Phage Therapy in Gastrointestinal Diseases

 

Abstract

Gastrointestinal tract microbiota plays a key role in the regulation of the pathogenesis of several gastrointestinal diseases. In particular, the viral fraction, composed essentially of bacteriophages, influences homeostasis by exerting a selective pressure on the bacterial communities living in the tract. Gastrointestinal inflammatory diseases are mainly induced by bacteria, and have risen due to the emergence of antibiotic resistant strains. In the lack of effective treatments, phage therapy has been proposed as a clinical alternative to restore intestinal eubiosis, thanks to its immunomodulatory and bactericidal effect against bacterial pathogens, such as Clostridioides difficile in ulcerative colitis and invasive adherent Escherichia coli in Crohn’s disease. In addition, genetically modified temperate phages could be used to suppress the transcription of bacterial virulence factors. In this review, we will highlight the latest advances in research in the field, as well as the clinical trials based on phage therapy in the area of gastroenterology.

Patrick Gut Environment

\ Keywords to use in further research, GALT, tight junction proteins, Mucin layer, microbiome in MECFS or Long Covid, Goblet cells.   It was great chatting with you the other day. I’ve put together this general overview, but as I mentioned, you’ll definitely want to do your own deeper research. This is a very complex, interactive environment, and you’ll naturally come across many different opinions about what’s happening. Most opinions tend to focus on single layers, but as I’ve discovered, these layers are highly interconnected and influence one another. I don’t want to oversimplify things, nor do I want to overcomplicate them. It takes time to truly understand the gut environment in its proper context. I’m also cautious about saying “do X and you’ll get Y,” because results are rarely that straightforward. When I introduce layered therapies, I look for subtle changes across a list of markers I track. That’s why I believe this should be approached with care and patience—though I’m ...

Gut environment

 OK let's go back over the scenario Somebody gets a gut bug that could be viral or bacterial and we're going to put in the context of either long COVID or MECFS Let's discuss what exactly happens of how the body begins to adapt to this insult p — let’s build this cleanly, structurally, and without drama. This is the core terrain‑mechanics model of what happens when someone gets a gut bug (viral or bacterial) and then develops a long‑tail condition like long COVID or ME/CFS . This is the architecture that explains why the system never fully resets . I’ll walk you through it in chronological order , layer by layer, so you can see exactly how the body adapts — and why those adaptations become the trap. ⭐ 1. The Initial Insult Terrain layer: immune activation, epithelial irritation, redox stress A viral or bacterial gut infection does three things immediately: damages epithelial cells strips mucin spikes inflammatory cytokines This creates: redox collapse increased permeabil...

Paneth Cells - guardians of the intestinal tract

  Click for the AI slideshow: https://sl.bing.net/hBioK3sTdDw From Google Gemini: Paneth Cells: The Guardians of the Gut Paneth cells are specialized epithelial cells found at the base of the intestinal crypts (small invaginations in the intestinal lining). They play a crucial role in maintaining the gut's health by acting as a first line of defense against harmful microorganisms. Key Functions: Antimicrobial Defense: Paneth cells produce and secrete a variety of antimicrobial peptides and proteins, such as lysozyme, defensins, and phospholipase A2. These substances help to kill bacteria, fungi, and other pathogens that may invade the intestinal tract. Regeneration of Intestinal Epithelium: Paneth cells contribute to the maintenance and regeneration of the intestinal lining by supporting the stem cells located nearby. Immune Regulation: These cells participate in regulating the immune response within the gut, helping to balance the body's reaction to both beneficial and ha...
