متن کاملTumor-fighting T cells lose their way
Like a tourist without a map, tumor-fighting T cells have a hard time finding their destination without directions. According to Clark et al. (page 2221), dismantling these directions helps skin cancer cells hide from killer T cells. To enter the skin, T cells must grab on to the adhesive molecule E-selectin, which is expressed on the endothelial cells lining blood vessels in the skin. The auth...
متن کاملHow b - skeletons lose their edges
A b-skeleton is a proximity graphs with node neighbourhood defined by continuous-valued parameter b. Two nodes in a b-skeleton are connected by an edge if their lune-based neighbourhood contains no other nodes. With increase of b some edges a skeleton are disappear. We study how a number of edges in b-skeleton depends on b. We speculate how this dependence can be used to discriminate between ra...
