Function for NF-kB in neuronal survival: regulation by atypical protein kinase C

Activation of the transcription factor nuclear factor kappa B (NF-kB) has been intensely studied in the past several years due to its role as an inducible regulator of inflammation, apoptosis, transformation, and oncogenesis. Recently, increasing evidence supports a role for NF-kB in regulation of anti-apoptotic gene expression and promotion of cell survival (May and Ghosh [1999] Science 284:272-273). Studies in the past 5 years have provided evidence that NF-kB regulates neuronal survival as well. Moreover, atypical protein kinase (aPKC) has been shown to play a novel role in modulating the NF-kB pathway. In this review, I focus on neurons and the factors that contribute to regulation of NF-kB via aPKC.
