Phylogenetic analysis of the genus Bifidobacterium and related genera based on 16S rDNA sequences.

abstract：:The concept of superantigens is well-known and widely accepted. In this brief communication, we analyze the behaviour of antigen-presenting cells after T-cell activation by staphylococcal enterotoxin B, a representative superantigen. We tried to activate murine T cells by inflammatory mouse peritoneal macrophage in th...
