T细胞CD4+记忆细胞是一类具有记忆功能的T细胞。当身体面对具有威胁性的抗原时,这些细胞会感应、分化并进一步成为不同类型的细胞来应对威胁。然而,在此过程中,一些细胞会留下并转变为记忆细胞,以备将来再次感应到相同抗原时能够更快地做出反应。 2. T细胞CD4+记忆细胞的功能 T细胞CD4+记忆细胞在人类免疫系统中发挥着多...
EasySep™人静息性CD4+T细胞分选试剂盒设计通过免疫磁珠负选方式,从新鲜或冻存的外周血PBMC、白细胞单采术中分离静息性CD4+T细胞。四聚体抗体混合物和磁珠标记不需要的细胞。利用EasySep™磁极将标记的细胞分选出来,无需使用分离柱。 非目的细胞被吸附在管壁上,目的细胞被倒入新的离心管中。
另外,正常的T细胞和靶细胞之间为了形成免疫突触要保持一定的距离,因为抗原多肽-MHC的大小是固定的,所以这个细胞间距离大约是13-15nm,但细胞外的抗原大小通常是不固定的,因此在CAR-T细胞和靶细胞之间这个细胞间距是随着抗原的大小和位置变化...
Latent HIV-1 infection of resting CD4 + T cells provides a long-lived reservoir of viral persistence in patients on antiretroviral therapy (ART). Intensive research into the mechanisms of HIV-1 latency has led to the identification of numerous potential therapeutic targets that might be exploited ...

1,2,5, Vanessa A. Evans1,2,5, Sharon R. Lewin1,2,5 and Paul U. Cameron1,2,5* Abstract Background: Combination antiretroviral therapy (cART) is able to control HIV-1 viral replication, however long-lived latent infection in resting memory CD4+ T-cells persist....
cells and tissue reservoirs (e.g., lymph node, spleen, bone marrow) following HIV-1 infection with the CCR5-tropic JR-CSF strain and suppression of viremia by ART. Replication-competent virus was recovered from pooled resting CD4⁺ T cells in 7 of 16 mice, with a median frequency of ...
(A) Resting memory CD4 T cells were stimulated with SDF-1 (12.5 nM) for various times, stained with FITC-phalloidin, and then analyzed with flow cytometer. (B) Resting memory CD4 T cells were stimulated with HIV-1NL4-3 for various times and similarly stained with FITC-phalloidin and analy...
In an in vitro coculture model of monocyte-derived, cultured human dendritic cells (DC) with autologous CD4(+) resting T cells, CCR5 (R5)-tropic strains of HIV-1, but not CXCR4 (X4)-tropic strains, were transmitted to resting CD4+ T cells, leading to prolific viral output, although DC...
