The CML experience to elucidate the role of innate T-cells as effectors in the control of residual cancer cells and as potential targets for cancer therapy.

Front Immunol

December 2024

Université de Poitiers, Institut National de la Santé Et de la Recherche Médicale, Ischemie Reperfusion Métabolisme et Inflammation Stérile en Transplantation U1313, Poitiers, France.

Considering the general view that unconventional immune effectors play a major role in antitumor immunity, we recently postulated that the distinct new innate CD8 T-cell pool (co-expressing the transcription factor Eomesodermin and innate markers such as KIR/NKG2A) may counteract tumor cells, and thereby be potential target for cancer therapy. Here, to test this assumption, we used successfully targeted anti-leukemic therapy discontinuation (TFR) in chronic myeloid leukemia (CML). Numerical and functional status of innate CD8 T-cells, iNKT cells and γδ T-cells, in comparison with NK cells, was compared longitudinally between non-relapsed patients (i.

Fungal lung disease.

Eur Respir J

November 2024

Lee Kong Chian School of Medicine, Nanyang Technological University, Singapore, Singapore

Article Synopsis
  • Fungal lung disease includes various infections caused by fungi, particularly from the Aspergillus species, leading to conditions like allergic bronchopulmonary aspergillosis and chronic pulmonary aspergillosis, influenced by the patient's immune response and the type of fungi.
  • The diagnosis of these diseases is complicated by geographic and environmental factors as well as coexisting health issues, with new techniques developing but still facing challenges in speed and accuracy, especially in less developed areas.
  • Treatments mainly use antifungal drugs, but drug resistance is becoming a significant problem; however, new antifungal medications and better understanding of the lung mycobiome could pave the way for improved diagnosis and therapy.

September 2024

Virulence Bactérienne et Infections Chroniques, INSERM U1047, Univ Montpellier, Service de Microbiologie et Hygiène Hospitalière, Centre National de Reference des brucelloses, CHU Nîmes, Nîmes, France.

Introduction: Brucellosis, a zoonotic infectious disease caused by bacteria of the genus Brucella, remains a significant global health concern in many parts of the world. Traditional diagnostic methods, including serological tests, suffer from limitations, including low sensibility and high false-positive rates, emphasizing the need for improved diagnostic strategies. In this study, we aimed to optimize diagnostic accuracy by reevaluating serological tests and exploring novel diagnostic algorithms.

Article Synopsis
  • - The study focuses on the impact of Hepatocyte Nuclear Factor 1-beta (HNF1B) gene variants and chromosome 17q12 deletion (17q12del) on kidney disease progression, particularly chronic kidney disease (CKD), in a large cohort of 521 patients.
  • - Findings reveal that patients with the 17q12del experience a significant delay in the progression to CKD stage 3 compared to those with other HNF1B variants, with specific mutations in the DNA-binding domains correlating with even better outcomes.
  • - Additionally, the 17q12del is linked to lower magnesium levels (hypomagnesemia) and higher likelihood of elevated uric acid levels (hyperuric

The mechanisms underlying pain in cases of endometriosis or chronic pelvic pain are complex, often involving various types of pain; mainly nociceptive pain, central sensitization, and neuropathic pain. Our main objective was to examine the prevalence of neuropathic pain in women with symptomatic endometriosis, and secondary, to explore the factors associated with this type of pain and to assess the prevalence of a positive PPSC score and a history of sexual violence within this population. This study is a retrospective, comparative, single-center cohort study conducted from September 2019 to January 2023.

Article Synopsis
  • The study investigates allergic bronchopulmonary mycoses (ABPM) in patients with cystic fibrosis, focusing on specific IgE responses to five non-Aspergillus molds.
  • Researchers analyzed serum samples from 238 patients across several European countries, finding higher levels of specific IgE in these patients compared to healthy controls.
  • The findings highlight the need for improved diagnostic tools for ABPM, as several cases were identified using a new scoring system, emphasizing the importance of non-A. fumigatus molds in these conditions.

The ouroboros of autoimmunity.

Nat Immunol

May 2024

St. Giles Laboratory of Human Genetics of Infectious Diseases, Rockefeller Branch, New York, NY, USA.

Human autoimmunity against elements conferring protective immunity can be symbolized by the 'ouroboros', a snake eating its own tail. Underlying infection is autoimmunity against three immunological targets: neutrophils, complement and cytokines. Autoantibodies against neutrophils can cause peripheral neutropenia underlying mild pyogenic bacterial infections.

The epidemiology of invasive fungal infections in transplant recipients.

University of Angers, University of Brest, Infections Respiratoires Fongiques, SFR Interactions Cellulaires et Applications Thérapeutiques, Angers, France. Electronic address:

Transplant patients, including solid-organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients, are exposed to various types of complications, particularly rejection. To prevent these outcomes, transplant recipients commonly receive long-term immunosuppressive regimens that in turn make them more susceptible to a wide array of infectious diseases, notably those caused by opportunistic pathogens. Among these, invasive fungal infections (IFIs) remain a major cause of mortality and morbidity in both SOT and HSCT recipients.

Impact of climate change and natural disasters on fungal infections.

Lancet Microbe

June 2024

ECMM Excellence Center for Medical Mycology, Division of Internal Medicine, MD Anderson Cancer Center, University of Texas, Houston, TX, USA.

Article Synopsis
  • Climate change is making fungi stronger and better at surviving in warmer temperatures, which can lead to more fungal diseases.
  • As the climate changes, some fungi are spreading to new places where they didn't used to live, like cities and polluted areas.
  • People who are most affected by these changes are often those in weaker situations, so we need to pay more attention to this problem and get more funding and research to help.
