过敏性紫癜是儿童常见的自身免疫性小血管炎,其发病机制尚未完全明了.近年IgA介导的免疫学异常研究颇多,IgA沉积于受累肾小球系膜区及皮肤、肾小球、胃肠道血管壁,组织沉积原因可能涉及血清IgA产生增多、IgA特异性自身抗体异常、IgA1结构异常、IgA1受体表达异常、补体参与等,IgA的沉积介导黏附分子、细胞因子等表达异常.
過敏性紫癜是兒童常見的自身免疫性小血管炎,其髮病機製尚未完全明瞭.近年IgA介導的免疫學異常研究頗多,IgA沉積于受纍腎小毬繫膜區及皮膚、腎小毬、胃腸道血管壁,組織沉積原因可能涉及血清IgA產生增多、IgA特異性自身抗體異常、IgA1結構異常、IgA1受體錶達異常、補體參與等,IgA的沉積介導黏附分子、細胞因子等錶達異常.

Henoch-Schnlein purpura(HSP) is a common autoimmune small vessel vasculitis that primarily affects children.Although the pathogenesis of HSP is unknown,there are tantalizing clues on the immune abnormalities mediated by IgA,which mainly affects the vessels of the skin,gastrointestinal tract and kidneys.The reasons of deposition maybe involve in the increases of serum IgA,the abnormalities of IgA-specific autoantibodies,structures and acceptors of IgA1,complements,and so on,which mediates the abnormal expressions of adhesion molecules and cytokines.
