Ang Cui discusses her career and work on the Immune Dictionary, a compendium of single-cell transcriptomic profiles of immune cell types in response to cytokines in mouse lymph nodes. The podcast covers topics such as the process of submitting and reviewing scientific papers, creating figures for the paper, mapping cell responses to cytokines, comparing mouse and human immune systems, and future research plans.
The Immune Dictionary provides a comprehensive map of how different immune cells respond to specific cytokines, giving insights into immune cell behavior that was previously unknown.
The immune dictionary offers a valuable resource for researchers to explore immune cell behavior, investigate combinatorial effects of cytokines, and inform therapeutic strategies.
The traditional belief that only macrophages polarize is inaccurate, as every cell type responds to cytokines in different ways, highlighting the complexity and plasticity of cytokine responses in human cells.

Development of the Immune Dictionary
The podcast episode discusses the development of an immune dictionary that maps the responses of different immune cells to 86 cytokines at a single-cell resolution. The dictionary was created through an ambitious project involving the injection of individual cytokines into mice, followed by single-cell sequencing of lymph nodes to analyze the gene expression changes. The aim was to understand how different cell types respond to specific cytokines, providing valuable insights into immune cell behavior that had not been characterized before.
Insights from Figure 1D: Cell-Type-Specific Cytokine Responses
Figure 1D of the paper presents the cell-type-specific responses to cytokines. It highlights the diverse set of immune cell types that respond to different cytokines and provides a comparative analysis of the magnitude of these responses. The findings reveal cell types that were not previously associated with cytokine responses, generating new hypotheses for their functions and potential involvement in specific diseases. The comprehensive mapping of cell-type-cytokine interactions in this figure provides a valuable resource for researchers to explore immune cell behavior and its implications in various contexts.
The Potential of the Immune Dictionary for Research and Therapy
The episode discusses the potential uses of the immune dictionary for generating hypotheses and guiding research in immunology. By providing a comprehensive map of cytokine responses in different immune cell types, the dictionary offers insights into the complexities of the immune system and the interactions between cytokines and cells. Researchers can leverage this resource to explore the effects of specific cytokines, investigate combinatorial effects of multiple cytokines, and study the impact of cytokine therapies. The immune dictionary serves as a valuable tool for understanding immune responses and has the potential to advance research in immunology and inform therapeutic strategies.
Diverse Cytokine Responses in Different Cell Types
The podcast episode discusses the diverse cytokine responses in various cell types. The speaker explains that the traditional belief that only macrophages polarize is not accurate, as every cell type responds to cytokines in different ways. The example of NK cells is provided, where four different polarization states were identified, each responding to specific cytokines. The findings highlight the complexity and plasticity of cytokine responses in human cells.
Delivering Cytokines to Lymph Nodes and Analyzing Data
The episode delves into the technical aspects of delivering cytokines to lymph nodes and collecting RNA-seq data. The speaker describes the process of preparing and injecting cytokines into mice, collecting lymph node cells, and conducting data analysis. The importance of timing, reproducibility, and the need for replicates is emphasized. The speaker also mentions the development of a companion software called Immune Response Enrichment Analysis (IREA) to aid researchers in understanding immune responses in their own data.
Ang Cui joins Immune to discuss her career and her work on establishing the Immune Dictionary, a compendium of single-cell transcriptomic profiles of more than 17 immune cell types in response to each of 86 cytokines (>1,400 cytokine-cell type combinations) in mouse lymph nodes in vivo.
