Anguera Laboratory
Our laboratory investigates X-chromosome Inactivation and how this epigenetic process contributes to female-biased autoimmunity.
Our Research
At the Anguera Laboratory, we are investigating how female lymphocytes maintain X-chromosome Inactivation, which is an epigenetic process responsible for equalizing gene expression between sexes. X-chromosome Inactivation silences one X-chromosome in female cells, and this process is initiated and maintained by the long noncoding RNA Xist.
Lab Mission
- To investigate the epigenetic regulatory mechanisms of the inactive X chromosome in immune cells that maintain transcriptional silencing of most genes while promoting X-linked gene expression of specific genes
- To determine the genetic and epigenetic contributions responsible for the female bias in autoimmune diseases such as lupus and scleroderma
- To investigate how X-linked gene expression contributes towards sex biased disease outcomes following pathogen infections
Interviews With Dr. Anguera
NPR (February 2024): “Four out of five autoimmune diseases patients are women, and scientists want to know why“
Radiolab (August 2021): “The Unsilencing” A new study published in the magazine Cell looks at why women are more prone to getting autoimmune diseases like lupus, multiple sclerosis and rheumatoid arthritis.
