OBJECTIVE Interleukin-2, traditionally viewed as solely involved in immunological events, has recently been shown to exert profound effects on the development and regulation of the central nervous system. This study examined the relationships between interleukin-2 in the CSF and plasma of schizophrenic patients and clinical measures, including relapse and(More)
Long-term S-antigen (S-Ag)-specific T lymphocyte lines were derived from the lymph nodes of immunized Lewis rats that had been pretreated with low-dose cyclophosphamide. The protocol consisted of functional selection by alternating cycles of stimulation with S-Ag presented on syngeneic accessory cells and proliferation in IL 2-containing spleen-conditioned(More)
We evaluated if the effects of acute stress on immune parameters were apparent in only the women who showed concomitant and substantial sympathetic nervous system activation and after statistical adjustment for changes in plasma volume. Nineteen women in the follicular stage of their menstrual cycles were assessed for immunological responsiveness to a(More)
This paper reviews evidence indicating that adrenal corticosteroids modulate the responsiveness of mice and rats to nicotine. Adrenalectomy increases, and both acute and chronic corticosteroid administration decrease, some of the physiological and behavioral effects of nicotine. One function of adrenal steroids may be to regulate stress-induced changes in(More)
Nineteen women in the follicular stage of their menstrual cycles were assessed for immunological responsiveness to a 50-min series of three psychological tasks which reliably elicit cardiovascular and neuroendocrine stress responses. Ten follicular-stage women not subjected to stress served as controls. Stress decreased lymphocyte responsiveness to PHA and(More)
In order to learn about the immunopathogenic mechanisms of experimental autoimmune uveoretinitis (EAU), the capacity of lymphocytes to transfer the disease was studied. EAU was transferred to naive syngeneic rats by intraperitoneal injection of spleen or lymph node (LN) cells from S-antigen immunized rats, following their incubation in culture with either(More)
The dynamic changes of the lymphocyte subsets in the inflamed ocular tissue in Lewis rats with experimental autoimmune uveitis (EAU) were studied by immunohistopathological evaluation at varying intervals after initiation of the disease. Monoclonal antibodies to specific markers of the rat T-helper/inducer lymphocyte (W3/25) and T-suppressor/cytotoxic(More)
To analyze the role of the retinal vascular endothelial cells in the development of experimental autoimmune uveitis (EAU), we studied the presence of Ia antigen and FN in retinal vessels of Lewis rats immunized with retinal S antigen. Immunopathologic studies were performed on frozen tissues obtained during various stages of the disease. Our results show(More)
Retinal-specific antigens can induce autoimmune diseases in eyes of immunized experimental animals and are thought to be involved in certain uveitic conditions in man. We have recently found that peripheral blood lymphocytes from a large proportion of healthy donors react in culture against the retinal S-antigen (S-Ag), when tested by a modified sensitive(More)
Experimental autoimmune uveoretinitis (EAU), an intraocular inflammatory disease, is induced in experimental animals by immunization with a retinal specific antigen, S-antigen (S-Ag), emulsified in complete Freund's adjuvant (CFA). The induction of EAU is enhanced by treating S-Ag-immunized animals with Bordetella pertussis. This study examined the effects(More)
