A complex chromosomal rearrangement observed in a patient with chronic myeloid leukemia was explained as the consequence of a multistep process. The explanation involved an initial t(9;22) translocation with breakpoints distant from the BCR and ABL1 genes followed by genomic deletions that produced the BCR-ABL1 hybrid gene. We present an alternative model that fits the origin of the patient's rearrangement better. The present model links submicroscopic inversions with the occurrence of the t(9;22) translocation and opens a new approach on the research on the disease.

Co-inhibitory molecules, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1), known as immune checkpoints, regulate the activity of T and myeloid cells during chronic viral infections and are well-established for their roles in cancer therapy. However, their involvement in chronic bacterial infections, particularly those caused by pathogens endemic to developing countries, such as Mycobacterium tuberculosis (Mtb), remains incompletely understood. Cytokine microenvironment determines the expression of co-inhibitory molecules in tuberculosis: Results indicate that the cytokine IL-12, in the presence of Mtb antigens, can enhance the expression of co-inhibitory molecules while preserving the effector and memory phenotypes of CD4+ T cells.

Despite the study of BCR::ABL1-positive and -negative myeloproliferative neoplasms (MPNs) providing seminal insights into cancer biology, tumor evolution and precision oncology over the past half century, significant challenges remain. MPNs are clonal hematopoietic stem cell-derived neoplasms with heterogenous clinical phenotypes and a clonal architecture which impacts the often-complex underlying genetics and microenvironment. The major driving molecular abnormalities have been well characterized, but debate on their role as disease-initiating molecular lesions continues.

The present study was aimed at revealing the metabolic changes that occurred in the cellular lipid pattern of acute and chronic myeloid leukaemia cells following treatment with cannabidiol (CBD). CBD is a non-psychoactive compound present in Cannabis sativa L., which has shown an antiproliferative action in these type of cancer cells.

Myeloid-derived suppressor cells (MDSCs) ameliorate inflammation by inhibiting T cell responses. In pathological conditions, such as autoimmunity, chronic infections or cancer they accumulate in the periphery. In cancer, MDSCs can also be part of the tumor microenvironment and are associated with a worse prognosis and limited response to immunotherapy.

Tyrosine kinase inhibitors (TKIs) targeting BCR::ABL1 are highly successful in chronic myeloid leukemia (CML). However, extensive interpatient variability in therapeutic responses and resistance supports the need to find new prognostic biomarkers. We have previously reported that TP53 SNP215 variant affects CML risk and clinical outcome.
