Processed antigen reacts selectively with lymphocytes bearing .appropriate surface immunoglobulin molecules resulting in the clonal proliferation of these cells, produc­ing circulating immunoglobulin (humoral immunity) or non-circulating immunoglobulins (cellular immunity).  High levels of circulating immunoglobulins (lgM & lgG) occur in protozoa and helminths infections. Reaginic antibodies a...

Background detailed information about circulating tumor cells (CTCs) as an indicator of therapy response and cancer metastasis is crucial not only for basic research but also diagnostics therapeutic approaches. Here, we showcase a newly developed IsoMAG IMS system with optimized protocol fully automated immunomagnetic enrichment CTCs, revealing rare CTC subpopulations.

perivascular epithelioid cell tumor (pecoma) is composed of hmb45+ epithelioid cells with clear to granular cytoplasm and perivascular distribution. we describe a uterine pecoma in a 33 years old woman where tumor cells were positive for hmb45 but negative for epithelial markers and negative or positive for smooth muscles markers.

Lidocaine has been shown to inhibit the invasion and metastasis of breast cancer, but mechanism still remains unclear. This study explored relationship between lidocaine circulating seeding cancer cells from perspective nerve fiber formation. The cell lines MDA-MB-231 4T1 were subcutaneously inoculated in mice simulate tumor self-seeding by cells. was used treat these growth observed. Silver st...

background: alteration in peripheral blood lymphocytes (pbls) is usually investigated to provide an evidence of the host immune responses to tumor antigens. the tumor infiltrating nk cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. objective: to analyze peripheral blood and tumor associated natural killer (nk) cells in patients with breast ca...

Analysis of circulating tumor cells from patients with different types of cancer is nowadays a fascinating new tool of research and their number is proven to be useful as a prognostic factor in metastatic breast, colon and prostate cancer patients. Studies are going beyond enumeration, exploring the circulating tumor cells to better understand the mechanisms of tumorigenesis, invasion and metas...

OBJECTIVE To apply a new immunocytochemistry (ICC) assay to peripheral blood samples for micrometastatic circulating tumor cell detection in patients with head and neck squamous cell cancer (HNSCC). DESIGN The ICC assay uses established monoclonal antibodies that bind to tumor-associated antigens combined with an enrichment system that uses positive selection with anti-human epithelial antige...
