Abstract

Since the inflammatory process develops after transplantation to the brain, we sought to determine the presence of cytokines following a surgical trauma to the brain of an adult mouse. We report the early and marked presence of tumor necrosis factor-α and interleukin-1α in neuronal somata of the striatum following a surgical injury to the hippocampus. The expression of cytokines later extends to neuronal cells of the hippocampus, thalamus, cerebral cortex, brain stem, and cerebellum and to glial cells of the corpus callosum. By contrast, these cytokines are not expressed by neuronal cells following injury to other regions, such as the striatum, cerebellum, and cortex. This study suggests a possible role for certain neurons in the brain's early reaction to a penetrating injury.

      This phenomenon has been termed “ischemic tolerance,” which is believed to trigger a great many intrinsic neuroprotective mechanisms, but the mechanisms have not been fully defined yet. Tumor necrosis factor-α (TNF-α), an important inflammatory factor, has been traditionally viewed as a mediator of disease pathogenesis in the central nervous system, including cerebral ischemia, Parkinson's disease, Alzheimer's disease and brain injury (Scherbel et al., 1999; Tchelingerian et al., 1993; Yin et al., 2003). For a long period of time, TNF-α had been believed to induce neuronal cell death, resulting in brain injury (Feuerstein et al., 1998), until Cheng et al. (1994) demonstrated that TNF-α pretreatment protected cultured neurons from glucose deprivation-induced injury and excitatory amino-acid toxicity.

      Therefore, it is possible that amygdalar expression of GFAP and Iba1 could significantly increase over time. Moreover, surgical lesions to the hippocampus induces IL-1β and TNF-α expression in the striatum, cortex and basal ganglia, which is not accompanied by the presence of reactive astrocytes and microglia in those brain regions [86]. Other studies not investigating whether or not activation of astrocytes and microglia takes place, have reported that cytokine signals propagate to brain regions far from the site where kainate was injected [87] or controlled cortical impact was delivered [88].

      TNF-α is a prototypic pro-inflammatory cytokine originally discovered in the innate immune system. TNF-α, together with their surface receptors, is also present in the central nervous system, and displays cellular, regional, spatial, and temporal specificity of expression and action (Boka et al., 1994; Breder et al., 1993; Churchill et al., 2008; Tchelingerian et al., 1993). Previous studies have implicated that TNF-α action is complex and can produce opposite effects, protective or noxious, under different conditions or contexts.
