CTLA-4 (CD152) can inhibit T cell activation by two different mechanisms depending on its level of cell surface expression. Hodgkin and Reed-Sternberg cells represent an expansion of a single clone originating from a germinal center B-cell with functional immunoglobulin gene rearrangements but defective immunoglobulin transcription. Even more, EBV relatedness in several of the above listed instances may even stand for distinct diseases, as it has been shown for DLBCL and PTLD (104) and recently also for plasmablastic lymphoma (119) that EBV-positive and EBV-negative tumors have both different pathogenesis as well as different prognosis. Xing et al. doi:10.1016/S1470-2045(12)70582-X, 15. Thorough research has elucidated several mechanisms how this is achieved, it has also become clear that both tumor cells and microenvironmental compounds should be considered and modulated in a proper manner. Pioneering studies investigating the cancer EV-immune cell outcome evidenced how detrimental these small vesicles could be, leading to the discovery of a continuously growing number of EV-mediated mechanisms involved in tumor promotion and immune evasion prevailing over immune activation and tumor attack. doi:10.1038/nri1961, 7.

Mechanisms of Immune Evasion and Immune Modulation by Lymphoma Cells. Epstein–Barr virus’s role in lymphomagenesis was first discovered in Burkitt lymphoma (BL). Pradhan D, Biswasroy P, Goyal A, Ghosh G, Rath G. AAPS PharmSciTech. Upon T-cell receptor (TCR) stimulation and ligation with either PDL1 or PDL2, the ITSM and ITIM undergo phosphorylation, leading to the recruitment of the phosphatases SHP-1 and SHP-2, which in turn lead to dephosphorylation (inactivation) of the crucial T-cell signaling molecules ZAP70 and CD3ζ, and, in addition, of the phosphatidylinositol 3-kinase, which interrupts AKT and ERK signaling; even more, upon PD1 engagement by PDL1, protein tyrosine kinase-θ, which is necessary for the activation of the transcription factors NFκB and AP1, is attenuated and the negative regulator of T-cell activation, the E3 ubiquitin ligase CBL-b is upregulated (56–58). Importantly, in extranodal natural killer (NK)- and T-cell lymphoma of the nasal type, which is known to have an aggressive and mostly fatal course, PDL1 is substantially upregulated due to EBV infection of the tumor cells, and PD1 blockade has been shown to be very effective in otherwise hopeless relapse cases in a small case series (61).

Of course, the interaction of a … Other genes in this region encompass JAK2, PDL2, and JMJD2C, the upregulation of all of which seems to be vital for HRS cells (30), explaining why blocking PD1 might be more effective than blocking PDL1 in cHL as the first might prevent the tumor cells also from relying on PDL2 as a substitute of blocked PDL1 (31). Liu WR, Shipp MA. Cancer Sci (2017) 108(4):574–80. doi:10.1182/blood-2008-07-168468.
