Changes in the TLR2 expression after rhIL-15 stimulation appear to havea favorable effect on mechanism recognition of Bb. The relations between IL-6 and its regulators (sIL-6Rα and sgp130) as well as between IL-1β and its regulators (IL-1Ra and sIL-1RII) after rhIL-15 stimulation may lead to enhanced IL-1β- and IL-6-mediated inflammatory reactions in the course of Lyme disease. Here, TLR2 is linked to Lyme disease.
