The primary function of the NIEHS (NIH) in research is to provide funds for a great variety of programs at many institutions.
Lupus, osteoarthritis, stem cell, gene, statin effect on musculoskeletal system, and many other research programs have received support.

One section, NIAMS, supports Arthritis, Musculoskeletal and Skin diseases. http://www.niams.nih.gov/News_and_Events/Spotlight_on_Research/2009/default.asp

If the republicans get in, look for severe cutbacks in available funds.
