In vivo mouse models for adult brain tumors: Exploring tumorigenesis and advancing immunotherapy development.

Brain tumors, particularly glioblastoma (GBM), are devastating and challenging to treat, with a low 5-year survival rate of only 6.6%. Mouse models are established to understand tumorigenesis and develop new therapeutic strategies.

Direct Observation of a Single Peroneal Myotendinous Unit Anatomic Variant: A Case Report and Systematic Review.

Case: A 29-year-old woman with acute peroneal tendon subluxation underwent superior retinacular repair. On exposure, a single peroneal myotendinous unit was encountered, as opposed to the usual presence of independent peroneal tendons arising from separate muscle bellies. At 3-year follow-up, she has had no recurrence with full return to activity and no limitations.

Immunotherapy reverses glioma-driven dysfunction of immune system homeostasis.

Background: Glioma-induced immune dysregulation of the hematopoietic system has been described in a limited number of studies. In this study, our group further demonstrates that gliomas interrupt the cellular differentiation programming and outcomes of hematopoietic stem and progenitor cells (HSPCs) in the bone marrow. HSPCs from glioma-bearing mice are reprogrammed and driven towards expansion of myeloid lineage precursors and myeloid-derived suppressor cells (MDSCs) in secondary lymphoid organs.

The current landscape of immunotherapy for pediatric brain tumors.

Pediatric central nervous system tumors are the most common solid malignancies in childhood, and aggressive therapy often leads to long-term sequelae in survivors, making these tumors challenging to treat. Immunotherapy has revolutionized prospects for many cancer types in adults, but the intrinsic complexity of treating pediatric patients and the scarcity of clinical studies of children to inform effective approaches have hampered the development of effective immunotherapies in pediatric settings. Here, we review recent advances and ongoing challenges in pediatric brain cancer immunotherapy, as well as considerations for efficient clinical translation of efficacious immunotherapies into pediatric settings.

Therapeutic approaches targeting splicing factor mutations in myelodysplastic syndromes and acute myeloid leukemia.

Purpose Of Review: Mutations in components of the spliceosome are the most common acquired lesions in myelodysplastic syndromes (MDS) and are frequently identified in other myeloid malignancies with a high rate of progression to acute myeloid leukemia (AML) including chronic myelomonocytic leukemia and primary myelofibrosis. The only curative option for these disorders remains allogeneic stem-cell transplantation, which is associated with high morbidity and mortality in these patients. The purpose of this review is to highlight the recent therapeutic developments and strategies being pursued for clinical benefit in splicing factor mutant myeloid malignancies.
