Imiquimod triggers TLR7-independent apoptosis but TLR7-dependent activation in murine CD4+ T cells.
Toll-like receptor 7 (TLR7) agonists are widely used as immunomodulatory agents, yet their direct effects on T cells remain incompletely understood. Here, we investigated the effects of imiquimod (IMQ) on purified murine CD4+ T cells using TLR7-deficient mice and pharmacological approaches. IMQ elicited both activating...
