Levels of sTNF-RI and sTNF-RII in sera from healthy donors and leprosy patients (with TT and LL forms and type I and type II reactional states of the disease). The amount of sTNF-RI (○) or sTNF-RII (•) in human sera was analyzed by an enzyme-linked immunosorbent assay. Results are expressed as horizontal bars that indicate median values. P values indicate results that are significantly different from results for healthy donors (P < 0.05; Mann-Whitney U test).
