Case 1. Robert Davies, a 50-year-old man, presents with tiredness and lethargy. Examination demonstrates pallor and jaundice. Investigations reveal anemia that is consistent with warm autoimmune hemolytic anemia (AIHA; Figure 1). He has no evidence of any other autoimmune disease or chronic lymphocytic leukemia (CLL) and is not taking any medications; these(More)
Natural killer (NK) cells are cytotoxic lymphocytes that lack CD3 and express variable levels of CD16, CD56 and CD57. In recent years NK cells have been categorised into two major groups based on the level of CD56 expression. This phenotypic classification correlates with functional activity as CD56bright NK cells are the major cytokine producing subset(More)
Natural killer (NK) cells rapidly reconstitute following allogeneic stem cell transplantation (allo-SCT), at the time when alloreactive T cell immunity is being established. We investigated very early NK cell reconstitution in 82 patients following T cell-depleted allo-SCT. NK cell number rapidly increased, exceeding T cell reconstitution such that the NK:T(More)
