Learn About Silicosis American Lung Association

Mar 23, 2020 When people breathe silica dust, they inhale tiny particles of the mineral silica. Over time, the silica dust particles can cause lung inflammation that leads to the formation of lung nodules and scarring in the lungs called pulmonary fibrosis. This is a progressive disease that normally takes 10–30 years after first exposure to develop.

Experiencing an Adverse Immune Response Danger Dust

Nov 27, 2016 Autoimmune disease is not an exaggerated response to foreign matter. This syndrome occurs when foreign chemicals modify tissues or immune cells, affecting the regulation of immune response such as the production of antibodies and inflammatory response. The result is an immune response against our own tissues, tissue damage and disease.

Allergies and the Immune System Johns Hopkins Medicine

Allergic reactions begin in your immune system. When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may over react by producing antibodies that "attack" the allergen.

Allergies Immune Deficiency Foundation

Allergic diseases and symptoms occur because of an active immune system that reacts to things that are usually harmless, such as pollens, pet dander or foods. For that reason, it can be puzzling that people with immune deficiencies would have allergies. In fact, taken as a whole, people with immune deficiencies probably have a far greater disease burden of allergy than the
