It also mitigates excessive inflammation through the modulation of immune cells, promoting the activity of M2 macrophages and regulatory T cells.\n\nFurthermore, butyrate is thought to modulate intestinal receptor hypersensitivity, leading to reduced intraluminal pressure and improved peristaltic function.
