A 33-year-old member asked:

Why isn't there an immune response to gangrene if it causes bacterial infections in fingers?

Frostbite: Frostbite is dead tissue from freezing damage. Gangrene would be from the dead tissue, not bacteria. Dead tissue may become secondarily infected with bacteria. Immune response does not help dead tissue & our bodies do not replace or regrow dead structures.

Interesting q: Gangrenous areas typically have no blood supply, the conduit for an immune response.
