چکیده

Sera from breast cancer patients contained cytophilic antibody which armed guinea pig peritoneal macrophages. These macrophages then exhibited specific adherence inhibition in the presence of tissue culture tumor antigens. These antigens were obtained from primary cultures of autologous or allogeneic breast cancer cells. Sera from control subjects for the most part did not induce macrophage adherence inhibition in the presence of these same antigens.

Flowcytometric Analysis of Tumor Associated Macrophages in Invasive Ductal Carcinoma of Breast

Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis.   Objective: To analyze the status of tumor as...

Immunoelectronmicroscopic analysis of surface antigens common to Mycobacterium bovis (BCG) and tumor cells.

The presence of cell-surface antigens on line10 hepatocarcinoma cells was demonstrated by immunoelectronmicroscopy (IEM) with the use of xenogeneic and syngeneic tumor-specific antibody and syngeneic BCG-induced antibody. This confirmed that in addition to tumor-specific antigen(s) there are common antigens between line-10 hepatocarcinoma cells and BCG organisms. The specificity of this cross-r...

Possible Association of CD68 Positive Macrophages with Some other Prognostic Factors (ki67, ER, PR, Her2 neu) in Primary Breast Cancer and Axillary Lymph Node Metastasis

Background: Breast cancer is formed of a neoplastic component (epithelial) and a non-neoplastic component (stroma). Stromal- stromal and tumor- stromal interactions have been shown in the regulation of cancer cell growth, metastatic capacity and outcome of treatment. Tumor-associated macrophages (TAMs) are a component of tumor stroma reactionsand are considered as an important ...

Evaluation of [18F]FPTT Molecular structure and its binding to progesterone receptor (PR) for PET scan of breast cancer FPTT Molecular structure and its binding to progesterone receptor (PR) for PET scan of breast cancer

Breast cancer is a complicated disease that it is accompanied by different symptoms. Diagnosis of this disease is performed by various techniques. Using Radiopharmaceuticals is a new method to diagnose the said tumors. [18F]-FPTT is one of these nuclear medicines for detection of breast cancer. It seems that the binding of the title radiopharmaceutical to the progesterone receptor is...

Human autologous mixed lymphocyte reactivity is primarily specific for xenoprotein determinants adsorbed to antigen-presenting cells during rosette formation with sheep erythrocytes

We present evidence that most T cells proliferating in response to autologous sheep erythrocyte (SRBC)-separated non-T cells (NT) cells are not specific for autoantigens but for antigens derived from xenogeneic sources. The conclusion was based on the following three observations. First, we found that NT cells isolated in the absence of xenoproteins by means of density gradient centrifugation o...
