背景介紹：Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.

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

2.陽性細(xì)胞分布可分為灶型和彌漫性

3.由于細(xì)胞內(nèi)含抗原量不同，所以染色強(qiáng)度不一。如果細(xì)胞之間染色強(qiáng)度相同，常提示其反應(yīng)為非特異性

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

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