Innate lymphoid cells (ILC) combine innate and adaptive immune functions and are part of the first line of defense against mucosal infections. ILC are set apart from adaptive lymphocytes by their independence on RAG genes and the resulting absence of specific antigen receptors. In this review, we will discuss the biology and function of intestinal ILC that express the nuclear hormone receptor R...
The gut epithelium prevents bacterial access to the host's tissues and coordinates a number of mucosal defenses. Here, we review function epithelial inflammasomes in infected host focus on their role defense against Salmonella Typhimurium. This pathogen employs flagella swim towards type III secretion system (TTSS) dock invade intestinal cells. Flagella TTSS components are recognized by canonic...
The nasal cavity is a primary checkpoint for the invasion of respiratory pathogens. Numerous pathogens, including SARS-CoV-2, S. pneumoniae, aureus, etc., can adhere/colonize lining to trigger an infection. Secretory IgA (sIgA) serves as first line immune defense against foreign sIgA facilitates clearance pathogenic microbes by intercepting their access epithelial receptors and mucus entrapment...
The duodenum is the first segment of the small intestine, just distal to the gastric pylorus. This positions the epithelial lining of the duodenum directly in the path of destructive gastric acid leaving the stomach. Because pancreatic bicarbonate secretions only enter the gut lumen farther down the gastrointestinal tract, the early duodenum must defend itself, unaided, from this acidic stress....
Commensal microflora (normal microflora, indigenous microbiota) consists of those micro-organisms, which are present on body surfaces covered by epithelial cells and are exposed to the external environment (gastrointestinal and respiratory tract, vagina, skin, etc.). The number of bacteria colonising mucosal and skin surfaces exceeds the number of cells forming human body. Commensal bacteria co...
BACKGROUND & AIMS Interactions between mucosal cell types, environmental stressors, and intestinal microbiota contribute to pathogenesis in inflammatory bowel disease (IBD). Here, we applied metaproteomics of the mucosal-luminal interface to study the disease-related biology of the human colonic mucosa. METHODS We recruited a discovery cohort of 51 IBD and non-IBD subjects endoscopically samp...
