CD80, CD86 and CD40 Provide Accessory Signals in a Multiple‐Step T‐Cell Activation Model
1 Oct 1996
Abstract excerpt
In this review, a sequential multiple-step model for T-cell activation is proposed. In a series of in vitro studies, highly purified freshly isolated human peripheral blood T lymphocytes were stimulated through the CD28 receptor, with mAb or with natural ligands B7-1 or B7-2, along with TCR stimulation, in the absence of other costimulatory interactions. Ligation of the CD28 receptor, along with stimulation of...
