Herein, we measured TLR-4 and TLR-9 RNA levels and consequently TNF-α and IFN-α production in peripheral blood mononuclear cells (PBMCs) of patients with CVID and XLA.
In this study LPS (TLR4) or an imidazoquinoline compound (TLR7/8) activated XLA neutrophil shedding of surface CD62L, and phosphorylated MAP kinases p38, JNK and ERK.
