title: The LT beta R signaling pathway.
abstract: The lymphotoxin-beta receptor (LTbetaR, TNFRSF3) signaling pathway activates gene transcription programs and cell death important in immune development and host defense. The TNF receptor associated factors (TRAF)-2, 3 and 5 function as adaptors linking LTbetaR signaling targets. Interestingly, TRAF deficient mice do not phenocopy mice deficient in components of the LTbetaR pathway, presenting a conundrum. Here, an update of our understanding and models of the LTbetaR signaling pathway are reviewed, with a focus on this conundrum.
