The heterogeneity of patients meeting American College of Rheumatology (ACR) criteria for a diagnosis of fibromyalgia (FM) challenges our ability to understand the underlying pathogenesis and to optimize treatment of this enigmatic disorder. Our goal was to discern clinically relevant subgroups across multiple psychological and biomedical domains t...
Article
This study replicates and extends prior reports of abnormal cytokine levels in chronic pain patients and has correlated the alterations with pain severity. In addition, there appeared to be a need to directly assess cerebrospinal fluid (CSF) because previous findings on cytokine concentrations in peripheral circulation have been inconsistent. CSF a...
Article
Little research regarding appropriate immunization administration technique for adults has been carried out. Pain is a leading cause of self-deferral from immunizations. The purpose of this study was to determine whether administering intramuscular injections using cold needles would decrease patients' perceived pain and have an effect on the immun...

Placebos are boon and bane to medical theory and clinical practice. On the one hand, randomized controlled trials employ concealed allocations of placebo to control for effects not due to specific pharmacological mechanisms. As a result, nearly all of evidence-based medicine derives from principles and practices based on placebo. On the other hand,...

Increasingly, researchers attend to both positive and negative aspects of mental health. Such distinctions call for clarification of whether psychological well-being and ill-being comprise opposite ends of a bipolar continuum, or are best construed as separate, independent dimensions of mental health. Biology can help resolve this query--bipolarity...

Few studies have examined the potentially beneficial role of positive psychological functioning in individuals with chronic pain. This study examined the relationship of psychological well-being (PWB) to pain and disability in women with fibromyalgia (FM) as compared to women with rheumatoid arthritis (RA) and healthy controls (HC). We targeted sev...
Article
This study examined the influence of the menstrual cycle on pain and emotion in women with fibromyalgia (FM) as compared with women with rheumatoid arthritis (RA) and to healthy controls. One hundred and twenty-five premenopausal women (21-45 years old) participated in this study (57 with FM, 20 with RA, and 48 controls). Pain and emotion assessmen...
Article
Many reports of interactions between drugs metabolized by CYP3A4 and influenza vaccine have been made. The authors hypothesized that changes in CYP3A4 activity following influenza immunization would correlate with cytokine production or age. Twenty-four subjects had an erythromycin breath test (ERMBT) and blood draw for lymphocyte culture prior to...
Article
Considerable evidence exists to support an association between psychological states and immune function. However, the mechanisms by which such states are instantiated in the brain and influence the immune system are poorly understood. The present study investigated relations among physiological measures of affective style, psychological well being,...

The underlying changes in biological processes that are associated with reported changes in mental and physical health in response to meditation have not been systematically explored. We performed a randomized, controlled study on the effects on brain and immune function of a well-known and widely used 8-week clinical training program in mindfulnes...
Article
Existing data suggest that immune function is compromised by negative psychosocial factors. We hypothesized that high psychological well being and quality relationships would be associated with vigorous cytokine responses to vaccination. Lymphocytes from 18 individuals were studied for their ability to produce interferon-gamma (IFN-gamma) and inter...
Article
To assess helper T cell function by measuring cytokine production over time after hepatitis A immunization. Open-label, single-dose study. General clinical research center of a university hospital. Twenty-five healthy adults. Each subject was immunized with inactivated hepatitis A vaccine; blood was drawn on day 0 (the day of immunization) and days...
Article
Farmers are at increased risk of contracting tetanus. However, no difference in immunity to tetanus has been reported between rural and urban dwellers in large epidemiological studies. We hypothesized that tetanus antibody concentrations would be lower in farmers than in nonfarmers within the rural population. We recruited 102 adult subjects attend...
Article
Lymphocytic choriomeningitis virus (LCMV) infection of beta2-microglobulin-deficient (beta2m-/-) mice results in a substantial loss of body weight that is not mediated by the virus itself, but rather by CD4+ T cells responding to the viral infection. In this study, we further characterized LCMV-induced weight loss in immunocompetent and beta32m-/-...

Lymphocytic choriomeningitis virus (LCMV) infection of normal mice results in a fatal immunopathologic meningitis mediated by CD8+ cytotoxic T lymphocytes (CTL). We have previously shown that female beta2-microglobulin-deficient (beta2m-/-) mice, which are also deficient in CD8+ T cells, are susceptible to LCMV-induced immune-mediated meningitis, c...
Article
CD8+ T cells are the major mediators of cytotoxic T cell activity controlling viral infections in normal mice. CD8+ T cells have also been implicated in regulating the activity of other immune cells. We have examined the possible regulatory role of CD8+ T cells on CD4+ T cells by comparing immune responses in mice expressing normal CD8+ T cell resp...
Article
Intracranial (i.c.) infection of immunocompetent mice with lymphocytic choriomeningitis virus (LCMV) results in immunopathological lethal meningitis mediated by CD8+ cytotoxic T lymphocytes (CTL). Vaccination of immunocompetent mice elicits a CD8+ CTL response that can protect the mice from lethal meningitis. beta 2 microglobulin-deficient (beta 2m...
Article
Innate and acquired immune responses have evolved to protect us against external and internal pathologic processes. Tolerance evolved to limit autoimmune responses to a level we call normal autoimmunity. This article outlines our understanding of the multifactorial pathogenic factors (internal, external, and stochastic) leading to autoimmune diseas...
Article
We have investigated the induction and role of natural killer (NK) activity in lymphocytic choriomeningitis virus (LCMV)-infected β2-microglobulin-deficient (β2m−) mice. We demonstrate that LCMV infection is more effective than polyinosinic:poiycytidylic acid (poly I:C) at stimulating NK activity in β2m− .In addition, β2m− NK cells respond poorly t...
Article
Oestrogen directly influences autoimmune diseases and the immune response to microbes. We studied the effect of oestrogen on CD4+ T cells specific for lymphocytic choriomeningitis virus (LCMV) using mice genetically engineered to be deficient in beta 2-microglobulin (beta 2m-/-). These mice are deficient in beta 2-microglobulin, class I major histo...

Mice with a homologous deletion of the beta 2-microglobulin gene (beta 2m-) are deficient in class I major histocompatibility complex molecules (MHC) and consequently are deficient in CD8+ T cells. These beta 2m- mutant mice control the intraperitoneal growth of an avirulent vaccine strain of mycobacteria, Mycobacterium bovis BCG, after intraperito...
Article
We describe a flow cytometry method to simultaneously analyze IFN-gamma production and T cell surface phenotype in freshly isolated lymphocytes without requiring prior in vitro stimulation. We show that enumeration of intracytoplasmic IFN-gamma positive T cells correlates with quantitative measurement of IFN-gamma in culture supernatant fluids. Thi...
Article
In this study we have investigated the role of CD4+, MHC class II-restricted cytotoxic T lymphocytes (CTLs) in the disease caused by lymphocytic choriomeningitis virus (LCMV) in beta 2-microglobulin deficient (beta 2m-) mice. Intracranial (i.c.) infection with LCMV resulted in death of six out of 11 beta 2m- mice. Mice that survived showed a marked...
Chapter
The ability to disrupt the function of a given protein molecule is a powerful technique. This approach has been extremely useful in modern biology. Monoclonal antibodies have been used to disrupt molecular function in vitro and in vivo. In addition, synthetic antisense oligonucleotides have been useful in disrupting the function of genes at the pre...
Article
Intracranial infection of normal mice with lymphocytic choriomeningitis virus (LCMV) causes meningitis and death mediated by CD8+ major histocompatibility complex (MHC) class I-restricted cytotoxic T lymphocytes (CTLs). beta 2-Microglobulin-deficient mice (beta 2M-/-) do not express functional MHC class I proteins and do not produce significant num...
Article
Class I molecules of the MHC bind foreign and endogenous peptides allowing recognition by the TCR on CTL. The recognition and killing of cells infected with lymphocytic choriomeningitis virus (LCMV) depends on the recognition of LCMV peptides bound to class I MHC. Mutations in class I MHC molecules have enabled the delineation of regions in the cla...
Article
Our strategy to use saturation mutagenesis to produce an unbiased collection of major histocompatibility class I mutants has resulted in unpredicted mutant phenotypes. First, we have shown data supporting our earlier work of the Dp20(Y27N) mutant. Allorecognition is altered at the clonal level while no variation in lymphocytic choriomeningitis viru...
Chapter
The study of variants induced by mutagenesis has been extremely important in understanding many biological systems (Drake 1969). In the case of the mouse histocompatibility complex (MHC) H-2 mutants have been important in the definition of pleiotropic effects of single MHC genes. These mutants were laboriously isolated by screening for skin graft r...
Chapter
Mutations in the major histocompatibility complex (MHC) have been used to delineate the structure and function of these polymorphic molecules (Klein 1986). The original descriptions of these cell surface glycoproteins were concerned with their function as transplantation antigens (allorecognition). However, a more recently recognized function of th...
