Persistent cytopenias after anti-BCMA CAR T-cell therapy are associated with reduced hematopoietic activity in posttreatment bone marrows.

Objectives: We attempt to analyze bone marrow findings and correlation with cytopenia(s) after anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell infusion in this study.

Methods: Relevant clinicopathologic data, including complete blood counts, neutrophil counts, relevant therapy history, and pre- and posttherapy bone marrow evaluations, were studied in 12 patients who received anti-BCMA CAR T-cell therapy.

Results: Bone marrow findings after CAR T-cell therapy were available in 6 of 12 cases, 3 of which showed markedly hypocellular marrow with either markedly reduced or essentially absent hematopoiesis.

Failure of CAR-T cell therapy in relapsed and refractory large cell lymphoma and multiple myeloma: An urgent unmet need.

Since its FDA approval, chimeric antigen receptor (CAR)-T cell therapy is changing the landscape of the treatment algorithm for relapsed and refractory large cell lymphoma and multiple myeloma. While initially hailed as a game changer and received widely with great enthusiasm, the reality of treatment failure soon became a major disappointment. This situation left patients and clinicians alike wondering about the next treatment options.

No needles needed: All-oral therapy options for relapsed and refractory multiple myeloma.

Immense progress has been made for the treatment of multiple myeloma over the past two decades, with patient outcomes improving dramatically as a result. Patient quality of life, however, is constantly challenged by complications of the disease, side effects of therapy and the overall burden receiving continuous treatment. Compared to parenteral agents, all-oral regimens can provide logistically favorable alternatives and are associated with improved quality of life.

Immunomodulatory drug- and proteasome inhibitor-backbone regimens in the treatment of relapsed multiple myeloma: an evidence-based review.

Introduction: Recent advances and drug approvals in the last decade have substantially changed the landscape of relapsed and refractory multiple myeloma (RRMM), which not only improved outcomes for patients but also increased complexity of treatment decisions. The approvals are based on randomized studies of novel agents added to an immunomodulatory drug- (IMiD) or proteasome inhibitor (PI)-backbone showing an improvement in outcomes. However, differences in enrolled patient populations/study designs limit comparisons of results, making the choice and sequencing of agents challenging.

The Human IL-22 Receptor Is Regulated through the Action of the Novel E3 Ligase Subunit FBXW12, Which Functions as an Epithelial Growth Suppressor.

Interleukin- (IL-) 22 signaling is protective in animal models of pneumonia and bacteremia by Klebsiella pneumoniae and mediates tissue recovery from influenza and Staph aureus infection. We recently described processing of mouse lung epithelial IL-22 receptor (IL-22R) by ubiquitination on the intracellular C-terminal. To identify cellular factors that regulate human IL-22R, we screened receptor abundance while overexpressing constituents of the ubiquitin system and identify that IL-22R can be shuttled for degradation by multiple previously uncharacterized F-box protein E3 ligase subunits.
