Figure Lengend Snippet: FIG. 1. Circulating CXCL10 in leprosy patients and healthy con- trols. Each point represents one sample from a different individual. The groups were healthy controls, borderline tuberculoid without re- action (BT), borderline lepromatous without reaction (BL), polar lep- romatous without reaction (LL), BT with reaction (BT plus RR), BL with reaction (BL plus RR), and LL patients with T2R (erythema nodosum leprosum). For patients with reaction (BT plus RR, BL plus RR, and T2R), the sample was taken at the time of reaction, prior to treatment. For LL, n 6; for all other groups, n 10. The horizontal lines indicate median values. The median level of CXCL10 in LL patients with type 2 reaction was not significantly elevated (P 0.9).

Article Snippet: Tissue sections were stained by an indirect immunoperoxidase method using goat anti-human CXCL10 (R&D Systems, Inc.; 1:40) or rabbit anti-human CXCR3 (Sigma) (1:75) for 60 min, followed by biotinylated donkey anti-goat IgG or goat anti-rabbit IgG (both 1:40; Jackson ImmunoResearch Laboratories, Inc.) for 30 min. Peroxidase-conjugated avidin-biotin complexes (Vectastain Elite ABC Reagent kit) were applied for 30 min. All incubations were followed by three washes with phosphate-buffered saline isotonic buffer, pH 7.4.

Figure Lengend Snippet: FIG. 2. Circulating CXCL10 in repeated samples from leprosy patients who developed T1R. Each graph depicts the measurements made from serum samples obtained at 1 month intervals in borderline tuberculoid (A, no. 1 to 10) and borderline lepromatous (B, no. 11 to 20) patients. All patients with clinical T1R received standard multidrug treatment starting at the first visit. The arrows indicate the visits at which T1R was diagnosed. The number above each time point indicates the dose of prednisone started on that day, tapered monthly as indicated; in some cases, corticosteroids were not used initially but were started 1 to 2 months after the initial clinical diagnosis of T1R. Each serum specimen was obtained before corticosteroid treatment was initiated. CXCL10 was significantly elevated during T1R in the 10 BT patients (A) (P 0.0006) and the 10 BL patients (B) (P 0.0001). In patients 12, 16, and 17 (B), T1R was diagnosed by histopathological criteria only; when they were excluded from the analysis, the association of T1R with CXCL10 remained significant (P 0.05).

Figure Lengend Snippet: FIG. 3. Expression levels of CXCL10 and IFN- genes in skin biopsy specimens from leprosy patients. (A to H) Real-time quantitative RT-PCR was performed on cDNA obtained from sequential skin biopsy specimens from individual leprosy patients who were placed on MDT, none of whom had T1R at the time of the first biopsy. Five patients (A to E) had clinical symptoms of T1R at the time of the second biopsy; two of these (C and D) had a third biopsy after the reaction had resolved. Three patients (F to H) had no clinical symptoms of T1R at the time of the initial or second biopsy. Data were obtained using the standard-curve method and were normalized using 18S rRNA values, repeated three times for all determinations. The results are presented as the mean standard deviation.
