Our interdisciplinary team studies how the immune system develops and functions through the lens of RNA biology. We are interested in learning how gene expression programs are regulated post-transcriptionally with the goal of manipulating cell fate. As one application of our basic research on regulation of hematopoiesis during ontogeny, our group discovered how hematopoietic stem cells (HSCs) from an adult donor can be reprogrammed to behave like their fetal counterparts. This method provides an alternative source of HSCs from human fetal liver which one day could be used for in utero transplantation to cure inborn errors of immunity or hematopoiesis including but not limited to sickle cell disease, beta-thalassemia and many primary immunodeficiencies.

Nicholas T. Cutrona, M.S.
Biologist
Education:
M.S., Georgetown University
Nicholas received his M.S. in Biochemistry and Molecular Biology from Georgetown University before joining NIAID in the Integrative Immunology section as a biologist in 2020. He has optimized RNA and DNA sequencing on short- and long-read platforms. Nicholas is interested in gene regulation during B cell development as well as regulation of MHC I expression.

Xiuhuai Liu, Ph.D.
Biologist
Education:
Ph.D., Scuola Normale Superiore, Pisa, Italy
Dr. Liu trained at NINDS as a postdoc and worked at NIMH as a research contractor, then joined NIAID as a biologist in 2011, and was the lab manager until 2014. He studies the roles of several genes on production and differentiation of fetal liver hematopoietic stem and progenitor cells (HSPCs) using knock-out, knock-in and transgenic mice.
