since the t3 complex is not a specific marker of any particular effector t cell population , but it is found on all t lymphocytes , we favor the hypothesis that the complex is involved in a more fundamental step of t cell activation , and we believe that triggering of the 'lethal hit ' , expression of il2 receptors , and secretion of il2 are mere manifestations of this basic process .
