- 血小板和T细胞活化抗原1(platelet and T cell activation antigen 1，PTA1)最早在1985年由Bums等发现。 由于其表达于人活化T细胞而被命名为TLiSA1抗原(T lineage specific activation antigen 1，TLiSA1)。Platelet and T cell activation antigen 1 (PTA1) was initially reported by Burns in 1985 with the name TLiSA1 (T lineage specific activation antigen 1, TLiSA1 ), and was renamed as PTA1 in 1989 because of its expression on platelet as well.
- 方法 测定 40例AMI、45例UAP患者发病 2 4h和 1周时血清sICAM 1、sVCAM 1、D 二聚体、PF4 并与 30例对照组比较。Methods The levels of serum sICAM 1,sVCAM 1,D D and PF 4 were measured in 40 patients with AMI,45 patients with UAP within 24 hours and one week after onset of the disease and 30 normal controls.

- PF4属于CXC趋化因子非ELR基序的亚型,具有ELR基序的有血管新生刺激活性,而PF4无此基序,故没有促进血管新生的作用,反而抑制血管的生成。PF4 belongs to the subgroup of non-ELR CXC chemokines. Chemokines with ELR can stimulate newborn blood vessel development, but PF4 has no such effect.
- 人胰岛素样生长因子2(Insulin-like growth factor 2，IGF2)和H19即为研究较早的一对相互毗邻的印记基因。Insulin-like growth factor 2 (IGF2) and H19 are two imprinted genes located adjacent to each other at chromosome 11p15.5 in humans.
