The changing immune landscape of innate-like T cells and other innate cells throughout life.

ABSTRACT: Spectral flow cytometry is an advanced immunological tool that can enable comprehensive analysis of the immune system by simultaneously comparing innate and adaptive immune cells. Here, using a 40-color antibody panel, we advance our knowledge of innate-like cells by investigating chemokine receptors and maturation markers not usually assessed on these populations, examining age-related effects on these immune cell subsets. We characterize phenotypic changes of peripheral blood mononuclear cells (PBMCs) in three age groups: newborns (cord blood), adults aged 20-30 years, and adults aged > 70 years. We compare the age-related changes of innate cells, including ILCs, NK cells, monocytes, dendritic cells, and innate-like T cells, comparing them with memory T cells. We also examine subsets of
