New Study: Microbiome and Asthma


Today is WorldAsthmaDay so we are looking at this 2018 study, which explores the link between asthma and our gut microbiome. Studies show that dysbiosis (imbalance in our gut bacteria), especially in early life, is strongly associated with asthma risk and severity of symptoms. Restoring the microbiome with pre- and probiotics may improve the tolerance of our immune system to environmental triggers and reduce inflammation of the airways in asthma sufferers.

"Study Abstract

The mucosal immune system is in constant communication with the vast diversity of microbes present on body surfaces. The discovery of novel molecular mechanisms, which mediate host-microbe communication, have highlighted the important roles played by microbes in influencing mucosal immune responses. Dendritic cells, epithelial cells, ILCs, T regulatory cells, effector lymphocytes, NKT cells and B cells can all be influenced by the microbiome. Many of the mechanisms being described are bacterial strain- or metabolite-specific. Microbial dysbiosis in the gut and the lung is increasingly being associated with the incidence and severity of asthma. More accurate endotyping of patients with asthma may be assisted by further analysis of the composition and metabolic activity of an individual’s microbiome. In addition, the efficacy of specific therapeutics may be influenced by the microbiome and novel bacterial-based therapeutics should be considered in future clinical studies.
