Lysosomes: Cleaning Up Dead Organelles & Viruses

AI Thread Summary
Lysosomes play a crucial role in cellular maintenance by breaking down waste materials, damaged organelles, and intruders like viruses. However, their effectiveness against viruses is limited primarily to those that enter cells through endocytosis, and they may only slow down infections rather than eliminate them. Research indicates that inhibiting lysosomal function can enhance HIV infection, suggesting that lysosomes are not suitable for direct antiviral production. Injecting lysosomes could lead to significant cellular damage due to their uncontrolled uptake of various substances and potential leakage of harmful factors outside the cell. While lysosomes are considered a target for therapeutic strategies, their role in antiviral production is not straightforward, leading to the conclusion that they are not an effective means of creating antivirals.

Lysosomes help to clean up dead organelles and intruders like viruses. So, can't they be used to produce anti virals?

Lysosomes are intracellular organelles containing an acidic environment and a variety of enzymes. They're considered the "recycling bins" of the cell in that they break down waste materials and damaged components. In terms of viruses as far as I'm aware they only break down viruses that have entered the cell via endocytosis, most haven't so at best they slow infection:

If you were to just inject lysosomes you'd probably cause a lot of damage. If they aren't regulated they could uptake all sorts of things you don't necessarily want to and outside the environment of the cell they aren't going to be maintained, they'd probably leak with time releasing damaging factors. They are a target for therapy but for different reasons

Thank you so much! It really helped. Best answer ever. But if the question is yes/no type, what would you say?

Is this homework?
 
No, this isn't. It's my own question. My teacher didn't answer when I asked her. And I didn't find satisfactory answer anywhere else. Neither on internet nor in books.

It's rare anything in biology can be shortened to yes/no and doing so is often unnecessarily restrictive. Having said that I would answer no, the processes by which viruses are broken down would not seem to be a good way to produce antivirals. A potential target may be uptake of viruses by the lysosome but that isn't the same thing.
