TOP STORY

SIV-Resistant Monkeys Close the Gates to Viral Infection
Researchers have identified a way some of sooty mangabeys’ immune cells resist infection: they close the gates that SIV and HIV use to get into the cell. [Press release from Emory University discussing online prepublication in Nature Medicine]

SCIENCE NEWS

Massachusetts General Hospital, Iacocca Foundation Announce Promising Results of Phase I Diabetes Trial
Promising results of a Phase I clinical trial of the generic drug BCG to treat advanced type I diabetes were announced. [Press release from Massachusetts General Hospital discussing research presented at the American Diabetes Association Scientific Sessions]

Gene Therapy Stimulates Protein that Blocks Immune Attack and Prevents Type 1 Diabetes in Mice
Increasing a specific protein in areas of the pancreas that produce insulin blocks the immune attack that causes type 1 diabetes, researchers reported. [Press release from the Child & Family Research Institute discussing online prepublication in the Journal of Clinical Investigation]

Results Released for Two Drug Studies Designed to Slow Progression of Type 1 Diabetes
The results of two diabetes drug studies, including one that shows promise for stopping the immune system’s attack on insulin-producing cells in people newly diagnosed with type I diabetes, were presented. [Press release from the University of Miami Miller School of Medicine discussing online prepublications in The Lancet]

Inovio Pharmaceuticals’ Prostate Cancer DNA Vaccine Demonstrates Strong T Cell Responses in Monkeys; Company on Track for Phase I Clinical Trial
Inovio Pharmaceuticals, Inc. announced that its therapeutic DNA vaccine for prostate cancer showed remarkable immune responses in monkeys, following similarly strong, antigen-specific and sustainable T cell levels in previously reported data from earlier animal studies. [Press release from Inovio Pharmaceuticals, Inc. discussing research presented at the BIO International Convention]

Avila Therapeutics Presents Preclinical Data with AVL-292, its Btk Inhibitor, Demonstrating Suppression of Autoimmune Disease Activity
Avila Therapeutics, Inc. announced the presentation of data on AVL-292, a clinical-stage inhibitor of Bruton’s tyrosine kinase (Btk). [Press release from Avila Therpeutics, Inc. discussing research presented at the 2011 Federation of Clinical Immunology Societies]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Antigen-Based Therapy with Glutamic Acid Decarboxylase (GAD) Vaccine in Patients with Recent-Onset Type 1 Diabetes: A Randomized Double-Blind Trial
Researchers aimed to assess whether immunization with GAD formulated with aluminum hydroxide would preserve insulin production in recent-onset type 1 diabetes. [Lancet]

Co-Stimulation Modulation with Abatacept in Patients with Recent-Onset Type 1 Diabetes: A Randomized, Double-Blind, Placebo-Controlled Trial
In this multicentre, double-blind, randomized controlled trial, patients aged 6—45 years recently diagnosed with type 1 diabetes were randomly assigned (2:1) to receive abatacept (10 mg/kg, maximum 1000 mg per dose) or placebo infusions intravenously on days 1, 14, 28, and monthly for a total of 27 infusions over 2 years. [Lancet]

Low Levels of SIV Infection in Sooty Mangabey Central Memory CD4+ T Cells Are Associated with Limited CCR5 Expression
Here researchers found that, after in vitro stimulation, sooty mangabey CD4+ T cells fail to upregulate CCR5 and that this phenomenon is more pronounced in CD4+ central memory T cells. [Nat Med]

Signaling by the Phosphatase MKP-1 in Dendritic Cells Imprints Distinct Effector and Regulatory T Cell Fates
Here researchers report that dendritic cell (DC)-expressed phosphatase MKP-1, a negative regulator of the MAP kinases, programmed reciprocal T helper 1 (Th1) and Th17 cell differentiation by modulating IL-12-STAT4 and IL-6-STAT3 axes and cytokine receptor expression at the DC-T cell interface. [Immunity]

Prevention of Murine Autoimmune Diabetes by CCL22-Mediated Treg Recruitment to the Pancreatic Islets
Here, researchers demonstrate that production of CCL22 in islets after intrapancreatic duct injection of double-stranded adeno-associated virus encoding CCL22 recruits endogenous regulatory T cells (Tregs) to the islets and confers long-term protection from autoimmune diabetes in NOD mice. [J Clin Invest]

Foxp3+ Regulatory T Cells Exert Asymmetric Control Over Murine Helper Responses by Inducing Th2 Cell Apoptosis
Researchers found that in vivo Foxp3+ regulatory T cell frequency had a proportionate relationship with generalized T cell activation and Th1 magnitude, but had a surprising disproportionate relationship with Th2 magnitude. [Blood]

CD31 Is Required on CD4+ T Cells to Promote T Cell Survival During Salmonella Infection
Using adoptive transfer experiments, researchers show that loss of CD31 on CD4+ T cells alone is sufficient to account for the defective CD31-deficient T cell accumulation. [J Immunol]

TNF Receptor 1 Deficiency Increases Regulatory T Cell Function in Nonobese Diabetic Mice
This study suggests that blocking TNF signaling may be beneficial in increasing the function of T regulatory cells and suppression of type 1 diabetes. [J Immunol]

Adoptive Transfer of DCs Isolated from Helminth-Infected Mice Enhanced T Regulatory Cell Responses in Airway Allergic Inflammation
In the present study, researchers examined the mechanism by which dendritic cells (DCs) contribute to inhibition of allergy. [Parasite Immunol]
