CD19 and colorectal carcinoma: Moreover, the SNA binding cell number was significantly higher at CD11b+ and CD19+ cells from the spleen of CRC-bearing mice vs. controls (19.49 ± 3.88 vs. 7.86 ± 2.51, p = 1 × 10−6 and 8.61 ± 6.46 vs. 3.58 ± 1.62, p = 0.03), but, in the case of PBMCs, the number of SNA reactive cells was significantly lower at CD3+ T cells of CRC-bearing mice compared to the healthy controls (16.5 ± 10.55 vs. 27.81 ± 9.23, p = 0.02) (Figure 6A,B).
