Fig 5

Healthy human volunteers were exposed to 30 minutes of intense light (10,000 Lux) at 8:30 AM on 5 consecutive days. A blood draw was performed before light exposure on the first day (8:30 AM) and 3 or 5 days after light exposure (9.00 AM). Plasma samples were analyzed using the SOMAscan platform. Shown are volcano pot analyses of the all light regulated proteins. Red arrows mark the strong effect of intense light on platelet factor 4 (PF4; n = 3 individual subjects, n = 12 of total samples/arrays).
