Researchers have identified how a bacterial toxin linked to colorectal cancer breaches the colon’s protective barrier. The toxin binds to a receptor called claudin-4 to open that barrier.
Claudin proteins help seal junctions between intestinal cells. Binding to claudin-4 offers a mechanistic explanation for how the toxin may promote damage associated with colorectal cancer risk pathways.
The finding centers on receptor-level interaction rather than a new clinical treatment. The health-science brief names claudin-4 as the binding target without listing the bacterial species beyond the toxin context in the headline.
