The transactivator of transcription (Tat) is a HIV regulatory protein which promotes viral replication and chemotaxis. HIV-1 shows extensive genetic diversity, HIV-1 subtype C being the most dominant subtype in the world. Our hypothesis is the frequency of CSF CD3CD56 and CD3CD56 is reduced in HIV-1C compared to HIV-1B due to the Tat C30S31 substitution in HIV-1C. 34 CSF and paired blood samples (PWH, n = 20; PWoH, n = 14) were studied. In PWH, the percentage of CD3CD56 was higher in CSF than in blood (p < 0.001), comparable in both compartments in PWoH (p = 0.20). The proportion of CD3CD56 in CSF in PWH was higher than PWoH (p = 0.008). There was no subtype differences. These results showed CNS compartmentalization of NKT cell response in PWH.
转录激活物(Tat)是一种 HIV 调节蛋白,可促进病毒复制和趋化性。HIV-1 表现出广泛的遗传多样性,HIV-1 亚型 C 是世界上最主要的亚型。我们的假设是,由于 HIV-1C 中的 Tat C30S31 取代,与 HIV-1B 相比,HIV-1C 中 CSF CD3CD56 和 CD3CD56 的频率降低。研究了 34 例 CSF 和配对的血液样本(PWH,n=20;PWoH,n=14)。在 PWH 中,CSF 中 CD3CD56 的百分比高于血液(p<0.001),在 PWoH 中两个部位相当(p=0.20)。PWH 中 CSF 中 CD3CD56 的比例高于 PWoH(p=0.008)。没有亚型差异。这些结果表明,在 PWH 中,NKT 细胞反应存在中枢神经系统区室化。
