1. From naive to memory T cells;Swain;Immunol. Rev.,1996
2. Costimulatory requirements of naive CD4+ T cells. ICAM-1 or B7-1 can costimulate naive CD4 T cell activation but both are required for optimum response;Dubey;J. Immunol.,1995
3. CD28 engagement and proinflammatory cytokines contribute to T cell expansion and long-term survival in vivo;Vella;J. Immunol.,1997
4. High antigen density and IL-2 are required for generation of CD4 effectors secreting Th1 rather than Th0 cytokines;Rogers;J. Immunol.,1998
5. Control of CD4 effector fate: transforming growth factor β1 and Interleukin 2 synergize to prevent apoptosis and promote effector expansion;Zhang;J. Exp. Med.,1995
