Low versus high density of immobilized anti-CD3 influences IL-4 regulation of T-cell immune responses.

abstract：:Endogenous retroviral superantigens such as vSAG-7 are highly stimulatory for T cells through interaction with the T cell receptor on the basis of V beta usage. Priming of adult MMTV 7-negative mice with vSAG-7-expressing cells has been shown to result in peripheral V beta 6/CD4+ T cell activation followed by toleranc...
