Investigation of the function of the ER/mitochondria contact sites in cell physiology and disease

Every cell in the body relies on close physical contact between two of its internal compartments—the mitochondria and the endoplasmic reticulum—to stay alive, yet scientists do not fully understand how these contact points work or what happens when they break. These contact sites act as signalling hubs, allowing the two compartments to exchange calcium, lipids, and other molecules essential for energy production, cell movement, and programmed cell death. When these contacts malfunction, cells lose their ability to regulate these processes, a defect that has been linked to human diseases. The researchers aim to map the architecture of these contact points and determine their specific roles in normal cell physiology, using biochemical and molecular tools. This is fundamental science. There is no immediate clinical application. However, understanding how these contact sites govern cell survival and metabolism could eventually illuminate the root causes of conditions such as diabetes, neurodegeneration, and metabolic disorders—diseases where cellular signalling goes awry. Past discoveries about organelle communication have already reshaped how researchers think about disease mechanisms; this work adds a critical piece to that picture.
