Defining epigenetic mechanisms that regulate X-chromosome inactivation in the immune system and contribute to sex bias in infectious and autoimmune disease.

Our laboratory investigates X-chromosome Inactivation, and how this epigenetic process contributes to female-bias with autoimmunity & immune responses.

We are investigating how female lymphocytes maintain X-chromosome Inactivation (XCI), 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.
