There is increasing recognition that reactive astrocytes are vital and central responders to CNS injury and disease, but there is no widely accepted definition of reactive astrogliosis.
WebInfection leads to extended reactive gliosis and destruction of infected cells in regeneration-incompetent organisms, restricting the spread of infection. In regeneration-competent organisms, however, limited gliosis and rapid regeneration can lead to intra-CNS spread of infection. For clarity, macroglia are shown as astroglial-like rather than ...
