Chronicity maybe result from many factors with complex mechanism.HCV may evade the host immune surveillance due to the hypermutation of HCV gene; HCV has the nature of pantropic,the tissues outside liver can provide virus for repeatedly infection of liver; The HCV receptors,such as CD81,LDL receptor,scavenger receptor B type I,L-SIGN,DC-SIGN and so on,may influence organism humoral immunity and the cellular immunity function in different degrees; HCV infection also may cause the reduction of quantity of organism immune cell or functional defect,low response of humoral immune response,tolerance of cellular immunity,then,the host finally transforms into chronic infection condition.

其慢性化的机制非常复杂，是由多个因素造成的，HCV因其基因高变性可以逃避宿主的免疫监视；HCV具有泛嗜性，肝外组织又可为肝组织的反复感染提供病毒来源；CD81、LDL受体、清道夫受体B类Ⅰ型及L-SIGN、DC-SIGN等HCV受体又可不同程度地影响机体的体液免疫和细胞免疫功能；HCV感染亦可直接导致机体免疫细胞数量减少或功能缺陷，体液免疫应答水平低下、细胞免疫耐受，宿主最终转变为慢性感染状态。

FIZZ1 had no effect on the expression of scavenger receptor CD36 in cultured macrophages. FIZZ1 can promote the development of AS by the up-regulation of the expression of SR-A and the phagocytose of fatty substance in VSMCs.

FIZZ1不影响体外培养的巨噬细胞清道夫受体CD36的表达，FIZZ1能促进ox-LDL诱导的体外培养的平滑肌细胞SR-A表达，从而可能加速平滑肌细胞吞噬脂质，促进动脉粥样硬化进展。

One of these factors encases the vegetative cells in a polymer capsule that inhibits ingestion by the immune system's macrophages and neutrophils—the scavenger cells that normally degrade disease-causing bacteria.

其中一个因子会把繁殖生长型细胞包在聚合物组成的荚膜里，以抑制巨噬细胞与嗜中性白血球的吞噬作用（上述这两种细胞是免疫系统的清道夫，可消灭致病细菌）。
