摘要
The present invention relates to a method, in particular an in vitro method, for identifying follicular helper T cells, comprising analyzing the methylation status of at least one CpG position in the mammalian gene region for leukemia inhibitory factor (LIF), wherein a demethylation of said gene region is indicative for a follicular helper T cell, when compared to a non-follicular helper T cell. The analyses according to the invention can identify follicular helper T cells on an epigenetic level and distinguish them from all other cells in complex samples, such as, for example, other blood cells. The present invention furthermore provides an improved method for quantifying follicular helper T cells in complex samples. The method can be performed without a step of purifying and/or enriching cells, preferably in whole blood and/or non-trypsinized tissue.
