Correlations of B cells with the normalized RNA expression of both IFNγ (a) and IL-15 (b), and IFNγ producing CD8⁺ T cells (c) in the human BM. B cells are defined as CD19⁺ lymphocytes, T cells are defined as CD3⁺ lymphocytes. Cells were stimulated with PMA and Ionomycin for 4 h at 37 °C. Correlation coefficients (r_p) and significances were calculated according to Pearson with correction for age
