Chronic viral infections persistently alter marrow stroma and impair hematopoietic stem cell fitness.

The Journal of experimental medicine

Isringhausen S, Mun Y, Kovtonyuk L, Kräutler NJ, Suessbier U, Gomariz A, Spaltro G, Helbling PM, Wong HC, Nagasawa T, Manz MG, Oxenius A, Nombela-Arrieta C.
PMID: 34709350
J Exp Med. 2021 Dec 06;218(12). doi: 10.1084/jem.20192070. Epub 2021 Oct 28.

Chronic viral infections are associated with hematopoietic suppression, bone marrow (BM) failure, and hematopoietic stem cell (HSC) exhaustion. However, how persistent viral challenge and inflammatory responses target BM tissues and perturb hematopoietic competence remains poorly understood. Here, we combine...

Cytomegalovirus restricts ICOSL expression on antigen-presenting cells disabling T cell co-stimulation and contributing to immune evasion.

Angulo G, Zeleznjak J, Martínez-Vicente P, Puñet-Ortiz J, Hengel H, Messerle M, Oxenius A, Jonjic S, Krmpotić A, Engel P, Angulo A.

Elife. 2021 Jan 18;10. doi: 10.7554/eLife.59350.

Viral infections are controlled, and very often cleared, by activated T lymphocytes. The inducible co-stimulator (ICOS) mediates its functions by binding to its ligand ICOSL, enhancing T-cell activation and optimal germinal center (GC) formation. Here, we show that ICOSL...

CD4 T Cell-Mediated Immune Control of Cytomegalovirus Infection in Murine Salivary Glands.

Pathogens (Basel, Switzerland)

Zangger N, Oderbolz J, Oxenius A.
PMID: 34959486
Pathogens. 2021 Nov 23;10(12). doi: 10.3390/pathogens10121531.

CD4 T cells are well known for their supportive role in CD8 T cell and B cell responses during viral infection. However, during murine cytomegalovirus (MCMV) infection in the salivary glands (SGs), CD4 T cells exhibit direct antiviral effector...

Profiling the specificity of clonally expanded plasma cells during chronic viral infection by single-cell analysis.

European journal of immunology

Neumeier D, Pedrioli A, Genovese A, Sandu I, Ehling R, Hong KL, Papadopoulou C, Agrafiotis A, Kuhn R, Shlesinger D, Robbiani D, Han J, Hauri L, Csepregi L, Greiff V, Merkler D, Reddy ST, Oxenius A, Yermanos A.
PMID: 34727578
Eur J Immunol. 2021 Nov 02; doi: 10.1002/eji.202149331. Epub 2021 Nov 02.

Plasma cells and their secreted antibodies play a central role in the long-term protection against chronic viral infection. However, due to experimental limitations, a comprehensive description of linked genotypic, phenotypic, and antibody repertoire features of plasma cells (gene expression,...
