Scientists Discover ‘Cathartocytosis’: A Cellular Purge That Could Unlock New Cancer Treatments
ST. LOUIS, MO – In a stunning breakthrough that could reshape our understanding of healing and disease, researchers at Washington University School of Medicine and Baylor College of Medicine have identified a previously unknown cellular process they’ve playfully dubbed “cathartocytosis” – essentially, a way for cells to rapidly ‘vomit’ out their internal machinery to quickly adapt and repair damage. This discovery, published in Cell Reports, isn’t just about how bodies heal; it’s potentially a game-changer for early cancer detection and treatment strategies.
The ‘Cellular Vomit’ Explained: A Shortcut to Healing
For years, scientists have understood that injured cells respond with complex healing mechanisms. These include self-destruction of damaged components and, more recently, the ability of older cells to revert to a younger, more functional state. But this new research reveals a far more immediate response. Jeffrey W. Brown, MD, PhD, the study’s first author, explains that cathartocytosis is a rapid way for cells to discard their complex internal structures, effectively becoming “small, primitive cells” capable of quickly multiplying and repairing injury.
“Think of it like vomiting,” Dr. Brown told reporters. “It’s a disorderly but incredibly fast way to get rid of waste, allowing cells to focus on regrowth.” The research team initially observed this phenomenon while studying stomach damage in mice, but they believe it’s likely present in other tissues throughout the body.
Paligenosis and the Roots of Cathartocytosis
Cathartocytosis was discovered within the context of ‘paligenosis,’ a regenerative process first described in 2018 by Jason C. Mills, MD, PhD, a lead investigator on the current study. Paligenosis involves wounded cells reverting to a stem-cell-like state, enabling rapid division and tissue repair. Researchers initially believed cellular decluttering happened slowly within lysosomes, the cell’s waste disposal units. However, they consistently observed debris *outside* the cells, leading them to realize something more dramatic was happening.
The team’s experiments with mouse stomach lesions demonstrated that this “vomiting” response wasn’t a random occurrence, but a coordinated, standard reaction to injury. It’s a fundamental shift in how we understand cellular repair, suggesting that cells aren’t always relying on slow, controlled degradation – sometimes, they opt for a quick, albeit messy, purge.
The Dark Side of Cellular Purge: Inflammation and Cancer Risk
While cathartocytosis offers a powerful shortcut to healing, it’s not without its drawbacks. The rapid and disorderly nature of the process can trigger inflammation, potentially exacerbating chronic injuries and even increasing the risk of cancer. The ejected cellular waste can create a breeding ground for harmful mutations, particularly when older, already-mutated cells revert to a stem-cell-like state.
“In these gastric cells, paligenosis is a risky process, especially now that we’ve identified the potentially inflammatory reduction in cathartocytosis,” explains Dr. Mills. “If many older, mutated cells return to stem-cell states to repair an injury, and that injury also fuels inflammation, there’s an increased risk of acquiring and perpetuating harmful mutations.”
A New Tool for Cancer Detection?
Despite the risks, researchers are optimistic that understanding cathartocytosis could lead to innovative cancer detection and treatment strategies. Koushik K. DAS, MD, a WashU Medicine associate professor, has developed an antibody that binds to the cellular waste ejected during cathartocytosis. This could allow doctors to detect when the process is occurring, potentially identifying precancerous states at an early stage.
The team also suspects cathartocytosis plays a role in chronic conditions like Helicobacter pylori infections, which are known to increase the risk of stomach cancer. By learning to control this process – perhaps encouraging healing responses while blocking harmful cathartocytosis in chronic injuries – scientists hope to develop more effective therapies.
This discovery isn’t just a win for gastroenterology; it’s a fundamental leap forward in our understanding of cellular biology and the complex interplay between healing, inflammation, and cancer. As research continues, cathartocytosis promises to unlock new avenues for preventing and treating a wide range of diseases, offering a glimmer of hope for a healthier future.
