Autoimmmune hepatitis

Terziroli Beretta-Piccoli, Benedetta ; Mieli Vergani, Giorgina ; Vergani, Diego

In: Cellular & molecular immunology, 2021, p. 19

Autoimmune hepatitis (AIH) is a T-cell mediated, inflammatory liver disease affecting all ages and characterized by female preponderance, elevated serum transaminase and immunoglobulin G levels, positive circulating autoantibodies, and presence of interface hepatitis at liver histology. AIH type 1, affecting both adults and children, is defined by positive anti- nuclear and/or antismooth muscle...

Salivary gland macrophages and tissue-resident CD8+ T cells cooperate for homeostatic organ surveillance

Stolp, Bettina ; Thelen, Flavian ; Ficht, Xenia ; Altenburger, Lukas M. ; Ruef, Nora ; Inavalli, V. V. G. Krishna ; Germann, Philipp ; Page, Nicolas ; Moalli, Federica ; Raimondi, Andrea ; Keyser, Kirsten A. ; Jafari, S.

It is well established that tissue macrophages and tissue-resident memory CD8+ T cells (TRM) play important roles for pathogen sensing and rapid protection of barrier tissues. In contrast, the mechanisms by which these two cell types cooperate for homeostatic organ surveillance after clearance of infections is poorly understood. Here, we used intravital imaging to show that TRM dynamically...

The atypical receptor CCRL2 (C-C Chemokine Receptor-Like 2) does not act as a decoy receptor in endothelial cells

Mazzotti, Chiara ; Gagliostro, Vincenzo ; Bosisio, Daniela ; Del Prete, Annalisa ; Tiberio, Laura ; Thelen, Marcus ; Sozzani, Silvano

In: Frontiers in immunology, 2017, vol. 8, p. 1233

C-C chemokine receptor-like 2 (CCRL2) is a non-signaling seven-transmembrane domain (7-TMD) receptor related to the atypical chemokine receptor (ACKR) family. ACKRs bind chemokines but do not activate G protein-dependent signaling or cell functions. ACKRs were shown to regulate immune functions in vivo by their ability to scavenge chemokines from the local environment. This study was ...
