Psycho-Neuro-Immunologie. Einfluss einer psychosozialen Intervention auf T und NK Zellfunktion von Patientinnen mit Mammakarzinom

Abstract
The autonomic, neuroendocrine, and the immune systems are orchestrated in part to preserve conditions compatible with life. The critical question in immunosurveillance against cancer is whether differences between individuals with regard to immunologic host-defense mechanisms can predict the incidende or progression of cancer. Acute as well as chronic stressors have been associated with reduction of various in vitro measures of immune function. Even acute commonplace stressful events like a final examination scenario for medical students or "the public speaking situation" are associated with transient changes in immunologic parameters (e.g. natural killer(NK) cell number and cytotoxity, T helper/inducer cell number, production of interferon (IFN) gamma by lymphocytes stimulated with Concavalin-A, etc.) along with elevated stress hormone levels and cardiovascular activation compared to controls. The aims of the study are: * Further evaluation of differences in immune parameters of patients with breast cancer compared to their significant others and non related healthy volunteers focusing on differences in the relative number of T and NK cell subpopulations, onset of apoptosis and functional parameters like the kinetics of perforin release of stimulated T and NK cells. *Assessment of hormonal parameters in the three study populations and their correlation to immune parameters as well as psychosocial parameters. * Investigation of the influence of psychosocial intervention on the immune system with special regard to T cell- and NK cell subpopulations, rate of apoptosis and perforin release of these immune cells in patients with operated breast cancer compared to significant others and healthy volunteers.
