Long COVID patients consistently show: 13 Persistent gut dysbiosis with reduced microbial diversity lasting months after infection Depletion of butyrate-producing bacteria leading to reduced SCFA production and impaired immune regulation SARS-CoV-2mediated ACE2 downregulation disrupting renin-angiotensin system (RAS) balance and gut microbial homeostasis Increased intestinal permeability allowing endotoxin (LPS) translocation and systemic cytokine activation Gutorgan axis disruption contributing to respiratory, neurologic, cardiovascular, renal, and musculoskeletal symptoms Some studies have identified persistent viral RNA in gut tissue, suggesting the gastrointestinal tract may serve as a viral reservoir
It may be transient, recurrent or persistent and is characterized by its color, red
To further compare GSH synthetic capacities of different pathways, GSH1 gene of engineered strain W303-1b/F was deleted to eliminate synthesis of GSH by endogenous enzymes
