Topic: Vesicles

The discussion focuses on how viruses act as intracellular parasites that hijack the body's vesicular trafficking machinery for replication and transmission. The guest argues that exosomes can be manipulated to carry viral information, a process he calls exosome mimicry, which complicates the distinction between host cells and pathogens.

Brown addresses the popular "exosome theory," which suggests viruses are merely cellular excretions used for detoxification. He argues against this view, stating that viral protein capsules and genomes are clearly foreign to the human body and distinct from the lipid vesicles involved in standard cellular processes like neurotransmission.
