Task: Intent Identification
Input (English): Wiskott-Aldrich syndrome (WAS) is a severe disorder characterized by thrombocytopenia, eczema, immunodeficiency, and increased risk of autoimmune disease and lymphoid malignancies. The immunodeficiency caused by a lack of WAS protein expression has been mainly attributed to defective T-cell functions. Whether WAS mutations differentially influence the T-cell receptor (TCR) diversity of different T-cell subsets is unknown.', 'We aimed to identify the degree and pattern of skewing in the variable region of the TCR β-chain (Vβ) in different T-cell subsets from patients with WAS.', 'The TCR repertoire diversity in total peripheral T\xa0cells, sorted CD4(+) and CD8(+) T cells, and CD45RA(+) (CD45RA(+)CD45RO(-) cells) and CD45RO(+) (CD45RA(-)CD45RO(+) cells) CD4(+) and CD8(+) T cells from patients with WAS and age-matched healthy control subjects was analyzed and compared by using spectratyping of complementarity-determining region 3. The complementarity-determining region 3 of TCRβ transcripts in CD45RA(+)CD4(+) and CD45RA(+)CD8(+) T cells, CD45RO(+)CD4(+) T cells, CD8(+) terminally differentiated effector memory T (Temra) cells, and naive CD8(+) T cells (CD8(+)CD45RO(-)CCR7(+) cells) from patients and control subjects were analyzed and compared by using high-throughput sequencing.', 'The TCR repertoire diversity in CD45RO(+)CD4(+) T cells and CD8(+) Temra cells of patients with WAS was significantly skewed in comparison with that seen in age-matched control subjects.
