Methods and antisera for isolating and identifying subsets of CD8 T cells

A method for identifying the presence or absence of a subset of CD8 T cells that produce interleukin-13 upon activation (CD8IL-13 T cells), the method comprising:

• obtaining or having obtained a sample from a subject comprising a mammal, the sample comprising a population of CD8 T cells;
• quantifying a level of expression of at least a C10orf128 biomarker in the population of CD8 T cells
• comparing the level of expression of the C10orf128 biomarker in the sample to an expression level of such biomarker in a healthy control, wherein if the C10orf128 biomarker in the sample is upregulated relative to the expression level of the relevant healthy control, such upregulation indicative of the subset of CD8IL-13 T cells being present within the population of CD8 T cells;
• and
• administering or having administered an anti-C10orf128 antibody to the subject.
