Researchers have discovered a new drug that targets the mTOR pathway, which is involved in aging and metabolism. It could function as a caloric restriction mimetic, bringing about similar health benefits. The mTOR pathway The mechanistic target of rapamycin (mTOR) pathway is a part of metabolism and is one of the four major pathways that…

Rapamycin is a promising anti-aging therapeutic derived from a bacterium that was first found on Easter Island (it’s named for Rapa Nui, the official name of Easter Island). It inhibits mTOR (mechanistic target of rapamycin), thus inhibiting the immune system response that would, in some cases, lead to organ rejection. This is the on-label, FDA-approved…

Last year, resTORbio announced the positive results of its phase 2b human trial, which targeted the aging immune system with an immune system-boosting drug. Now, the company has announced the news that its therapy is moving to a phase 3 study later this year after successful negotiation with the FDA. Targeting the mTOR pathway of…

Researchers have discovered a link between the cellular recycling system known as autophagy and the behavior of microglial immune cells during aging. We have discussed the polarization of macrophages in a number of previous articles, and it has become quite a hot topic among researchers in the last few years. Microglia are tissue-resident macrophages in…

A new study takes a look at the relationship between metabolism, aging, and type 2 diabetes and in particular the mTORC1 protein complex, part of the mTOR pathway. The mTOR pathway The mechanistic target of rapamycin (mTOR) pathway is a major part of metabolism and is one of four major pathways that control it; collectively,…

Today, we are pleased to announce that the results are in from a human trial that targets the aging immune system and that an immune system-boosting drug appears to be effective. Targeting TORC1 to boost the immune system As we age, the immune system becomes increasingly poor and unable to detect and fight infections. This…

In a recent study conducted by researchers at the Novartis Institutes for Biomedical Research in Massachusetts, inhibition of mTOR complex 1 boosts the immune system of aged people, decreasing their yearly rate of infections as well as increasing their response to an influenza vaccine [1]. Study summary Inhibition of the mechanistic target of rapamycin (mTOR)…

Caloric restriction has long been known to increase the lifespan and healthspan of most studied animals. Research also shows that animals given a calorie-restricted diet are also generally more able to regenerate tissue damage following injury. Caloric restriction improves tissue regeneration A new study by the Lengner lab at the University of Pennsylvania has identified…
