  "textContent": "Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New research by immunologists in Germany is shedding light on how that amplification occurs in T cells, revealing a key molecular mechanism that helps trigger immune responses—and may also contribute to inflammatory conditions.",
