New article in Cell Reports: How Th2 cells control obesity

The adipose tissue homeostasis relies on the interplay between several regulatory lineages, such as ILC2, Th2, Treg, eosinophils and type 2 macrophages. Among them, ILC2 are numerically the dominant source of type 2 cytokines and are considered as major regulators of adiposity. Despite the overlap in immune effector molecules and sensitivity to alarmins (TSLP, IL-33) between ILC2 and resident memory Th2 lymphocytes, the role of the adaptive axis of type-2 immunity remains unclear. Kevin Englebert and colleagues from the group of Guillaume Oldenhove show that mice deficient for CD27, a member of the TNF receptor superfamily, are more resistant to obesity and associated disorders. A comparative analysis of the CD4 compartment of both strains revealed higher numbers of fat resident memory Th2 cells in the adipose tissue of CD27KO mice, which correlated with decreased PD-1-induced apoptosis. Our data point to a non-redundant role for Th2 lymphocytes in obesogenic conditions.

Highlights:
• CD27 upregulates PD-1 expression on fat-resident Th2 cells in an intrinsic manner
• PD-1 shifts the fate of Th2 toward activation-induced cell death
• CD27 deletion results in increased adaptive type 2 immunity in the adipose tissue
• The adaptive axis of type 2 immunity protects against obesity and associated disorders

New publication in Science Translational Medicine on the imprinting of monocytes by vaccine adjuvants

August 14th 2024 - 14:27

Most vaccines based on recombinant antigens rely on coadministration with an adjuvant to elicit a robust immune response. Although adjuvants are needed for many vaccines, it is less clear which adjuvant(s) should be paired with each immunogen. In this article, GSK and IMI researchers from the group of Fabienne Willems and Arnaud Marchant showed that an AS01-adjuvanted hepatitis B virus vaccine, which induces robust CD4+ T cell responses against the vaccine antigen, also elicited trained immunity in human recipients, which was not observed in an Alum-adjuvanted vaccine. These data demonstrate...

Guillem Sanchez Sanchez is selected as a finalist for the F.R.S.-FNRS best PhD thesis prize in Biomedical and Pharmaceutical Sciences

Guillem Sanchez Sanchez, from David Vermijlen's laboratory, defended his thesis in December 2023, entitled “Decoding early life γδ T cell ontogeny and their response to bacterial infection through the lens of single-cell transcriptomics”. Recently, Guillem was selected as one of three finalists for the F.R.S.-FNRS in Biomedical and Pharmaceutical Sciences. He will present his work together with the two other finalists at the end of October 2024 on the UCLouvain campus in Brussels.

New publication in Nature Communications: Invariant γδTCR natural killer-like effector T cells in the naked mole-rat

May 30th 2024 - 11:33

Naked mole-rats are long-lived rodents known to be resistant to the development of cancer, yet their immune system remains poorly explored. Now, in a study published in Nature Communications, Guillem Sanchez Sanchez from the team of David Vermijlen with collaborators from the University of Rochester and from IMGT identify natural killer-like effector γδ T cells that express a dominant γδ T cell receptor and may serve a role in tumour immunosurveillance.

New publication on Tumor-associated Neutrophils

January 10th 2024 - 08:32

Neutrophils are white blood cells essential to our innate defense against pathogens. They patrol the body for 1 or 2 days, then die and are replaced by new neutrophils.
Using genetically-engineered mouse models of lung cancer, several research groups, including Prof. Etienne Meylan's, have recently observed that neutrophils entering the tumor can have an increased lifespan compared to other neutrophils, a behaviour that endows them with tumor-supportive functions. Now, in a study published in EMBO Molecular Medicine, Etienne Meylan and his laboratory have identified the molecular mechanisms...
