Opis:
Application of cells with high TAA (tumor associated antigen) presentation potential seems to be crucial in neoplasia immunotherapy. Such feature is distributed in dendritic cells, which present peptides from processed TAA - MHC molecules complex to the T cells of a host. The aim of the study was to assess the influence of colon neoplasia tissue lysate on functioning of generated autologous DC’s in the field of autologous CD4+ lymphocytes immunological response towards Th1/Th2 under in vitro environment together with comparison and assessment of DCs’ immunosuppressive properties acquired from patients with colon cancer. Material and methods. The population of this study consisted of 16 healthy- controls, 36colon cancer patients. Blood samples were collected 24h before planned surgery and preventive antibiotic therapy. Neoplastic tissue sample, was digested for cell lysates preparation. DC’s generation from PBMC was carried out in standard conditionsand medium enriched with rhGM-CSF and rhIL-4. Mature DC`s and cocultured autologous CD4 lymphocytes immunophenotype assessment was analyzed with flow cytometer. Intracellular and culture medium cytokines concentration was analyzed with ELISA and FACS method. Results. DC`s generated from colon cancer patients stimulated with lysates presented greater maturity, lower expression of CD206 antigen, significantly higher expression of HLA-DR, CD208 and CD209 and high intracellular expression of IL-12, compared to non-stimulated cells. Conclusions. The neoplastic tissue in vivo produces a number of substances having an unfavorable effect on immune system, our results suggests using lysates as good dendritic cells stimulators that possibly could have application in colon cancer immunotherapy

Opis:
Thrombangiitis obliterans (TAO marked by coexistence of thrombotic and inflammatory changes of neurovascular tract has evoked a considerable dispute concerning pathogenesis of this disease. The aim of the study was to define the level of activation of fibirinolitic system in course of TAO disease by means of determination its basic constituents as well as to examine the essence of level of fibrinolysis disorders in pathogenesis and development of this disease. Material and methods. Fifty patients with thrombangiitis obliterans (TAO), 30 patients with peripheral occlusive disease - PAOD (ASO) and 20 healthy volunteers (K) have been subjected to the examination. We determined the activity some factors of fibrinolysis: t-PA, PAI-1, PAP, plasminogen, α2-antiplasminogen, D-dimmer as well as euglobulin lysis time. The analysis comprised 7 features and 8 factors of variability: a membership to a group of patients, sex, age, smoking, aggravation of the disease within last 3 months, occurrence of Raynaud’s symptom, a degree of ischemia according to Fontaine, time the disease lasted. Results. The significant differences between the average were checked by means of t-Student test or variance analysis (ANOVA) and co-relation rate r (Pearson). We concluded that the average value of PAI-1 in the group TAO was significantly higher than in comparison with ASO group. The increased values were revealed in case of 76 % of patients. The euglobulin lysis time was vitally extended in case of 60% of patients in ASO group. In all three groups higher levels of α2-antiplasmin were detected in case of elderly patients compared to the younger ones. Conclusions. The obtained results allow us to ascertain the state of potentially weakened fibrinolysis in case of patients with Buerger’s disease as well as with PAOD.
