This study is being conducted for families with siblings or twins in which one sibling has developed a systemic autoimmune disease and the other sibling does not have an autoimmune disease. The goal is to understand the genetic and environmental factors that may result in autoimmune diseases

Studies requiring gene expression analysis by microarray methods require the extraction of high quality RNA. Fresh, frozen tissue is the optimal sample for these studies. A detailed protocol to assist the investigator in tissue collection, RNA extraction and RNA quality assessment.

The NIEHS and NTP director shared updates on NIEHS scientific advances and answered questions about topics such as BPA and climate change.

Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation.

The Environmental Polymorphisms Registry (EPR) is a long-term research project to collect and store DNA from up to 20,000 North Carolinians in a biobank. By donating blood to the project, you will help scientists discover changes in our genes as a result of environmental exposures that may increase or decrease our risk for common diseases, such as diabetes, heart disease, and cancer.
