ABSTRACT
STUDY PURPOSE: The purpose of the study was to investigate the effect of age on the inflammatory response of peripheral, infiltrating monocytes after traumatic brain injury.
DATA COLLECTED: The dataset includes several experiments with mice using the parietal controlled cortical impact (CCI) TBI model. A summary of experiments are as follows: (1) Amount of infiltrating monocytes (CD11b+, CD45hi) in the injured brain of wildtype adult (3-4 mo) and aged (18+ mo) mice at 4 and 7 days post-injury (dpi) measured by flow cytommetry. (2) Amount of infiltrating monocyte (CD11b+, CCR2-rfp+) in the injured brain and in the blood of adult and aged (22-24 mo) CCR2-rfp-labeled mice at 4 and 7 dpi measured by flow cytommetry. (3) Amount of newly proliferated infiltrating monocytes (CD11b+, F4/80+, CD45hi) and resident microglia (CD11b+, F4/80+, CD45lo) in the injured brain labeled with BrdU between 3-4 dpi. (4) CCL2, CCL7, CCL8, and CCL12 quantified by qPCR from adult and aged animals at 4 and 7 dpi (normalized to young sham controls). (5) IL-1B, TNFa, iNOS, Ym1, CD206, TGF-B, and IL4Ra inflammatory marker expression measured by qPCR in wildtype adult and aged, Sham and TBI mice at 7 dpi. (6) Radial arm water maze behavior (errors; RAWM) measured at 26-28 dpi in wildtype and CCR2 knockout adult and aged (16-18 mo), Sham and TBI mice. (7) Amount of newly proliferated infiltrating monocytes (CCR2-rfp+) in the blood and bone marrow of adult and aged CCR2-rfp-labeled mice at 4 dpi using EdU labeling and flow cytometry.
