Integrins are a class of cell adhesion molecules that participate in cell-cell and cell-substratum interactions and are present on essentially all human cells. The distribution of nine different alpha and beta integrin subunits in human endometrial tissue at different stages of the menstrual cycle was determined using immunoperoxidase staining. Glandular(More)
Since tumor progression is dependent on the ability of malignant cells to interact with the extracellular matrix, molecules on the cell surface which mediate cell-substratum interactions are likely to be important regulators of tumor invasion and metastasis. The purpose of this study was to examine the distribution of one such group of cell adhesion(More)
The integrins are a family of transmembrane glycoproteins that serve as cell-cell and cell-substratum adhesion molecules and help regulate cellular morphology, differentiation, and proliferation. The integrin repertoire of a cell may therefore influence its behavior under resting conditions or following malignant transformation. For this reason, the(More)
Rapid evaporative ionization mass spectrometry (REIMS) is an emerging technique that allows near-real-time characterization of human tissue in vivo by analysis of the aerosol ("smoke") released during electrosurgical dissection. The coupling of REIMS technology with electrosurgery for tissue diagnostics is known as the intelligent knife (iKnife). This study(More)
BACKGROUND Proper preoperative staging is vital in the treatment of breast cancer patients. The aim of our study was to assess the value of the diagnostic information provided by PET/CT in surgical practice in breast cancer cases considered early-stage by conventional diagnostic modalities. METHODS Whole-body 18-FDG PET/CT was performed on 115 breast(More)
Clusters of MHCI, ICAM-1, CD44, CD59, IL-2R, and IL-15R molecules have been studied on the surface of CD4(+) T-cells from peripheral blood and lymph nodes of patients in Crohn's disease and healthy individuals as controls by using a dual-laser flow cytometric fluorescence resonance energy transfer (FRET) technique and fluorescently stained Fabs. When cells(More)
Previously, we described conserved protein clusters including MHC I and II glycoproteins, ICAM-1 adhesion molecules, and interleukin-2 and -15 receptors in lipid rafts of several human cell types. Differential protein-protein interactions can modulate function, thus influence cell fate. Therefore, we analyzed supramolecular clusters of CD4(+) T cells from(More)
INTRODUCTION Hereditary Non-polyposis Colorectal Carcinoma is the most frequent genetic disease leading to colon and other malignancies. Recognizing the condition requires extensive family history going back several generations focusing particularly on the types of tumors occurring in the family at different age groups. METHODS In families who met the(More)
The formation of protein patterns in lymphocyte plasma membranes is analyzed in the light of past and, also, very recent experiments. The analysis surveys the lateral organization of major histocompatibility complex glycoproteins, intercellular adhesion molecule-1, interleukin-2 and -15 receptors, Kv1.3 K+ ion channels and the T-cell receptor as well as(More)
A theoretical analysis of experimental data is presented in this mini-review on non-random homo- and hetero-associations of cell surface receptors, which can be recruited in the plasma membrane or at the surface of the rough endoplasmic reticulum during the protein synthesis. In the latter case, the likely genetic origin of these supramolecular formations(More)
