Specific Mutation Predict Relapse/Refractory Diffuse Large B-Cell Lymphoma. (PubMed, J Blood Med)

The application of rituximab has significantly enhanced the overall survival rates in patients with diffuse large B-cell lymphoma (DLBCL)...In addition, we revealed mutations in HIST2H2AB, BCL2, NRXN3, FOXO1, HIST1H1C, LYN and TBL1XR1 genes were only detected in initial diagnostic biopsies, mutations in the EBF1 gene were solely detected in the rrDLBCL patients. Collectively, this study elucidates some of the genetic mechanisms contributing to the progression of rrDLBCL and suggests that the presence of CD58 mutations might serve as a powerful predictive marker for relapse/refractory outcomes in primary DLBCL patients.

CD58 alterations govern antitumor immune responses by inducing PD-L1 and IDO in diffuse large B-cell lymphoma. (PubMed, Cancer Res)

Notably, CD58 genetic alterations, along with low CD58 expression, significantly correlated with reduced rates of response to R-CHOP therapy and inferior progression-free and overall survival...Direct activation of CD58-CD2 costimulatory signaling in combination with anti-PD-L1 blockade or IDO inhibitor sensitized CD58-deficient DLBCL to CAR T-cell therapy. Collectively, this work identified the multiple roles of CD58 in regulating antitumor immune responses in DLBCL.

Genetic Characterization of Primary Mediastinal B-Cell Lymphoma: Pathogenesis and Patient Outcomes. (PubMed, J Clin Oncol)

This large-scale genomic characterization of PMBCL identified novel treatment targets and genetic lesions for refined risk stratification. DUSP2 and CD58 mutation analyses may guide treatment decisions between rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone and dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab.

CD58 Genetic Alterations and Its Contribution to Upregulation of PD-L1 and IDO Via LYN/CD22/SHP1 Axis in DLBCL (ASH 2023)

Patients with CD58 mutation, copy number loss or low expression exhibited lower complete response rates following first-line R-CHOP therapy, as well as significantly poorer PFS and OS... Our study comprehensively characterized CD58 genetic alterations in DLBCL. We demonstrated that CD58 downregulation or mutation led to upregulation of PD-L1 and IDO expression mainly by regulating the LYN/CD22/SHP1 axis. Moreover, we explored strategies to directly activate CD2 co-stimulatory signaling or in combination with immune checkpoint inhibitors to address the diverse effects of CD58 alterations.

Multi-Dimensional Molecular and Tumor-Microenvironment Analysis of Classic Hodgkin Lymphoma (ASH 2023)

Conclusion Our multi-dimensional profiling approach enabled us to delineate molecular profiles of HRS cells that are linked to distinct TME patterns. These linkages have implications for current pathogenesis models, molecular subtyping of CHL, and identification of cellular vulnerabilities that might be therapeutically exploitable via targeting of HRS cell phenotypes and/or immune escape mechanisms.

PAX5 epigenetically orchestrates CD58 transcription and modulates blinatumomab response in acute lymphoblastic leukemia. (PubMed, Sci Adv)

We described a PAX5-driven enhancer at the CD58 locus, which was disrupted by PAX5 P80R, and the loss of CD58 abolished blinatumomab-induced T cell activation with global changes in transcriptomic/epigenomic program. In conclusion, we identified previously unidentified genetic mechanisms of blinatumomab resistance in B-ALL, suggesting strategies for genomics-guided treatment individualization.

Comprehensive Analysis of TP53 and CD58 Mutations and Identification of Patients with Inferior Prognosis and Enhanced Immune Escape in Diffuse Large B Cell Lymphoma (ASH 2022)

Our findings suggest that TP53 mutation alone is insufficient to effectively differentiate the risk of DLBCL. The mutually exclusive patterns between TP53 and CD58 mutations accurately stratified patients with DLBCL to permit the optional immunotherapy.

GENETIC AND EPIGENETIC FACTORS DRIVING PRIMARY MEDIASTINAL B-CELL LYMPHOMA PATHOGENESIS AND OUTCOME (EHA 2022)

Notably, DUSP2 mutated patients (25%) showed a similar outcome for CR rate, PFS and OS when comparing CHOP-like and intensified treatment regimens, suggesting no further benefit from treatment intensification in this very-low risk patient population. Conclusion Here, we present the genetic landscape of PMBCL highlighting a previously underappreciated role of chromatin modifying genes, identify novel treatment targets and provide a solid basis for guiding precision medicine approaches.

Detection of Aberrant CD58 Expression in a Wide Spectrum of Hodgkin and Non-Hodgkin Lymphomas: Implications for CAR T Cell Resistance (USCAP 2022)

We show that CD58 is lost in a significant proportion of all subtypes of lymphomas. As eligibility for CAR T therapy is being extended to a broader spectrum of lymphomas, mechanisms of resistance, such as CD58 loss, may limit therapeutic success. CD58 status is therefore an important biomarker in lymphoma patients who may benefit from next generation CARs with increased efficacy and other novel approaches that mitigate immune escape.
