Cytotoxic-T-lymphocyte-mediated cytolysis of L cells persistently infected with Chlamydia spp.

Rasmussen, S J, Timms, P, Beatty, P R, Stephens, R S

Persistent chlamydial infections have been proposed as a means whereby chlamydiae evade immune resolution of infection. Such a mechanism would require evasion not only of the humoral immune responses...
