Gut microbes
Tiny organisms, including bacteria, that live in your digestive system and affect everything from your metabolism to your immune system.

Regulatory T cells (Tregs)
A type of immune cell that helps control the body's immune response, preventing excessive reactions that could cause damage.

Microbiota
The community of microorganisms (including bacteria, fungi, and viruses) that inhabit a particular environment, in this case, the human gut.

Inflammation
The body's response to injury or infection, marked by redness, warmth, swelling, and sometimes pain.

Fibrosis
The formation of excess fibrous connective tissue in an organ or tissue, often as a result of healing or repair process; essentially, scarring.

IL-17
A pro-inflammatory cytokine, which is a type of signaling molecule in the immune system that can contribute to inflammatory responses.
