NK cell activity is regulated by the integration of positive and negative signals. One important source of these signals for human NK cells is the killer Ig-like receptor (KIR) family, which includes both members that transduce positive and those that generate negative signals. KIR3DL1 inhibits NK cell activity upon engagement by its ligand HLA-Bw4. The highly homologous KIR3DS1 is an activatin...

We validate a computational setup based on density functional theory to investigate hexagonal boron nitride (h-BN) monolayers grown on different transition metals exposing hexagonal surfaces. An extended assessment of our approach for the characterization of the geometrical and electronic structure of such systems is performed. Due to the lattice mismatch with the substrate, the monolayers can ...

Metabolism of sphingolipids into downstream lipid mediators followed by signaling modulates tumor microenvironment and the cancer cells to influence tumor progression. As such, sphingolipid signaling represents a novel way to modulate tumor biology. Neuroblastoma (NB), the most common extracranial solid tumor of childhood, is highly angiogenic and often displays poor prognosis. However, the rol...

MUC1 is a polymorphic, highly glycosylated, type I transmembrane protein expressed by ductal epithelial cells of many organs including pancreas, breast, gastrointestinal tract, and airway. MUC1 is overexpressed and differentially glycosylated by adenocarcinomas that arise in these organs, and is believed to contribute to invasive and metastatic potential by contributing to cell surface adhesion...

BACKGROUND Prolonged exercise in human athletes is associated with transient impairment of left ventricular (LV) function, known as cardiac fatigue. Cardiac effects of prolonged exercise in horses remain unknown. OBJECTIVES To investigate the effects of prolonged exercise on LV systolic and diastolic function in horses. ANIMALS Twenty-six horses competing in 120-160 km endurance rides. ME...
