  • 180. Intestinal Mycobiome | The Role That Beneficial Microbes Play in Regulating Pathogenic Fungal Species, Candida Overgrowth, & a Conversation on Mast Cell Activation Syndrome
    May 23 2025
    In this encore episode, we detail the intestinal mycobiome and the mechanisms by which beneficial microbes aid in regulating opportunistic fungal species: Candida albicans. We discuss Candida overgrowth virulence and how disruptions in microbial balance, immune function, and epithelial integrity impact Candida's pathogenicity. Additionally, we discuss the role of mast cells in the lamina propria, their involvement in mucosal immunity, and how Mast Cell Activation Syndrome (MCAS) can be exacerbated by fungal dysbiosis / microbial imbalances.Topics: 1. Introduction - The intestinal mycobiome and its role in intestinal health. - Regulating populations of opportunistic fungal species like Candida albicans.- Mast cell activation syndrome (MCAS) intro. 2. Structure of the Intestinal Barrier- The microbiome and mucus layer: microbes, mucins, antimicrobial peptides, sIgA.- The epithelial monolayer: enterocytes, goblet cells, Paneth cells, enteroendocrine cells…- Tight junction proteins and paracellular transport.- The lamina propria beneath the epithelium: immune cells and more. 3. Candida’s Pathogenicity and Barrier Disruption- Exists primarily in its yeast form, regulated by microbial competition, host immune defenses, antifungal peptides. - Secretory IgA (sIgA) and immune surveillance mechanisms help regulate fungal populations. - Chronic stress, immune suppression, and dysbiosis can deplete sIgA, increasing susceptibility to Candida proliferation. - Environmental triggers such as immune suppression, microbial depletion, inflammatory cytokines.- Yeast-to-hyphal transition, deeper tissue invasion. - Secreted aspartyl proteinases (SAPs), phospholipases, candidalysin: epithelial damage.- Pattern recognition receptors (PRRs) and overgrowth detection. 4. Impact of Beneficial Bacteria on Candida Overgrowth - Beneficial bacteria compete with Candida for nutrients and epithelial adhesion sites. - Short-chain fatty acids (SCFAs) produced by beneficial bacteria.- Depletion of beneficial bacteria removes ecological resistance, allowing Candida to proliferate unchecked. 5. Mast Cells in the Lamina Propria and Their Role in Intestinal Immunity- Mast cell location - Upon activation, mast cells release histamine, cytokines, proteases, and more that regulate gut immune responses. - Histamine can increase gut permeability and modulate local immune activation. - Tryptase and chymase. - Pro-inflammatory cytokines. 6. Mast Cell Activation Syndrome (MCAS) - Mast cell hyperactivation.- Environmental triggers, toxins, chronic infections, and stress. - Candida overgrowth and mast cell activation.- Addressing microbial imbalances and reducing the body’s total microbial, chemical, and toxin burden.- A diverse microbiome. 7. Conclusion- Candida overgrowth and regulation via immune defenses and beneficial bacterial competition.- MCAS, root cause approach.Get Chloe's Book Today!

H. pylori Overview- Gram-negative bacterium, can colonize the stomach lining- Many individuals remain asymptomatic- Symptoms - Can contribute to gastritis and peptic ulcers- Produces urease, hydrolyzes urea into ammonia (NH₃) andcarbon dioxide (CO₂)- Ammonia neutralizes stomach acid locally, protective microenvironment- H. pylori damages the mucosal barrier and contributes to persistence- Possesses additional virulence factors 3. Gastric Anatomy - Stomach is divided into the cardia, fundus, body, and pylorus- The gastric mucosa - The epithelial lining; mucous cells, parietal cells, chief cells, and more 4. Mucous Cells and Mucosal Protection - Line the gastric pits and secrete thick, viscous mucus- Mucus composed of water, mucin glycoproteins, and other low-molecular-weight molecules- Traps bicarbonate ions (HCO₃⁻)- Shields the stomach lining 5.

We discuss factors including dysautonomia, stress, microbial overgrowth, and more, with regards to potential effects upon gastrointestinal motility. We further detail symptoms of altered GI motility. Topics:1. Introduction to Gastrointestinal Motility- Orchestrated contraction of smooth muscles that propel contents along the digestive tract. - Roles in mixing, absorption, and preventing bacterial overgrowth.- Disruptions in motility. 2. The Enteric Nervous System (ENS) and Its Role- Myenteric and submucosal plexus.- Coordinating contractions and relaxations for effective motility. - Mucosa includes epithelium, lamina propria, and muscle. - Submucosa houses the submucosal plexus. - Muscularis externa. - Inner circular and outer longitudinal muscle layers with the myenteric plexus in between. 3. The Role of Interstitial Cells of Cajal (ICCs)- Specialized pacemaker cells in muscular layers - Generate slow-wave electrical activity to synchronize smooth muscle contractions - Critical for peristalsis.- Work with neural inputs to fine-tune gut motility 4. Dysautonomia and Its Impact on Gut Motility- Dysfunction of the autonomic nervous system (ANS) - Motility impacts- Microbial overgrowth, SIBO 5. Gastrointestinal Dysmotility- Neurological dysregulation - Structural abnormalities and smooth muscle dysfunction - Hormonal imbalances - Microbial overgrowth - Autoimmunity 6. The HPA Axis- Hypothalamus, pituitary gland, adrenal glands - Central to the stress response and interlinked with gut function - The amygdala and PVN of the hypothalamus - CRH stimulates ACTH, leading to cortisol release from adrenal glands 7. Cortisol and Gut Barrier Function- Cortisol is a glucocorticoid that modulates immune function and gut physiology - Chronic cortisol exposure can impair tight junction (TJ) integrity - Increases paracellular permeability and allows passage of antigens and endotoxins 8.Stress-Induced Changes in Gut Motility- Slow gastric motility - Increased colonic motility 9.
