Comparison between biological effects of asbestos and CNTs

Cell/tissue response


Particle uptake

Demonstrated with both types. Conflicting results with CNTs. Exocytosis found with CNTs, so far not investigated with asbestos.


Both cytotoxic.

DNA damage, mutation, gene interaction

Found with both asbestos and CNTs.


Gene transfer is with asbestos. CNT gene knockdown.


Both types are cleared via the lymphatic system and found in different organs

Inflammation, granulomas, fibrosis

Found with both asbestos and CNTs. Both types show dependence of biological effects with fibre dimensions: bioactivity of long fibres.


MM found with both asbestos and CNTs by peritoneal exposure.
