A structural, genetic and clinical comparison of CAR-T cells and CAR-NK cells: companions or competitors?

Front Immunol

October 2024

Université Paris Cité, Centre National de la Recherche Scientifique, Institut National de la Santé et de la Recherche Médicale, Unité des Technologies Chimiques et Biologiques pour la Santé (UTCBS), Paris, France.

In recent years, following the groundbreaking achievements of chimeric antigen receptor (CAR) T cell therapy in hematological cancers, and advancements in cell engineering technologies, the exploration of other immune cells has garnered significant attention. CAR-Therapy extended beyond T cells to include CAR natural killer (NK) cells and CAR-macrophages, which are firmly established in the clinical trial landscape. Less conventional immune cells are also making their way into the scene, such as CAR mucosal-associated invariant T (MAIT) cells.

The kappa free light chains index is an accurate diagnostic biomarker for paediatric multiple sclerosis.

Mult Scler

October 2024

Clinical Immunology Laboratory, Groupe Hospitalier Universitaire Paris Saclay, Hôpital Bicêtre, Assistance Publique-Hôpitaux de Paris, Le Kremlin-Bicêtre, France.

Background: Multiple sclerosis (MS) may occur before the age of 18. Differentiation between paediatric MS (PedMS) and other demyelinating syndromes (ODSs) is challenging. In adult with MS, the kappa free light chain (KFLC) index has proven to be a reliable marker of intrathecal Ig synthesis.

Evaluation of analytical performance of AQUIOS CL flow cytometer and method comparison with bead-based flow cytometry methods.

Clin Chem Lab Med

September 2024

Clinical Immunology Laboratory, Groupe Hospitalier Universitaire Paris Saclay, Hôpital Bicêtre, Assistance Publique-Hôpitaux de Paris, Le Kremlin-Bicêtre, France.

Objectives: Given that method validation is mandatory for compliance with the International Organization for Standardization (ISO) 15,189 standard requirements, we evaluated the analytical performance of the AQUIOS CL system (Beckman Coulter) and compared it with two bead-based flow cytometry (FCM) protocols (BD FACSCAntoII and Beckman Coulter DxFLEX). There are no comparative literature data on standardized protocols for counting lymphocyte subsets on the new-generation cytometer DxFLEX.

Methods: We evaluated the AQUIOS CL's performance with regard to accuracy, linearity and stability by using dedicated control cell samples and patient samples.

Functional diversity of NLRP3 gain-of-function mutants associated with CAPS autoinflammation.

J Exp Med

May 2024

CIRI, Centre International de Recherche en Infectiologie, Univ Lyon, Inserm, U1111, Université Claude Bernard Lyon 1, CNRS, UMR5308 , ENS de Lyon, Lyon, France.

Article Synopsis
  • NLRP3-associated autoinflammatory disease is a collection of genetic disorders caused by mutations that lead to increased activity of the NLRP3 protein, which complicates diagnosis despite effective treatments available.
  • The study explores 34 different NLRP3 mutations, illustrating their functional differences based on how they respond to various signals that activate them, and highlights their link to symptom severity and misdiagnosis.
  • Findings reveal critical areas in the NLRP3 protein that affect its activity and response to treatments, offering new perspectives on the disorder's variability and potential directions for improving diagnosis and therapy.

Vaccination Coverage and Risk Factors Associated With Incomplete Vaccination Among Children in Cambodia, Madagascar, and Senegal.

Open Forum Infect Dis

April 2023

Université Versailles Saint-Quentin-en-Yvelines, Université Paris-Saclay, Anti-infective Evasion and Pharmacoepidemiology Team, Centre de recherche en épidémiologie et santé des populations, Inserm, Montigny-le-Bretonneux, France.

Background: Vaccination reduces mortality from infectious disease, which is the leading cause of death in children under 5 and bears a particularly high burden in low- and middle-income countries. The Global Vaccine Action Plan (2011-2020) has set a target of 90% vaccine coverage for all vaccines included in national immunization programs by 2020. The objectives of this study were to estimate vaccine coverage among children in Madagascar, Cambodia, and Senegal and to identify the risk factors associated with incomplete vaccination.

Article Synopsis
  • The study investigates myelin oligodendrocyte glycoprotein-associated disease in children, which has a relapse rate of 40% and can lead to severe outcomes.
  • Researchers aimed to find a biomarker to predict relapses by measuring levels of myelin oligodendrocyte glycoprotein antibodies and neurofilament light chains in patients' blood.
  • Results showed that non-relapsing patients had significantly higher neurofilament light chain levels than controls, while the correlation between neurofilament light chains and antibody levels was strong in relapsing patients but weak in non-relapsing ones.

[Peripheral neuropathies during systemic diseases: Part II (vasculitis)].

Rev Med Interne

April 2023

Service de médecine interne et immunologie clinique, Groupe Hospitalier Universitaire Paris-Saclay, Hôpital Bicêtre, Université Paris-Saclay, Assistance Publique-Hôpitaux de Paris, Le Kremlin-Bicêtre, France. Electronic address:

Primary systemic vasculitides, mainly of the small and medium-sized vessels, are frequently associated with peripheral neuropathies. When the disease is already known, the appearance of a neuropathy should suggest a specific injury, especially when associated with other systemic manifestations. Conversely, when neuropathy is inaugural, close collaboration between neurologists and internists is necessary to reach a diagnosis.

Université Paris-Saclay, Assistance publique-Hôpitaux de Paris, service de médecine interne et immunologie clinique, groupe hospitalier universitaire Paris-Saclay, hôpital Bicêtre, Le Kremlin-Bicêtre, France. Electronic address:

Systemic diseases (connective disease, granulomatosis) may be associated with peripheral neuropathies. The diagnosis can be complex when the neuropathy is the presenting manifestation of the disease, requiring close collaboration between neurologists and internists. Conversely, when the systemic disease is already known, the main question remaining is its imputability in the neuropathy.

Article Synopsis
  • The study assesses the new i-TRACK chemiluminescent instrument for monitoring biological TNF inhibitors in patients, comparing its performance to traditional ELISA methods in gastroenterology.
  • Intra- and inter-run performance metrics were found to be satisfactory, with i-TRACK often yielding higher values for drug and antibody measurements compared to manual ELISA.
  • While i-TRACK shows potential for routine use due to its rapidity and usability, it is recommended to use the same assay consistently in patient follow-ups due to some discrepancies in quantitative results.

Renal involvement of lymphomas proven by kidney biopsy: report of 10 cases from a tertiary care center and comparison with the literature.

Int J Hematol

November 2022

Assistance Publique-Hôpitaux de Paris, Service de Médecine Interne et Immunologie Clinique, Groupe Hospitalier Universitaire Paris-Saclay, Hôpital Bicêtre, CHU de Bicêtre, 78, rue du Général Leclerc, 94275, Le Kremlin-Bicêtre cedex, France.

Lymphomas localized in the kidney are a rare entity that may be challenging to diagnose. We analyzed data from 10 patients with renal involvement of lymphoma diagnosed between 2009 and 2019 on fine needle biopsy from our tertiary center, and compared these with findings of 160 cases reported in the literature. Diffuse large B-cell lymphoma was the main histology subtype (40 and 38% in our sample and in the literature, respectively), followed by low-grade B-cell lymphomas, mostly from the marginal zone (MZ).

White adipose tissue (AT) contributes significantly to inflammation - especially in the context of obesity. Several of AT's intrinsic features favor its key role in local and systemic inflammation: (i) large distribution throughout the body, (ii) major endocrine activity, and (iii) presence of metabolic and immune cells in close proximity. In obesity, the concomitant pro-inflammatory signals produced by immune cells, adipocytes and adipose stem cells help to drive local inflammation in a vicious circle.
