However, absolute counts of naive and central memory CD4 T cells remained below normal levels. The only parameters significantly associated with CD4 counts at the end of follow-up were the pre-HAART CD4 count ( β± SD = 0.54 ± 0.16, P = 0.003) and the level of CD4 central memory ...
Central memory CD8+ T cells (Tcm) control systemic secondary infections and can protect from chronic infection and cancer as a result of their stem-cell-like capacity to expand, differentiate, and self-renew. Central memory is generally thought to emerge following pathogen clearance and to form ...
Of interest are adaptive responses, particularly pathogen-specific memory CD4 þ and CD8 þ T-cell- mediated responses essential for successful bacterial control during LTBI. BCG is generally considered to be inefficient in generating central memory CD4 þ and CD8 þ T-cell responses8, ...

tract infection Compared to healthy controls, patients with tuberculosis had a reduction in the population of GZMK-expressing CD8+ cytotoxic T cells and SOX4-expressing CD4+ central memory T cells, which conversely corresponded to an increase in the MKI67-expressing proliferating CD3+ T cell ...
significant increase in total number of T cells after JEV infection. Notably, the CD4+ T cells were found to be more enriched than CD8+ T cells (Fig.2F, G) [45,46]. To further confirm these findings, the IHC assay was performed, and consistent changes on Mon_Mac, Mic_Mac, T ...
cell population. Considering the diversity and importance of T cells in the TME, T cells were extracted and manually annotated into 7 clusters according to the distinct gene expression patterns of each cluster, including CD4+naive, Treg, CD4+exhausted, effect memory T-cell (TEM), CD8+naive, ...
Thus, Pik3cdE1020K/+ CD8+ T cells exhibit a pronounced effector-like phenotype with reduced expression of CD127 and TCF1, which are critical for the development of quiescent TCM cells. Activated PI3Kδ impairs memory T cell expansion following viral infection To determine whether Pik3cdE1020K/...
Cancer vaccines stimulate CD4+ T helper cells and CD8+ cytotoxic T lymphocytes to engage with TAAs to induce a specific adaptive immunologic response and to initiate immunologic memory to protect against further exposure to the antigens. A benefit of cancer vaccines is the low adverse effects...
(PCNSL) in AIDS75has been associated with infiltration of reactive T cells in the perivascular regions of the CNS76. PCNSL is diagnosed in 1.6–9.0% of patients with AIDS77,78, and susceptibility to PCNSL is inversely proportional to CD4+T cell count79,80. Notably, some HIV-positive ...
