| 8 | 8 | ## Overview |
| 9 | -CD70 is a costimulatory molecule expressed on some activated lymphocytes and has a role in T-cell-mediated immune responses. CD70 aberrations are relatively common in DLBCL and appear more frequent in certain DLBCL patient populations. For instance, in a Chinese DLBCL cohort, 24% of cases exhibited CD70 genetic changes, compared to 10.8% in a Swedish cohort.<sup>1</sup> CD70 mutations are associated with the BN2 genetic subtype of DLBCL.<sup>2</sup> The mutation pattern in CD70 is consistent with the preferential accumulation of *inactivating mutations*. Loss of CD70 protein expression has been described.<sup>1</sup> Genetic perturbation limits the development of an effective CD8+ T-cell immune response in Bcl6-driven DLBCL. [@nieDualRoleCD702022b] |
