Understanding Autophalogy: The Cellular Housekeeper

Autofony, from the Greek for quentiquents; self-eating, quenquentes; is a tightly regulated process that degrades andd recycles damaged organelles, misfolded proteins, and text cellular contexts. It is essential for maintaing cellulair homeostasis, especially under stres conditions such as dietient depention, oksydative stress, and infection. There are three main type of authaugy in amotialiaid cells:
