SCIENCE NEWS

Largest Gene Study of Childhood IBD Finds 5 New Genes
In the largest, most comprehensive genetic analysis of childhood-onset inflammatory bowel disease (IBD), an international research team has identified five new gene regions, one of which contains the IL27 gene that carries the code for a cytokine called IL27 and acts on the T-helper 17 pathway. [The Children's Hospital of Philadelphia, Philadelphia]

Scientists Guide Immune Cells with Light and Microparticles
Scientists have developed a way to create artificial chemical trails that can be shaped in three dimensions over time. By controlling the chemical trails, the team was able to control the movements of neutrophils and study how they are able to respond to these signals. [Yale University, New Haven]

CURRENT PUBLICATIONS

A Dominant, Coordinated T Regulatory Cell-IgA Response to the Intestinal Microbiota
Intestinal IgA, but not serum IgA, was found to block mucosal flagellin uptake and systemic T cell activation in mice. [PNAS]

Th22 Cells Represent a Distinct Human T Cell Subset Involved in Epidermal Immunity and Remodeling
The human Th22 subset may represent a separate T cell subset with a distinct identity with respect to gene expression and function, present within the epidermal layer in inflammatory skin diseases. [J Clin Invest]

Apoptotic Dendritic Cells Induce Tolerance in Mice through Suppression of Dendritic Cell Maturation and Induction of Antigen-Specific Regulatory T Cells
In vitro culture of apoptotic Dendritic cells (DCs) with immature DCs, results in their uptake by immature DCs, which subsequently turn into tolerogenic DCs, which then secrete TGF-Beta1 and induce Foxp3+ regulatory T cells (Tregs). [J Immunol]

CD39+Foxp3+ Regulatory T Cells Suppress Pathogenic Th17 Cells and Are Impaired in Multiple Sclerosis
CD4+CD25+Foxp3+CD39+ Treg cells play an important role in constraining pathogenic Th17 cells and their reduction in multiple sclerosis patients might lead to an inability to control IL-17 mediated autoimmune inflammation. [J Immunol]

Ectopic T-bet Expression Licenses Dendritic Cells for IL-12-Independent Priming of Type 1 T Cells In Vitro
T-bet (TBX21) is a transcription factor required for the optimal development of type 1 immune responses. Researchers investigated whether human dendritic cells genetically engineered to express high levels of T-bet promote superior type 1 T cell responses in vitro. [J Immunol]

Th1, Th17, and Th9 Effector Cells Induce Experimental Autoimmune Encephalomyelitis with Different Pathological Phenotypes
Different effector T cell subsets with specificity for myelin Ags can induce CNS autoimmunity and that the pathological heterogeneity in multiple sclerosis lesions might in part be due to multiple distinct myelin-reactive effector T cells. [J Immunol]
