Quick Update: New findings on gut health and covid-19 spike protein

I am sharing a quick update to my readers on a new study posted to the journal of Mucosal Immunity in August 2024. Here is an overview of the paper.


Overview:

The study described in the paper is an experimental study that primarily uses animal models (specifically, murine models, or mice) to investigate the effects of the SARS-CoV-2 Spike protein on the gastrointestinal tract. The researchers also employed in vitro experiments using human enterocytes (gut cells) to further explore the impact of the Spike protein on gut health. Additionally, the study involved molecular docking analyses to examine the interaction between the Spike protein and specific proteins involved in gut function.


The study investigates the effects of the SARS-CoV-2 Spike protein on the gastrointestinal (GI) tract, emphasising its impact on gut integrity and immune response. The research provides insight into the mechanisms underlying COVID-19-related gastrointestinal symptoms, such as diarrhoea, and presents an experimental model using murine jejunal loops to simulate these effects.


Key Findings:

  1. Intestinal Inflammation: The Spike protein induces significant inflammation in the murine jejunal loops, characterised by leukocyte infiltration, oedema, and increased levels of pro-inflammatory cytokines (e.g., IL-6, TNF-α). This inflammation disrupts the intestinal mucosal barrier, leading to impaired gut function.

  2. Gut Barrier Disruption: The study demonstrates that the Spike protein compromises the integrity of the intestinal mucosa. This includes alterations in the expression of tight junction proteins, leading to increased intestinal permeability and reduced transepithelial electrical resistance (TEER). These changes suggest a weakened barrier function, making the gut more susceptible to further damage and pathogen invasion.

  3. Paneth and Goblet Cells Impairment: The Spike protein causes degranulation of Paneth cells, leading to reduced levels of lysozyme, an important antimicrobial enzyme. It also diminishes mucin 2 (MUC2) expression in goblet cells, weakening the mucus layer that protects the intestinal epithelium.

  4. Electrolyte Imbalance and Diarrhoea: The Spike protein increases chloride ion secretion in the gut, which can contribute to secretory diarrhoea, a common symptom observed in COVID-19 patients. This electrolyte imbalance disrupts the homeostatic environment of the intestine.

  5. Molecular Mechanisms: Molecular docking studies suggest that the Spike protein interacts with chloride channels (CFTR and CaCC), potentially driving the secretory effects observed. This interaction could be a key factor in the development of COVID-19-associated diarrhoea



Clinical Relevance:

The findings underscore the potential of the SARS-CoV-2 Spike protein to cause significant GI tract impairment, extending the understanding of COVID-19's impact beyond respiratory symptoms. This study provides a robust model for investigating COVID-19-related GI dysfunctions and could aid in the development of targeted therapies to mitigate these effects.


Targeted Therapies:

Supporting gut health, especially in the context of viral or spike protein persistence, requires a holistic approach that integrates several key lifestyle interventions. The aim is to reduce or eliminate spike persistence, using targeted nutraceuticals and medications and promote the growth of beneficial gut bacteria and help maintain the integrity of the gut lining. Nutrition, sunlight, hydration, sleep, balancing circadian rhythms and some supplements and medications can help to support this. 


I encourage everyone to go back and review Dr Carols Brogna’s work on this area and review his intervention strategies at the onset of any new infection.


I am currently exploring the use of human milk oligosaccharides, humic acids, prebiotics, pectin’s and immunoglobulins as nutraceutical interventions and to restore gut function.  Watch this space for further updates on the research.
