Core Tip

Core Tip: Immunological dysfunction-induced low-grade inflammation is regarded as one of the most important pathogenetic mechanisms in post-infectious irritable bowel syndrome. γδ T cells play a crucial role in innate and adaptive immunity. The adenosine molecule and receptors regulate intestinal inflammation and immunity. Through the PKA/CREB/NF-κB signaling pathway, we showed that adenosine 2A receptor contributes to the facilitation of post-infectious irritable bowel syndrome by T cells.
