Abstract
Recently, we reported on the activation of c-Jun N-terminal kinase (JNK) in primary glial cells noting certain differences in the patterns of kinase activation in astrocytes and oligodendrocytes (Zhang et al., J Neurosci Res 46:114–121;1996). In this extended study, we have examined the activation and expression levels of JNK1 and JNK2 isoforms in different glial cell types including the two in vitro-defined astroglial subtypes (type-1 and type-2), oligodendrocytes and microglia. An in-gel kinase assay of cell extracts and JNK-immunoprecipitates revealed the activation of both JNK1 and JNK2 in type-1 astrocytes in response to TNFα, and in microglia, in response to TNFα and bacterial lipopolysaccharide. The strong activation of the two JNK isoforms in type-1 astrocytes and microglia contrasted with a predominant activation of JNK1 over JNK2 in type-2 astrocytes and oligodendrocytes, the two glial subtypes sharing a common lineage. Immunoblot and immunocytochemical analyses using isoform-speciflc antibodies showed a differential expression of the two isoforms in different glial cells thereby accounting for their observed differential activation.
