This newly characterized population, which is likely overlooked due to the lack of NCR1, introduces a fourth subset to the Group 1 ILC spectrum, expanding its diversity to include two homeostatic (AsGM1- ILC1s and AsGM1+ NK cells) subsets and two infection-driven ILC1-like states (AsGM1intNCR1+ and AsGM1intNCR1-), all distinctly captured by the AsGM1 expression gradient. Here, NCR1 is linked to infection.
