صحافة بلادي — A recent study has shown a new relationship between psychological state and the immune system, focusing on the role of Brunner’s glands in the intestine. These glands are located in the duodenum and influence gut bacteria and immune defenses.
The researchers conducted experiments on more than a thousand mice, stimulating or inhibiting the activity of the vagus nerve, which connects the brain to the intestines. The results showed that suppression of the central amygdala leads to decreased activity of Brunner’s glands and reduced mucus production, allowing harmful bacteria to multiply. In turn, activation of this amygdala promotes mucus production and supports the growth of beneficial bacteria.
It has also been noted that removing Brunner’s glands leads to a weakened immune system and an increased risk of infection. These findings highlight the importance of Brunner’s glands in maintaining gut health and the immune system, and illustrate how psychological factors can affect physical health.
