AI Article Synopsis

  • Adult T-cell leukemia (ATL) is a severe cancer linked to the HTLV-1 virus, with limited effective treatment options and poor prognosis.
  • Current treatments, such as antiviral therapies and monoclonal antibodies, show some responses but often fail to improve overall survival rates for patients.
  • Developing targeted therapies that focus on the HTLV-1 proteins and boosting the host's immune response presents a hopeful avenue for better treatment outcomes in ATL.

Article Abstract

Purpose Of The Review: Adult T-cell leukemia (ATL) is an aggressive chemo-resistant malignancy secondary to HTLV-1 retrovirus. Prognosis of ATL remains dismal. Herein, we emphasized on the current ATL treatment modalities and their drawbacks, and opened up on promising targeted therapies with special focus on the HTLV-1 regulatory proteins Tax and HBZ.

Recent Findings: Indolent ATL and a fraction of acute ATL exhibit long-term survival following antiviral treatment with zidovudine and interferon-alpha. Monoclonal antibodies such as mogamulizumab improved response rates, but with little effect on survival. Allogeneic hematopoietic cell transplantation results in long-term survival in one third of transplanted patients, alas only few patients are transplanted. Salvage therapy with lenalidomide in relapsed/refractory patients leads to prolonged survival in some of them. ATL remains an unmet medical need. Targeted therapies focusing on the HTLV-1 viral replication and/or viral regulatory proteins, as well as on the host antiviral immunity, represent a promising approach for the treatment of ATL.

Background: CD19 CAR T-cell therapy is a novel anti-cancer treatment that has produced remarkable responses in relapsed or refractory B-cell hematological malignancies. Cytokine Release Syndrome (CRS) is a dysregulated immune response that frequently occurs after CAR T-cell infusion. It can cause cardiac dysfunction and circulatory collapse negatively impacting outcomes and survival.

Background: Pancreatic adenocarcinoma (PDAC) exhibits a complex microenvironment with diverse cell populations influencing patient prognosis. Single-cell RNA sequencing (scRNA-seq) was used to identify prognosis-related cell types, and DNA methylation (DNAm)-based models were developed to predict outcomes based on their cellular characteristics.

Methods: We integrated scRNA-seq, bulk data, and clinical information to identify key cell populations associated with prognosis.

Sulfur mustard (SM) induced pulmonary disorder is a heterogeneous disease characterized by uncontrolled inflammatory immune responses. In this cross-sectional study carried out in Isfahan-Iran, our objective was to thoroughly evaluate the clinical health and peripheral blood leukocyte profiles of adult veterans exposed to SM 25-30 years. In total, 361 people were studied in two groups, 287 chemical veterans with pulmonary complications and 64 healthy individuals as a control group.

A unique inflammaging profile generated by T cells from people with obesity is metformin resistant.

The alarmingly high prevalence of obesity in older adults coupled with the negative health effects of chronic inflammation in both obesity and aging highlight the importance of studies investigating the impacts of obesity on age-related inflammation. Since shifts in peripheral T-cell metabolism and function drive systemic inflammation in both obesity and aging, we hypothesize that obesity impacts the Th17-dominated inflammaging profile we identified in lean subjects and thus modifies the anti-inflammatory effects of geroprotective drugs like metformin. New cytokine profiling data showed that CD4 T cells from older people with obesity generate a profile that specifically excludes Th17 cytokines.

Synovial sarcoma is an aggressive soft-tissue cancer that shows limited responses to current immunotherapeutic approaches using immune checkpoint blockade or adoptive cell therapy. To improve immunotherapy for this cancer, understanding how the immune cells in the tumor microenvironment associate with histological subtype, disease progression and current therapies is vital. To evaluate the immune infiltrate in synovial sarcoma in relation to histological subtype, disease progression and in response to cytotoxic treatment, we performed immunodetection of T cells, CD68 myeloid cells, endothelial cells and keratin on a series of 41 synovial sarcoma patients at various stages of disease.
