Abstract

The paper presents new data on T-lymphocyte expression of plexin B1, a high-affinity receptor for class IV semaphorin Sema4D, which expression was previously attributed exclusively to non-immune cells. The biological significance of this phenomenon, as well as its role in the regulation of T-lymphocyte functions are discussed, primarily of cell migration.
