The protozoan Tritrichomonas musculis (T. Mu) is a newly discovered gut microbe that facilitates communication between the gut and lung, according to University of Toronto researchers.

This strain of gut microbe in the lung immune environment, has both beneficial and detrimental effects on our respiratory health, adds the December 19 2025 Medical Express report.

 

University of Toronto researchers found T. mu managed immune changes in the lung, which worsened airway inflammation caused by T. mu but appears to protects against respiratory infections.

 

Kyle Burrows of Simon Fraser University and molecular geneticist Dr. Jun Liu of U. Toronto working together found that T. mu-colonized in mice served as an antimicrobial shield in the airways, helping to contain tuberculosis infections, according to the Medical Express report.

 

Melatonin plays a crucial role in regulating sleep through circadian rhythm modulation in humans and animals. Beyond its association with the pineal gland, it affects multiple organ systems, such as the gut-brain axis. 

 

The November 27 2024 report in Nature, suggests melatonin may be a therapeutic agent for various dysbiosis-associated conditions due to how it affects the intestinal microbiota.

 

What happens during the dark periods of winter?

Apparently a particular strain of gut bacteria aids in the production of melatonin, especially during the winter months.

 

A few bacteria and fungi also have been shown to synthesize melatonin, first discovered in 1995 with R. rubrum, an organism estimated to be 2 to 3.5 billion years old, and Porphyrobacter (formerly Erythrobacter) longus. These bacteria produce significantly more melatonin during extended periods of darkness compared with light periods.

 

 

 

 

JostArriba is now 100% compostable!

Our packaging is made from plant-based materials—cassava, wood pulp, and beetroot—that protect product quality while being completely compostable.

Researchers from Bar-Ilan University (BIU) led by Professor Omry Koren, from BIU’s Azrieli Faculty of Medicine in Israel have found that a disrupted gut microbiome due to antibiotic use in infancy can lead to aggression later on, causing changes to aggression-related genes, according to a recent September 23 2024 report in New Atlas. Said Professor Omry Koren, “disrupted microbiome during critical developmental periods can lead to persistent aggressive behaviors later in life.”

 

Aggression is a complex social behavior associated with survival modulated aggression, including by specific genes, neurotransmitters, environmental factors, and hormones especially Serotonin which is produced in our gut, according to New Atlas.
