cytokine release syndrome

Cytokine release syndrome (CRS) is a condition where the immune system overreacts, releasing a flood of signaling proteins called cytokines. This excessive response can cause widespread inflammation, leading to symptoms like fever, fatigue, shortness of breath, and low blood pressure. CRS often occurs after certain treatments, such as immunotherapies for cancer or some infections. While it helps fight disease, an exaggerated response can damage healthy tissues and organs. Managing CRS involves controlling the immune response to prevent severe complications while still fighting the underlying illness.
