Renal CD169++ resident macrophages are crucial for protection against acute systemic candidiasisA renal CD169++ resident macrophage subpopulation controls Candida albicans growth, severe kidney inflammation, and immunopathology during acute systemic candidiasis.
Short-term IL-15 priming leaves a long-lasting signalling imprint in mouse NK cells independently of a metabolic switchNK cell reactivity is dynamically regulated by IL-15, and NK cells do not need more than a few minutes of exposure to remember the cytokine for several hours.
Profiling of immune dysfunction in COVID-19 patients allows early prediction of disease progressionDeep immune profiling of COVID-19 patients with different disease severity reveals populations associated with severe disease and can be used to predict disease severity early on.
Sustained Helicobacter pylori infection accelerates gastric dysplasia in a mouse modelHp infection was found to alter metaplasia and accelerate dysplasia in mice. Thus, Hp can promote gastric preneoplastic progression, in addition to its known role in initiating chronic inflammation.
Meningeal lymphoid structures are activated under acute and chronic spinal cord pathologiesWe found that acute insult to the central nervous system induces the formation of lymphocyte aggregates reminiscent of tertiary lymphoid structures within the spinal cord meninges. Unlike draining CNS-cervical lymph nodes, meningeal lymphocytes are locally activated during neuro-inflammtion and neurodegeneration.
Single-cell RNA sequencing of human breast tumour-infiltrating immune cells reveals a γδ T-cell subtype associated with good clinical outcomeSingle-cell sequencing of γδ-T cells from human blood and tumours revealed novel markers of subtypes with distinct effector functions and a subtype that is associated with favourable clinical outcome.
G-CSF shifts erythropoiesis from bone marrow into spleen in the setting of systemic inflammationGranulocyte colony-stimulating factor suppresses erythropoiesis of bone marrow and promotes splenic erythropoiesis during lipopolysaccharide-induced systemic inflammation in mice.
Interferon lambda 4 can directly activate human CD19+ B cells and CD8+ T cellsDirect effects of IFNλ4 on CD8+ T cells can link the IFNλ4 genotype to differential clearance of hepatitis C virus infections.
Leishmania-infected macrophages release extracellular vesicles that can promote lesion developmentMacrophages infected with Leishmania donovani release extracellular vesicles that are composed of parasite and host-derived molecules that have the potential to induce vascular changes in tissues.
Neurturin regulates the lung-resident macrophage inflammatory response to viral infectionThe neurotrophic factor RET is induced in lung macrophages by viral triggers and activation via its ligand neurturin regulates matrix proteins and cytokines that shape the inflammatory response.
