While memory T lymphocytes (with low CCR7 and CD62L expression) prevailed in both XLP patients, in patient 9, who developed acute infectious mononucleosis (AIM) and received B cell ablative treatment, the predominant phenotype was that of late effector CD8 T cells (CD27\u2013, CD28\u2013, CCR7\u2013, CD62L\u2013, CD45 RA+, perforin+), while in patient 4 (who did not suffer AIM) the prevalent phenotype of CD8 T lymphocytes was similar to that of normal controls (N) or to that of adult individuals who recovered from AIM: CD27+\u2003, CD28+, CCR7\u2013, CD62L\u2013, CD45\u2003RO+ and perforin\u2013. CD57 expression (related to senescence) was also higher in CD8 T cells from patient 9 than in patient 4, AIM or N. Persistently high EBV viral load was observed in patient 9. The results obtained from this limited number of XLP patients suggest that events related to the initial EBV encounter (antigen load, treatment, cytokine environment) may have more weight than lack of SH2D1A in determining the long-term differentiation pattern of CD8 memory T cells.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2006.03300.x","type":"journal-article","created":{"date-parts":[[2008,10,13]],"date-time":"2008-10-13T18:50:13Z","timestamp":1223923813000},"page":"456-464","source":"Crossref","is-referenced-by-count":6,"title":["Factors
