by Chief Editor
written by Chief Editor

The Surprising Role of Lymphatic Vessels in Cancer Immunity

In the ongoing battle against cancer, the tumor microenvironment plays a pivotal role, influencing both the progression and the suppression of the disease. A groundbreaking study by researchers at the University of Geneva (UNIGE) has shed light on an unexpected player in this arena: the enzyme CH25H, found in the lymphatic vessels’ endothelial cells.

Overcoming Metastasis with Immune Support

Lymphangiogenesis, the formation of new lymphatic vessels, has long been associated with a poor prognosis in cancer patients due to its link with metastasis. However, this recent discovery offers a silver lining. The enzyme CH25H, identified within these lymphatic vessels, plays an instrumental role in bolstering the immune system’s response, particularly when enhanced by anti-tumor treatments.

According to Stéphanie Hugues, a full professor at the UNIGE, the lymphatic vessels’ role is multifaceted. While they do facilitate the spread of cancer, they are also crucial for mobilizing immune cells to attack tumors. This duality points to a more complex relationship between cancer and the immune system than previously understood.

Enzyme CH25H: A Key to Improved Prognosis

The study found that CH25H is overexpressed in the lymphatic endothelial cells of melanoma tumors. This enzyme converts cholesterol into 25-hydroxycholesterol, a compound known for its antiviral properties. Intriguingly, in the context of melanoma, 25-hydroxycholesterol undermines the tumor’s defenses by counteracting factors that typically inhibit immune cell activation.

Patients with high levels of CH25H in their tumors have been observed to have a better prognosis, particularly when treated with immune checkpoint inhibitors, a class of drugs that boosts the immune system’s ability to fight cancer.

Implications for Immunotherapy

The findings from the UNIGE team suggest that CH25H could serve as a biomarker for predicting the effectiveness of immunotherapy. This would allow for more personalized treatment plans, adjusting therapies based on the patient’s specific tumor characteristics.

Our discovery could therefore provide a biomarker for predicting the success of immunotherapy, enabling treatments to be adjusted according to the specific characteristics of each patient.

– Stéphanie Hugues, UNIGE Faculty of Medicine

Rethinking Lymphangiogenesis

The traditional view of lymphatic vessels as mere conduits for fluid and immune cells is being challenged. The research highlights the need to consider targeting specific functions within the lymphatic system rather than lymphangiogenesis as a whole. This nuanced approach could lead to more effective cancer treatments.

FAQ: Understanding the Study
