ABSTRACT Pseudomonas aeruginosa (P.aeruginosa) is a pathogenic opportunistic bacterium, classified as a priority by the WHO for the research of new treatments. As this bacterium is harmful through the inflammation and tissue damage it causes, we investigated the role of Myeloid Derived Suppressor Cells … Read more

The commensal segmented filamentous bacteria (SFB) are crucial for orchestrating the post-natal maturation of the host gut immune system and establishing a healthy state of physiological inflammation, which largely depends on their intimate attachment to … Read more

ABSTRACT Inflammatory Bowel Disease (IBD) features en masse neutrophil (PMN) infiltration of the colon tissue, where PMNs occupy spatially distinct niches, including the lamina propria mucosa (LPNs) and the crypt epithelium (epithelium-associated neutrophils or EANs). Spatial PMN localization is currently used as a clinical … Read more

An increased understanding of how female sex hormones influence key pathophysiological processes that underpin asthma may identify new, more effective asthma therapies, particularly for females with severe, poorly controlled asthma. We assessed the effects of oral ethinylestradiol/levonorgestrel … Read more

ABSTRACT Autoimmune uveitis (AIU) is an immune-inflammatory disease that can lead to blindness. However, incomplete understanding of the involved immune cell subsets and their contributions to retinal injury has hindered the development of effective AIU therapies. Using single-cell RNA sequencing and immunofluorescence, we identified … Read more

ABSTRACT Emerging evidence indicates that gingival-resident helper CD4+ T cells are major drivers of periodontal inflammation in response to commensal and pathogenic oral microorganisms. Whether tissue-resident memory CD8+ T cells (TRM), which principally safeguard against viruses and cancer but also drive certain autoimmune and … Read more

ABSTRACT Interleukin-10 (IL-10) is an immunomodulatory cytokine critical for intestinal immune homeostasis. IL-10 is produced by various immune cells but IL-10 receptor signaling in intestinal CX3CR1+ mononuclear phagocytes is necessary to prevent spontaneous colitis in mice. Here, we utilized fluorescent protein reporters and cell-specific … Read more

ABSTRACT Lung-resident memory T cells (lung TRMs) settle in the lung and respond rapidly to external antigens, and are therefore considered to have great potential for development of respiratory vaccines. Here, we demonstrate that lung-resident memory Th2 cells (lung TRM2) protect against pulmonary mycosis … Read more

ABSTRACT Recently, we demonstrated that influenza A virus (IAV)-infected murine neonates lacking a functional IFN-I receptor (IFNAR-/-) had significantly improved survival and reduced lung pathology relative to wild-type (WT) neonates. In direct contrast, adult IFNAR-/- mice display enhanced morbidity following IAV infection relative to … Read more

ABSTRACT Influenza virus infection is a leading cause of morbidity and mortality worldwide, posing a significant public health problem. The pro-inflammatory cytokine interleukin-6 (IL-6) has been shown to promote defense against respiratory viral infection, while excessive IL-6 responses have been associated with severe pneumonia. … Read more
