Dementia and Parkinson's disease are the two most common age-related neurodegenerative conditions. Recent studies have identified Human Leukocyte Antigen (HLA) Class II DRB1 alleles that are protective or neutral with respect to dementia. Here we extend those findings to evaluate the association of the population frequency of HLA DRB1 alleles with the prevalence of dementia and Parkinson's disease in14 Continental Western European countries. Nine HLA DRB1 alleles were identified including four that are protective against dementia (DRB101:01, DRB104:01, DRB113:02, DRB115:01), three that are neutral (DRB103:01, DRB107:01, DRB108:01), and two susceptibility alleles (DRB111:01, DRB1*04:05). Results demonstrated that the population prevalence's of dementia and Parkinson's disease are highly correlated and that the association between the nine DRB1 alleles above and the population prevalence of dementia is highly overlapping with that of Parkinson's disease. These findings suggest a common HLA Class II DRB1 profile. Given the diverse role of HLA Class II alleles in protection from foreign antigens, autoimmunity, and, possibly, neuroprotection, the shared HLA profile between dementia and Parkinson's disease indicates that common immunogenetic mechanisms underlie the pathogenesis and manifestation of these diseases.
痴呆症和帕金森病是两种最常见的与年龄相关的神经退行性疾病。最近的研究已经确定了人类白细胞抗原(HLA)II类DRB1等位基因,这些等位基因对痴呆症具有保护作用或呈中性。在此,我们扩展这些发现,以评估HLA DRB1等位基因的人群频率与14个西欧大陆国家痴呆症和帕金森病患病率之间的关联。我们确定了9个HLA DRB1等位基因,其中4个对痴呆症有保护作用(DRB101:01、DRB104:01、DRB113:02、DRB115:01),3个呈中性(DRB103:01、DRB107:01、DRB108:01),还有2个易感等位基因(DRB111:01、DRB1*04:05)。结果表明,痴呆症和帕金森病的人群患病率高度相关,并且上述9个DRB1等位基因与痴呆症人群患病率之间的关联与帕金森病的关联高度重叠。这些发现表明存在一种共同的HLA II类DRB1特征。鉴于HLA II类等位基因在抵御外来抗原、自身免疫以及可能的神经保护方面具有多种作用,痴呆症和帕金森病之间共享的HLA特征表明,这些疾病的发病机制和表现有共同的免疫遗传机制。
