When your liver and pancreas get fatty, a protein called Fetuin-A wakes up immune cells in the pancreas, making them pump out a chemical that causes swelling and irritation—kind of like a false alarm that turns into a local riot.

The study found that a protein from a fatty liver (fetuin-A) triggers immune cells inside the pancreas to release a harmful inflammatory signal (IL-1β), and this only happens when a specific pathway (TLR4) is active — exactly what the claim says.
