Systematic review, meta-analysis of basal cortisol levels in Borderline Personality Disorder compared to non-psychiatric controls
Borderline personality disorder (BPD) is a debilitating psychiatric illness that is common in both the general population and in clinical settings, with a life-time prevalence of 5.9% (Grant et al., 2008; Lenzenweger et al., 2007). BPD is characterised by a pervasive pattern of instability of interpersonal relationships, self-image and affects, and marked impulsivity beginning by early adulthood. These symptoms must persist and cause marked distress and or functional impairment within a variety of contexts, although symptoms often fluctuate markedly over short periods of time (Association, A.P.

Post-learning Stress Reduces the Misinformation Effect: Effects of Psychosocial Stress on Memory Updating
Episodic memory representations can be altered after learning new and related information (for a review: Lee et al., 2017). This characteristic of memory can be viewed as adaptive because it allows encoded memories to be modified and updated with relevant information (Nader and Hardt, 2009; Schacter et al., 2011). However, it can also lead to distortions, causing false memories. One of the most prominent presentations of memory distortion is the misinformation effect, when misleading information presented after an event changes the memory of that original event (Loftus, 2005).

Chronic stress exposure and daily stress appraisals relate to biological aging marker p16INK4a
An emergent literature suggests that exposure to adverse social conditions is associated with accelerated biological aging, offering one mechanism through which adversity may increase risk for age-related diseases, including diabetes, atherosclerosis, neurodegeneration, and cancer. Chronic stress, via prolonged or repeated activation of the sympathoadrenal system, is thought to increase disease risk through its cumulative impact on key biological aging pathways (Epel, 2009; Robles and Carroll, 2011; Shalev et al., 2014).

Sociodemographic Correlates of Change in Leukocyte Telomere Length during Mid- to Late-Life: The Multi-Ethnic Study of Atherosclerosis
Telomere attrition is a hallmark indicator of biological aging (Kennedy et al., 2014; Lopez-Otin et al., 2013), and leukocyte telomere length has been proposed as a biomarker of aging (Aubert and Lansdorp, 2008). Telomeres cap the ends of chromosomes and promote chromosomal stability (Blackburn et al., 2015). Due to the end replication problem, telomeres naturally shorten with mitosis (Blackburn, 2005). Oxidative damage and DNA replication stress also contribute to telomere loss (Blackburn et al., 2015; von Zglinicki, 2002). (Source: Psychoneuroendocrinology)

Altered Hypothalamus-Pituitary-Adrenal Axis Function: A Relevant Factor in the Comorbidity of Atopic Eczema and Attention Deficit/Hyperactivity Disorder?
Atopic eczema (AE) is a chronic inflammatory skin disease with key symptoms such as eczematous and inflammatory eruptions of the skin and intense pruritus (Brown, 2016; Lawton, 2014). AE typically manifests in early infancy (with an onset before the age of 5 in 90% of the patients) and represents one of the most common chronic childhood disorders (Weidinger and Novak, 2016). Notably, about 50% of all individuals with AE have specific allergic sensitization indicating that atopy is not a necessary feature of AE (Flohr et al., 2004). (Source: Psychoneuroendocrinology)

Genetic and Peripheral Markers of the Oxytocin System and Parental Care Jointly Support the Cross-Generational Transmission of Bonding across Three Generations
Studies have repeatedly shown that oxytocin (OT), a nine-amino-acid neuropeptide synthesized in the hypothalamus, plays a critical role in human social affiliations and in the formation of attachment bonds, particularly the parent-infant bond (Feldman et al., 2011; Feldman et al., 2007; Gordon et al., 2010). Children experiencing high-quality caregiving from their parents, as measured by direct observations of sensitive parenting that is characterized by enhanced positive affect, social gaze, affectionate touch, and warm vocalizations, showed higher levels of peripheral OT and better social competencies (Feldman et al., 20...

Altered overnight levels of pro-inflammatory cytokines in men and women with posttraumatic stress disorder
Posttraumatic Stress Disorder (PTSD) is a debilitating condition with a lifetime prevalence of approximately 8% (Kessler et al., 1995). In addition to severely impairing psychological wellbeing, PTSD is associated with increased risk for cardiovascular, autoimmune and metabolic disorders, and premature mortality (Boscarino, 2006; Cohen et al., 2009, O ’Donovan et al., 2015). Inflammation can drive the development of multiple physical diseases and has been proposed as a mechanism linking PTSD with ill health (O’Donovan et al., 2013). (Source: Psychoneuroendocrinology)

Effects of internet-based stress management on acute cortisol stress reactivity: preliminary evidence using the Trier Social Stress Test (TSST)
Chronic stress has been associated with several somatic diseases, such as hypertension, cardiovascular illness including myocardial infarction, stroke, and depression (Cohen et al., 2007). Although the mechanisms by which chronic stress can increase vulnerability and ultimately contribute to illness are not fully understood, heightened reactivity of physiological systems to everyday stressors or an impaired ability to recover from acute stress have been discussed as mediating factors within the allostatic load model (McEwen, 1998).

Daily oxytocin patterns in relation to psychopathy and childhood trauma in residential youth
Oxytocin is a neuropeptide that has received much attention due its relation to social behaviors, such as social affiliation, pair bonding, emotion recognition, trust, empathy, altruism, and attachment (Campbell, 2008, 2010; Lee et al., 2009a; Veening& Olivier, 2013). Several approaches have been proposed to better understand the underlying mechanisms of oxytocin in social behaviors. Particularly, it has been suggested that oxytocin might play a role in the development of the social brain as it is involved in the processing of social sensory input in the neocortex during the first postnatal years (Vaidyanathan& Ham...

Detection of Estradiol in Rat Brain Tissues: Contribution of Local Versus Systemic Production
Estrogens have important effects on brain structure, function and behavior. Estrogens influence not only reproductive behaviors, but also affect mood, cognitive performance, synaptic plasticity, neurodegenerative disease, and functional recovery following brain injury (Erickson et al., 2007; Garcia-Segura, 2008; Gibbs, 2010; Greene, 2000; Sherwin and Henry, 2008; Walf and Frye, 2006).

Temporal dynamics of cortisol-associated changes in mRNA expression of glucocorticoid responsive genes FKBP5, GILZ, SDPR, PER1, PER2 and PER3in healthy humans
The glucocorticoid cortisol, regulated by the hypothalamus-pituitary-adrenal (HPA) axis, plays an essential role in both stress-related and baseline homeostasis. In peripheral tissues, it exerts its function mainly through binding to the glucocorticoid receptor (GR), encoded by NR3C1. The GR is a ligand-activated transcription factor predominantly located in the cytoplasm in a multiprotein complex consisting of chaperones and co-chaperones (Wochnik et al., 2005). Activation of the GR leads to up- and down-regulation of target gene expression, both through direct interaction between activated GR dimers and glucocorticoid re...

Investigating associations between momentary stress and cortisol in daily life: What have we learned so far?
Psychosocial stress reliably activates the hypothalamic-pituitary-adrenocortical (HPA) axis, resulting in elevations of circulating cortisol. Kirschbaum et al. (1993) demonstrated this psychoneuroendocrinological association using a specific laboratory-based motivated performance-related stressor in a social-evaluative setting including uncontrollability, the Trier Social Stress Test (TSST). A meta-analysis later demonstrated that TSST-like stressors were indeed the most potent activators of cortisol responses to stress when compared to other stressors such as cognitive tasks, noise exposure or emotion induction without un...

Resting Amygdala Connectivity and Basal Sympathetic Tone as Markers of Chronic Hypervigilance
Hypervigilance is a behavioral, cognitive, and physiological state of sustained hyperarousal and alertness for potential threat. The cognitive component of hypervigilance (i.e., increased alertness) is mediated by activation of threat-detection neural circuitry centered around the amygdala (e.g., Yoon& Weierich, 2016), whereas its physiological component (i.e., elevated arousal) is mediated by activation of the neuroendocrine stress systems (e.g., Pole et al., 2007). In potentially dangerous situations, hypervigilance is adaptive, as it facilitates threat detection when an actual threat appears and enables a prompt res...

Associations Between Symptoms of Depression and Anxiety and Cortisol Responses to and Recovery from Acute Stress
The ability to rapidly and adaptively respond to environmental threats and stressors is critical to survival. Interactive physiological responses involving the hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous systems influence metabolic, immune, and cardiovascular parameters in order to aid the body in responding appropriately to environmental demands (McEwen, 1998). This process of achieving stability through change, first introduced by Sterling and Eyer (Sterling and Eyer, 1988), is known as ‘allostasis’. (Source: Psychoneuroendocrinology)

Hair and fingernail cortisol and the onset of acute coronary syndrome in the middle-aged and elderly men
Acute psychosocial stress triggers an activation of the hypothalamic-pituitary-adrenal axis, which causes the adrenal cortex to secrete cortisol. Traditionally, cortisol has been measured in blood and saliva samples, which revealed hormone levels for a short time period. Recently, cortisol has been reportedly measured in hair samples (Russell et al., 2012). Scalp hair grows at an average rate of 1.0 cm/month; 1.0 cm of scalp hair may be used to determine the level of the hormone secreted during a period of 1 month. (Source: Psychoneuroendocrinology)

Modulation of histaminergic activity has been shown to be involved in several physiological functions, such as circadian rhythm, energy homeostasis, sensory and motor functions, cognition, and attention, which are affected in several central nervous system(CNS) disorders (Haas and Panula, 2003; Leurs et al., 2005). All actions of histamine (HA) are orchestrated by four HA receptors, H1-H4R, which are members of the G-protein-coupled receptor (GPCR) family (Haas and Panula, 2003). Out of four HA receptors, H3R is of particular interest concerning CNS functions. (Source: Psychoneuroendocrinology)

Basal testosterone ’s relationship with dictator game decision-making depends on cortisol reactivity to acute stress: A dual-hormone perspective on dominant behavior during resource allocation
As a species, we have evolved in social hierarchies, and the stratification of individuals within human groups helps organize us and maintain social order (Anderson et al., 2015; Ellis, 1994; Sapolsky, 2000). Within a social hierarchy, having higher status - respect or deference that is based on an individual ’s perceived social value (Anderson et al., 2015; Magee and Galinsky, 2008) - grants several benefits, such as access to limited resources and social influence over others (Cheng et al., 2013; Sapolsky, 2000).

Epigenetics of the Molecular Clock and Bacterial Diversity in Bipolar Disorder
Bipolar Disorder (BD) is a mood disorder, which is characterized by recurrent manic, depressive or mixed episodes. Even though many potential pathomechanisms of BD have been identified over the last decades, it is still largely unknown how these disease mechanisms interact with each other. Neurotransmitter dysbalances, neurotrophic factor imbalances, chronic inflammation, oxidative stress and disturbed circadian rhythms have been put forward as putative underlying mechanisms (Boland et al., 2012; Andreazza et al., 2008; Berk et al., 2011; Bengesser and Reininghaus, 2013; Tsai et al., 2012; Soczynska et al., 2011; Kapczinsk...

Virtually Stressed? A refined virtual reality adaptation of the Trier Social Stress Test (TSST) induces robust endocrine responses
Over the last decades a number of highly standardized laboratory stressors have been developed to induce psychosocial stress in the laboratory (e.g. the Socially-Evaluated Cold Pressor Test, SECPT, (Schwabe et al., 2013); Maastricht Acute Stress Test, MAST, (Smeets et al., 2012). Among these protocols, the Trier Social Stress Test (TSST; Kirschbaum et al., 1993) has become widely used in psychobiological stress research as it has been proven to evoke robust endocrine and cardiovascular responses in the majority of participants.

Increased frequency of mind wandering in healthy women using oral contraceptives
Oral contraceptives (OC) are the most common type of contraceptive method used in industrialized countries (Daniels et al., 2015). It is estimated that 26% of women who are of reproductive age currently use OC and 82% of women report using it at some point in their lives (Daniels and Mosher, 2013). Around 10% of OC users report experiencing mood side effects (e.g., depressive symptoms, irritability (Kelly et al., 2010), which are common reasons for OC cessation (Rosenberg and Waugh, 1998; Westhoff et al., 2007).

Stress reactivity in preschool-aged children: Evaluation of a social stress paradigm and investigation of the impact of prenatal maternal stress
In animals and humans, prenatal maternal stress (PS) has impact on birth outcomes, development and stress regulation as well as disease in the offspring (e.g., Stein et al., 2014; Van den Bergh et al., 2017). The intrauterine environment contributes to long-term consequences particularly via epigenetic modifications —a process referred to as prenatal programming (Sosnowski et al., 2018). While the importance of PS is well-established, its precise mechanisms and the timing of its effects are still within the scope of current research. (Source: Psychoneuroendocrinology)

Withdrawal of plasma estradiol is associated with increased anxiety reported by women in the first 12 hours after delivery
Transient mood changes, also known as postpartum blues, occur in 15 to 85% of women in the immediate puerperium (Henshaw, 2003) and are usually described as predictors of postpartum depression (DPP) (Reck et al., 2009). DPP is a severe condition affecting around 10 to 22% of the mothers (Gaynes et al., 2005). In recent reviews investigating predictors of postpartum depression, besides the role of postpartum blues and environmental stressors, hormonal changes were addressed as possible important biomarkers for this period (Garcia-Leal et al., 2017; Guintivano et al., 2018).

Low vagal tone in two rat models of psychopathology involving high or low corticosterone stress responses
One of the current challenges in mental health research is the identification of risk factors and mechanisms related to individual vulnerability to develop psychopathologies (Weger and Sandi, 2018). Given the well-known impact of stress in triggering and exacerbating psychopathologies (de Kloet et al., 2016; McEwen et al., 2012), a great deal of research is concentrating on understanding the role of the major physiological stress systems [i.e., the autonomic nervous system (ANS) and the hypothalamic-pituitary-adrenocortical (HPA) axis] in this context (Carnevali et al., 2018; de Kloet et al., 2005; Pruessner et al., 1997; ...

Cross-sectional relationship between kynurenine pathway metabolites and cognitive function in major depressive disorder
Major depressive disorder (MDD) is one of the most prevalent and disabling psychiatric illness, with a high lifetime prevalence ranging from 10-15% (Kessler et al., 2005, 2013a). Cognitive dysfunction is a core diagnostic feature of MDD and is likely to cause considerable interference and functional impairment in patients' daily life function (Mcintyre et al., 2013), but effective alleviation of the cognitive deficits is difficult to achieve with current antidepressant therapies (Amado-Boccara et al., 1995).

Memories of and influenced by the Trier Social Stress Test
Stress has obtained a rather bad reputation nowadays. It is often related to impaired cognitive performance and when occurring chronically it is commonly associated with physical and mental health problems. However, research has illustrated that the impact of stress on cognitive functions such as learning and memory are far more complex than initially assumed. Stress may enhance or impair memory depending on several key modulators and mediators. Both quantitative and qualitative shifts take place (Schwabe& Wolf, 2013). (Source: Psychoneuroendocrinology)

Hpa axis responses to psychological challenge linking stress and disease: what do we know on sources of intra- and interindividual variability?
Chronic stress is a major risk factor for several disorders, including highly prevalent diseases such as depression, anxiety disorders, cardiovascular diseases, and the metabolic syndrome (see 3.8 and 3.9). Since the finding of a disinhibited hypothalamic-pituitary-adrenal (HPA) axis in depressed patients (Carroll et al., 1980), it was assumed that alterations in the activity of this system may be a close correlate of stress-related pathology. The HPA axis is a core component of the neuroendocrine stress response. (Source: Psychoneuroendocrinology)
