Abnormal T cell apoptosis

What it means

Abnormal apoptosis by peripheral blood T cells in an in vitro culture, compared to a healthy control sample. May be either spontaneous, induced by UV, X-ray, FasL or other agens. Commonly measured by surface expression of phosphatidyl serine labelled by Annexin V, but other methods such as staning of cleaved Caspases may be used by different laboratories.
