Adolescent stress sensitizes the adult neuroimmune transcriptome and leads to sex-specific microglial and behavioral phenotypes. Neuropsychopharmacology 2021; 46:949-958. [PMID: 33558677 PMCID: PMC8115118 DOI: 10.1038/s41386-021-00970-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 01/11/2021] [Accepted: 01/13/2021] [Indexed: 01/30/2023]
Abstract
Adolescent exposure to chronic stress, a risk factor for mood disorders in adulthood, sensitizes the neuroinflammatory response to a subsequent immune challenge. We previously showed that chronic adolescent stress (CAS) in rats led to distinct patterns of neuroimmune priming in adult male and female rats. However, sex differences in the neuroimmune consequences of CAS and their underlying mechanisms are not fully understood. Here we hypothesized that biological sex would dictate differential induction of inflammation-related transcriptomic pathways and immune cell involvement (microglia activation and leukocyte presence) in the hippocampus of male and female rats with a history of CAS. Adolescent rats underwent CAS (six restraint and six social defeat episodes during postnatal days 38-49), and behavioral assessments were conducted in adolescence and adulthood. Neuroimmune measures were obtained following vehicle or a systemic lipopolysaccharide (LPS) challenge in adulthood. CAS led to increased time in the corners of the open field in adolescence. In males, CAS also increased social avoidance. As adults, CAS rats displayed an exaggerated enrichment of the nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) pathway and chemokine induction following LPS challenge, and increased number of perivascular CD45+ cells in the hippocampus. However, CAS females, but not males, showed exaggerated glucocorticoid receptor (GR) pathway enrichment and increased microglial complexity. These results provide further insight to the mechanisms by which peripheral immune events may influence neuroimmune responses differentially among males and females and further demonstrate the importance of adolescent stress in shaping adult responses.

Abstract
The increased incidence of opioid use during pregnancy warrants investigation to reveal the impact of opioid exposure on the developing fetus. Exposure during critical periods of development could have enduring consequences for affected individuals. Particularly, evidence is mounting that developmental injury can result in immune priming, whereby subsequent immune activation elicits an exaggerated immune response. This maladaptive hypersensitivity to immune challenge perpetuates dysregulated inflammatory signaling and poor health outcomes. Utilizing an established preclinical rat model of perinatal methadone exposure, we sought to investigate the consequences of developmental opioid exposure on in vitro activation of peripheral blood mononuclear cells (PBMCs). We hypothesize that PBMCs from methadone-exposed rats would exhibit abnormal chemokine and cytokine expression at baseline, with exaggerated chemokine and cytokine production following immune stimulation compared to saline-exposed controls. On postnatal day (P) 7, pup PMBCs were isolated and cultured, pooling three pups per n. Following 3 and 24 h, the supernatant from cultured PMBCs was collected and assessed for inflammatory cytokine and chemokine expression at baseline or lipopolysaccharide (LPS) stimulation using multiplex electrochemiluminescence. Following 3 and 24 h, baseline production of proinflammatory chemokine and cytokine levels were significantly increased in methadone PBMCs (p < 0.0001). Stimulation with LPS for 3 h resulted in increased tumor necrosis factor (TNF-α) and C-X-C motif chemokine ligand 1 (CXCL1) expression by 3.5-fold in PBMCs from methadone-exposed PBMCs compared to PBMCs from saline-exposed controls (p < 0.0001). Peripheral blood mononuclear cell hyperreactivity was still apparent at 24 h of LPS stimulation, evidenced by significantly increased TNF-α, CXCL1, interleukin 6 (IL-6), and IL-10 production by methadone PMBCs compared to saline control PBMCs (p < 0.0001). Together, we provide evidence of increased production of proinflammatory molecules from methadone PBMCs at baseline, in addition to sustained hyperreactivity relative to saline-exposed controls. Exaggerated peripheral immune responses exacerbate inflammatory signaling, with subsequent consequences on many organ systems throughout the body, such as the developing nervous system. Enhanced understanding of these inflammatory mechanisms will allow for appropriate therapeutic development for infants who were exposed to opioids during development. Furthermore, these data highlight the utility of this in vitro PBMC assay technique for future biomarker development to guide specific treatment for patients exposed to opioids during gestation.

Abstract
Adversity during development is a reliable predictor of psychiatric disorders such as depression and anxiety which are increasingly recognized to have an immune component. We have previously demonstrated that chronic adolescent stress (CAS) in rats leads to depressive-like behavior in adulthood along with long-lasting changes to the hypothalamic-pituitary-adrenal axis and pro-inflammatory cytokine induction in the hippocampus. However, the mechanisms by which CAS promotes hippocampal inflammation are not yet defined. Here we tested the hypothesis that a history of CAS exaggerates induction of the pro-inflammatory NFκB pathway in the adult rat hippocampus without compromising the peripheral immune response. We also assessed potential sex differences because it is unclear whether females, who are twice as likely to suffer from mood disorders as males, are disproportionally affected by stress-primed inflammation. Male and female adolescent rats underwent a CAS paradigm or received no stress. Six weeks following the last stressor, all rats received a single systemic injection of either lipopolysaccharide or vehicle to unmask possible immune-priming effects of CAS. An NFκB signaling PCR array demonstrated that CAS exaggerated the expression of NFκB-related genes in the hippocampus of both males and females. Interestingly, targeted qPCR demonstrated that CAS potentiated the induction of hippocampal IL1B and REL mRNA in female rats only, suggesting that some immune effects of CAS are indeed sex-specific. In contrast to the hippocampal findings, indices of peripheral inflammation such as NFκB activity in the spleen, plasma IL-1β, IL-6, TNF-α, and corticosterone were not impacted by CAS in female rats. Despite showing no pro-inflammatory changes to hippocampal mRNA, male CAS rats displayed lower plasma corticosterone response to LPS at 2 h after injection followed by an exaggerated plasma IL-1β response at 4 h. This potentially blunted corticosterone response coupled with excessive innate immune signaling in the periphery is consistent with possible glucocorticoid resistance in males. In contrast, the effects of CAS manifested as excessive hippocampal immune reactivity in females. We conclude that while a history of exposure to chronic adolescent stress enhances adult immune reactivity in both males and females, the mechanism and manifestation of such alterations are sex-specific.

Abstract
OBJECTIVE Childhood maltreatment (CM) has been associated with several diseases in adult life, including diabetes, obesity and mental disorders. Inflammatory conditions have been postulated as possible mediators of this relationship. The aim was to conduct a systematic review regarding the association between CM and inflammatory markers in adulthood. METHOD A literature search of the PubMed, ISI, EMBASE and PsychINFO databases was conducted. The key terms used were as follows: 'Child Maltreatment', 'Childhood Trauma', 'Early Life Stress', 'Psychological Stress', 'Emotional Stress', 'Child Abuse' and 'Child Neglect'. They were cross-referenced separately with the terms: 'C-reactive Protein (CRP)', 'Tumor Necrosis Factor', 'Cytokine', 'Interleukin', 'Inflammatory' and 'Inflammation'. RESULTS Twenty articles remained in the review after exclusion criteria were applied. Studies showed that a history of CM was associated with increased levels of CRP, fibrinogen and proinflammatory cytokines. Increased levels of circulating CRP in individuals with a history of CM were the most robust finding among the studies. Data about anti-inflammatory mediators are still few and inconsistent. CONCLUSION Childhood maltreatment is associated with a chronic inflammatory state independent of clinical comorbidities. However, studies are heterogeneous regarding CM assessment and definition. Important methodological improvements are needed to better understand the potential impact of CM on inflammatory response.

Abstract
BACKGROUND Recent changes in clinical guideline recommendations for age of breast cancer screening initiation highlighted the potential psychological ramifications associated with screening. This study examined the feasibility, acceptability, and preliminary efficacy of a brief Relaxation Response training (RRT) to decrease distress among women undergoing breast biopsy. METHODS Women scheduled for percutaneous core-needle biopsy were recruited into a single-arm RRT trial, including 3 individual sessions. Psychosocial assessments were completed pre- and postintervention. RESULTS Forty women were enrolled between 6/1/10 and 8/31/11. Among enrollees, 75% completed all 3 RRT sessions, and 75% completed the post-assessment. Participants showed significant reductions in acute distress following each RRT session. Qualitative feedback indicated a positive impact of RRT on clinic care experiences. CONCLUSIONS RRT is a portable intervention that was feasible to implement, acceptable to patients and associated with significant decreases in acute emotional distress during the period of diagnostic uncertainty related to percutaneous breast biopsy.

Abstract
The relaxation response (RR) is the counterpart of the stress response. Millennia-old practices evoking the RR include meditation, yoga and repetitive prayer. Although RR elicitation is an effective therapeutic intervention that counteracts the adverse clinical effects of stress in disorders including hypertension, anxiety, insomnia and aging, the underlying molecular mechanisms that explain these clinical benefits remain undetermined. To assess rapid time-dependent (temporal) genomic changes during one session of RR practice among healthy practitioners with years of RR practice and also in novices before and after 8 weeks of RR training, we measured the transcriptome in peripheral blood prior to, immediately after, and 15 minutes after listening to an RR-eliciting or a health education CD. Both short-term and long-term practitioners evoked significant temporal gene expression changes with greater significance in the latter as compared to novices. RR practice enhanced expression of genes associated with energy metabolism, mitochondrial function, insulin secretion and telomere maintenance, and reduced expression of genes linked to inflammatory response and stress-related pathways. Interactive network analyses of RR-affected pathways identified mitochondrial ATP synthase and insulin (INS) as top upregulated critical molecules (focus hubs) and NF-κB pathway genes as top downregulated focus hubs. Our results for the first time indicate that RR elicitation, particularly after long-term practice, may evoke its downstream health benefits by improving mitochondrial energy production and utilization and thus promoting mitochondrial resiliency through upregulation of ATPase and insulin function. Mitochondrial resiliency might also be promoted by RR-induced downregulation of NF-κB-associated upstream and downstream targets that mitigates stress.

Abstract
OBJECTIVE To investigate the dys-psychological stress effect on the growth of subcutaneous xenotransplanted tumor in nude mice bearing human epithelium ovarian carcinoma, and the influence on P53 and NFκBp65 expressions. METHODS The subcutaneous tumor xenografts were established by implanting human epithelium ovarian carcinoma tissues into nude mice and the dys-psychological stress model was established with restraint. The mice were randomized into the following four treatment groups with each group six mice respectively: tumor group (group A), normal saline intraperitoneal injection; tumor with stress group (group B), normal saline intraperitoneal injection; tumor therapy group (group C), cisplatin intraperitoneal injection; and tumor therapy with stress group (group D), cisplatin intraperitoneal injection. The expressions of P53 and NFκBp65 in tumor tissues were determined by Western blotting. RESULTS The expressions of P53 and NFκBp65 in each restraint group were enhanced compared with the control groups (P<0.05). CONCLUSION The dys-psychological stress may induce the high expressions of P53 and NFκBp65 proteins and further promote tumor growth.

Abstract
Introduction This pilot study used a prospective longitudinal design to compare the effect of adjuvant whole breast radiation therapy (WBRT) versus partial breast radiation therapy (PBRT) on fatigue, perceived stress, quality of life and natural killer cell activity (NKCA) in women receiving radiation after breast cancer surgery. Methods Women (N = 30) with early-stage breast cancer received either PBRT, Mammosite brachytherapy at dose of 34 Gy 10 fractions/5 days, (N = 15) or WBRT, 3-D conformal techniques at dose of 50 Gy +10 Gy Boost/30 fractions, (N = 15). Treatment was determined by the attending oncologist after discussion with the patient and the choice was based on tumor stage and clinical need. Women were assessed prior to initiation of radiation therapy and twice after completion of radiation therapy. At each assessment, blood was obtained for determination of NKCA and the following instruments were administered: Perceived Stress Scale (PSS), Functional Assessment of Cancer Therapy-Fatigue (FACT-F), and Functional Assessment of Cancer Therapy-General (FACT-G). Hierarchical linear modeling (HLM) was used to evaluate group differences in initial outcomes and change in outcomes over time. Results Fatigue (FACT-F) levels, which were similar prior to radiation therapy, demonstrated a significant difference in trajectory. Women who received PBRT reported progressively lower fatigue; conversely fatigue worsened over time for women who received WBRT. No difference in perceived stress was observed between women who received PBRT or WBRT. Both groups of women reported similar levels of quality of life (FACT-G) prior to initiation of radiation therapy. However, HLM analysis revealed significant group differences in the trajectory of quality of life, such that women receiving PBRT exhibited a linear increase in quality of life over time after completion of radiation therapy; whereas women receiving WBRT showed a decreasing trajectory. NKCA was also similar between therapy groups but additional post hoc analysis revealed that better quality of life significantly predicted higher NKCA regardless of therapy. Conclusions Compared to WBRT, PBRT results in more rapid recovery from cancer-related fatigue with improved restoration of quality of life after radiation therapy. Additionally, better quality of life predicts higher NKCA against tumor targets, emphasizing the importance of fostering quality of life for women undergoing adjuvant radiation therapy.

Abstract
Physical and psychological stressors reduce natural killer cell function. This reduction in cellular function results from stress-induced release of glucocorticoids. Glucocorticoids act upon natural killer cells to deacetylate and transrepress immune response genes through epigenetic processes. However, other than the glucocorticoid receptor, the proteins that participate in this process are not well described in natural killer cells. The purpose of this study was to identify the proteins associated with the glucocorticoid receptor that are likely epigenetic participants in this process. Treatment of natural killer cells with the synthetic glucocorticoid, dexamethasone, produced a significant time dependent reduction in natural killer cell activity as early as 8h post treatment. This reduction in natural killer cell activity was preceded by nuclear localization of the glucocorticoid receptor with histone deacetylase 1 and the corepressor, SMRT. Other class I histone deacetylases were not associated with the glucocorticoid receptor nor was the corepressor NCoR. These results demonstrate histone deacetylase 1 and SMRT to associate with the ligand activated glucocorticoid receptor within the nuclei of natural killer cells and to be the likely participants in the histone deacetylation and transrepression that accompanies glucocorticoid mediated reductions in natural killer cell function.

Abstract
The molecular basis for psychosocial-distress mediated immune-dysregulation is not well understood. The purpose of this study was to determine whether peripheral blood mononuclear cell (PBMC) epigenetic pattern associates with this form of immune dysregulation. Women newly diagnosed with early stage breast cancer were enrolled into the study and psychosocial, immunological and epigenetic assessments were made at diagnosis and four months later, after completion of cancer treatment. At diagnosis women reported increased perceived stress, anxiety, and mood disturbance and the PBMC of these women exhibited reduced natural killer cell activity and reduced production of interferon gamma, which contrasted with results, obtained after completion of treatment. At the epigenetic level, a PBMC subset derived from women at diagnosis exhibited a distinct epigenetic pattern, with reduced nuclear acetylation of histone residues H4-K8 and H4-K12, as well as reduced phosphorylation of H3-S10, when compared to similar cells derived after the completion of treatment. Natural killer cell activity and interferon-gamma production were associated with nuclear acetylation and phosphorylation status of these histone residues. These findings demonstrate associations among nuclear epigenetic pattern and the immune dysregulation that accompanies psychosocial distress.

Abstract
It is well-established that psychological distress reduces natural killer cell activity (NKCA) and dysregulates cytokine balance. This may be mediated by stress-induced release of glucocorticoids, which have broad effects on the immune system, including the suppression of NKCA and alteration of cytokine production. The purpose of this study was to evaluate epigenetic mechanisms that may underlie the effect of glucocorticoids on NK cells, using the human NK cell line, NK92. Treatment of NK92 cells with the synthetic glucocorticoid, dexamethasone, at a concentration of 10⁻⁷M, produced a significant reduction in NKCA. Glucocorticoid inhibition was a consequence of not only a reduced capacity of the NK cells to bind to tumor targets but also a reduced production of granule constituents (perforin and granzyme B) with no detectable effect on granule exocytosis. Glucocorticoids also reduced the constitutive and the stimulated production of the cytokines, IL-6, TNF alpha and IFN gamma, and reduced the surface expression of LFA-1. Glucocorticoid treatment also reduced global histone acetylation, the acetylation of histone 4 lysine position 8, and the accessibility of the proximal promoters of perforin, interferon gamma and granzyme B. Histone acetylation was recovered by treatment of the NK cells with a histone deacetylase inhibitor, which also restored NKCA and IFN gamma production. These results demonstrate glucocorticoids to dysregulate NK cell function at least in part through an epigenetic mechanism, which reduces promoter accessibility through modification of histone acetylation status. This epigenetic modification decreases the expression of effector proteins necessary to the full functional activity of NK cells.

Abstract
Prostate cancer is a leading malignancy in men, and prostatectomy is widely used for its treatment. Psychological distress and pain are commonly experienced in the perioperative period, and both can contribute to suppression of the immune response to cancer. This study evaluated perioperative pain, psychological distress, and immune function in men undergoing prostatectomy. Men were evaluated prior to surgery, 1 and 2 days postoperatively and 4-6 weeks postoperatively. Compared to cancer-free men, the prostatectomy group reported increased perceived stress, depression, confusion, and anxiety prior to surgery. During the 2 postoperative days, mood disturbance and anxiety persisted and were accompanied by mild elevations in pain and reduced vigor. At 4-6 weeks postoperative, mood, pain, and immune function were similar to those of the cancer-free group; however, the prostatectomy group continued to report significant elevations in anxiety. Natural killer cell activity (NKCA) was significantly reduced on Day 1 after prostatectomy, but by postoperative Day 2, NKCA returned to a level similar to that of the cancer-free group. The reduction in NKCA was not accompanied by changes in circulating immune cells, demonstrating that this reduction represented a functional change in NKCA. No correlations between immune variables and pain or psychological variables were found, suggesting that the postoperative reduction in NKCA was likely the result of the physical stress of the surgical experience. Suppression of immune defenses during the critical postoperative period can place cancer patients at risk for nascent tumor seeding. Additional interventions are needed to reduce this risk.

Abstract
Background The use of gene expression in venous blood either as a pharmacodynamic marker in clinical trials of drugs or as a diagnostic test requires knowledge of the variability in expression over time in healthy volunteers. Here we defined a normal range of gene expression over 6 months in the blood of four cohorts of healthy men and women who were stratified by age (22–55 years and > 55 years) and gender. Methods Eleven immunomodulatory genes likely to play important roles in inflammatory conditions such as rheumatoid arthritis and infection in addition to four genes typically used as reference genes were examined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), as well as the full genome as represented by Affymetrix HG U133 Plus 2.0 microarrays. Results Gene expression levels as assessed by qRT-PCR and microarray were relatively stable over time with ~2% of genes as measured by microarray showing intra-subject differences over time periods longer than one month. Fifteen genes varied by gender. The eleven genes examined by qRT-PCR remained within a limited dynamic range for all individuals. Specifically, for the seven most stably expressed genes (CXCL1, HMOX1, IL1RN, IL1B, IL6R, PTGS2, and TNF), 95% of all samples profiled fell within 1.5–2.5 Ct, the equivalent of a 4- to 6-fold dynamic range. Two subjects who experienced severe adverse events of cancer and anemia, had microarray gene expression profiles that were distinct from normal while subjects who experienced an infection had only slightly elevated levels of inflammatory markers. Conclusion This study defines the range and variability of gene expression in healthy men and women over a six-month period. These parameters can be used to estimate the number of subjects needed to observe significant differences from normal gene expression in clinical studies. A set of genes that varied by gender was also identified as were a set of genes with elevated expression in a subject with iron deficiency anemia and another subject being treated for lung cancer.

Abstract
This investigation used a non-randomized controlled design to evaluate the effect and feasibility of a mindfulness based stress reduction (MBSR) program on immune function, quality of life (QOL), and coping in women recently diagnosed with breast cancer. Early stage breast cancer patients, who did not receive chemotherapy, self-selected into an 8-week MBSR program or into an assessment only, control group. Outcomes were evaluated over time. The first assessment was at least 10 days after surgery and prior to adjuvant therapy, as well as before the MBSR start-up. Further assessments were mid-MBSR, at completion of MBSR, and at 4-week post-MBSR completion. Women with breast cancer enrolled in the control group (Non-MBSR) were assessed at similar times. At the first assessment (i.e., before MBSR start), reductions in peripheral blood mononuclear cell NK cell activity (NKCA) and IFN-gamma production with increases in IL-4, IL-6, and IL-10 production and plasma cortisol levels were observed for both the MBSR and Non-MBSR groups of breast cancer patients. Over time women in the MBSR group re-established their NKCA and cytokine production levels. In contrast, breast cancer patients in the Non-MBSR group exhibited continued reductions in NKCA and IFN-gamma production with increased IL-4, IL-6, and IL-10 production. Moreover, women enrolled in the MBSR program had reduced cortisol levels, improved QOL, and increased coping effectiveness compared to the Non-MBSR group. In summary, MBSR is a program that is feasible for women recently diagnosed with early stage breast cancer and the results provide preliminary evidence for beneficial effects of MBSR; on immune function, QOL, and coping.

Abstract
PURPOSE The purpose of this randomized pilot was to determine feasibility of testing Reiki, a complementary therapy intervention, for women undergoing breast biopsy (BB). BACKGROUND Increasingly women face the possibility of BB, the definitive test for breast cancer. Psychological distress associated with BB includes anxiety and depression. Reiki was proposed as an intervention to decrease anxiety and promote relaxation. METHOD Thirty-two women scheduled for BB were randomized to Reiki intervention versus conventional care control. Anxiety and depression were evaluated using self-report questionnaires. FINDINGS Analysis found no significant mean differences between groups over time. Comparably low baseline anxiety levels (possible selection bias) decreased naturally with time allowing little room for observing treatment effect. CONCLUSIONS Reiki, when administered in the naturalistic setting of a complementary therapy office, did not suggest evidence of efficacy. An intervention offered within the bounds of the conventional care setting may be more feasible for addressing BB distress.

Abstract
OBJECTIVE To address how interactions between polyunsaturated fatty acid (PUFA) levels and depressive symptoms were related to proinflammatory cytokine synthesis. Depression and stress promote proinflammatory cytokine production. Dietary intakes of omega-3 (n-3) and omega-6 (n-6) PUFAs also influence inflammation; high n-6:n-3 ratios enhance proinflammatory cytokine production, although n-3 has anti-inflammatory properties. METHODS Blood samples from 43 older adults (mean age = 66.67 years, SD = 10.09) provided data on PUFAs and tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-6 soluble receptor (sIL-6r). Depressive symptoms were assessed by the Center for Epidemiological Studies Depression Scale. RESULTS Depressive symptoms and n-6:n-3 ratios worked together to enhance proinflammatory cytokines beyond the contribution provided by either variable alone, with substantial variance explained by their interaction: 13% for IL-6 and 31% for TNF-alpha, whereas full models accounted for 18% and 40%, respectively. Although predicted cytokine levels were consistent across n-6:n-3 ratios with low depressive symptoms, higher n-6:n-3 ratios were associated with progressively elevated TNF-alpha and IL-6 levels as depressive symptoms increased. Higher levels of sIL-6r were associated with higher n-6:n-3 ratios. Six individuals who met the criteria for major depressive disorder had higher n-6:n-3 ratios and TNF-alpha, IL-6, and sIL-6r levels than those who did not meet the criteria; excluding these six individuals reduced the variance explained by the depressive symptoms and n-6:n-3 ratio interaction. CONCLUSIONS Diets with high n-6:n-3 PUFA ratios may enhance the risk for both depression and inflammatory diseases.

Abstract
The purpose of this study was to evaluate a woman's psychological and immunological response to breast biopsy before and after the procedure. Women were enrolled into the study when notified of the need for breast biopsy. Psychological and immunological assessments were made at enrollment, on the day of breast biopsy, as well as 1 month and 4 months after notification of biopsy results. Psychological assessments demonstrated that perceived stress, anxiety, and mood disturbance were heightened before biopsy and remained elevated after biopsy regardless of the diagnosis. Immunologically, the women exhibited reduced natural killer cell activity and INF gamma production before biopsy with reductions significant 1 month after the procedure. In contrast, IL-4, IL-6, and IL-10 production were increased before and after the procedure with most significant increases prior to the procedure and continuing 1 month after the procedure. These results demonstrate that undergoing biopsy of the breast for cancer diagnosis is an emotional experience, characterized by increased perceived stress, anxiety, and mood disturbance. This emotional distress is accompanied by reduced NK cell activity and cytokine dysregulation. The psychological and immunological impact of breast biopsy is not transient, but persists well beyond the actual experience of the biopsy procedure. Noteworthy is the observation that women with benign or malignant biopsy results experienced similar psycho-immune consequences. Hence, these observations are of relevance not only to women diagnosed with malignancy, who face the challenges of cancer treatment and adaptation to illness, but also to women with benign biopsy findings.

Abstract
This study investigated nuclear factor-kappa B (NF-kappaB) activity by electrophoresis mobility gel shift assay and IkappaBalpha expression by Western blot analysis in monocytes obtained from serial samples of internal jugular venous blood taken from seven migraine patients without aura during attacks. Inducible nitric oxide synthase (iNOS) expression was also assessed by reverse transcription-polymerase chain reaction. An increase in NF-kappaB activity peaked 2 h after attack onset. This was accompanied by a transient reduction in IkappaBalpha expression. Up-regulation of iNOS was evident at 4 h, maintained at 6 h and reduced at the end of the attack. These findings substantiate the hypothesis of transitory delayed inflammation, as suggested by the animal model, and suggest the possibility of using therapeutic approaches to target NF-kappaB transcription in the treatment of migraine.

Abstract
STUDY DESIGN This study was an exploratory repeated measures design comparing patients undergoing two magnitudes of surgery in the lumbar spine: lumbar herniated disc repair and posterior lumbar fusion. OBJECTIVE The present study evaluated and compared the effect of perceived pain, perceived stress, anxiety, and mood on natural killer cell activity (NKCA) and IL-6 production among adult patients undergoing lumbar surgery. SUMMARY OF BACKGROUND DATA Presurgical stress and anxiety can lead to detrimental patient outcomes after surgery, such as increased infection rates. It has been hypothesized that such outcomes are due to stress-immune alterations, which may be further exacerbated by the extent of surgery. However, psychologic stress, anxiety, and mood have not been previously characterized in patients undergoing spinal surgery. METHODS Pain, stress, anxiety, and mood were measured using self-report instruments at T1 (1 week before surgery), T2 (the day of surgery), T3 (the day after surgery), and T4 (6 weeks after surgery). Blood (30 mL) was collected for immune assessments at each time point. RESULTS Pain, stress, anxiety, and mood state were elevated at baseline in both surgical groups and were associated with significant reduction in NKCA compared with the nonsurgical control group. A further decrease in NKCA was observed 24 hours after surgery in both surgical groups with a significant rise in stimulated IL-6 production, regardless of the magnitude of surgery. In the recovery period, NKCA increased to or above baseline values, which correlated with decreased levels of reported pain, perceived stress, anxiety, and mood state. CONCLUSIONS This study demonstrated that patients undergoing elective spinal surgery are highly stressed and anxious, regardless of the magnitude of surgery and that such psychologic factors may mediate a reduction in NKCA.

Abstract
Glucocorticoids (GCs), the adrenal steroid hormones released during stress, have well-known anti-inflammatory actions. Despite that, there is increasing evidence that GCs are not uniformly anti-inflammatory in the injured nervous system and, in fact, can be pro-inflammatory. The present report continues this theme. Primary hippocampal cultures were treated with GC concentrations approximating basal, acute (1 h) stress or chronic (24 h) stress conditions and were then exposed to the excitotoxin kainic acid (KA). KA induced expression of the pro-inflammatory cytokines IL-1 beta and TNF-alpha, and chronic high dose GC exposure excacerbated this induction. In a second study, cultures were exposed to the physiological range of GC concentrations for 24 h prior to KA treatment. Low- to mid-range GC concentrations were anti-inflammatory, decreasing expression of IL-1 beta and TNF-alpha, while the highest GC doses either failed to be anti-inflammatory or even potentiated expression further. These findings add to the growing picture of these classically anti-inflammatory hormones potentially having pro-inflammatory effects in the injured CNS.

Abstract
The present report meta-analyzes more than 300 empirical articles describing a relationship between psychological stress and parameters of the immune system in human participants. Acute stressors (lasting minutes) were associated with potentially adaptive upregulation of some parameters of natural immunity and downregulation of some functions of specific immunity. Brief naturalistic stressors (such as exams) tended to suppress cellular immunity while preserving humoral immunity. Chronic stressors were associated with suppression of both cellular and humoral measures. Effects of event sequences varied according to the kind of event (trauma vs. loss). Subjective reports of stress generally did not associate with immune change. In some cases, physical vulnerability as a function of age or disease also increased vulnerability to immune change during stressors.

Abstract
OBJECTIVES Women with breast cancer are at risk for elevated depression, anxiety, and decreased natural killer (NK) cell number. Stress has been linked to increased tumor development by decreasing NK cell activity. The objectives of this study included examining massage therapy for women with breast cancer for (1) improving mood and biological measures associated with mood enhancement (serotonin, dopamine), (2) reducing stress and stress hormone levels, and (3) boosting immune measures. METHODS Thirty-four women (M age=53) diagnosed with Stage 1 or 2 breast cancer were randomly assigned postsurgery to a massage therapy group (to receive 30-min massages three times per week for 5 weeks) or a control group. The massage consisted of stroking, squeezing, and stretching techniques to the head, arms, legs/feet, and back. On the first and last day of the study, the women were assessed on (1) immediate effects measures of anxiety, depressed mood, and vigor and (2) longer term effects on depression, anxiety and hostility, functioning, body image, and avoidant versus intrusive coping style, in addition to urinary catecholamines (norepinephrine, epinephrine, and dopamine) and serotonin levels. A subset of 27 women (n=15 massage) had blood drawn to assay immune measures. RESULTS The immediate massage therapy effects included reduced anxiety, depressed mood, and anger. The longer term massage effects included reduced depression and hostility and increased urinary dopamine, serotonin values, NK cell number, and lymphocytes. CONCLUSIONS Women with Stage 1 and 2 breast cancer may benefit from thrice-weekly massage therapy for reducing depressed mood, anxiety, and anger and for enhancing dopamine, serotonin, and NK cell number and lymphocytes.

Abstract
The present report meta-analyzes more than 300 empirical articles describing a relationship between psychological stress and parameters of the immune system in human participants. Acute stressors (lasting minutes) were associated with potentially adaptive upregulation of some parameters of natural immunity and downregulation of some functions of specific immunity. Brief naturalistic stressors (such as exams) tended to suppress cellular immunity while preserving humoral immunity. Chronic stressors were associated with suppression of both cellular and humoral measures. Effects of event sequences varied according to the kind of event (trauma vs. loss). Subjective reports of stress generally did not associate with immune change. In some cases, physical vulnerability as a function of age or disease also increased vulnerability to immune change during stressors.

Abstract
To identify signaling pathways by which the sympathetic nervous system (SNS) might alter gene expression in the immune system, we assayed activation of the inflammatory transcription factor NF-kappaB in peripheral blood mononuclear cells (PBMC) from 13 healthy young adults at rest and following 5 min of intense exercise. SNS activation was verified by changes in cardiovascular parameters and mobilization of NK cells into circulating blood. Electrophoretic mobility shift assays (EMSA) of nuclear protein extracts confirmed previous findings that SNS activation increased NF-kappaB DNA-binding activity in bulk PBMC. However, analyses of isolated leukocyte subsets failed to indicate any increase on a per-cell basis in NK cells (the major carriers of NF-kappaB activity in circulating PBMC), in the residual CD56- leukocyte pool, or in CD14+ monocytes. Regression analyses indicated a strong correlation between increasing NK cell prevalence and changes in NF-kappaB DNA-binding activity in bulk PBMC, and suggested that no change in EMSA activity would be observed in the absence of NK cell mobilization. Such results imply that SNS-induced mobilization of NK cells can rapidly (< 10 min) alter NF-kappaB DNA-binding activity in the circulating PBMC pool without generating any true change in NF-kappaB activity on a per-cell basis. Implications for future efforts to analyze stress effects on leukocyte gene expression are considered.

Abstract
The aim of this study was to explore a potential link between psychosocial stress and cocaine dependence among 36 non-treatment-seeking individuals enrolled in a brain imaging protocol. Stress was assessed using computerized multidimensional instruments, including the Profile of Mood States (POMS) and Speilberger State-Trait Anxiety Inventory (STAI). Additional clinical assessments employed were the Addiction Severity Index and the Hamilton Rating Scale for Depression (HRSD). Based on the median POMS' tension-anxiety scale score the entire sample was divided into two groups, those with high and low levels of stress. The two groups (n = 16 and 20) were similar in terms of age, gender distribution, and severity of addiction. Compared with the low stress group, high-stress individuals displayed significantly longer duration of cocaine use, greater POMS, STAI-state, STAI-Trait, and HRSD scores. Our results replicate those of prior reports implicating stress in the course of cocaine dependence and extend these prior findings by 1) including a new subject population of non-treatment-seekers and 2) by suggesting that the stress-cocaine link may be generalizable to psychosocial stress and negative affective states defined by POMS, STAI, and HRSD scores.

Abstract
Little is known about the mechanisms converting psychosocial stress into cellular dysfunction. Various genes, up-regulated in atherosclerosis but also by psychosocial stress, are controlled by the transcription factor nuclear factor kappaB (NF-kappaB). Therefore, NF-kappaB is a good candidate to convert psychosocial stress into cellular activation. Volunteers were subjected to a brief laboratory stress test and NF-kappaB activity was determined in peripheral blood mononuclear cells (PBMC), as a window into the body and because PBMC play a role in diseases such as atherosclerosis. In 17 of 19 volunteers, NF-kappaB was rapidly induced during stress exposure, in parallel with elevated levels of catecholamines and cortisol, and returned to basal levels within 60 min. To model this response, mice transgenic for a strictly NF-kappaB-controlled beta-globin transgene were stressed by immobilization. Immobilization resulted in increased beta-globin expression, which could be reduced in the presence of the alpha1-adrenergic inhibitor prazosin. To define the role of adrenergic stimulation in the up-regulation of NF-kappaB, THP-1 cells were induced with physiological amounts of catecholamines for 10 min. Only noradrenaline resulted in a dose- and time-dependent induction of NF-kappaB and NF-kappaB-dependent gene expression, which depended on pertussis-toxin-sensitive G protein-mediated phosphophatidylinositol 3-kinase, Ras/Raf, and mitogen-activated protein kinase activation. Induction was reduced by alpha(1)- and beta-adrenergic inhibitors. Thus, noradrenaline-dependent adrenergic stimulation results in activation of NF-kappaB in vitro and in vivo. Activation of NF-kappaB represents a downstream effector for the neuroendocrine response to stressful psychosocial events and links changes in the activity of the neuroendocrine axis to the cellular response.

Abstract
Combinations of environmental stress coordinately increase toxicological assaults on health, dependent on the genetics of the exposed organism. Multiple gene variances between individuals influence the risks associated with environmental exposures, and environmental stress presents in multiple forms including chemical, physical, and psychological stresses. Combined chemical, physical, and psychological stresses are suggested as exacerbating the initiation and/or duration of illnesses, and many of the detrimental outcomes on health are posited to relate to changes in neuroendocrine immune circuitry. However, most human epidemiological or experimental animal studies have not considered the combination of chemical, physical, and psychological stress on health status. Current consideration is being given to "real world" exposures for assessment of health risk, but this mainly relates to evaluation of chemical mixtures. In addition to concomitant chemical exposures having agonistic and/or antagonistic interactions, the physical and psychological status of the individual can influence exposure outcomes. An individual's psychosocial environment is likely to be important in epidemiological investigations. Neuroimmunology is a burgeoning discipline, and neurotoxicology and immunotoxicology studies should consider the bidirectional regulatory mechanisms between these organ systems and the potential long-term influences of psychological stress. This mini-review discusses some intriguing data from animal and human studies, which address the regulatory pathways between the neural, endocrine, and immune systems, with emphasis on psychological stress.

Abstract
Adherence of lymphocytes to the fungus is the first step in the direct lymphocyte-mediated antifungal effect against Candida albicans. In this study we identified macrophage-1 antigen (Mac-1) (CD11b/CD18, alpha(M)/beta(2)) as the lymphocyte surface structure responsible for the adhesion of activated lymphocytes to the hyphal form of the fungus. Antibodies specific for epitopes of the alpha-subunit (CD11b) and the beta(2)-subunit (CD18) of Mac-1 were shown to completely eliminate lymphocyte adhesion to C. albicans hyphae. Lymphocyte adhesion to C. albicans was also inhibited significantly by known ligands of Mac-1, including the extracellular matrix proteins laminin and fibrinogen, as well as engineered peptides containing arginine-glycine-aspartic acid sequences and the disintegrin echistatin. N-Acetyl-D-glucosamine and beta-glucan, which inhibit Mac-1-mediated adhesion to the yeast, blocked lymphocyte adhesion to hyphae. NIH 3T3 fibroblast transfectants expressing human CD11b/CD18 bound to C. albicans, and their binding was inhibited by antibodies specific for CD11b/CD18. Finally, antibodies specific for CD11b/CD18 effectively inhibited the capacity of activated lymphocytes to have an antifungal effect against hyphae. Our results clearly identify Mac-1 (CD11b/CD18) as the lymphocyte surface structure that mediates activated lymphocyte adhesion to C. albicans and the resultant antifungal effect of the lymphocytes.
