Examples of the staining evaluation for interleukin-6 (IL-6; A + C) and glial fibrillary acidic protein (GFAP; B + D) for different survival times. A traumatic brain injury case with a survival time of 2.5 hours with minutely IL-6 immunopositivity in neurons (A) and some more GFAP-positive astrocytes (B) in the pericontusional zone. IL-6-positive staining in neurons and glial cells (C) and an astrogliosis containing numerous GFAP-positive astrocytes (D) surrounding a cortical contusion (not shown in the exemplified pictures) in a traumatic brain injury case with a survival time of 5 days.
