Imaging Mass Cytometry used to investigate tumor and blood microenvironments and tertiary lymphoid structure.

Hear Dr. Akil Merchant, MD, describe how research teams from the University of Southern California use Imaging Mass Cytometry™ to assess circulating tumor cells in the blood and analyze immune cells within the tumor microenvironment.

In this recorded live seminar, Merchant discusses:

• how Imaging Mass Cytometry was integrated with the HD-SCA assay to study the role of CTCs in prostate and breast cancer
• the simultaneous analysis of multiple markers to identify T^REG cells within the tumor microenvironment
• the characterization of immune infiltrate in Hodgkin’s lymphoma

Researchers in Merchant’s lab are investigating how tumor cells interact with their microenvironment and how this interaction contributes to the development and maintenance of cancer. They are studying how immune cells are trafficked into the tumor space and how immune cells can be harnessed to treat cancer. They are also interested in signaling pathways in cancer cells that confer resistance to chemotherapy. Merchant is a practicing hematologist and oncologist at USC Norris Comprehensive Cancer Center. He also participates in several clinical trials for patients with various cancers.

Assessment of cell-to-cell interactions and the tissue ecosystem by Imaging Mass Cytometry supports the Bodenmiller lab’s goal of using precision medicine to revolutionize disease treatment.

Hear Bernd Bodenmiller, PhD, describe how this new approach provides researchers with an unprecedented view of complex cellular phenotypes and their relationships in the context of the tissue microenvironment.

In this recorded live seminar, Bodenmiller discusses:

• how Imaging Mass Cytometry™ empowers a multiplexed tissue view from molecules to morphology
• the development of histoCAT™ software and how it enables deep analysis of cell type and cellular social networks
• the use of Imaging Mass Cytometry to assess cellular heterogeneity and identify a variety of phenotypes in breast cancer samples
• an approach to profiling of tumor sphere cultures

Bodenmiller’s lab develops experimental and computational methods to unravel regulatory systems on the single-cell level that underlie cancer development. His group’s goal is to develop methods based on CyTOF® technology to quantitatively analyze trans-cellular circuits. Based on the mass cytometry data, they model and analyze how complex cell phenotypes in tumors are controlled, with the hope that this will enable targeted modulation that interferes with tumor development.

Stanford researchers describe how their integration of CyTOF® mass cytometry analysis with other omic approaches revealed the existence of an immune clock during human pregnancy.

In this recorded webinar, Dr. Brice Gaudilliere, MD, PhD, and Nima Aghaeepour, PhD, both of Stanford University School of Medicine, describe how they characterized the molecular pacemakers of pregnancy by integrating CyTOF® mass cytometry analysis and other omic approaches on blood samples collected throughout pregnancy.

The maintenance of pregnancy relies on a finely tuned immune balance between tolerance to the fetal allograft and protective mechanisms against invading pathogens. Demonstrating the chronology of immune adaptations to a term pregnancy provides the framework for future studies examining deviations implicated in pregnancy-related pathologies including preterm birth and preeclampsia.

Gaudilliere presents data demonstrating that these adaptations are precisely timed, reflecting an immune clock of pregnancy in women delivering at term. An elastic net model with prior Bayesian distributions extracted from literature-based knowledge of the immune was used to develop a predictive model of interrelated immune events that accurately captured the chronology of pregnancy.

Aghaeepour describes how the immunological dataset derived from the mass cytometry analysis was integrated with other omic datasets collected simultaneously at each time point, including data from the transcriptome, microbiome, proteome and metabolome. He also presents a novel computational approach combining all available omic datasets into a predictive model that reveals unique interactions between the different pacemakers of pregnancy.

Researchers identify a unique population of pathologic CD4+ T cells in both blood and synovial fluid using mass cytometry

In this video, Dr. Deepak Rao, MD, PhD, of Brigham and Women’s Hospital presents his recent research using mass cytometry and multidimensional flow cytometry to identify key pathologic T cell populations in the synovial fluid of subjects with rheumatoid arthritis.

Determining the pathologic functions of T cells that infiltrate target tissues remains a central challenge in autoimmune diseases. In this video, Dr. Deepak Rao, MD, PhD, of Brigham and Women’s Hospital describes recent work, published in Nature, identifying a unique population of pathologic CD4⁺ T cells, called T peripheral helper (T_PH) cells, that is markedly expanded in the joints of subjects with rheumatoid arthritis (RA). Rao and colleagues used mass cytometry and multidimensional flow cytometry to interrogate T cell populations in synovial tissue and blood from research subjects with RA, a chronic immune-mediated arthritis that affects up to 1% of the population.

Mass cytometric analysis of RA synovial tissue cells revealed a strikingly expanded population of PD-1^hiCXCR5^-CD4⁺ T cells, which constituted ~25% of synovial CD4⁺ T cells. Surprisingly, these cells are not exhausted, but instead highly express factors enabling B cell help, including IL-21, CXCL13, ICOS, SAP and MAF. Like T follicular helper (T_FH) cells, PD-1^hiCXCR5^- cells from synovium and blood induce plasma cell differentiation in vitro via IL 21. However, RNA-seq transcriptomics robustly separates PD-1^hiCXCR5^- cells from T_FH cells, with altered expression of Bcl6 and Blimp-1 and unique expression of chemokine receptors that direct migration to inflamed sites, such as CCR2, CX3CR1 and CCR5, in PD-1^hiCXCR5^- cells.

Rao and colleagues propose that PD-1^hiCXCR5^- T cells represent a T_PH cell population, analogous to T_FH cells, that supports B cell responses in pathologically inflamed nonlymphoid tissues. Given their marked expansion in RA joints, these cells may be important in driving pathologic B cell responses and autoantibody production within the inflamed target tissue.

Michelle Poulin, PhD, of Fluidigm provides a brief overview of mass cytometry, the high-parameter, single-cell analysis technology used by Rao in his research.
