STAT3 and T-cell large granular lymphocyte leukemia: Of note, within TαβCD8+ LGLL cases, distinct profiles were further observed depending on the presence vs. absence of STAT3 mutations, since the reduced (vs. HD) normal WBC (p=0.007), neutrophil (p<0.001), basophil (p=0.08), dendritic cell (p=0.028) and NK-cell (p<0.001) counts found among TαβCD8+ LGLL cases were exclusively observed among those patients that carried STAT3 mutations, while normal (p>0.05) in STAT3 wild-type cases (Figure 3, Supplementary Table 5).
