Amyotrophic Inhibitors,research,lifescience,medical lateral sclerosis (ALS) is heterogeneous Inhibitors,research,lifescience,medical in phenotype and genotype, and despite intense research effort, the underlying cause(s) remain obscure. Sporadic and familial forms

of ALS share common pathophysiological features, including a marked neuroinflammatory response, characterized by glial activation and innate and adaptive inflammatory components (for reviews, see Ilieva et al. 2009 and Appel et al. 2011). In murine models of ALS, activated astrocytes and microglia are observed in neuroinflammatory foci in the spinal cord prior to onset of symptoms, and such areas correlate with pronounced regional motor neuron loss (Shibata et al. 1996). Infiltration of CD8+ T-suppressor/cytotoxic and CD4+ T helper Inhibitors,research,lifescience,medical cells is also prominent (Kawamata et al. 1992). These cells alter disease progression both independently and through apparent cross-talk with microglia (Kipnis et al. 2004; Beers et al. 2008). Generally, glia secrete soluble factors that may be toxic (reactive oxygen species, proinflammatory cytokines) or protective (growth factors), however depending on local environment (Li et al. 2007). However, in models of ALS, transgenic expression of mutant hSOD1 in astrocytes and microglia results in glial phenotypes that are inherently neurotoxic compared to their wild-type counterparts (Boillee et al. 2006; Nagai et al. 2007). Thus, chronic neurodegeneration in ALS may evolve as a so-called noncell-autonomous process (Lobsiger and Cleveland 2007) that, in part, reflects a toxic glial microenvironment.
