Galectins are proteins that interact with carbohydrates and play an important role in cellular processes. They participate in the binding of cells to the intercellular substance and also regulate the rate of cell division. In cancer, galectins promote tumor growth into surrounding tissues and metastasis.
The study found that galectins 1 and 3 have significant effects on immune system function and tumor progression, especially in advanced stages of cancer. This discovery could lead to the development of new genetically modified biologic drugs and increase the effectiveness of treatment.
