LP skin lesion samples exhibited higher AIM2 transcript levels, similar NLRP1 levels and lower pro-IL-1\u03b2 mRNA levels compared with HC samples. We verified that, compared with PBMCs from HC subjects, PBMCs from patients with LP produced similar amounts of IL-1\u03b2 after induction by TLR4 agonists but lower IL-1\u03b2 levels after induction by TLR7\/TLR8 agonists, regardless of the addition of ATP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Alterations in innate immunity, such as inflammasome component expression in skin lesions and PBMCs, were observed in patients with LP.
