Norepinephrine May Shift the IL-12/IL-23 Ratio of Dendritic Cells towards IL-23 Predominance thus Favoring Th17 Differentiation

Norepinephrine May Shift the IL-12/IL-23 Ratio of Dendritic Cells towards IL-23 Predominance thus Favoring Th17 Differentiation

A new study published in the January 15, 2016 issue of the Journal of Immunology indicates that in murine bone marrow–derived dendritic cells (DCs), norepinephrine, via stimulation of β2-adrenoceptors, is able to promote a shift in the IL-12p70/IL-23 cytokine ratio. Primary and secondary lymphoid organs receive a rich autonomic nervous system innervation, mainly by the […]

Blocking IL-12 and IL-23 in APPPS1 Mouse Model Shows Promise as an Experimental Therapeutic Approach to Alzheimer’s Disease

Blocking IL-12 and IL-23 in APPPS1 Mouse Model Shows Promise as an Experimental Therapeutic Approach to Alzheimer’s Disease

A recent study, published in Nature Medicine is perhaps the first one to show interleukin (IL)-23 involvement, and implicates both IL-23 and IL-12, key pro-inflammatory cytokines in the pathogenesis of Alzheimer’s disease. Importantly, it also demonstrates that in the APPPS1 Alzheimer’s disease mouse model, preventing the effects of these mediators, or ‘immune hormones’, with antibodies […]

New Subset of T Helper Cells May Play a Critical Role in Multiple Sclerosis

New Subset of T Helper Cells May Play a Critical Role in Multiple Sclerosis

A study by Wanqiang Sheng and colleagues from the National University of Singapore, published in Cell Research identifies a new subset of T helper (Th) cells that may play a key role in autoimmune neuroinflammatory conditions such as multiple sclerosis. Recent evidence indicates that granulocyte-macrophage colony-stimulating factor (GM-CSF) is a major encephalitogenic factor contributing to […]

Important New Features and Glucocorticoid-Resistance of Pro-Inflammatory Th17 Cells

Important New Features and Glucocorticoid-Resistance of Pro-Inflammatory Th17 Cells

A recent study by Radha Ramesh and colleagues, published in the Journal of Experimental Medicine indicates that the expression of the multi-drug transporter MDR1 (also known as P-glycoprotein [P-gp] and ABCB1) is a marker that defines the pro-inflammatory nature of T helper (Th)17 cells. The Th17 cells are major players in inflammatory/autoimmune conditions, but not […]

IL-17: A Promising Therapeutic Target in Several Chronic Inflammatory Diseases

Commentary on the study by Dominique L. P. Baete and Vijay K. Kuchroo Nat Med. 2013 Jul;19(7):824-5 How Cytokine networks fuel inflammation: Interleukin-17 and a tale of two autoimmune diseases Since the discovery of T helper 17 (Th17) cells, an increasing body of evidence indicates that these cells play a major role in the development […]

A Hierarchical Cytokines Framework Defining Groups of Chronic Inflammatory Diseases: Learning From Cytokine-Targeted Therapies

Commentary on the study by George Schett et al, Nat Med, 2013 Jul;19(7):822-4 How cytokine networks fuel inflammation: Toward a cytokine-based disease taxonomy Extensive genome-wide association and epidemiological studies have shed light on the causes of chronic inflammatory diseases and have confirmed a central role of the immune system and particularly of cytokines [1]. Secreted […]

Microbial Deprivation, Inflammation and the Th17/IL-23 Axis in Cancer Development

Microbial Deprivation, Inflammation and the Th17/IL-23 Axis in Cancer Development

In a recent review article in Cancer and Metastasis Reviews Leena von Hertzen, H. Joensuu and T. Haahtela, from the Skin and Allergy Hospital, Helsinki University Central Hospital, Finland, summarize the epidemiological data related to microbe-rich environments and cancer, and discuss the involvement of the T helper (Th)17/Interleukin(IL)-23 axis and the immunomodulatory potential of environmental microbiota […]

Priming of Murine Bone Marrow-Derived Dendritic Cells with Epinephrine Favors the Induction of a Dominant Th2/Th17 Phenotype

Priming of Murine Bone Marrow-Derived Dendritic Cells with Epinephrine Favors the Induction of a Dominant Th2/Th17 Phenotype

A new study published in the journal Brain, Behavior, and Immunity indicates that the stress hormone epinephrine (also known as adrenaline) is able to drive a Th2/Th17-shift in dendritic cells (DCs) in the presence of a pathogenic stimulus. Dendritic cells cytokine and chemokine profiles are able to shape CD4+ T cell pathways and phenotypes and […]
