We report a rare case of T-cell acute lymphoblastic leukemia (T-ALL) with an aberrant phenotype. A 52-year-old man was admitted to our hospital because of lymph node (LN) swelling in the bilateral neck. A computed tomographic scan showed LN swelling in the mediastinum and a right pleural effusion. The tumor cells in the neck LN showed positivity for cytoplasmic CD3, CD7, CD19, and CD79a, whereas the tumor cells in the bone marrow (BM) showed positivity for CD10 and CD13 in addition to the former 4 antigens. The chromosomes in the BM were normal. Neither T-cell receptor gamma nor immunoglobulin heavy chain rearrangement was detected in the neck LN. We diagnosed this case as T-ALL with an aberrant phenotype and started the standard chemotherapy for ALL. The response was so effective that complete remission (CR) was easily attained. The patient is now under maintenance therapy in the first CR without hematopoietic cell transplantation.

Tissue-resident memory T cells (TRM) provide frontline protection against pathogens and emerging malignancies. Tumor-infiltrating lymphocytes (TIL) with TRM features are associated with improved clinical outcomes. However, the cellular interactions that program TRM differentiation and function are not well understood.

Current intensive treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has substantial side-effects, highlighting a need for novel biomarkers to improve risk stratification. Canonical biomarkers such as genetics and immunophenotype are largely not used in pediatric T-ALL stratification. This study aimed to validate the prognostic relevance of DNA methylation CpG island methylator phenotype (CIMP) risk stratification in two pediatric T-ALL patient cohorts: the Nordic NOPHO ALL2008 T-ALL study cohort (n=192) and the Dutch DCOG ALL-10/ALL-11 validation cohorts (n=156).

Patient-derived xenografts (PDXs) can be improved by implantation of a humanized niche. Nevertheless, the overall complexity of the current protocols, as well as the use of specific biomaterials and procedures, limits the wider adoption of this approach. Here, we identify the essential minimum steps required to create the humanized scaffolds and achieve successful acute myeloid leukemia (AML) engraftment.

Introduction: T cells are involved in the early identification and clearance of viral infections and also support the development of antibodies by B cells. This central role for T cells makes them a desirable target for assessing the immune response to SARS-CoV-2 infection.
Methods: Here, we combined two high-throughput immune profiling methods to create a quantitative picture of the T-cell response to SARS-CoV-2.

Craniocervical edema appears soon after chimeric antigen receptor T-cell (CAR-T) therapy in some cases. This phenomenon is often observed right after systemic cytokine release syndrome (CRS), and it is called local CRS (L-CRS). In severe cases, L-CRS causes airway obstruction and asphyxia, but it is not yet well known among hematologists.
