2017 in Review: New Advances in Neuroendocrine Immunology

2017 in Review: New Advances in Neuroendocrine Immunology

Editorial In 2017, we witnessed further rapid growth in the vast interdisciplinary area of neuroendocrine immunology. It became a tradition to reflect on the new significant developments and conceptual trends in the field that were presented at BrainImmune. We will retrace some of our commentaries, revisiting the studies on BrainImmune we believe are illustrative, stimulating […]

First Evidence that Catecholamines Inhibit IL-27 Production by Antigen Presenting Cells

First Evidence that Catecholamines Inhibit IL-27 Production by Antigen Presenting Cells

A recent J. Immunology study provides perhaps the first evidence that catecholamines such as norepinephrine and epinephrine suppress the production of interleukin-27 (IL-27) via the activation of β2-adrenoceptors, and by mechanisms involving IL-10 and the JNK signaling pathway. Homeostasis within the immune system is largely dependent on cytokines, the ‘hormones’ of the immune system that […]

First Evidence that Macrophages Modulate Heart Electrical Conduction System

First Evidence that Macrophages Modulate Heart Electrical Conduction System

In a recent Cell study, Maarten Hulsmans et al. report the presence of abundant resident macrophages in the heart atrioventricular (AV) node, and provide first evidence that these cells modulate the electrical conduction and activity of cardiomyocytes. This phenomenon may be related to the pathogenic electrical conduction in heart conditions such as atrial fibrillation and […]

A Sympathetic-Adrenal Neuroimmune Reflex Linked to the Immunosuppressive Effects of Spinal Cord Injury

A Sympathetic-Adrenal Neuroimmune Reflex Linked to the Immunosuppressive Effects of Spinal Cord Injury

A recent study published in Nature Neuroscience indicates that the increased susceptibility to life-threatening infections in spinal cord injury (SCI) patients may result from the disruption of the physiological interactions within a neuroendocrine reflex involving the sympathetic nervous system (SNS) and the adrenal glands. The control of the immune system by the peripheral autonomic nervous […]

Afferent Vagus Nerve Stimulation Activates Brain Locus Coeruleus and Improves Experimental Joint Inflammation

Afferent Vagus Nerve Stimulation Activates Brain Locus Coeruleus and Improves Experimental Joint Inflammation

A recent study published in the Brain, Behavior, and Immunity journal indicates, for the first time, that stimulation of vagal afferents or specific brain areas can modulate joint inflammation. This new central pathway involves sympathetic nervous system activation and local stimulation of synovial β-adrenoceptors. Vagus nerve stimulation (VNS) is a well-known procedure that limits inflammation and […]

The Central Inflammatory Reflex: Afferent Vagal and Central Brain Stimulations Control Experimental Arthritis

The Central Inflammatory Reflex: Afferent Vagal and Central Brain Stimulations Control Experimental Arthritis

PhD THESIS SYNOPSIS Inflammation is a protective and complex biological response to harmful stimuli, such as infection and tissue damage, that involves cell infiltration and production of inflammatory cytokines. Rheumatoid Arthritis (RA) is the most common type of inflammatory autoimmune disease affecting over 1.5 million adult Americans. It is characterized by chronic inflammation of synovial […]

Activation of the Brain-Splenic Nerve Axis in Hypertension: The Cholinergic-Sympathetic-Immune System Connection

Activation of the Brain-Splenic Nerve Axis in Hypertension: The Cholinergic-Sympathetic-Immune System Connection

A recent Nature Communications study indicates that hypertension is linked to T cell activation and an egression of T-cells from the spleen, and that this process is dependent on a vagus-splenic nerve connection. Hypertension is a major risk factor for coronary heart diseases and stroke. Despite various therapeutic approaches 10-15% of the general hypertensive population […]

Glucocorticoid-Resistant IL-17- and IL-22-secreting CD4+ T Cells May Contribute to Increased Disease Activity in Multiple Sclerosis

Glucocorticoid-Resistant IL-17- and IL-22-secreting CD4+ T Cells May Contribute to Increased Disease Activity in Multiple Sclerosis

A recent study published in Immunology is perhaps the first to demonstrate a correlation between the production of interleukin (IL)-17 and IL-22, and its glucocorticoid resistance, and the number of active brain lesions in multiple sclerosis (MS). Increased active brain lesions were found in patients whose IL-17- and IL-22-producing T cells were more resistant to […]

New Function of Microglia: Promotion of Filopodia and Hence Synaptogenesis during Early Brain Development

New Function of Microglia: Promotion of Filopodia and Hence Synaptogenesis during Early Brain Development

A recent study published in Nature Communications reveals that the brain microglia influences the developing brain through induction of filopodia creation, thus, shaping neuronal connectivity and synapses formation. Microglia are important components of the neuro-immune interactions in the brain. As the resident macrophage cells, the microglial cells provide the main immune defense in the central […]

First Evidence that Meningeal Interferon-γ Affects Neuronal Connectivity and Social Behavior

First Evidence that Meningeal Interferon-γ Affects Neuronal Connectivity and Social Behavior

A recent study published in Nature magazine links the meningeal immunity to the regulation of social behavior, implicating the meningeal interferon (IFN)-γ and its modulatory effects on the activity of brain cortex GABAergic neurons. Diseases such as autism spectrum disorder, frontotemporal dementia and schizophrenia are characterized by severe social and immune dysfunction. Little is known […]
