Effects of carbon nanotubes on intercellular communication and involvement of IL-1 genes.

ABSTRACT: An increasing amount of products containing engineered nanoparticles is emerging. Among these particles are carbon nanotubes (CNTs) which are of interest for a wide range of industrial and biomedical applications. There have been raised concerns over the effects of CNTs on human health. Some types of CNTs are classified as group 2B carcinogens by the International Agency for Research on Cancer. CNTs may also induce pulmonary inflammatory and fibrotic effects. By utilizing CNTs of different lengths, we investigated the role of the proinflammatory cytokine, interleukin-1 (IL-1) on gap junctional intercellular communication (GJIC) by using IL-1 wild-type (IL1-WT) and IL-1 knock-out (IL1-KO) cells. GJIC decreased equally in both cell types after CNT exposure. Immunofluorescence staining showed
