Researchers from Leiden University Medical Center have published a new study in the Journal of Allergy and Clinical Immunology that provides new insights into how the human thymus is populated with the cells that give rise to T cells.
In the study, "At least 3 different progenitors with BM counterparts seed the thymus," the researchers show that the human thymus is seeded by at least three distinct populations of progenitor cells that have counterparts in the bone marrow. These findings improve our understanding of the earliest stages of human T-cell development and the continuous renewal of the immune system.
Understanding which progenitor cells contribute to T-cell formation is important for developing improved stem cell and gene therapy strategies for inherited immune disorders. This work contributes to Cure4Life's mission to advance innovative therapies for rare genetic diseases.
