[Immune responses and neuroimmune modulation in the pathogenesis of acute ischemic stroke and poststroke infections].
Acute-onset cerebrovascular diseases are connected to a number of immunological changes. Here, we summarize immune responses participating in the evolution of atherosclerotic plaques and poststroke local immune responses in the injured CNS as well as in the systemic circulation. Ischemic injury of the CNS alters the balanced neuroimmune modulation resulting in CIDS, the central nervous system injury-induced immune deficiency syndrome. Due to the immunodepression and reduced pro-inflammatory immune responses, the susceptibility for infection is increased; indeed, poststroke infection plays a major role in stroke-related mortality. On the other hand, CIDS may protect against damaging autoimmune responses elicited by exposed CNS antigens. Investigation of immune responses related to ischemic stroke may result in novel therapies indicated by an increasing number of experimental and clinical trials altering poststroke immune responses and preventing infections.
