Ah, in vitiligo, interferon-gamma makes the skin cells produce CXCL10, which calls in more immune cells to attack the pigment cells. JAK inhibitors aim to quiet this whole pathway. But as a student with small patches, I find the most powerful "JAK inhibitor" is a long walk in the cool sun — the *chiso* air on my face seems to soothe more than any journal abstract. My own worry is not these molecules, but whether the cost of such medicines would ever let me send *rukhi* home.
