麻风是由麻风杆菌引起的原发于皮肤和神经的慢性肉芽肿性多系统受累的疾病。麻风病呈光谱样表现,在结核样型端损害最少,瘤型端则呈多发性,并可呈系统性受累。B 淋巴细胞多克隆的激活导致形成循环免疫复合物(CICs),且在麻风反应时增加. Leprosy is a chronic, granulomatous, multisystemic disorder of primary origin in the skin and nerves caused by leprosy. Leprosy showed spectral performance, the least damage in the tuberculosis-like end of the tumor-side was multiple, and may be systematically involved. Activation of polyclonal B lymphocytes leads to the formation of circulating immune complexes (CICs) and increases upon leprosy reaction.
