The presence of serotonin-producing bacteria in the neonatal gut influences the balance of immune cells, fostering a healthy immune system.

Through analysis of neonatal mouse guts and human infant stool samples, researchers observed that serotonin production by gut bacteria plays a vital role in modulating immune cell populations, particularly T-regulatory cells (Tregs). Neurotransmitter Production In Early Development Contrary to previous beliefs that enterochromaffin cells generate serotonin, the study found that bacteria, abundant in neonatal guts, are the primary source of this neurotransmitter. The study reveals that newborns possess high levels of neurotransmitters, particularly serotonin, primarily produced by gut bacteria. This revelation ignites a new understanding of how these early microbial inhabitants sculpt the developing immune system, offering a shield against autoimmune diseases and allergic reactions to food a shield woven from the threads of serotonin and nurtured within the nurturing embrace of the gut microbiome. Contrary to conventional wisdom, it's not just the host's cells that contribute to serotonin synthesis but also a bustling community of bacteria nestled within the infant's gut. In a groundbreaking study published in Science Immunology, scientists have uncovered a pivotal role for gut bacteria in the production of serotonin during the neonatal stage. ![]() Weill Cornell Medicine researchers have delved into the depths of this microbial realm, unveiling a symbiotic bond between gut bacteria and the neurotransmitter serotonin, orchestrating a symphony of immune education crucial for early life. 1E).The gut acts as an overall caretaker of our body and mind, shaping not only our physical health but also our immune resilience.
