Abstract
Stress in patients and pre-clinical research animals plays a critical role in disease progression Activation of the sympathetic nervous system (SNS) by stress results in secretion of the catecholamines epinephrine (Epi) and norepinephrine (NE) from the adrenal gland and sympathetic nerve endings. Adrenergic receptors for catecholamines are present on immune cells and their activity is affected by stress and the accompanying changes in levels of these neurotransmitters. In this short review, we discuss how this adrenergic stress impacts two categories of immune responses, infections and autoimmune diseases. Catecholamines signal primarily through the β2-adrenergic receptors present on innate and adaptive immune cells which are critical in responding to infections caused by pathogens. In general, this adrenergic input, particularly chronic stimulation, suppresses lymphocytes and allows infections to progress. On the other hand, insufficient adrenergic control of immune responses allows progression of several autoimmune diseases.

Abstract
Analysis of a genome-scale RNA interference screen of host factors affecting herpes simplex virus type 1 (HSV-1) revealed that the mineralocorticoid receptor (MR) inhibits HSV-1 replication. As a ligand-activated transcription factor the MR regulates sodium transport and blood pressure in the kidney in response to aldosterone, but roles have recently been elucidated for the MR in other cellular processes. Here, we show that the MR and other members of the mineralocorticoid signalling pathway including HSP90 and FKBP4, possess anti-viral activity against HSV-1 independent of their effect on sodium transport, as shown by sodium channel inhibitors. Expression of the MR is upregulated upon infection in an interferon (IFN) and viral transcriptional activator VP16-dependent fashion. Furthermore, the MR and VP16, together with the cellular co-activator Oct-1, transactivate the hormone response element (HRE) present in the MR promoter and those of its transcriptional targets. As the MR induces IFN expression, our data suggests the MR is involved in a positive feedback loop that controls HSV-1 infection.

Abstract
Objective: In order to identify genetic variants associated with vestibular neuritis, a common cause of peripheral vertigo with a potential causative link to the reactivation of herpes simplex type 1 (HSV-1), we conducted a genome-wide association study. Methods: Association was assessed using approximately 8 million variants. 131 patients with vestibular neuritis and 2,609 controls of European ancestry were included. Results: Genome-wide associations with vestibular neuritis were detected in 4 regions containing protein coding genes assignable to two functional groups: virus hypothesis and insulin metabolism. Genes of set 1 are related to viral processes: nuclear receptor subfamily 3 group C member 2 (NR3C2) is a receptor for mineralocorticoids and glucocorticoids and was shown to be a host factor for HSV-1 replication. Ankyrin repeat domain 30A (ANKRD30A) encodes a host factor for human immunodeficiency virus-1 (HIV-1) infection. It shows rapid evolution and is induced by interferon stimulation. Mediator complex 30 (MED30), an important member of the mediator complex, has been shown to be involved in replication of HIV-1, a knockdown leading to impaired viral replication. The second set of genes LIM homeobox transcription factor 1 alpha (LMX1A), solute carrier family 30 member 8 (SLC30A8) is associated with insulin metabolism and resistance, a feature of some patients in whom type 2 diabetes is an accompanying comorbidity of vestibular neuritis. Conclusions: Using a GWAS approach to evaluate the etiology of vestibular neuritis these findings provide another piece of evidence that it may be caused by a viral inflammation.

Abstract
Herpes simplex virus-1 (HSV-1) infects the majority of the world's population. These infections are often asymptomatic, but ocular HSV-1 infections cause multiple pathologies with perhaps the most destructive being herpes stromal keratitis (HSK). HSK lesions, which are immunoinflammatory in nature, can recur throughout life and often cause progressive corneal scaring resulting in visual impairment. Current treatment involves broad local immunosuppression with topical steroids along with antiviral coverage. Unfortunately, the immunopathologic mechanisms defined in animal models of HSK have not yet translated into improved therapy. Herein, we review the clinical epidemiology and pathology of the disease and summarize the large amount of basic research regarding the immunopathology of HSK. We examine the role of the innate and adaptive immune system in the clearance of virus and the destruction of the normal corneal architecture that is typical of HSK. Our goal is to define current knowledge of the pathogenic mechanisms and recurrent nature of HSK and identify areas that require further study.

Abstract
The systemic elevation of psychological stress-induced glucocorticoids strongly suppresses CD8(+) T cell immune responses resulting in diminished antiviral immunity. However, the specific cellular targets of stress/glucocorticoids, the timing of exposure, the chronology of immunological events, and the underlying mechanisms of this impairment are incompletely understood. In this study, we address each of these questions in the context of a murine cutaneous HSV infection. We show that exposure to stress or corticosterone in only the earliest stages of an HSV-1 infection is sufficient to suppress, in a glucocorticoid receptor-dependent manner, the subsequent antiviral immune response after stress/corticosterone has been terminated. This suppression resulted in early onset and delayed resolution of herpetic lesions, reduced viral clearance at the site of infection and draining popliteal lymph nodes (PLNs), and impaired functions of HSV-specific CD8(+) T cells in PLNs, including granzyme B and IFN-gamma production and the ability to degranulate. In knockout mice lacking glucocorticoid receptors only in T cells, we show that these impaired CD8(+) T cell functions are not due to direct effects of stress/corticosterone on the T cells, but the ability of PLN-derived dendritic cells to prime HSV-1-specific CD8(+) T cells is functionally impaired. These findings highlight the susceptibility of critical early events in the generation of an antiviral immune response to neuroendocrine modulation and implicate dendritic cells as targets of stress/glucocorticoids in vivo. These findings also provide insight into the mechanisms by which the clinical use of glucocorticoids contributes to altered immune responses in patients with viral infections or tumors.

Abstract
Although the sympathetic nervous system innervates the lung, little is known about its participation in host immunity to pulmonary pathogens. In this study, we show that peripheral sympathectomy reduces mouse morbidity and mortality from influenza A virus-induced pneumonia due to reduced inflammatory influx of monocytes, neutrophils, and NK cells. Mortality was also delayed by treating mice with an alpha-adrenergic antagonist. Sympathectomy diminished the immediate innate cytokine responses, particularly IL-1, which was profoundly reduced. These findings demonstrate an unexpected role for the sympathetic nervous system in innate antiviral immunity and in exacerbating the pathology of a virus of great significance to human and animal health.

Abstract
CD4(+)FoxP3(+) Tregs are essential mediators of the peripheral immune response to self-antigens. Accordingly, the homeostatic regulation of Treg activity and number would impact on the immune response to both self- and non-self antigens. Because the sympathetic nervous system (SNS) interacts chemically and physically with the central and peripheral immune system and exerts a direct influence on antigen-presenting cells and effector lymphocytes, we have investigated the effect of chemical ablation of the SNS on the number and function of peripheral Treg. Removal of murine peripheral sympathetic innervation by 6-hydroxydopamine induced an increase in splenic and lymph node CD4(+)FoxP3(+) Tregs by a TGF-beta-dependent mechanism. Further, this increase in Tregs coincides with an inhibition of the induction of experimental autoimmune encephalomyelitis. Our results demonstrate that the SNS is an important contributor to the maintenance of peripheral Treg and TGF-beta acts as a bridge between the immune system and the nervous system. Neurological events mediated by the SNS, such as a stress response, may affect the number of T cells that regulate an immune response. Additionally, targeting Tregs via the SNS may be a novel approach to the prevention or treatment of autoimmune diseases.

Abstract
Psychological stress and its associated increases in corticosterone are generally immunosuppressive and contribute to increased herpes simplex virus (HSV)-associated pathogenicity. However, the impact of stress on local control of the initial mucosal-based HSV infection has not been elucidated, nor have the ramifications of such failures of the immune response in terms of viral spread. To address these gaps in knowledge, the studies described herein sought to determine how psychological stress and associated increases in corticosterone may increase susceptibility to HSV encephalitis by allowing for increased viral titers at the site of initial infection. We have shown that in mice intranasally infected with HSV-1, a cell-mediated immune response occurs in the nasopharyngeal-associated lymphoid tissue (NALT), mediastinal lymph nodes (MLN), and superficial cervical lymph nodes (CLN). However, psychological stress induced by restraint decreased the number of lymphocytes in these tissues in HSV-infected mice. Surprisingly, the effects of this restraint stress on HSV-specific CTL function varied by immune tissue. Increased viral titers were found in the nasal cavity of stressed mice, an observation which correlated with an increased CD8+ cell response in the CLN. These findings led us to extend our studies to also determine the ramifications of decreased numbers of locally derived lymphocytes on viral titers following infection. Using an approach in which the NALT was surgically removed prior to infection, we confirmed that decreased numbers of NALT-derived lymphocytes at the time of infection allows for increased viral replication. We conclude that the increased viral titers observed in mice experiencing psychological stress are the consequence of a glucocorticoid-mediated reduction in the numbers of lymphocytes responsible for resolving the initial infection.

Abstract
The cornea is one of the most highly innervated tissues in the mammalian host. We hypothesized changes to cornea innervation through chemical sympathectomy would significantly alter the host response to the neurotropic viral pathogen, herpes simplex virus type 1 (HSV-1) following ocular infection. Mice treated with 6-hydroxydopamine hydrobromide displayed reduced tyrosine hydroxylase-positive fibers residing in the cornea. Sympathectomized mice were also found to show a transient rise in virus recovered in infected tissues and succumbed to infection in greater numbers. Whereas there were no differences in infiltrating leukocyte populations including HSV-1-specific cytotoxic T lymphocytes in the infected tissue, an increase in substance P and a decrease in IFN-gamma levels in the trigeminal ganglion but not brain stem of sympathectomized mice were noted. Sympathectomized mice treated with the neurokinin-1 receptor antagonist L703,606 had delayed mortality implicating the involvement of substance P in HSV-1-mediated death.

Abstract
The neonate's immune system is relatively immature. For short-term protection against pathogens the neonate is reliant primarily on maternally derived antibodies delivered via the mother's milk. However, neonates soon acquire the ability to generate adaptive immune responses for long-term protection. Products of the nervous and endocrine systems that are elicited by psychological stress are known to modulate a variety of immune responses. Additionally, psychological stressors are well recognized for their ability to increase corticosterone levels. The studies described herein examined the effects of increases in maternally derived corticosterone on the neonatal cell-mediated immune response to, and pathogenicity of, herpes simplex virus (HSV) infection. Water containing corticosterone was made available to nursing mothers for a period of 6 consecutive days beginning on either the day of or 6 days post-delivery. At 12 days of age, neonates were infected with HSV-1 in the rear footpads. These neonates exhibited a decrease in the proliferative ability of splenic-derived cells due to the reduction of IL-2 production and IL-2 receptor alpha subunit (IL-2R alpha) expression by these cells. These neonates also exhibited a decrease in the number and function of popliteal lymph node-resident HSV-1 gB(498-505) peptide-specific CD8(+) T cells as measured by tetramer analysis, CTL lytic activity, expression of CD107a, cytokine production, and proliferation. Additionally, these HSV-infected neonates exhibited increased morbidity and mortality. Together, these studies indicate that exposure of neonates to maternally derived corticosterone via the milk hinders their ability to generate an adaptive cell-mediated immune response to a viral infection and illustrate the potential importance of maternal stress in neonatal resistance to infectious pathogens.

Abstract
The impact of restraint stress on the intestinal immune system, particularly on intestinal intraepithelial lymphocytes (i-IEL), has not been described in detail. Thus, the purpose of this study was to assess the effects of restraint stress, including those produced by increases in glucocorticoids and catecholamines, on the population of i-IEL. Mice were exposed to 1 or 4h restraint stress for 4 day, and the number of IEL in the mucosa of the proximal small intestine was determined by immunohistochemistry. The effects of restraint were also analyzed in mice submitted to different procedures: adrenalectomy, chemical sympathectomy, and treatment with a glucocorticoid antagonist (RU486), dexamethasone, and epinephrine. The main findings were that: (1) chronic restraint-stress reduced the i-IEl population in the small intestine; (2) adrenalectomy, treatment with RU-486 and chemical sympathectomy decreased the number of gammadelta, CD4+ and CD8+ T cells in non-stressed groups; (3) dexamethasone reduced the number of gammadelta and CD8+ T cells, and (4) epinephrine reduced the number of gammadelta, CD4+ and CD8+ T cells. These results demonstrated that restraint stress decreased the number of i-IEL in the proximal small intestine of mice, mainly by the combined action of higher concentrations of catecholamines and glucocorticoids, and that lower concentrations of glucocorticoids and catecholamines in unstressed mice preserved the population of i-IEL.

Abstract
Recurrent HSV-1 ocular disease results from reactivation of latent virus in trigeminal ganglia, often following immunosuppression or exposure to a variety of psychological or physical stressors. HSV-specific CD8+ T cells can block HSV-1 reactivation from latency in ex vivo trigeminal ganglia cultures through production of IFN-gamma. In this study, we establish that either CD8+ T cell depletion or exposure to restraint stress permit HSV-1 to transiently escape from latency in vivo. Restraint stress caused a reduction of TG-resident HSV-specific CD8+ T cells and a functional compromise of those cells that survive. Together, these effects of stress resulted in an approximate 65% reduction of cells capable of producing IFN-gamma in response to reactivating virus. Our findings demonstrate persistent in vivo regulation of latent HSV-1 by CD8+ T cells, and strongly support the concept that stress induces HSV-1 reactivation from latency at least in part by compromising CD8+ T cell surveillance of latently infected neurons.

Abstract
The effects of restraint stress on the intestinal humoral immune system, particularly those about intestinal IgA production, have not been explored in detail. Thus, the purpose of this study was to assess the effect of restraint stress on the production and secretion of intestinal IgA as well as on the number of IgA+ cells in the intestinal lamina propria. The involvement of glucocorticoids and catecholamines were also evaluated. Mice were exposed to 1 or 4 h restraint stress for 4 d. The intestinal IgA concentration was quantified by ELISA and the number of IgA containing cells in the lamina propria was determined by immunohistochemistry. The effects of restraint were also analyzed in mice submitted to different procedures: adrenalectomy, chemical sympathectomy, treatment with a glucocorticoid antagonist (RU486), dexamethasone and epinephrine. The main findings were that (1) chronic restraint-stress reduced the intestinal IgA concentration without changing the number of IgA+ cells in lamina propria; (2) adrenalectomy restored the production of IgA in stressed mice; (3) RU486 and chemical sympathectomy partially blocked the decrease in intestinal IgA in stressed mice; and (4) pharmacological doses of dexamethasone and epinephrine significantly reduced the intestinal IgA concentration and the number of IgA+ cells. The restraint stress probably reduced the intestinal IgA concentration through the effects of glucocorticoids and catecholamines.

Abstract
Cold restraint (CR) for 1 h elicits a psychological and physiological stress that inhibits host defenses against Listeria monocytogenes (LM). Previous analyses indicated that this inhibition is not due to depletion of B or T cells but is instead dependent on signaling through beta-adrenoceptors (betaARs). We now show that impaired host resistance by CR cannot be accounted for by a decrease in LM-specific (listeriolysin O(91-99) tetramer(+)) effector CD8(+) T cells; this result is consistent with previous observations that CR-induced effects are mainly limited to early anti-LM responses. beta2-Adrenoceptor (beta2AR)(-/-) FVB/NJ and wild-type FVB/NJ mice had equivalent anti-LM defenses, whereas beta1-adrenoceptor (beta1AR)(-/-) FVB/NJ mice had lower levels of LM even when subjected to CR treatment. Additionally, host-resistance competency of beta1AR(-/-) mice could be transferred to irradiated wild-type mice reconstituted with beta1AR(-/-) bone marrow progenitors and spleen cells, indicating that beta1AR signaling on immune cells reduces anti-LM responses. beta1AR(-/-) mice had improved cellular (delayed-type hypersensitivity) responses while beta2AR(-/-) mice had improved humoral responses (IgG1, IgG2, and IgM), a result that further explains the strain differences in LM defenses. CR-induced expression of beta1AR and beta2AR mRNA was assessed by real-time PCR. CR treatment significantly increased betaAR mRNAs in Ficoll-purified and F4/80(+)-enhanced liver but not splenic homogenates, demonstrating an organ-specific effect of stress that alters host defenses. Finally, CR treatment induced early increases in perforin expression that may enhance immune cell apoptosis and interfere with LM clearance. In conclusion, beta1AR signaling has immunomodulatory effects on early cell-mediated immune responses; a lack of beta1AR signaling improves antilisterial defenses and cell-mediated immunity, in general.

Abstract
BACKGROUND Bipolar disorder is associated with deficits in cognitive functioning. The etiology of cognitive impairment in bipolar disorder may relate to both genetic and environmental factors. A valine/methionine polymorphism of the catechol O-methyltransferase gene at amino acid 158 (COMT Val158Met polymorphism) has been identified as a risk factor for cognitive impairment in schizophrenia. Serological evidence of infection with herpes simplex virus type 1 (HSV-1) has also been identified as a risk factor for cognitive impairment in bipolar disorder. METHODS We used Taqman technology to measure COMT Val158Met alleles in 107 individuals with bipolar disorder and in 95 controls. We also measured antibodies to HSV-1 in sera obtained from the same individuals. Cognitive functioning was assessed with the Repeatable Battery for the Assessment of Neuropsychological Status and the Letter-Number Sequencing Test. The effects of the COMT Val158Met polymorphism and antibodies to HSV-1 on cognitive functioning were analyzed with multinomial logistic regressions. RESULTS The COMT Val158Val genotype and serological evidence of infection with HSV-1 are independent risk factors for cognitive impairment in individuals with bipolar disorder, particularly in the domains of immediate and delayed memory. Individuals with bipolar disorder with the COMT158 Val/Val genotype and serological evidence of HSV-1 infection were more than 85 times more likely to be in the lowest quintile of cognitive functioning when compared with the highest quintile when controlling for potential confounding variables such as symptom severity and education. Control individuals did not display this association. CONCLUSION Both the COMT Val158Met polymorphism and serological evidence of HSV-1 infection affect cognitive functioning in individuals with bipolar disorder.

Abstract
The immunosuppressive nature of glucocorticoids has been well documented both in vitro and in vivo. This glucocorticoid-mediated immunosuppression has also been observed in immune cells within the central nervous system (CNS). For example, microglia have previously been shown to exhibit decreased proliferation, cytokine production, and antigen presentation upon treatment with glucocorticoids in vitro. Despite these in vitro findings, the impact of glucocorticoids on microglia function in vivo has not been fully investigated. To determine the interaction between glucocorticoids and microglia within the CNS, we used a restraint model of psychological stress to elevate corticosterone levels in mice. Quantification of microglia from stressed mice indicated that four sessions of stress induced the proliferation of microglia. This proliferation was a function of corticosterone-induced activation of the N-methyl-D-aspartate (NMDA) receptor within the CNS since blockade of corticosterone synthesis, the glucocorticoid receptor, or the NMDA receptor each prevented stress-induced increases in microglia number. In addition, the NMDA receptor antagonist MK-801 prevented increases in microglia following exogenous corticosterone administration to non-stressed mice. We conclude that activation of the NMDA receptor and subsequent microglia proliferation is a downstream effect of elevated corticosterone levels. These findings demonstrate that elevated levels of glucocorticoids are able to activate microglia in vivo and suggest that stress is able to induce a pro-inflammatory response within the CNS. A pro-inflammatory microglia response may be a contributing factor in the development of various stress-induced inflammatory conditions in the CNS.

Glucocorticoids produced during exercise may be necessary for optimal virus-induced IL-2 and cell proliferation whereas both catecholamines and glucocorticoids may be required for adequate immune defense to viral infection. Brain Behav Immun 2005; 19:423-35.

Abstract
Prolonged, exhaustive exercise has been associated with impaired immune responsiveness and increased susceptibility to infection. We have shown that one bout of exercise to fatigue followed by viral challenge increases mortality. Stress hormones such as corticosteroids and catecholamines have been suggested as potential mediators of exhaustive exercise-induced immunosuppression. The purpose of this study was to determine whether the administration of pharmacological agents to block the effect of catecholamines or corticosteroids would minimize the immunosuppression associated with this type of exercise. Mice either exercised to fatigue or were exposed to control conditions, and mice received an i.p. injection of either nadolol (beta-adrenergic receptor antagonist), RU486 (glucocorticoid type II receptor antagonist), or vehicle. Fifteen minutes post-exercise, mice were exposed to viral infection (Herpes simplex virus; HSV) via an intranasal route, and cells were collected 3 days post-infection. The results showed that exercise suppressed HSV-specific cell proliferation, HSV-specific IL-2, and IFN-gamma, but did not alter these same immune parameters when the mitogen ConA was used to stimulate cells. In addition, exercise reduced NK cell cytotoxicity, alveolar cell TNFalpha, and peritoneal IL-1beta, but did not affect IL-10. The pharmacological blockade did not attenuate the exercise-associated immunosuppression. In fact, RU486 treatment exacerbated the exercise-induced decline in HSV-induced IL-2 production and cell proliferation. RU486 and nadolol treatment also tended to decrease IL-10, IFN-gamma, TNFalpha (nadolol only), and IL-1beta (RU486 only) in both exercise and control mice, suggesting that stress hormones may be necessary during infection for optimal responsiveness. These findings suggest that suppression of immune defenses during viral infection persists for at least 3 days post-exercise, and stress hormones may be essential for optimal immune defense to viral challenge, rather than detrimental.

Abstract
OBJECTIVE The responsiveness of the sympathetic nervous system (SNS) and the hypothalamic--pituitary--adrenal (HPA) axis plays a major role in immune regulation and for the outcome of infections and inflammatory disorders. This study was designed to investigate whether chemical SNS denervation with the noradrenaline-selective neurotoxic drug 6-hydroxydopamine (6-OHDA), which destroys peripheral noradrenaline terminals, would influence immune responses to Gram-negative bacterial lipopolysaccharide (LPS) stimulation, and the progression of ligature-induced periodontal disease in Fischer 344 rats. MATERIAL AND METHODS 6-OHDA (40--60 microg/kg) or vehicle was injected intraperitoneally (i.p.) on days 1, 3 and 5, 10 days before application of the ligatures, and thereafter weekly in doses of 80 microg/kg. Periodontal disease was assessed when the ligatures had been in place for 49 days. At 24 and 2 h before decapitation, all rats received LPS (150 microg/kg i.p.) to induce a robust immune and HPA axis response. RESULTS The 6-OHDA-treated rats showed significantly reduced bone loss as measured by digital X-rays (p< 0.01), and enhanced levels of the cytokines transforming growth factor-beta (p=0.05) and interleukin-6 (p=0.05), as well as the HPA axis derived hormone corticosterone (p=0.01), induced by LPS stimulation. CONCLUSIONS 6-OHDA-induced chemical sympathectomy inhibits ligature-induced periodontal disease in this model. This effect may be attributable to the well-documented ability of the SNS to regulate immune system function primarily via the adrenergic neurotransmitter noradrenaline released at sympathetic nerve terminals. The enhanced HPA axis activation may be a compensatory response that reduces the T helper (Th)2 to Th1 skewing effect of treatment with 6-OHDA.

Abstract
Folk wisdom has long suggested that stressful events take a toll on health. The field of psychoneuroimmunology (PNI) is now providing key mechanistic evidence about the ways in which stressors--and the negative emotions that they generate--can be translated into physiological changes. PNI researchers have used animal and human models to learn how the immune system communicates bidirectionally with the central nervous and endocrine systems and how these interactions impact on health.

Abstract
A single injection of morphine significantly increased interferon (IFN)-beta and IFN-alpha mRNA in spleens from herpes simplex virus (HSV)-1 infected male Balb/cByJ mice. However, significant suppression of IFN-gamma and interleukin (IL)-12 production was observed in spleens from morphine-treated mice. Pretreatment with RU486 blocked morphine-induced increases in IFN-beta, and reversed the suppression of IFN-gamma. However, RU486 did not restore IFN-alpha or IL-12. The results suggest that a single exposure to morphine 4 h prior to infection can significantly alter innate immune responses to a viral pathogen, and that these effects are partially mediated by glucocorticoids.

Abstract
Despite the generally restrictive nature of the blood-brain barrier (BBB), circulating lymphocytes can infiltrate into the central nervous system (CNS) during a variety of disease states. Although the contributions of these lymphocytes to CNS-associated disease have been identified in some viral models, the factors which govern this infiltration following herpes simplex virus (HSV) infection remain to be elucidated. We have developed a murine model of HSV encephalitis (HSE) to define the relationship among psychological stress, the recruitment of HSV-specific T cells into the CNS, and the development of HSE. Naive mice, as well as mice that had been vaccinated with a recombinant vaccinia virus (rVVESgB498-505) that elicits the generation of HSV-1 gB498-505-specific CD8(+) T cells, were infected intranasally (i.n.) with HSV-1 McIntyre. Beginning one day prior to HSV-1 infection and continuing for a total of 9 days, naive and vaccinated mice were exposed to a well-established stressor, restraint stress. Naive, stressed mice exhibited increased symptoms of HSE and HSE-associated mortality as compared to non-stressed controls. A concomitant increase in CD4(+) and CD8(+) T cells in the brain was observed throughout the infection, with CD8(+) T cells outnumbering CD4(+) T cells. The development of HSE in these naive, stressed mice was accompanied by a delayed infiltration of gB498-505-specific CD8(+) T cells after HSV spread into the brain. In contrast, both stressed and non-stressed rVVESgB498-505-vaccinated mice possessed gB498-505-specific CD8(+) T cells prior to HSV challenge and were protected against HSE despite having detectable HSV-1 DNA in the brain. Together, these findings suggest that a delayed infiltration of CD8(+) T cells into the brain may promote HSE in naive mice, while the presence of HSV-specific CD8(+) T cells in the brain prior to HSV challenge is protective, possibly by limiting HSV replication and spread within the CNS.
