From: The role of the MAPK pathway alterations in GM-CSF modulated human neutrophil apoptosis with aging
Time-dependant activation of p38 MAPK following incubation with GM-CSF, effect of aging. Neutrophils were stimulated with GM-CSF from 0 to 18 hours and immediately lysed. Western-blotting experiments of neutrophils of young (A) and elderly subjects (B) lysates were conducted by revealing with anti-phospho-p38 MAPK polyclonal Abs. Control loading for p38 are shown under each blot. Blots are representative of 15 independent experiments.
