致病因素

Background: Seasonality in the occurrence of a disease often suggests the presence of environmental factors in its etiology.

背景 当疾病的发生率呈现明显的季节性分布时，常暗示环境因素在致病机转中占有一重要的角色。

The dimorphic transition of yeast and hyphal forms is one of most determinants in Candida albicans for its pathogenicity. This transition is regulated by several signal transduction pathways.

白念珠菌的形态转换是其致病性最重要的决定因素之一，这种形态变化受各种外界信号和细胞内信号转导途径的调控。

It can grow as yeast form, hyphal form and pseudohyphal form. Morphogenesis and virulence of C.

3Genetic factors play a major role inthe control of immune regulation,such as the expression of cytokines.An analysisof TNF〓 gene polymorphism in IgAN and HSP nephritis is beneficial to better un-derstanding of immunogenetic abnormalities in these diseases.But further inves-tigation on a large scale is necessary in order to find out the susceptibility genes orthe markers for a closely-linked susceptibility locus.

某些免疫相关基因是细胞因子表达、调控的决定因素，本实验通过〓基因多态性分析对部分肾小球疾病的遗传背景进行了有益的探索性研究，但是要最终找到致病基因或者连锁遗传标志，尚有待进一步的大规模研究。
