Title: How does asbestos get into the pleural lining?
Post by: DoctorBeaver on 04/02/2009 00:14:21
Mesothelioma is caused by asbestos fibres in the pleural lining. But how does it get there? Asbestos can be breathed into the lungs, but how does it pass through the lungs into the lining?

I'd go with diffusion, micro punctures, and pure dumb luck.

Tiny asbestos crystals are "engulfed" by scavenger white cells (defense: 'macrophages') but cannot be digested enzymatically because of their size and shape. Macrophages die exausted, so other soldiers come to help, creating a persistent (chronic) state of reaction-inflammation, locally, for years and years...
