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 […]

Experimental Study Shows Link between Cerebrospinal Fluid IL-6 and Depressive Symptoms in Humans

Experimental Study Shows Link between Cerebrospinal Fluid IL-6 and Depressive Symptoms in Humans

A recent study published in Molecular Psychiatry suggests that the appearance of depressive symptoms in inflammatory conditions might be primarily linked to an increase in central IL-6 concentration. Inflammation is a physiological response to infection and tissue injury that involves the release of pro-inflammatory (e.g., TNF-α, IL-6) and anti-inflammatory (e.g., IL-10) cytokines from activated immune […]

Generalized Anxiety Disorder Linked to High IFN-γ and TNF-α but Low IL-10 Peripheral Levels

Generalized Anxiety Disorder Linked to High IFN-γ and TNF-α but Low IL-10 Peripheral Levels

A recent Brain, Behavior, and Immunity study provides perhaps the first evidence that Generalized Anxiety Disorder (GAD) is associated with a peripheral imbalance of pro- versus anti- inflammatory cytokines such as interferon (IFN)-γ, tumor necrosis factor (TNF)-α and interleukin (IL)-10. GAD, classified since the 1980s in the Diagnostic and Statistical Manual of Mental Disorder is […]

Stress and Catecholamines Up-Regulate Proinflammatory Cytokine Production and Neutrophil Infiltration in Experimental Colitis

Stress and Catecholamines Up-Regulate Proinflammatory Cytokine Production and Neutrophil Infiltration in Experimental Colitis

A recent Brain, Behavior and Immunity study indicates that psychological stress contributes to the exacerbation of the murine model of colitis by promoting the mobilization and entry of neutrophils in the colon. This appears to be achieved by the up-regulation of pro-inflammatory cytokine and chemokine production and STAT3 signaling, and involves β1/β2-adrenergic receptors activation. Inflammatory […]

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 […]

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 […]

Chronic Stress Induces Shrinkage of Medial Amygdala Neurons in Mice: Recovery by the Fast-Acting Candidate Antidepressant Acetyl-L-Carnitine

Chronic Stress Induces Shrinkage of Medial Amygdala Neurons in Mice: Recovery by the Fast-Acting Candidate Antidepressant Acetyl-L-Carnitine

A recent study in Molecular Psychiatry provides new evidence that chronic stress generates structural remodelling of the brain amygdala, and particularly the shrinkage of medial amygdala neurons in mice. Chronic stress has been linked to cognitive impairment, but it is also known that stress modifies the neuronal architecture in several brain cognitive areas. However, little […]

Deficiency of Stress Resilience in Late Adolescence Linked To Increased Risk of Hypertension in Adulthood

Deficiency of Stress Resilience in Late Adolescence Linked To Increased Risk of Hypertension in Adulthood

A new study published in the journal Heart indicates that men with low stress resilience during youth are prone to approximately 40% increase in the risk of developing hypertension in later life. Of note, the combination of low stress resilience and high body mass index (BMI) triples the hypertension risk. High blood pressure is a […]

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 […]

More Evidence that Norepinephrine and β3-Adrenoreceptors May Drive Melanoma Progression & Aggressiveness

More Evidence that Norepinephrine and β3-Adrenoreceptors May Drive Melanoma Progression & Aggressiveness

A report recently published in Oncotarget shows that the β3-adrenoreceptors are involved in melanoma aggressiveness, and that these receptors, expressed on several accessory cells, may orchestrate their function and thus, sustain melanoma progression. Recent research indicates that stress and stress mediators contribute to cancer development and/or progression. It appears that in this process a major […]
