Researchers here report that life-long tristetraprolin (TTP) upregulation leads to reduced frailty and improved bone mineral density in aged mice. One of the functions of TTP is that it suppresses expression of the pro-inflammatory TNF-α cytokine, so a reduced degree of age-related inflammation would be the first place to look for an explanation of the outcome noted here. It is an open question as to whether TTP upregulation produces a more nuanced and reactive reduction of TNF-α signaling than is the case for the blunt, across the board inhibition achieved by present anti-TNF-α thera…
