I heard that many immune cells contribute to remove/eliminate undesired cells in the body such as senescenced cells, cancer cells, virus infected cells, or allogenic transplanted cells by phagocytosis. In this case, up to which levels do they degrade the components of those cells (such as proteins, nucleic acids, lipids, etc) in their cells? And what is going to do with those "wasete materials" in the body? Do they have specific mechanisms and targets to deliver those degraded components in the body? Or just runnning through the body by blood stream?
I am wondering which cell types are truly responsible for "the final degradation of those eliminated cell-components", and "how the immune cells (the cells eating those cells) deliver waste materials to the target cells".
Thank you for your attention
