Abstract:
The mammalian target of rapamycin (mTOR) represents a critical hub for the regulation of different processes in both normal and tumor cells. Furthermore, it is now well established the role of mTOR in integrating and shaping different environmental paracrine and autocrine stimuli in tumor microenvironment (TME) constituents. Recently, further efforts have been employed to understand how the mTOR signal transduction mechanisms modulate the sensitivity and resistance to targeted therapies, also for its involvement of mTOR also in modulating angiogenesis and tumor immunity. Indeed, interest in mTOR targeting was increased to improve immune response against cancer and to develop new long-term efficacy strategies, as demonstrated by clinical success of mTOR and immune checkpoint inhibitor combinations. In this chapter, we will describe the role of mTOR in modulating TME elements and the implication in its targeting as a great promise in clinical trials.
Insights
The mammalian target of rapamycin (mTOR) pathway regulates normal and tumor cell processes. Targeting mTOR shows promise for improving anti-cancer immune responses and long-term efficacy.
Area of Science:
- Oncology
- Cell Biology
- Immunology
Background:
- The mammalian target of rapamycin (mTOR) is a key regulator in normal and cancer cells.
- mTOR integrates environmental signals within the tumor microenvironment (TME).
Purpose of the Study:
- To elucidate the role of mTOR in modulating TME components.
- To explore the implications of targeting mTOR for cancer therapy.
Main Methods:
- Review of current literature on mTOR signaling in cancer.
- Analysis of mTOR's involvement in angiogenesis and tumor immunity.
- Examination of clinical trial data for mTOR inhibitors and combination therapies.
Main Results:
