The study showed that in breast cancer, the activity of the local immune response in the lymph nodes is aimed at antitumor protection. In breast cancer, the area of the paracortical zone remains at the level of the intact group, the area of lymphoid nodules with germinative centers and the area of medullary substance are increased, the number of macrophages in the thymus-dependent zone and zone responsible for humoral immunity is increased. In breast cancer positive correlation were revealed: in the germinative centers and medullary substance – mitotically dividing cells with cytokine IL-5, medium lymphocytes with chemokine MIP-1О±, in the germinative centers – immunoblasts with cytokine GRO/KC, in the paracortical zone – chemokine MCP-1 with macrophages, reticular cells with IL-6 and M-CSF, in medullary substance – small lymphocytes and mature cells plasma cells (the number of which is decrease) with chemokine Gro/KC, that can be caused by their migration from lymph nodes.В

The correlation of interferon IFNОі with small lymphocytes (the number which increased) and macrophages in germinative centers and mitotic dividing cells in medullary substance, correlation in germinative centers of immunoblasts with MIP-1О± and increase of number small lymphocytes in the thymus dependent zone of lymph nodes, correlation in medullary substance of interleukin IL-17 with mature plasma cells (the number of which is increased), correlation of interleukin IL-18 with mature plasma cells in the medullary sinuses.

CYTOKINES – MARKERS OF ONCOGENESIS AND THERAPY EFFICIENCY IN CHEMICALLY INDUCED BREAST CANCER

Poster (download) Alexandr Poveshchenko11Research Institute of Clinical andExperimental Lymphology – Branch of the Institute of Cytology and Genetics,Siberian Branch of the Russian Academy of Sciences Novosibirsk, Russia, poveshchenkoa200@mail.ru Breast cancer was induced by the administration of n-methyl-N-nitrosourea to Wistar rats. Some animals underwent only surgical intervention or only polychemotherapy (cyclophosphamide, methotrexate, 5-ftorouracil). In some animals, both types of therapy were combined, and in a separate group, the administration of the Panagen drug, which was a fragmented DNA molecule, was added to polychemotherapy. To study the concentration of cytokines in lymph, we used the Bio-Plex Pro Rat Cytokoness 24-Plex Assay test system (Bio-Rad, USA). It was shown that in rats with breast cancer the content in the lymph and blood of most of the studied cytokines such as IL-1ОІ, IL-2, IL-4, IL-6, IL-7, IL-12, IL-13, MIP-1О±, MIP-3О±, RANTES, TNF-О±, MCP-1 were statistically significantly higher, and IL-10 and GRO / KC, lower than in intact animals. Surgical removal of the tumor led to a significant decrease in the content of both pro-inflammatory and anti-inflammatory cytokines in the lymph. PCT led to a significant decrease in the content of IL-1ОІ, IL-4, IL-6, IL-7, MIP-1О±, MIP-3О±, RANTES in the blood serum and lymph of rats with breast cancer.

Proteins and Cytokines of Blood Cells Supernatant and Histological Atypical Cells Markers in the Breast Diseases

In addition, he studies the correlation between concentrations of proteins and cytokines and histological markers of atypical cells. It was found that the concentration of histidine-rich glycoprotein in supernatants of blood cells with a special type of invasive carcinoma is higher compared with benign breast diseases. In addition, the following statistical relationships were observed in the study: negative correlation between estrogen receptor-α concentrations and integrin-1 expression; a positive correlation between the concentrations of histidine-rich glycoprotein and expression of type II collagen; a positive correlation between e-cadherin concentrations and e-cadherin expression; and a positive correlation between the concentrations of plasminogen-1 activator inhibitor and the expression of type II collagen. The production of cytokines by blood cells is identified as an index of the influence of polyclonal activators (a combination of mitogens). The study shows the difference in the index of influence on the production of IL-1RA and TNF-α between benign breast diseases with a high and low risk of malignant transformation and between benign breast diseases with a high risk of malignant transformation and breast cancer with metastases to the lymph nodes. The index of the effect of polyclonal activators on IL-1RA production increases as the prognosis of the disease worsens. As blood samples and tumors show, patients with benign breast diseases have a negative correlation between the index of influence of polyclonal activators on IL-1RA production and expression of type II collagen. In addition, patients with breast cancer as well as breast cancer with metastases in the lymph nodes have a positive correlation between the expression of e-cadherin and spontaneous and polyclonal stimulation stimulated by the production of IL-1RA. The results of the study showed that the concentrations of histidine-rich glycoprotein and IL-1RA in blood cell supernatants and the […]
