N a correspondence in between the CD27-CD11b+ and also the CD27+CD11b- mouse NK cell subsets and also the CD56dim and CD56bright human NK cell subsets, respectively [1388]. Moreover, this study revealed spleen- and blood- distinct NK cell signatures typical in each species, highlighting the significance in the organ of origin in the definition of a cell population. Even though in blood and spleen NK cells represent essentially the most abundant ILC subset, in tissues, you will find higher proportions with the other ILCs subsets, which are largely tissue-resident. CD127 is classically employed to identify ILCs and distinguish them from NK cells, since it isn’t expressed by NK cells of liver, intestine, skin, uterus, IL-17C Proteins MedChemExpress salivary gland, bone marrow, or lymph nodes. On the other hand, CD127 is expressed by NK cells in the thymus and in some spleen populations, and it really is not expressed by liver and intraepithelial gut ILC1s. As a result, the phenotypic characterization of tissue-resident NK cells is much more complicated and requires the evaluation of extra markers. In specific, NK cells share numerous characteristics with ILC1s, they each make IFN- as the most important cytokine and call for Tbet for this function. Having said that, while NK cells require Eomes for their development course of action, ILC1s create in the absence of this transcription aspect. Moreover, ILC1s are commonly noncytotoxic and express lower levels of perforin in comparison to NK cells [1342]. Regardless these developmental and functional variations, ILC1s have some phenotypic markers in common with NK cells (see Chapter VI Section 4 Innate lymphoid cells), like NK1.1 in mice and NKp46 in both humans andAuthor Manuscript Author Manuscript Author Manuscript Author ManuscriptEur J Share this post on:
