comment Why do we dream?
There're so many theories...personally, I think dreaming is the brain trying to defragment, going over the past memories and getting rid of the connections that are not deemed as important. And this process of memory consolidation is seen as a dream. This explains why we often dream about the things that has happened during the day.

comment How do you express and detect GLP-1 receptors?
Try polyclonal antibodies. It might just be that your antibody isn't picking up the epitope.

comment How are our senses dimmed during sleep?
That's a common theory, but the question is how? How are these 'receptors' weakened? What it is that controls both these receptors and sleep?

comment Autophagy in eukaryotic cells
Any papers by Daniel Klionsky and Beth Levine should definitely be used for reference, they are the two biggest names in the field today.

comment Autophagy in eukaryotic cells
To answer your question - you can distinguish the two processes as their place of origins, phagocytosis originates at the cell membrane and autophagy originates inside the cell. The phagocytotic process may feed into the autophagosomal process, although it may not be an requirement. If you read the review I suggested, you'll appreciate that some bacteria that is taken in using phagosomes, break out of their phagosomes and replicate in the cell. This is when autophagy can come in and restrict their replication. So I, a very crude distinction would be - phagocytosis outside, autophagy inside

Having said this, no one is sure as to the origins of the autophagosome membrane - where the lipids are sourced from.

comment Autophagy in eukaryotic cells
Like I said, autophagosomes can take up any cargo - this includes other vesicles and phagosomes. The autophagosome is double-membraned, so when it fuses with the lysosome, the inner membrane is 'released' into the lumen of the lysosome, whereas the outer membrane fuses with that of the lysosome. Thus, the outer membrane of the autophagosome would resemble more of the lysosomal membrane (and they do share similar markers and it's often hard to distinguish the two in microscopy). This is different from the the membrane of phagosomes, which originate from the plasma membrane.

comment Do non-human animals suffer from insomnia?
Commenting on the how, you can wire animals using EEG as you do with humans to see their brain activity. Provided you have a profile of the different patterns that correlates to different stages of sleep.
