Abstract
OBJECTIVE The aim of this study was to evaluate the association of -924 G>A (rs2232365) and -3279 C>A (rs3761548) FOXP3 variants with IBD susceptibility, clinical and endoscopic activity, and IL-10 and TGF-β1 plasma levels. METHOD The study included 110 IBD female patients, 60 with Ulcerative Colitis (UC) and 50 with Crohn's Disease (CD), and 154 female controls. FOXP3 variants were determined with Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Plasma levels of IL-10 and TGF-β1 were determined using immunofluorimetric assay. RESULTS AA genotype of rs2232365 and rs3761548 was associated with CD (OR = 3.147, 95% CI 1.015-9.758, p = 0.047) and UC (OR = 3.221, 95% CI 1.050-9.876, p = 0.041) susceptibility, respectively. However, were not associated with TGF-β1 and IL-10 levels, and endoscopic/clinical activity disease. GAGA haplotype was associated with IBD (OR = 4.003, 95% CI 1.100-14.56, p = 0.035) and UC susceptibility (OR = 6.107, 95% CI 1.609-23.18, p = 0.008). In addition, IBD patients with the GAGA haplotype had lower TGF-β1 levels (p = 0.041). Moreover, G/C haplotype (dominant model) had a protective effect of 60% in CD susceptibility and lower Endoscopic Severity Index. CONCLUSIONS These results suggest that FOXP3 variants could exert a role in the Treg, which could be one of the factors involved in the susceptibility and pathogenesis of IBD.

Abstract
Entre os animais silvestres envolvidos em tráfico/comércio ilegal no Brasil, as aves compreendem um dos grupos mais atingidos, especialmente devido a características como canto e colorido das penas. Atualmente, análises genéticas compreendem uma das formas mais eficazes de gerar dados para solucionar e minimizar os resultados de crimes ambientais e comércio ilegal de animais silvestres. Uma das análises genéticas que podem ser utilizadas com o intuito de subsidiar programas conservacionistas associados ao tráfico ilegal de aves refere-se à sexagem molecular, dado que neste grupo de vertebrados nem sempre é possível identificar o gênero por meio de caracteres morfológicos. A sexagem molecular pode ser feita com base em amostras de DNA obtidas de diferentes fontes, como penas e sangue, e posterior amplificação de regiões dos genes CHD-Z e CHD-W (chromo helicase-DNA binding). Os dados de perfis genéticos sexoespecíficos servem de subsídio a programas conservacionistas de manutenção e/ou reprodução em cativeiro e posterior soltura ou reintrodução dos animais em ambiente natural.
