Research Question
"The abstract claims C. butyricum-GLP-1 crosses the BBB and binds to GLP-1 receptors, but this is mechanistically implausible for a bacterial organism. The mechanism by which a gut bacterium could traverse the BBB and the actual source of GLP-1 receptor binding remains unexplained.
