Limbic response to stress linking life trauma and hypothalamus-pituitary-adrenal axis function
Lifetime trauma exposure has been shown to significantly impact physical and psychological well-being, increasing risk for stress-related disorders and negative health outcomes (Bevans et al., 2008; McEwen, 2002; Sinha, 2008). Studies have identified the neurobiological underpinnings of trauma exposure; this line of studies has largely found altered function associated with trauma in two stress-related pathways, the hypothalamic –pituitary–adrenal (HPA) axis system (Fries et al., 2005) and limbic brain regions (McEwen, 2001; Williams et al., 2006).

Discrimination Exposure and DNA Methylation of Stress-Related Genes in Latina Mothers
The accumulation of stress over the lifespan can contribute to biological vulnerability and directly affect health outcomes for mothers and their children. Latina women, who have the highest fertility rate among all ethnic groups and represent the largest minority group in the US (Center, 2015), are exposed to a multitude of stressful events and sociocultural factors, including discrimination (Ay ón, 2015). Extant research in Latinas has largely focused on varied levels of exposure to risk and protective factors in the perinatal period including socio-determinants of health (e.g., socioeconomic background), prenatal...

Emerging role of the P2 × 7-NRLP3-IL1β pathway in mood disorders
It is now well established that mood disorders such as major depressive disorder (MDD) and bipolar disorder (BD) show high lifetime prevalence rates resulting in significant impact on quality of life to patients and their families (Hirschfeld, 2012). This is compounded by the negative social stigma associated with mental health, resulting in delayed medical assistance, causing debilitating neuropsychological conditions, sometimes leading to suicidal ideation and death. When patients with mood disorders do seek medical attention, a large proportion of the patient pool either do not respond adequately or with only a very lim...

Modulating Kynurenine Monooxygenase in Microglia: the need for further characterization
In their paper, Garrison et al. studied the effects of inhibiting kynurenine monooxygenase (KMO) on microglia activation. The authors observed attenuation of several pro-inflammatory cytokines and nitrite after genetic and pharmacological inhibition of KMO, and identified subsequent kynurenine (KYN) accumulation as the likely source of this effect. There are several concerns about the study that should be discussed. (Source: Psychoneuroendocrinology)

Sex Hormones and Incident Dementia in Older Men: The Health in Men Study
Dementia affects approximately 6.5% of adults over the age of 65 and its burden is projected to rise (Wu et al., 2017). As current treatments are mostly symptomatic, prevention is key to reducing the burden of dementia. It has been suggested that more than a third of dementia cases could be prevented by systematically addressing potentially modifiable risk factors from across the life-span (Livingston et al., 2017). One potentially modifiable factor not included in these analyses was testosterone status. (Source: Psychoneuroendocrinology)

Role of DHEA and Cortisol in Prefrontal-Amygdalar Development and Working Memory
Cortisol and dehydroepiandrosterone (DHEA) are the most abundant adrenal hormones of the hypothalamic-pituitary-adrenal (HPA) axis and exert potent, pleiotropic effects on human physiology including regulation of immune, metabolic and cognitive function (Kamin and Kertes 2017). The role of cortisol in supporting acute stress responses by drawing upon the brain and the body ’s energy reserves (i.e. increasing the body’s catabolic state) has been extensively investigated (Nicolaides et al., 2014). Notably, cortisol may lead to increased neurotoxicity (and other adverse physical effects) when it remains elevated f...

Stress burden and neuroendocrine regulation of cytokine production in patients with ulcerative colitis in remission
Ulcerative colitis (UC) is a chronic relapsing and remitting inflammatory bowel disease (IBD) affecting the mucosal layer of the large intestine. Disease flares are characterized by intestinal mucosal inflammation, bloody diarrhea, fecal urgency, and abdominal pain. Despite considerable progress in research, the aetiology of UC remains elusive and is thought to be multifactorial, involving genetic and environmental factors, immune dysregulation, and alterations in intestinal microflora (Ananthakrishnan, 2015).

Childhood maltreatment, pituitary volume and adolescent hypothalamic-pituitary-adrenal axis – evidence for a maltreatment-related attenuation
Child maltreatment is a widespread phenomenon affecting the lives of millions of children all over the world (Stoltenborgh et al., 2015). Preclinical and clinical studies suggest that experiences of childhood maltreatment lead to enduring changes in both the activity, and particularly the reactivity, of the hypothalamic-pituitary-adrenal axis (HPAA); however, data on the exact developmental pathways of these alterations are rare (McCrory et al., 2010; Tarullo and Gunnar, 2006). The HPAA is one of the major stress response systems of the human body (Gunnar and Quevedo, 2007); HPAA activation causes the release of corticotro...

Perinatal high fat diet induces early activation of endocrine stress responsivity and anxiety-like behavior in neonatal offspring
Worldwide, there has been a dramatic increase in obesity prevalence, including in women of reproductive age (Fisher et al., 2013). Maternal obesity predisposes offspring to metabolic and neuropsychological disorders later in life (Dearden and Ozanne, 2015; Rivera et al., 2015). The hypothalamic-pituitary-adrenal (HPA) axis, the mediator of the endocrine stress response, is sensitive to environmental factors early in life and HPA programming is associated with anxiety behaviors later in life (McGowan and Matthews, 2017).

The paper by Strandqvist and colleagues on cognitive abilities in women with disorders of development ( DSD) reports a striking finding: sex chromosomes determine emotion recognition. How did they arrive at such a dramatic conclusion? They studied women with complete androgen insensitivity syndrome ( CAIS) who are XY and women with gonadal dysgenesis ( GD) with either XX or XY chromosomes. None were exposed in utero to androgens, either because of resistance to their action (CAIS) or from lack of androgen production (GD).Thus the effect of androgens on, for example, spatial ability well recognised to be sex dimorphic is re...

Effects of acute olanzapine exposure on central insulin-mediated regulation of whole body fuel selection and feeding
The use of antipsychotics (APs) is increasing at an alarming rate, owing to expanding on- and off-label uses in adults and children (Pringsheim and Gardner, 2014). This is concerning due to the severe metabolic side effects associated with chronic and acute AP-use. In addition to the increased propensity for weight gain and related comorbidities (Bergman and Ader, 2005), acute AP-exposure is associated with rapid, unmatched fuel repartitioning (Klingerman et al., 2014). Specifically, treatment with the AP olanzapine has been shown to increase hepatic glucose output (Houseknecht et al., 2007) and decrease adipose tissue lip...

The prevalence of obesity has steadily risen worldwide in the last few decades and has become a major public health issue. More than one-third of adults (34.9%) in the United States are obese (Ogden et al., 2013). Obesity, particularly in the visceral region, is related to increased risk of diseases such as diabetes, cardiovascular disease (CVD), and some cancers (Tchernof and Despres, 2013). Measures such as body mass index (BMI) and weight give limited information about disease risk because they lack the ability to determine body fat distribution. (Source: Psychoneuroendocrinology)

Early life stress accelerates age-induced effects on neurogenesis, depression, and metabolic risk
Metabolic syndrome (MetS) is a cluster of risk factors that include obesity, insulin resistance, hyperlipidemia, and hypertension. MetS increases the risk for cardiovascular disease and type 2 diabetes (T2DM), and shows a high comorbidity with depression (Zanoveli et al., 2016). However, this relationship is complex and poorly understood. Clinical evidence has shown that while T2DM did not predict symptoms of depression or anxiety, these symptoms emerged as significant risk factors for the onset of T2DM.

Associations between adrenarcheal hormones, amygdala functional connectivity and anxiety symptoms in children
Anxiety disorders are common in childhood and adolescence (Costello et al., 2003). They have an early median age of onset compared to other forms of psychopathology, such as depression (Kessler et al., 2005), and often persist through adolescence (Costello et al., 2003). Further, elevated anxiety symptoms during childhood are associated with increased risk for later anxiety and depressive disorders (Keenan et al., 2009). The transition from childhood to adolescence seems to be a particularly vulnerable period for the development of anxiety symptoms and disorders. (Source: Psychoneuroendocrinology)

Alcohol consumption is positively associated with fasting serum ghrelin in non-dependent adults: Results from the population-based LIFE-Adult-Study
Ghrelin is a 28-amino acid peptide hormone, which is predominantly synthesized in the stomach. A multitude of potential functions of ghrelin has been described including potent effects on different endocrine axes (Kluge et al., 2007 2010b, 2013; Takaya et al., 2000) as well as various other peripheral (e.g. increasing intestinal motility and cardiac output (M üller et al., 2015)) and central effects, e.g. on sleep (Kluge et al., 2010a) or learning (Diano et al., 2006).

Glucocorticoid receptor exon 1F methylation and the cortisol stress response in health and disease
Stress is arguably the most common environmental factor leading to psychopathology (Smoller, 2016), and its effects are especially detrimental when occurring during childhood (Carr et al., 2013; Nanni et al., 2012). This persisting impact of stress during development is thought to be partially mediated by epigenetic mechanisms. A seminal study in 2004 proposed the 1F region of the glucocorticoid receptor (GR) to be of crucial importance in this context (Weaver et al., 2004). Pups of low licking-grooming dams showed higher methylation in the rat ortholog of the 1F region, which was linked to impaired feedback by corticoster...

Pathophysiology in a model of Gulf War Illness: Contributions of pyridostigmine bromide and stress
The Gulf War was unusual in its use of pyridostigmine bromide (PB) as prophylactic treatment against toxicity from nerve gas agents. However, this prophylactic treatment along with the stress of deployment may have caused unexpected alterations in neural and immune function, resulting in a host of cognitive deficits which are a component of symptoms now clinically termed Gulf War Illness (GWI). Although GWI is considered a unique diagnosis for veterans deployed in the Gulf War, symptomology of GWI parallels symptoms of other conditions in civilian populations, including chronic fatigue syndrome (CFS), major depressive diso...

Prenatal and postnatal cortisol and testosterone are related to parental caregiving quality in fathers, but not in mothers
The quality of parental caregiving is a critical factor in a child ’s cognitive and social-emotional development, with insensitive caregiving practices increasing the risk for developing various types of psychopathology (Gilbert et al., 2009; Keyes et al., 2012; Morris et al., 2013; Pechtel and Pizzagalli, 2011). It is therefore of great importance to understand the underlying factors that bring forth variation in parents’ caregiving quality, including endocrine factors (Bos, 2017; Feldman, 2015; Rilling, 2013).

Sexual Orientation and Salivary Alpha-Amylase Diurnal Rhythms in a Cohort of U.S. Young Adults
Sexual orientation-related physical and mental health disparities have been well-documented in the United States. Sexual minorities report greater prevalence of depressive and anxious symptoms, post-traumatic stress disorder (PTSD), disordered eating, and other adverse health outcomes compared with heterosexual populations (Institute of Medicine, 2011). Both stress and attachment paradigms suggest that health inequities adversely affecting sexual minorities result from social stigmatization enacted through discrimination, harassment, abuse, and violence (Minority Stress Theory) (Meyer, 2003; Rosario et al., 2002) and from ...

Omega-3 polyunsaturated fatty acid levels and dysregulations in biological stress systems
Omega-3 (n-3) polyunsaturated fatty acids (PUFAs) consist of e.g. α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and are primarily found in fatty fish, along with some other seafood, and certain nuts and seeds (Simopoulos, 1999). N-3 PUFAs have anti-inflammatory properties and are suggested to positively influence brain functi oning (Smith et al., 2011). Low levels of n-3 PUFAs are observed in patients with several somatic or mental disorders, and accordingly several intervention studies have found a beneficial effect of n-3 PUFA supplementation on, for example, cardiovascular dis...

A P2X7 receptor antagonist reverses behavioural alterations, microglial activation and neuroendocrine dysregulation in an unpredictable chronic mild stress (UCMS) model of depression in mice
Depression is a major public health challenge that has been the focus of intense research in the past. In 2010, in the Global Burden of Disease study, depressive disorders were found to be the 2nd leading cause of years lived with disability, and depression will rise to become the leading cause of disability by 2030 worldwide (Mathers and Loncar, 2006). The pathophysiology of depression is explained mainly on the basis of alterations in neuroplasticity and metabolism of monoamines. Though these theories have been translated into pharmacotherapy, 100% remission rates have still not been achieved (Santarelli et al., 2003). (...

Influence of pre-existing hypertension on neuroendocrine and cardiovascular changes evoked by chronic stress in female rats
Clinical and preclinical studies have indicated that the complications related to stress are determined by characteristics of the aversive stimulus, such as type, duration, frequency, controllability, and intensity (Crestani, 2016; Koolhaas et al., 2011; Steptoe and Kivim äki, 2012). The influence of predictability on animal models has been investigated by comparing the effects of chronic stressors involving daily exposure to the same type of aversive stimuli (i.e., homotypic/predictable) versus different stressors (i.e., heterotypic/unpredictable) (Crestani, 2016).

Elevated salivary alpha-amylase levels at awakening in patients with depression
Major depressive disorder (MDD) is one of the most common psychiatric disorders and the leading cause of disability worldwide (WHO, 2017). Despite extensive research, no specific biomarkers for MDD have been identified to date (Fried& Nesse, 2015). Although the mean level of salivary cortisol (SC; a hormone reflecting hypothalamus-pituitary-adrenal (HPA) axis activity) has often been found to be elevated in patients with mood, anxiety, and somatic disorders (MAS-disorders), this possible biomarker lacks the potential to distinguish among these disorders (Rief et al., 1998; Hellhammer et al., 2009).

Social-Evaluative Threat, Cognitive Load, and the Cortisol and Cardiovascular Stress Response
The social self-preservation model contends that humans are motivated to preserve the social self, or to maintain social esteem, acceptance, status, and value (Dickerson et al., 2004; Dickerson& Kemeny, 2004). Prototypical threats to this central goal are social-evaluative threats, or conditions in which an important aspect of self-identity is or could be negatively judged by others (Dickerson& Kemeny, 2004). We propose that these social-evaluative situations elicit a coordinated psychobiological response, including increases in cortisol. (Source: Psychoneuroendocrinology)

Early-life socioeconomic disadvantage, not current, predicts accelerated epigenetic aging of monocytes
Aging-related chronic diseases such as heart disease, diabetes, and cancer are among the leading causes of death worldwide. Morbidity and mortality from these conditions are disproportionately high among socioeconomically disadvantaged individuals (Braveman& Barclay, 2009). Although much evidence comes from studies of socioeconomic status (SES) during adulthood, accumulating data suggest early-life SES is also associated with age-related health problems. Independent of adulthood SES, early-life SES confers increased risk for upper respiratory infection, premature death, and morbidity and mortality from cardiovascular d...

Depressive Symptoms and Adipokines in Women: Study of Women ’s Health Across the Nation
Major depressive disorder (MDD) and depressive symptoms have been linked to obesity, metabolic syndrome, insulin resistance, and diabetes (Everson et al., 2002; Everson-Rose et al., 2004; Golden et al., 2004), all of which are metabolic risk factors that increase risk for cardiovascular disease (CVD). A potential pathophysiologic pathway by which depression influences metabolic dysregulation is inflammation (Stewart et al., 2009; Rethorst et al., 2014). Clear associations have been reported between depression and C-reactive protein (CRP), interleukin 6 (IL-6), fibrinogen, and tumor necrosis factor alpha (TNF-a) (Maes, 1999...
