Jagged2 loss in niche drives HSC changes

In this week's episode, Blood editor Dr. Laurie Sehn interviews authors Drs. Anastasios Karadimitris and Maria Carolina Florian on their papers published in Volume 147 Issue 2 of Blood. Dr. Karadimitris' paper "Off-the-shelf dual CAR-iNKT cell immunotherapy eradicates medullary and leptomeningeal high-risk KMT2A-rearranged leukemia", discusses the success of bispecific CAR-iNKT cells targeting CD19 and CD133 in pre-clinical models, prompting the clinical development of this class of product. Dr. Florian's paper, "A Notch trans-activation to cis-inhibition switch underlies hematopoietic stem cell aging" proposes that the Jagged2/Notch interaction is a key regulator of hematopoietic stem cell divisional symmetry during aging and offers insights that may inform strategies to restore regenerative function in aged hematopoiesis.
