A survey of silicosis patients and people exposed to silica dust was set up in an effort to look for any relationship between humoral and cell-mediated autoimmune phenomena. It was found that in both sets of subjects, the level of Fc IgG receptor-bearing T lymphocytes was significantly reduced, there was also an inverse correlation between these cell concentrations and IgG- and IgM-circulating immune complex levels. In addition, raised levels of various autoantibodies were found in both groups, however, none of the exposed subjects has developed silicosis to date.
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
