Major genetic breakthrough for ankylosing spondylitis brings treatment hope

Researchers have identified two genes, ARTS1 and IL23R, that increase the risk of developing ankylosing spondylitis, a common disease causing back pain and progressive stiffness. A potential treatment for Crohn's disease may also be applied to this disease, providing a major step towards being able to treat ankylosing spondylitis.

MIT gel changes color on demand

The team developed a structured gel with tunable optical properties that can rapidly change color in fractions of a second. The gel's color shift is limited to one dimension due to its one-dimensional periodic stack structure, resulting in a dramatic improvement over earlier color-changing gels.

UT rheumatologists discover 2 genes related to disabling form of arthritis

Researchers at the University of Texas Health Science Center at Houston have identified two genes, ARTS1 and IL23R, that contribute to the development of ankylosing spondylitis, a chronic and disabling form of arthritis. This discovery is expected to lead to new therapies and potentially allow for early identification of patients at risk.

Study reveals 2 genes linked to disabling arthritis

An international team of researchers has discovered two genes linked to ankylosing spondylitis, a painful and progressive disease affecting the spine. The study also validated the association of two genes implicated in Graves' disease, increasing the number of known genes involved in both diseases.
