Can diet alter the expression of a bacterial antigen to change adaptive immune responses? According to a new research conducted by M.M. Wegorzewska and her team on a mouse model, yes, it can. This research was not the first of its kind that suggested that microbes interact with the host immune system via several potential mechanisms. One step is the method by which intestinal microbes or their antigens access specific host immune cells. But what are immune cells and what is their role?
All disease is interconnected to the body’s T cells, which are sometimes too high and sometimes too low. T cells are the body’s immunity. They are defence–either the killer T cells that fight off invading bacteria or the helper T cells that repair and keep us healthy 24 hours a day.
T cells are produced in our thymus gland, and every second, 2-3 million red blood cells (RBC) are produced in the bone marrow and released into the circulation; our RBC last between 3 to 4 months. The thymus gland is constantly busy in maintaining and replacing T cells for optimal health. The treatment for intestinal diseases, such as colitis and maybe Crohn’s disease, could be linked to the interaction between the right bacteria culture and how it stimulates the production of T cells.
Now a new experiment investigates how the microbiome shapes immunity. Researchers wanted to know “whether B. theta (Bacteroides thetaiotaomicron), which is known to change its gene expression to break down different available foods, produces more or less of the key antigen depending on its energy source—and whether this, in turn, affects T cells response.”
The interesting discovery was the connection between how glucose or sugar-spiked water influenced the production of B. theta bacteria and how it dramatically lowered the T cell–interacting antigen, activating fewer cytokine-producing T cells, which can spark an immune response in the colon and its lymph nodes. So “commensal intestinal bacteria respond to dietary changes by modifying gene expression, leading to shifts in the levels of bacterial antigens encountered by the intestinal immune system. These findings suggest that dietary modifications that reduce expression of immunodominant antigens targeted by T cells could help ameliorate some forms of human inflammatory bowel disease.”
In the meantime, the best preventive measure is to maintain our healthy gut bacteria with a balanced probiotic complex–a healthy mix of several bacteria from human strain such as Lactobacillus rhamnosus, Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium longum, and if shelf-stable, the prebiotic should be inulin.
For this reason, Laktokhan Probiotic Complex would be an ideal choice. Our Laktokhan contains 10 billion CFU (colony-forming units) of four human strains of “friendly” intestinal microflora mentioned above. These friendly bacteria help keep harmful bacteria from multiplying in our intestines. Antibiotics can kill off healthy bacteria and lead to weakened immunity and intestinal disorders. Laktokhan restores the balance of good bacteria, thus helping to normalize digestive function and boost immunity. The positive cellular and molecular effects performed by natural products like Laktokhan have been described in several studies and proven by users.
In addition, you can monitor your glucose/sugar levels and to keep your T cells healthy by supplementing with Thymus Gland—in this day and age our gut micro bacteria needs all the help it can get. Meanwhile, don’t forget about the fact that healthy diet is crucial, as well as healthy sleep patterns, adequate water intake, exercise, and our mental well-being. Remember, health is a complex state that requires a complex care.
