DNA sequence variations of metalloproteinases: their role in asthma and COPD

Abstract: Asthma and chronic obstructive pulmonary disease (COPD) are complex genetic diseases that cause considerable morbidity and mortality worldwide. Genetic variability interacting with environmental and ethnic factors is presumed to cause tobacco smoke susceptibility and to influence asthma severity. A disintegrin and metalloproteinase 33 (ADAM33) and matrix metalloproteinase-9 (MMP9) appear to have important roles in asthma and COPD pathogenesis. ADAM33 and MMP9 genetic alterations could possibly contribute to th… Show more

“…Recent studies suggest that the etiologies of COPD among never smokers and ever smokers are potentially quite different, as exemplified by the 10% to 15% of COPD attributable to a1-antitrypsin deficiency, dust exposure, or chronic asthma. Furthermore, Li and colleagues and Sampsonas and colleagues reported that different genes may be relevant in nonsmokers (vs. smokers) with lung cancer or COPD (56,57).…”

“…O acúmulo de macrófagos nas paredes das vias aéreas e no parênquima pulmonar dos tabagistas que desenvolvem DPOC pode ser explicado tanto pelo prolongamento do tempo de vida da célula no pulmão como pelo aumento do recrutamento de monócitos (seu precursor) da circulação 13 . Alguns trabalhos sugerem que a participação dos macrófagos na patogênese da DPOC tem relação com a sua capacidade de produzir enzimas metaloproteases (MMP) como a MMP-1, MMP-9 e MMP-12 14,15,16,17 . Acredita-se que as metaloproteases sejam capazes de degradar proteínas de forma semelhante às enzimas neutrofílicas 14 e recrutar células inflamatórias da circulação, facilitando sua infiltração nos tecidos lesados 15 .…”

Macró-fagos recolhidos do lavado broncoalveolar (LBA) de pacientes com DPOC apresentam aumento da expressão de receptores para MMP-1 e MMP-9 16 , enquanto que tanto camundongos com deficiência de MMP-12 16 quanto o uso de inibidores de MMP em cobaias 18 apresentam efeito protetor à exposição à fumaça de cigarro.…”
