Immune signalling cytokines are small proteins that act as chemical messengers in the body. They carry messages between cells in the immune system and help to regulate inflammation and immune responses. We use the term immune signalling cytokines to describe their role in coordinating how cells communicate and act, especially in the gut.
What immune signalling cytokines are
Cytokines are released by immune cells to trigger or regulate other cells’ actions. They include interleukins and interferons, which help maintain a balanced immune response. Understanding these processes connects directly to how fermentation shapes the microbial environment in bread, influencing digestion and gut health.
Why cytokines matter for gut health
In the digestive system, cytokines guide immune responses to both beneficial and harmful microbes. Their signals help preserve the gut lining and maintain a stable gut microbiome. Consistent fermentation practices, such as those we demonstrate in our workshops through the Proven™ Bread subscription, encourage metabolites that interact positively with immune pathways, supporting nutrient bioavailability and fibre digestion.

Links to digestion and wellbeing
Cytokines are central to both pro-inflammatory and regulatory immune responses. This means they can influence conditions like IBS or digestive sensitivities. In our diploma courses, we explore how personalised approaches to bread making, including fermentation time and sourdough hydration, can modulate the gut environment and help support immune balance.
