginal Zone-Like B Lymphocytes and Natural Antibodies Characterize Skewed B-Lymphocyte Subpopulations in del22q11 diGeorge Patients
The authors characterized the B-cell compartment in diGeorge syndrome patients. They observed a significantly increased number of naive B-cells and decreased number of switched memory B-cells in diGeorge patients. [Clin Immunol] Abstract

Effects of Aging on Human Leukocytes (Part II): Immunophenotyping of Adaptive Immune B and T Cell Subsets
Scientists investigated alterations in the subpopulations of the B and T cells among 24 healthy young and 26 healthy elderly individuals. γδTCR+ T cells were overall decreased, while CD4+CD8 cells among γδTCR+ T cells were increased in the elderly. [Age] Abstract

Vaccination Expands Antigen-Specific CD4+ Memory T Cells and Mobilizes Bystander Central Memory T Cells
The authors showed in healthy volunteers that a booster vaccination with tetanus toxoid (TT) expanded peripheral blood TT-specific CD4+ T helper memory (Thmem) cells as expected, but was accompanied by parallel increase of Thmem cells specific for two unrelated and non cross-reactive common recall antigens. In a new cohort of healthy human subjects, they compared blood vaccine-specific and bystander Thmem cells in terms of differentiation stage, function, activation and proliferative status.

Low HIP1R mRNA and Protein Expression Are Associated with Worse Survival in Diffuse Large B-Cell Lymphoma Patients Treated with R-CHOP
Researchers have previously shown that low HIP1R protein expression was associated with poorer survival in diffuse large B-cell lymphoma patients from Denmark treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). They extended these findings and validated the prognostic and subtyping utility of HIP1R expression at both transcript and protein level. [Exp Mol Pathol] Abstract

REVIEWS
BTK Signaling in B Cell Differentiation and Autoimmunity
The authors focus on the role of Bruton’s tyrosine kinase (BTK) during B cell differentiation in vivo, both in the regulation of expansion and in the developmental progression of pre-B cells in the bone marrow and as a crucial signal transducer of signals downstream of the IgM or IgG B cell antigen receptor in mature B cells governing proliferation, survival, and differentiation.
