In this monocentric prospective study, the influence on long-term outcomes of peripheral blood levels of monocytic-myeloid-derived suppressive cells (M-MDSC) was investigated in 56 patients with acute leukemia (myeloid = 47; lymphoid = 9) before and after (Days+60/+90) allogeneic hematopoietic stem cell transplantation (Allo-HSCT). A risk of relapse was found to be associated with a level of pregraft M-MDSC above 1.4% by ROC curve analysis.

- Immunotherapy that uses the body's immune system is becoming popular in treating blood cancers like mantle cell lymphoma (MCL), but there's little understanding of immune cell behavior in MCL patients' lymph nodes and bone marrow.
- The study utilized a technique called RT-MLPA to analyze gene expression in MCL patients at diagnosis and relapse, focusing on immune-related genes to gain insights into tumor aggressiveness and immune response.
- Results showed that aggressive MCL forms had increased macrophage-related gene expression but lower T-cell markers, which could help differentiate between patient groups and guide personalized treatment approaches.
Immune effector cell-associated neurotoxicity syndrome (ICANS) is a frequent adverse event after Chimeric antigen receptor T cells (CAR-T cells). A patient treated with anti-CD19 CAR-T cells for a refractory mantle cell lymphoma presented at Day 8 post-infusion with extensive myelitis. Unusual eosinophilia was disclosed in the patient's cerebrospinal fluid.

Also, an anti-SARS-CoV-2 spike glycoprotein CD3+ T-cell response could be detected in six (35%) of 17 evaluable patients. This study provides a rationale to consider anti-SARS-CoV-2 vaccination of both recipients and donors before Allo-HSCT.

Antibody response to SARS-CoV-2 spike protein receptor-binding domain was tested at the time of the second injection (Roche Elecsys). The study also included a non-randomized control arm of 26 healthy controls.
