Witryna25 kwi 2024 · Homeostasis is an organism’s process of maintaining a stable internal environment suitable for sustaining life. The word homeostasis derives from Greek, homeo meaning “similar,” and stasis, meaning “stable.” ... Thankfully, the human immune system – lymph nodes, enzymes, t-cells, and b-cells – protects your body … WitrynaMoreover, innate immune cells serve as a bridge between the microbiota, epithelium, and the adaptive immune system, parlaying tonic microbial stimulation into signals critical for mucosal homeostasis. Dysregulation of gut homeostasis and the subsequent disruption of tolerance therefore have c...
