近日,北卡罗来纳大学莱恩伯格综合癌症中心团队在The Lancet Haematology上发表题为Anti-CD30 CAR T cells as consolidation after autologous haematopoietic stem-cell transplantation in patients with high-risk CD30+ lymphoma: a phase 1 study的文...
激动选择后的非经典 T 细胞主要可分为3类,分别是FOXP3+调节性T细胞(regulatory cell,Treg)、自然杀伤性T 细胞(natural killer T cell,NKT)和 TCRαβ+CD8αα+T 细胞[16, 18]。不识别自身抗原肽的 T 细胞进一步分化为成熟的 CD4+或 CD8+SP ...
a,d, Inset numbers denote absolute event counts of the indicated cell populations. e, Tandem mass spectrometry fragmentation spectra of TdT peptide-1 and -3 identified from leukemia cells of patient no. 119N. f, Expression of CD19 and TdT in leukemia cells before and after relapse from CD...
The PDCD1-encoded immune checkpoint receptor PD-1 is a key tumor suppressor in T cells that is recurrently inactivated in T cell non-Hodgkin lymphomas (T-NHLs). The highest frequencies of PDCD1 deletions are detected in advanced disease, predicting inferior prognosis. However, the tumor-suppress...
用抗CD45(eBioscience)标记50 ul血液,使用BD FACS裂解液裂解,并在BD Fortessa细胞计数仪上使用CountBright Absolute计数微珠(Thermo Fisher)定量。 为了进行血液、脾脏和肿瘤的表型分析,对小鼠实施安乐死,并通过心脏穿刺采集血液。 机械分离脾脏和肿瘤,并在PBS中洗涤两次。 在室温下,用ACK裂解缓冲液(Fisher Scientific...

The T-cell receptor (TCR), located on the surface of T cells, is responsible for the recognition of the antigen-major histocompatibility complex, leading to the initiation of an inflammatory response. Analysing the TCR repertoire may help to gain a better understanding of the immune system featur...
THROMBOCYTEST® plus allows the flow cytometric determination of reticulated platelets and the absolute count determination of thrombocytes during thrombocytopenia (number of thrombocytes < 20.000/µl). The test kit contains a RNA specific dye which stains the RNA from reticulated platelets, ...
Changes in the number of each cell are shown in Fig. 1. Fig. 1 Cellular kinetics after the injury of skeletal muscle. Neutrophils appear on Day 0, peak on Day 1, and disappear on Day 4; Treg appear on Day 0, peak on Day 4, and decrease to half the peak on Day 14; Tconv ...
This illustrates a degree of immune recovery that occurs with virologic suppression that is not reflected in absolute CD4+ T-cell count or percentage and suggests that guidelines for P. jiroveci pneumonia prophylaxis may need to be re-evaluated. 展开 ...
