Additionally, supravital cell staining with Hoechst 33342, which is primarily used for sorting live cells based on DNA-content differences for their subsequent culturing, is described. Also presented are methods for staining cell nuclei isolated from paraffin-embedded tissues. Available algorithms are listed for deconvolution of DNA-content-frequency histograms to estimate percentage of cells in major phases of the cell cycle and frequency of apoptotic cells with fractional DNA content. © 2017 by John Wiley &amp; Sons, Inc.</p>","PeriodicalId":10733,"journal":{"name":"Current Protocols in Immunology","volume":"119 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/cpim.36","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35511927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using flow cytometry, these cells can be analyzed by labeling with fluorophore-conjugated antibodies. The recent expansion of fluorescence flow cytometry technology, in conjunction with the ever-expanding understanding of the complexity of the immune system, has led to the generation of larger high-dimensional fluorescence flow cytometry panels. However, as panel size and complexity increases, so too does the difficulty involved in constructing high-quality panels, in addition to the challenges of analyzing such high-dimensional datasets. As such, this unit seeks to review the key principles involved in building high-dimensional panels, as well as to guide users through the process of building and analyzing quality panels. Here, cytometer configuration, fluorophore brightness, spreading error, antigen density, choosing the best conjugates, titration, optimization, and data analysis will all be addressed. © 2017 by John Wiley &amp; Sons, Inc.</p>","PeriodicalId":10733,"journal":{"name":"Current Protocols in Immunology","volume":"119 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/cpim.37","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35511960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although blood monocytes are the source of intestinal macrophages in the developed mucosal immune system, blood monocytes and intestinal macrophages from healthy human subjects display distinct phenotypic and functional differences. Blood monocytes can be induced to polarize into M1 and M2 macrophages, whereas intestinal macrophages appear to be terminally differentiated and are unable to undergo such inducible polarization. Nevertheless, in response to local conditions, monocytes differentiated into intestinal macrophages display phenotypic and functional characteristics that enhance their capacity to provide non-inflammatory host defense and participate in local immunoregulation.

Type 1 regulatory T cells (Tr1 cells) are an important subset of CD4+ T cells that prevent excessive inflammatory responses and maintain immune tolerance. The anti-inflammatory role of Tr1 cells is mediated in part by their production of interleukin 10 (IL-10), which dampens the function of both antigen-presenting cells and antigen-specific effector T cells. Additionally, Tr1 cells can kill effector and myeloid cells through the perforin-granzyme B pathway. Adoptive transfer of in vitro differentiated Tr1 cells can be used to suppress autoimmune tissue inflammation in vivo.

Eosinophil levels in the blood are relatively low. However, under steady-state conditions and in settings of allergic inflammation, parasite infections, or even cancer, they migrate and mainly reside in mucosal tissues where they have key effector and immune-modulating functions. Functional studies using eosinophils are not simple, since these cells are terminally differentiated and rapidly die in vitro. Thus, establishing simple methods to characterize, obtain, and functionally assess eosinophil activities is important.
