The present invention relates to a method, in particular an in vitro method, for identifying CD8 positive subpopulations of a mammal, wherein said method comprises analyzing the bisulfite convertibility of at least one CpG position in the CD8 beta and CD8 alpha cell specific bisulfite convertibility gene region according to SEQ ID No. 1 and 2, wherein a bisulfite convertibility of at least one CpG position in said gene regions is indicative for a CD3+CD8+ and/or CD3+/−CD8+ cell. The analyzes according to the invention can identify CD3+CD8+ and/or CD3+/−CD8+ cells on an epigenetic level and distinguish them from all other cells in complex samples, such as, for example, other blood cells.

Epigenetic modification of the loci for CAMTA1 and/or FOXP3 as a marker for cancer treatment
The present invention relates to a method, in particular an in vitro method, for pan-cancer diagnostics, comprising identifying the amount and/or proportion of stable regulatory T cells in a patient suspected of having cancer through analyzing the methylation status of at least one CpG position in the gene foxp3 and/or the gene camta1 or orthologous or paralogous genes thereof, wherein an increased amount and/or proportion of stable regulatory T cells in said patient is indicative for an unspecific cancerous disease. In a second aspect thereof, the present invention relates to a method for diagnosing the survival of a cancer patient, comprising identifying the amount and/or proportion of stable regulatory T cells in said cancer patient through analyzing the methylation status of at least one CpG position in the gene foxp3 and/or the gene camta1 or orthologous or paralogous genes thereof, wherein a demethylation in the gene foxp3 and/or the gene camta1 or orthologous or paralogous genes thereof, is indicative of a stable regulatory T cell, and wherein an increased amount and/or proportion of stable regulatory T cells in said cancer patient is indicative for a shorter survival for said cancer patient. Furthermore, the present invention relates to an improved treatment of cancers based on the inventive methods, and a kit for performing the above methods as well as respective uses.
