Wound healing genes and susceptibility to cutaneous leishmaniasis in Brazil: role of COL1A1.

ABSTRACT: Previous studies have demonstrated a role for wound healing genes in resolution of cutaneous lesions caused by Leishmania spp. in both mice and humans, including the gene FLI1 encoding Friend leukemia virus integration 1. Reduction of Fli1 expression in mice has been shown to result in up-regulation of collagen type I alpha 1 (Col1a1) and alpha 2 (Col1a2) genes and, conversely, in down-regulation of the matrix metalloproteinase 1 (Mmp1) gene, suggesting that Fli1 suppression is involved in activation of the profibrotic gene program. Here we examined single nucleotide polymorphisms (SNPs) in these genes as risk factors for cutaneous (CL) and mucosal leishmaniasis (ML), and leishmaniasis per se, caused by L. braziliensis in humans. SNPs were genotyped in 168 nuclear families (250 CL; 87 ML c
