In 1914, Austria's Archduke Ferdinand was assassinated in Sarajevo. ![]() Future research will help determine how to manipulate PNS and CNS inflammatory responses in order to improve tissue repair and functional recovery. Rather than efficiently removing debris before resolving the inflammatory response as in other tissues, macrophages infiltrating the CNS exacerbate cell death and damage by releasing toxic pro-inflammatory mediators over an extended period of time. The efficacy of the PNS inflammatory response (although transient) stands in stark contrast with that of the CNS, where the response of nearby cells is associated with inhibitory scar formation, quiescence, and degeneration/apoptosis. Macrophages take over the bulk of phagocytosis within days of PNI, before exiting the nerve by the circulation once remyelination has occurred. Denervated Schwann cells respond to injury by shedding myelin, proliferating, phagocytosing debris, and releasing cytokines that recruit blood-borne monocytes/macrophages. The inflammatory response is initiated by axonal disintegration in the distal nerve stump: this causes blood-nerve barrier permeabilization and activates nearby Schwann cells and resident macrophages via receptors sensitive to tissue damage. In addition to requiring a robust regenerative response from the injured neuron itself, successful axon regeneration is dependent on the coordinated efforts of non-neuronal cells which release extracellular matrix molecules, cytokines, and growth factors that support axon regrowth. Therefore, studying PNI could be instructive for both improving PNS regeneration and recovery after CNS injury. In addition, the growth-supportive milieu of PNS axons is not sustained over time, precluding long-distance regeneration. ![]() Nevertheless, peripheral nervous system (PNS) axon regrowth is hampered by nerve gaps created by injury. In contrast with central nervous system (CNS) axons, those in the periphery have the remarkable ability to regenerate after injury. We then consider the initiation, progression, and resolution of the cellular inflammatory response after PNI, before comparing the PNI inflammatory response with that induced by spinal cord injury (SCI). The students responsible for the initial project were suspended by administration.In this review, we first provide a brief historical perspective, discussing how peripheral nerve injury (PNI) may have caused World War I. The teacher, having kept the poster displayed throughout multiple class periods, resigned days later, but multiple student reports to local media claimed the incident was not isolated, and only shed a glimpse into the racial harassment taking place throughout the student body. The poster board of concern depicted masks with Abrams's likeness with racial stereotypes including corn and banana decorations. In November 2018, a racist depiction of Stacey Abrams was shown during a student presentation during a math class at the school. The sheriff's office also concluded the pistol belonged to Andrea's parents and speculate a scenario where Miller shot Garrett before turning the gun on himself due to the weapon being found nearer his body. An investigation by the Carroll County Sheriff's Office pointed to an intended suicide plan with Central High students recalling Garrett speaking of suicide weeks before. Miller meanwhile was airlifted to Crawford Long Hospital in Atlanta. Garrett was taken to the nearby Tanner Medical Center where she was shortly pronounced dead. Students Andrea Garrett and Jeff Miller were found shot in a girls bathroom with a. On January 8, 1999, a suspected suicide pact shooting took place at the school.
