Nectin-4 is a tumour-specific antigen that interacts selectively with the immune receptor TIGIT, resulting in inhibition of NK-cell cytotoxicity. We have explored the molecular and structural basis of this interaction and leveraged the information for structure-guided engineering of a TIGIT mutant exhibiting higher interaction affinity with nectin-4 and weaker binding to nectin-2 and PVR. The … Read more

To enable the analysis of B cell and T cell immune responses in mouse lymph nodes, spleen, and bone marrow, including different B cell and T cell subsets and their activation status, as well as the antigen-reactivity and isotype of B cells, a novel 31-parameter spectral flow cytometry panel was developed.

Thymic Stromal Lymphopoietin (TSLP) regulates the skin microenvironment during type 2 inflammation. Epidermal APCs, Langerhans cells (LCs), might be the target of TSLP, but whether LCs express CD127 needed for TSLP signaling has been unclear. We found that LCs express both receptor chains needed by TSLP (CD127 and TSLPR) and upregulate the TSLPR upon Calcipotriol … Read more

Current plasma cell–targeting therapies lack antigen specificity. Using an antibody-mediated cytotoxicity engager (ACE) targeting the α-subunit of the extracellular domain of the human acetylcholine receptor (hAChR αECD), we selectively depleted pathogenic antibody-secreting cells in a myasthenia gravis model, reducing autoantibody titers and disease severity while preserving nonspecific antibody-secreting cells and humoral immunity. ABSTRACT Myasthenia gravis … Read more

In a neonatal mouse model of E. coli sepsis, depleting neonatal neutrophilic cells (NNC) increased mortality and systemic inflammation. The bacterial load increased slightly, and the immune cell populations remained unchanged. These findings suggest that NNC may play a role in controlling inflammation and protecting neonates from lethal sepsis. ABSTRACT Neonates are particularly susceptible to … Read more

Lymphatic endothelial cells at the cribriform plate and in brain-draining cervical lymph nodes express PD-L1 during autoimmune encephalitis. Unexpectedly, deletion of lymphatic PD-L1 expression ameliorates disease symptoms and is associated with increased brain infiltration of regulatory CD8+ Foxp3+ T cells.

Anti-cN1A autoantibodies are helpful for diagnosing inclusion body myositis (IBM). We have developed an immunofluorescence assay based on the perinuclear accumulation of GFP-cN1A. The analysis of patient sera indicated that this assay shows a higher sensitivity for anti-cN1A in IBM compared to alternative assays, without loss of specificity.

A preclinical model of TLR7-agonist-induced psoriasis develops insulin resistance by 3 weeks. Development of this psoriasis-associated insulin resistance can be prevented by systemic blockade of type I interferon signaling. ABSTRACT Psoriasis is a cutaneous autoimmune disease with worldwide prevalence. In situ activation of skin-infiltrating plasmacytoid dendritic cells (pDCs) leading to local induction of type I … Read more

Irgm1 regulates inflammatory disease by modulating leukocyte responses including those of T cells. In CD4+ T cells, Irgm1 functions in a cell-intrinsic manner. However, in CD8+ T cells, Irgm1 restrains cytokine production and cell death in a cell-extrinsic manner by controlling type I interferon production from hematopoietic and other sources. ABSTRACT Immunity-related GTPases (IRGs) are … Read more

Long-COVID or post-acute sequelae of COVID-19 syndrome (PASC) patients with previous severe COVID-19 ICU history prior vaccination display sustained significant changes in their immune profile at both the cellular and the inflammatory level, revealing signatures of persistent inflammation and endothelial injury. ABSTRACT SARS-CoV-2 infection can lead to persistent symptoms (i.e., long/post-COVID), especially in unvaccinated individuals. … Read more
