p50 NF-?B and Dendritic Cells: a matter of life and death Paola Larghi, Chiara Porta and Antonio Sica

Already 10 years ago, p50, a regulatory subunit of the NF-?B family of transcription factors was shown to accumulate in the nucleus of LPS tolerant cells. More recently, the group of Antonio Sica has shown that accumulation of p50 homodimers in the nucleus of Tumour Associated Macrophages results in defective expression of proinflammatory cytokines (TNF-?, IL-12) and reduced IL-10 production, correlating with increased tumour growth. Moreover, p50 accumulation in the nucleus of macrophages is an essential event for promoting endotoxin tolerance and pro-tumour polarized functions in these cells. Given the important role of p50 in controlling tolerance in innate immunity (macrophages), we wondered if p50 accumulation in Dendriic Cells could mediate their activation versus tolerant activity over adaptive immunity.
