Common inflammatory cause of laminitis

Explanation:
Endotoxin-driven systemic inflammation is the typical inflammatory trigger for laminitis. Endotoxin from Gram-negative bacteria in GI disturbances enters the bloodstream and activates immune cells to release cytokines (such as IL-1, IL-6, and TNF-alpha). This cascade increases vascular permeability and promotes inflammation in the hoof laminae, weakening the laminar attachments and allowing the pedal bone to rotate or sink. Relaxin isn’t involved in triggering laminitis; it’s a reproductive hormone. Ruminal acidosis can contribute to endotoxemia, but the inflammatory cause itself is endotoxin. Vasoconstriction is not the primary inflammatory mechanism driving laminar damage.
