Methods to activate or block the HLA-E/Qa-1 restricted CD8+ T cell regulatory pathway to treat immunological diseaseMethods are provided for inhibiting or enhancing down-regulation of an antigen-activated HLA-E + T cell by an HLA-E-restricted CD8 + T cell comprising contacting the HLA-E +...
4b). Single knockout of sirtuin members did not block LCA-mediated AMPK activation or V1E1 deacetylation; although Sirt1 knockout had a mild effect (Extended Data Fig. 4c–k; for validation data, see Supplementary Table 2). This result suggested that sirtuins redundantly regulate AMPK by ...
To verify whether senescent epithelial cells-induced fibroblast activation was mediated through exosome secretion, senescent MLE-12 cells were pretreated with GW4869, a noncompetitive inhibitor of N-SMase, to block exosome secretion. Then, senescent MLE-12 cells were cocultured with pulmonary fibroblast...
For staining, collected cells were first treated with CD16/32 antibody (Biolegend, 101320; 1:1000 dilution) to block Fc receptor-mediated nonspecific binding. For staining of intracellular markers, GolgiPlug (BD, 555029) was added to the cell culture medium 4 h before cell collection. Followi...
(Fig.1). Based on these factors, although Kasumi-1 cells do not resemble quiescent LSCs, we measured whether the cell cycle block and the increase in GATA2 binding would lead to a reactivation of LSC-specific genes. To this end, we assessed transcription factor binding and histone ...
(i.e., those in the last step of this cascade; active growth) and do not block any of the intermediate steps. Understanding the mechanisms that regulate the ability of disseminated tumor cells (DTCs) to complete all steps of metastasis will reveal additional targets for novel anti-metastatic ...

(Supplementary Fig.1g, h). We also confirmed endogenous interaction between FOXQ1 and RbBP5 in various tumor types, including TNBC (Fig.1g). Our mass spectrometry proteomics failed to identify any KMT2/MLL enzymatic subunits in the FOXQ1 complex, likely due to the large protein sizes of ...
of elicitation of VRC01-like bNAbs by previous Env immunogens is the inability of such proteins to activate the appropriate naive B cells upon immunization12,13. As such our study further illuminates a path to overcome the earliest block in the elicitation of VRC01-class bNAbs by immunization....
