These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion.

In this report, we describe 12 subpopulations of porcine gammadelta thymocytes based on their expression of CD1, CD2, CD4, CD8- isoforms and CD45RC. Our data suggest that gammadelta thymocytes can be divided into two major families: (a) one large family of CD4-gammadelta thymocytes that could be further subdivided according to the CD2/CD8alphaalpha phenotype and (b) a small family of CD4+ gammadelta thymocytes bearing CD8alphabeta and possessing certain unusual features in comparison with other gammadelta thymocytes. Maturation of gammadelta thymocytes within the CD4- family begins with proliferation of the CD2+ CD8- CD1+ CD45RC- gammadelta common precursor. This developmental stage is followed by diversification into the CD2+ CD8alphaalpha+, CD2+ CD8- and CD2- CD8- subsets. Their further maturation is accompanied by a loss of expression of CD1 and by increased expression of CD45RC. Therefore, individual subsets develop from CD1+ CD45RC- through CD1- CD45RC- into CD1- CD45RC+ cells. On the other hand, gammadelta thymocytes within the CD4+ family bear exclusively CD8alphabeta, always express CD1, but may coexpress CD45RC. These cells have no counterpart in the periphery. Our observations suggest that all peripheral CD8+ gammadelta T cells express CD8alphaalpha and that two subsets of these cells differing in major histocompatibility complex II expression, occur. We propose that one subset acquires CD8alphaalpha in the thymus while the second acquires CD8alphaalpha as a result of stimulation in the periphery.
