Sleep is hypothesized to have a role in the regulation of the immune system. This study evaluated the nocturnal expression of cellular adhesion molecules, Mac-1 and L-selectin on monocytes and lymphocytes during a full nights sleep and following a partial night of sleep deprivation (PSD). Healthy male subjects (n=16) had an increase in the percentage of Mac-1 positive lymphocytes across the bas...

Cell adhesion molecules of the immunoglobulin superfamily (IgSF) including the neural cell adhesion molecule (NCAM) and members of the L1 family of neuronal cell adhesion molecules play important functions in the developing nervous system by regulating formation, growth and branching of neurites, and establishment of the synaptic contacts between neurons. In the mature brain, members of IgSF re...

BACKGROUND Increased plasma levels of cellular adhesion molecules (CAMs) have been shown to be predictors of all cause mortality in individuals with chronic renal failure 12 and patients with end-stage renal disease receiving haemodialysis 3. In renal transplant recipients the predictive value of CAMs has not been well characterised. The aim of this study was to assess the relationship between ...

Most patients (about 85%) seen in the ED to rule out an acute coronary event do not have acute coronary disease. In addition, the presenting ECG findings have been nondiagnostic in 50% of patients with acute MI. Our current knowledge of atherosclerosis as being a chronic low-grade inflammatory process triggered the search for reliable serum markers that have improved the diagnostic accuracy man...

Adhesion molecules mediate cell-cell and cell-matrix interactions and are essential for numerous physiological and pathological processes. Recent evidence from many laboratories suggests that adhesion molecules play an important role in tumor progression and may promote tumor growth and organ-specific metastasis. Certain adhesion molecules may also function as tumor suppressors. In this review,...

Several data have shown that the neural cell adhesion molecule (NCAM) is necessary for long-term memory formation and might play a role in the structural reorganization of synapses. The NCAM, encoded by a single gene, is represented by several isoforms that differ with regard to their content of alpha-2,8-linked sialic acid residues (PSA) on their extracellular domain. The carbohydrate PSA is k...

Dendritic cells (DCs) possess a number of unique features that distinguish them from other APCs. One such feature is their ability to trigger Ag-independent responses in T cells. Previous studies have focused on mature DCs, but the prevalence of this phenomenon in the resting-state immature DCs has never been considered. In this study, we show that, in the absence of Ag, human immature DCs trig...

Hematogenous dissemination of melanoma is a life-threatening complication of this malignant tumor. Here, we identified junctional adhesion molecule-C (JAM-C) as a novel player in melanoma metastasis to the lung. JAM-C expression was identified in human and murine melanoma cell lines, in human malignant melanoma, as well as in metastatic melanoma including melanoma lung metastasis. JAM-C express...
