Mtor Signalling

mTOR signalling

mTOR signalling describes a set of chemical reactions inside cells that are organized around a protein called mTOR. This protein acts like a central control switch that tells the cell when to grow, make new proteins, and store or use energy. It listens to many signals — such as nutrients, growth factors, and the cell’s energy level — and then adjusts how the cell behaves. One important action of this pathway is to promote protein synthesis and block cellular recycling processes when resources are plentiful. When nutrients are scarce or energy is low, the pathway eases back and allows the cell to conserve resources and recycle damaged parts. This control system matters because it helps cells adapt to changing conditions and maintain healthy function. If mTOR signalling is too active or not active enough, it can contribute to problems such as cancer, metabolic disease, or age-related decline. Scientists study mTOR signalling to understand these diseases and to develop medicines that can dial the pathway up or down. Lifestyle factors like diet, exercise, and sleep also influence it, so understanding this system helps explain how daily choices affect long-term health.
