In addition, CD19+CD27− naïve B cells isolated from dengue patients were refractory to TLR/anti-IgM stimulation in vitro, which correlated to the increased expression of inhibitory Fcγ receptors (FcγR) CD32 and LILRB1 on CD19+CD27− naïve B cells from DENV-infected patients. Here, FCGR2A is linked to dengue disease.
