目的研究趋化因子γ干扰素诱导蛋白10(IP-10)在病理性瘢痕中的表达,探讨其在病理性瘢痕发病机制中的作用。方法应用免疫组化技术检测趋化因子IP-10在28例瘢痕疙瘩(K组)、34例增生性瘢痕(HS组)及20例正常皮肤(N组)中的表达,并进行统计学分析。结果IP-10在K组及HS组中均呈高表达,与N组比较差异均具有统计学意义(P〈0.01),但K组与HS组之间差异无统计学意义(P〉0.05)。结论IP-10可能通过趋化T淋巴细胞定向迁移,引发一系列免疫炎性反应,从而促进病理性瘢痕的形成。
Objective To explore the expression of 10 kDa interferon-gamma-induced protein (IP-10)in pathological scar and its role in the pathogenesis of pathological scar. Methods Immunohistochemistry was performed to detect the expression and distribution of IP-10 in 28 patients with keloid(group K),34 patients with hypertrophic scar(group HS),and 20 normal controls(group N). The data were collected and analyzed statistically. Results The expression of IP-10 was significantly higher in groups K and HS than in group N (P 0.01), but no significant difference in the expression of IP-10 was found between groups K and HS. Conclusion IP-10 may enhance the formation of pathological scar by attracting T lymphocytes and inducing immune/inflammatory response.
