Design outcomes

Primary

MeasureTime frame
The analysis of our data showed a significant high frequencies of CD4+CD8+ (double positive) T cells, CD4-CD8- (double negative) T cells and natural killer T cells in the peripheral blood of both BTM groups (splenectomized and non-splenectomized) as compared to healthy controls.
