摘要
Abstract Advancements in cell analysis capabilities have significantly expanded our understanding of the complexity of immunological systems. As the need for deeper analysis has increased, many laboratories have employed a set of lineage markers to define a cell population, followed by the addition of unique markers specific to their biological question. Utilizing regulatory T cells (Treg) as a model population, we describe the design of an 8-color backbone panel on a 12-Color BD FACSLyric™ flow cytometer that can be supplemented with 4 drop-in markers (colors) to characterize two critical facets of Treg biology: activation and homing. Intelligent panel design enabled identification of human naïve and activated Treg cells utilizing established Treg markers (CD3, CD4, CD25, CD127, FoxP3, CD45RA). CD15s and CD161 were included in the 8-color backbone panel to identify functionally suppressive effector and/or pro-inflammatory cytokine secreting Tregs. Importantly, addition of a 4-color drop-in activation panel (PI16, CD147, CD39 and HLA-DR) or a 4-color drop-in homing panel (CCR4, CCR6, CXCR3 and CD31) did not impact resolution of the backbone Treg population(s), while providing new and interesting insights into Treg biology. We highlight the utility of a modular panel design approach that provides an efficient, scalable, and standardized solution for complex analysis of essentially any cell population of interest.
