背景介紹：Host cell factor (HCF) is a cellular cofactor required for the activation of VP16 which expresses the herpes simplex virus immediate early gene. V16 binds to HCF through a 4-amino acid motif similar to the HCF binding domain of the basic leucine-zipper proteins Luman and Zhangfei (ZF). Luman activates promoters containing cAMP or unfolded protein response elements (UPRE). Zhangfei suppresses the transcriptional activity of Luman, but requires HCF binding which may target Luman and Zhangfei to a common location. Sequence analysis predicts that the deduced 272-amino acid Zhangfei protein has a negatively charged N terminus, a leucine zipper of 6 heptad leucine repeats separated by a conserved 6-amino acid spacer, a basic domain, and a bZIP region. It is also presumed that the N-terminal acidic region of Zhangfei is an activation domain.

1.陽性細胞染色分布有三種類型：細胞漿、細胞核、細胞膜表面。大部分抗原見于細胞漿，可見于整個胞漿或部分胞漿

2.陽性細胞分布可分為灶型和彌漫性

3.由于細胞內含抗原量不同，所以染色強度不一。如果細胞之間染色強度相同，常提示其反應為非特異性

4.陽性細胞染色定位于單個細胞，且與陰性細胞相互交雜分布；而非特異性染色常不限于單個細胞，而是累及一片細胞。

5.切片邊緣、刀痕或褶皺區(qū)域，壞死或擠壓的細胞區(qū)，膠原結締組織等，常表現(xiàn)為相同的陽性染色強度，不能用于判斷陽性。
